1What this role really is

This isn't just about writing code; it's about building the brains for the future of our energy grid. You'll be designing, building, and owning critical software components that help us understand, predict, and optimise how electricity flows. Think complex algorithms, real-time data, and a direct impact on keeping the lights on (and green). It's a proper technical role where you're expected to get your hands dirty with the physics of power systems as much as with clean code.

2What you'd actually use

The tools this job runs on, and how well you'd need to know each one.

Python (pandas, NumPy, SciPy, PyPSA, pandapower)Advanced/Expert

Designing and building custom libraries for energy modelling, implementing complex optimisation algorithms, and mentoring junior engineers on best practices. You'll use it for everything from data analysis to building core grid applications.

Grid Simulation Software (PSCAD, PSS/E, OpenDSS)Advanced/Expert

Designing complex, multi-scenario simulations, building custom models of new assets (e.g., grid-forming inverters), and deeply analysing simulation outputs to validate models or understand grid behaviour. You'll be spending a lot of time in these.

Time-Series Databases (TimescaleDB, InfluxDB, OSIsoft PI)Advanced/Expert

Designing data schemas and ingestion pipelines for large-scale time-series data, optimising query performance for real-time analytics, and extracting insights from historical grid data. You'll be working with huge datasets.

Cloud Platforms (AWS Kinesis, Lambda, Kubernetes (EKS))Advanced/Expert

Building and managing data processing pipelines, deploying and managing containerised applications on Kubernetes, and making informed decisions about cloud service selection for scalability and reliability. You'll be a cloud native.

Containerization (Docker, Kubernetes)Advanced/Expert

Writing optimised Dockerfiles for production environments, managing container orchestration using Kubernetes manifests and Helm charts, and ensuring our applications are robust and portable. You'll be thinking microservices.

GIS Software (QGIS, Esri ArcGIS)Advanced/Expert

Performing complex spatial analysis to correlate grid asset data with geographical features (e.g., vegetation encroachment, weather patterns), and integrating spatial insights into grid models. You'll see the grid on a map.

Grid Protocols (DNP3, IEC 61850, Modbus)Advanced/Expert

Developing software that communicates directly with field devices using these protocols, debugging protocol-level communication issues, and understanding the nuances of real-time data acquisition from substations. This is where software meets hardware.

4How you'll be judged

The scoreboard, honestly: the hard targets, how often each one is actually looked at, and the quiet human signals that never make it onto a dashboard.

Model Accuracy & Reliability
The precision and consistency of your power system models and simulations.
Target · Achieve <2% deviation in key operational forecasts (e.g., load, generation) and <0.5% error rate in real-time state estimation results.

Your new state estimation algorithm consistently predicts bus voltages within 0.1% of actual SCADA measurements, reducing false alarms for the operations team by 15% in Q2.

System Performance & Optimisation
How efficiently and quickly your software components run, especially for optimisation tasks.
Target · Reduce Optimal Power Flow (OPF) solve times by 15% for typical scenarios, allowing for more frequent dispatch decisions. Ensure new features add no more than 5% latency to existing real-time processes.

Your refactoring of the congestion management module cut its execution time from 120 seconds to 95 seconds, enabling the market team to run two extra optimisation cycles daily.

Project Delivery & Technical Leadership
Your ability to lead and deliver significant technical workstreams, often guiding junior engineers.
Target · Lead and complete 80% of assigned major workstreams (e.g., a new DER integration module) on schedule and within agreed technical specifications. Successfully mentor at least one junior engineer to take on independent ownership of a mid-sized feature within 12 months.

You led the implementation of the new grid-forming inverter model, delivering it two weeks early, and the junior engineer you mentored is now independently maintaining its documentation and running basic simulations.

Code Quality & Maintainability
The clarity, robustness, and test coverage of the code you produce and review.
Target · Maintain >90% code coverage for critical modules you own. Achieve <5 critical bugs reported per quarter for your code. Ensure code reviews consistently identify and resolve architectural issues before merging.

After your refactor, the power flow solver module now has 95% test coverage, and its complexity score (Cyclomatic Complexity) dropped by 20%, making it much easier for new team members to understand and modify.

Architectural Contribution
Your input and influence on the design of our energy systems software architecture.
  • You're regularly consulted on new system designs and technical approaches. Your proposals for architectural improvements are often adopted. You proactively identify technical debt and suggest strategies to address it. You can clearly articulate the trade-offs of different design choices to both technical and non-technical audiences.
Mentorship & Knowledge Sharing
How effectively you help develop other engineers and disseminate critical knowledge.
  • Junior engineers actively seek your advice and guidance. You run internal tech talks or workshops on complex topics. Your documentation is clear and comprehensive, making it easier for others to onboard or understand existing systems. You consistently provide constructive and actionable feedback during code reviews.
Problem-Solving & Innovation
Your ability to tackle novel, complex technical challenges and propose creative solutions.
  • You're the person who gets called when 'the model won't converge' and you can methodically debug it. You propose new algorithms or approaches that improve existing system capabilities. You can break down ambiguous problems into manageable, solvable components. You're not afraid to challenge existing assumptions with data and sound technical reasoning.
Cross-Functional Collaboration
How well you work with other teams, like Product, Operations, and Data Science.
  • You proactively engage with Product Managers to clarify requirements and manage expectations. You explain complex technical constraints to the Operations team in a way they understand. You get on well with Data Scientists, helping them integrate their models into production systems. You're known for being a good bridge-builder between different technical disciplines.

