3What you get to decide, and how that grows

Power in a job isn't your title. It's what you're allowed to decide. Here's how it grows as you move up.

The choiceComing inWhere you are nowThe step above
Technical Architecture for a New ML SystemProposes initial ideas for components, needs full review and approval from a Senior or Lead Engineer.Designs a significant portion of the system, consults with Senior/Lead on major decisions, gets approval from Lead.Leads the design of the entire ML system, makes technical decisions within scope, consults Lead on strategic trade-offs or major cross-team dependencies.
Model Deployment StrategyExecutes deployment steps under close supervision, follows existing runbooks.Independently deploys models using established CI/CD pipelines, troubleshoots minor issues.Designs and implements the deployment strategy for new model types or services (e.g., canary deployments, blue/green), owns the associated CI/CD pipelines, and sets standards for others.
Cloud Resource OptimisationIdentifies obvious cost-saving opportunities (e.g., forgotten resources), escalates to senior team.Implements cost-saving measures within existing infrastructure (e.g., rightsizing instances) with manager approval.Architects cost-optimised solutions for entire ML workloads, makes recommendations for significant infrastructure changes, and is accountable for meeting cost targets for owned systems.
Mentee Technical GuidanceAsks questions and seeks guidance from senior team members.Provides informal advice and code review comments to peers.Provides structured mentorship, leads code reviews for mentees, helps them unblock technical challenges, and provides input on their performance and development plans.

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.

ML Service Uptime
The percentage of time your deployed machine learning services are available and responding to requests.
Target · Maintain 99.95% uptime for owned services (e.g., inference APIs, retraining pipelines).

If your fraud detection model's API is down for 20 minutes in a month, that's a serious incident that impacts this metric. We're looking for consistent, near-perfect availability.

Inference Latency (p99)
The time it takes for 99% of requests to a deployed model to return a prediction. This is critical for real-time applications.
Target · p99 latency < 100ms for critical real-time models.

If our recommendation engine takes longer than 100ms for 1% of users, they might have a bad experience. You'll need to optimise the system to keep this tight.

Cost Optimisation for ML Workloads
Reducing the cloud infrastructure costs associated with model training, serving, and data processing for your owned systems.
Target · Reduce model training/serving costs by 15% year-on-year for your assigned systems.

Identifying and implementing a strategy to use AWS Spot Instances for non-critical training jobs, saving £500 per month on compute costs.

Deployment Success Rate & Rollbacks
The percentage of model deployments that complete successfully without needing a rollback due to production issues.
Target · >98% of deployments succeed without rollback; <1 critical bug found in production post-deployment per quarter.

You push a new model version, and it causes a spike in errors or bad predictions, forcing a rollback. We want to see this happen very rarely, if at all.

Mentee Development & Impact
The growth and successful contribution of junior engineers you mentor.
Target · 1-2 mentees successfully promoted or take on more senior responsibilities within 18 months, or demonstrate significant independent contribution.

A junior engineer you've been mentoring successfully takes ownership of a smaller ML pipeline, independently debugging issues and proposing improvements, directly attributable to your guidance.

System Design Quality & Maintainability
How well-designed, robust, and easy-to-maintain your ML systems are, considering future changes and potential failures.
  • Positive feedback in code reviews for architectural choices
  • systems rarely require emergency fixes
  • new features can be added without major refactoring
  • comprehensive and up-to-date documentation that others can easily follow.
Proactive Problem Solving & Risk Mitigation
Your ability to anticipate potential issues in ML pipelines or deployed models and address them before they become critical problems.
  • Identifying and flagging potential model drift before performance degrades significantly
  • proposing and implementing monitoring alerts for edge cases
  • proactively addressing technical debt in critical systems
  • identifying upstream data quality issues before they break your models.
Cross-Functional Collaboration & Influence
How effectively you work with data scientists, product managers, and other engineering teams to deliver ML solutions.
  • Data scientists actively seek your input on model deployment strategies
  • product managers rely on your estimates for ML feature delivery
  • you're able to get agreement from different teams on shared infrastructure standards
  • feedback from peers highlights your ability to translate complex technical concepts.
Technical Leadership & Mentorship
Your ability to guide and develop junior engineers, sharing knowledge and best practices.
  • Junior engineers consistently improve their code quality and problem-solving skills under your guidance
  • you lead technical discussions or workshops
  • you provide constructive and actionable feedback in code reviews
  • you're seen as a go-to person for technical advice within the team.
Documentation & Knowledge Sharing
The quality and completeness of the documentation for your owned systems and your contributions to team knowledge.
  • Well-structured and current system diagrams
  • clear READMEs for repositories
  • internal wiki pages explaining complex ML concepts or deployment patterns
  • regular contributions to team knowledge bases or internal tech talks.

5Would you like it

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

What people enjoy
Building Robust Systems that Actually Work

You get a real kick out of seeing your ML pipelines run smoothly, your models deployed reliably, and knowing that the systems you've built are delivering value without constant babysitting. You love the challenge of making complex things simple and stable.