5Would you like it

The honest version. What people enjoy, and what grinds them down.

What people enjoy
Solving Hard, Real-World Engineering Problems

You get a kick out of tackling non-trivial challenges that combine physics, maths, and software. When a new market rule or grid behaviour needs to be modelled, you're excited to dig in. You enjoy the intellectual puzzle of making complex systems work.

Spending a week deep-diving into the control logic of a new type of battery inverter to accurately represent it in our grid simulation software, then seeing that model successfully predict its behaviour in a real-world scenario.

Direct Impact on the Energy Transition

You're driven by the knowledge that your code is directly contributing to a cleaner, more resilient energy future. You want your work to have a tangible, positive environmental and societal impact, not just generate profit. You see the bigger picture.

Developing a new optimisation algorithm that allows us to integrate an additional 50MW of intermittent solar power onto the grid without compromising stability, knowing that's 50MW less from fossil fuels.

Continuous Technical Growth & Mastery

You're always learning new algorithms, diving into academic papers, or experimenting with new programming paradigms. You want to be the go-to expert in a specific domain like Optimal Power Flow or DER modelling, and you actively seek out opportunities to deepen your technical knowledge.

Taking the initiative to learn the intricacies of IEC 61850 protocol in your spare time, then proposing a new way to interface with substation devices that significantly improves data latency for our real-time applications.

What frustrates people
  • Dealing with legacy systems and data formats that feel like they're from another century.
  • Explaining fundamental physics constraints to stakeholders who just want the 'magic button'.
  • Spending more time cleaning and validating data than actually building models.
  • The unpredictable nature of real-world grid operations versus clean simulation environments.
  • Regulatory changes that force significant rework on already complex systems.
  • Being asked to 'just fix the software problem' when the issue is actually a deep power systems engineering challenge.
What this role does not give you
  • A purely greenfield development environment with no legacy code to maintain.
  • A role where you can ignore the underlying physics and focus solely on software patterns.
  • A predictable, unchanging set of requirements or technical challenges.
  • A role with minimal interaction with non-technical stakeholders or external partners.
  • An environment where every piece of code you write makes it to production without significant iteration or adaptation.

6Who you work with

This role directly impacts our ability to innovate within the energy sector. Your software helps us integrate more renewable energy, improve grid reliability, and reduce operational costs. You're building the tools that allow us to make data-driven decisions about multi-million-pound infrastructure investments and real-time grid control.

8What to practise next

Where the job is going, and what to do about it starting this week.

Advanced Numerical Methods & Optimisation

As grid complexity increases with more renewables and flexible demand, we'll need to solve larger, more non-linear, and often non-convex optimisation problems in real-time. Your understanding of advanced numerical methods will be critical for developing faster, more robust solvers.

Interior-Point Methods · Convex Optimisation · Stochastic Optimisation · Distributed Optimisation · High-Performance Computing (HPC) Techniques

  • This week: Review the latest academic papers on advanced OPF solvers and numerical stability.
  • This month: Experiment with a new optimisation library (e.g., JuMP.jl, CVXPY) to solve a challenging power system problem.
  • Month 2: Explore how to parallelise a computationally intensive part of one of our existing simulation models using Dask or similar.
  • Month 3: Present a proposal for how we could improve the performance or robustness of our current OPF engine using new numerical techniques.

Quick win: Pick one of our existing optimisation problems and try to formulate it using a different solver or library to see if you can achieve better performance or robustness.

Cyber-Physical System Security

The convergence of IT and OT in energy systems creates new attack surfaces. As our software directly interacts with physical grid assets, understanding the unique security challenges of cyber-physical systems (CPS) will become paramount to prevent malicious actors from disrupting the grid.

Threat Modelling for CPS · Intrusion Detection for Grid Data · Resilient Control System Design · Secure Coding Practices for Embedded Systems · Supply Chain Security for OT

  • This week: Read up on recent cyberattacks on critical infrastructure (e.g., Colonial Pipeline, Ukrainian power grid).
  • This month: Take an online course or read a book on cyber-physical system security or industrial control system security.
  • Month 2: Conduct a basic threat model for one of our existing grid-facing software components, identifying potential vulnerabilities.
  • Month 3: Propose specific secure coding guidelines or testing procedures that we could adopt to improve the security posture of our energy systems software.

10How the AI economy is changing work like this

Before we ask anything of you, here's what we can already say about AI and work of this kind:

The new skill this role is being asked for: Prompt Engineering & LLM Integration for Technical Tasks

Honestly, competitors are already using large language models (LLMs) to draft complex reports in minutes that used to take hours. Engineers who figure out how to effectively use these tools for coding, debugging, documentation, and even initial algorithm design will outproduce their peers significantly. This isn't future tech; it's happening now.

We'll only ever tell you what we can actually back up. No hype, no scare tactics.

The ten Future Fluencies

Zavmo analysis

The credential is what you can do today. These are what keep you valuable.

A qualification proves you can do the job as it's defined today. These ten are what decide whether you're still the obvious person for it in five years. They're the capabilities employers are now writing into senior roles faster than people are learning them. Zavmo weaves them through whatever you study, so you come out with both: the credential and the fluency.

The highlighted ones are the Fluencies your role leans on hardest, from how Senior Energy Systems Software Engineer is actually changing. In about two minutes, the free confidence check asks where you stand on each of the ten. That's the whole check, and it's what makes the plan yours rather than generic.

No two people run this the same way

A course is written once and handed to everyone. This is assembled around you, and keeps changing as it learns you. Five things it reads, and what each one changes.

  1. Your actual work Every lesson is taught against a live piece of your own work, not a worked example from a textbook.
  2. What you already know The first conversation finds your starting point, so you skip what you can already do and spend the time on what you cannot.
  3. The conditions you learn under Not a learning-styles quiz. The evidence does not support those. The dimensions the research does back, read once and used to shape the plan.
  4. How far you got last time It picks up mid-thought. The tutor knows what you said, what you struggled with, and what it asked you to try.
  5. Which tutor suits the moment Twelve of them, each for a different kind of thinking. The one who walks you through a first idea is not the one who stress-tests it.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, a lot of what we do as engineers involves repetitive tasks, digging through documentation, or wrestling with messy data. AI isn't here to replace you; it's here to give you superpowers, freeing you up to focus on the really hard, interesting problems that actually need your brain.

For a Senior Energy Systems Software Engineer, AI can be a game-changer. Imagine cutting down on tedious model calibration, getting predictive insights faster, or instantly understanding dense regulatory documents. These tools are already available, and we're actively encouraging our team to use them to work smarter, not harder.

Automated Model Calibration

Use AI (like Bayesian optimisation) to automatically tune thousands of parameters in a power system model – think line impedances, load profiles – to match real-world data. This used to be a manual, tedious, and often suboptimal process. Now, let the AI do the heavy lifting.

Predictive Fault Analysis

Train machine learning models on historical SCADA and weather data to predict the probability of equipment failure (e.g., a transformer overheating) in the next 24 hours. This shifts our focus from reactive maintenance to proactive intervention, saving huge amounts of time and money.

Regulatory & Research Synthesis

Point an LLM at those dense, 500-page regulatory filings from Ofgem or NERC. It'll summarise them, extract key technical requirements, and highlight compliance obligations that would otherwise take you days to read and digest. Instant knowledge, less eye strain.

Auto-Generating Model Documentation

Feed your complex simulation model's codebase (in Python or MATLAB) into an AI tool and have it generate human-readable documentation. It'll explain the physical assumptions, inputs, and outputs, drastically improving knowledge transfer and making onboarding new team members a breeze. Future-you will be grateful.

The honest bit

You’ve started things before

Most of them were built for a room full of people who aren’t you. A cohort moves on whether or not your week allowed it, and by the third week the thing you’re behind on becomes the reason you stop opening it.

There’s no cohort here, and no timetable to fall behind. Before anything starts, Zavmo asks when you’re sharpest and how long you can realistically sit down for, then builds the sessions around those answers. A bad fortnight changes your pace. It doesn’t put you behind.

And you only pay once you start learning. Searching and planning are free, and you can cancel any time — so the cost of finding out is an afternoon, not a year.

What it costs

Less than one coaching session. Every month.

A single career-coaching hour costs more than a month of this, and it ends when the hour does. Zavmo doesn't. It's £70 a month, about £2.30 a day, for a companion that knows a Senior Energy Systems Software Engineer, works on the job you actually do, and keeps going at your pace rather than a timetable's.

  • Searching and planning stay free. You only pay when you start learning.
  • Your credits are yours. Regulated, and they don't vanish when a subscription ends.
  • Cancel any time and billing stops. No notice period, no minimum term.

Your path, personalised

You have the map. Walking it is the part we do together.

Other roles in Technical roles

Stay in the field you know and move sideways rather than up.

If you leave this industry

The skills you'll gain here are highly transferable within the broader energy sector (e.g., utilities, renewable energy developers, energy market operators, grid technology providers) and even to other complex engineering domains (e.g., aerospace, defence, industrial automation) that deal with real-time control and cyber-physical systems. Your deep understanding of complex systems, robust software engineering, and critical infrastructure makes you a valuable asset.