Spending a day refactoring a messy deployment script into a clean, automated CI/CD pipeline that now deploys new models with a single click, and then seeing it work perfectly.

Solving Tricky Technical Puzzles

You thrive on debugging complex issues across distributed systems, optimising model serving latency, or figuring out how to scale a training job efficiently. The harder the technical problem, the more engaged you are.

Spending an afternoon profiling a slow inference service, identifying a bottleneck in a specific library, and then implementing a clever caching strategy that halves the latency.

Mentoring and Sharing Knowledge

You enjoy helping junior engineers get unstuck, reviewing their code to offer constructive feedback, and explaining complex MLOps concepts in a way that clicks for them. You like seeing others grow because of your input.

Guiding a new joiner through their first model deployment, helping them understand the nuances of containerisation and monitoring, and seeing them successfully push their model to production.

What frustrates people
  • The 'Jupyter-to-Production Chasm': Spending 60% of your time rewriting, refactoring, and testing a data scientist's experimental notebook code to make it robust and scalable for production.
  • Mysterious Upstream Data Breaks: Your perfectly stable model pipeline suddenly fails at 2 AM because a different team changed a schema in a source database without telling anyone.
  • 'It Works on My Machine': The endless battle of debugging environment inconsistencies between a local dev setup, the CI/CD runner, and the production server.
  • Infrastructure Babysitting: Spending more time managing Kubernetes configurations, IAM permissions, and cloud networking rules than actually building ML systems.
  • The Hype vs. Reality Gap: Explaining to leadership that 'AI' can't magically solve a business problem when the underlying data quality is terrible and the requirements are undefined.
What this role does not give you
  • A purely academic research environment; this is about building and shipping.
  • A role where you only train models and don't care about how they run.
  • A predictable, unchanging tech stack; things move fast here.
  • A role with minimal interaction with other teams; collaboration is key.

6Who you work with

This role directly drives the reliability, scalability, and performance of our core machine learning products and internal tools. Your work ensures that the insights and predictions generated by our data science team are actually usable and impactful. You're essentially the backbone that supports our entire ML-driven strategy, making sure our 'AI' isn't just a buzzword, but a functioning reality.

Inside the business
  • Data Scientists (your primary 'clients')
  • Product Managers (who define what needs building)
  • Software Engineering Teams (who use your services)
  • Cloud Operations/DevOps (who help you deploy and monitor)
  • Senior Leadership (who want to see the impact of ML)
Outside the business
  • Key Vendors (e.g., cloud providers, MLOps platforms)

7What you need before you start

Not a wish list. The things you would be expected to already have.

  • You'll need at least 5 years of hands-on experience as a Machine Learning Engineer or a very closely related role (e.g., Data Engineer with heavy ML focus, Backend Engineer building ML services).
  • A solid track record of independently building, deploying, and maintaining at least two end-to-end machine learning systems in a production environment.
  • Demonstrable experience with cloud platforms (AWS, GCP, or Azure) for ML workloads, not just using them, but actually architecting solutions on them.
  • Strong software engineering fundamentals, including writing clean, testable Python code and using version control (Git) effectively.
  • Experience mentoring junior engineers or leading small technical projects, even informally.

8What to practise next

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

Feature Stores & Data Contracts

Ensuring consistency between training and serving data is a perpetual headache. Feature stores solve this, and data contracts formalise expectations between data producers and consumers. This is critical for scaling ML and reducing 'serving skew'.

Offline vs. Online Feature Serving · Feature Versioning & Lineage · Data Contract Definition (e.g., using Great Expectations) · Feature Engineering at Scale

  • This week: Read up on popular feature store solutions like Feast or Tecton. Understand their core concepts and benefits.
  • This month: Identify one existing ML model in our stack that suffers from serving skew. Propose how a feature store could mitigate this.
  • Month 2: Experiment with a lightweight feature store (e.g., using a Redis cache for online features) for a non-critical model. Document your findings.
  • Month 3: Work with a data engineering team to define a data contract for a critical upstream data source, focusing on schema enforcement and data quality checks.

Quick win: Start documenting the features used by your current models much more rigorously, including their definitions, sources, and transformation logic. This is the first step towards a feature store.

ML Model Observability & Explainability (XAI)

It's not enough for a model to just make predictions; we need to know *why* it made them and *how* it's performing in the wild. Regulations and business needs demand greater transparency and the ability to detect issues beyond simple accuracy metrics.

Model Drift & Concept Drift Detection · Data & Prediction Monitoring · SHAP & LIME for Local Explainability · Global Explainability Techniques · Adversarial Robustness Testing

  • This week: Integrate a basic model monitoring library (e.g., Evidently AI, WhyLabs) into one of your existing ML pipelines.
  • This month: Set up alerts for significant deviations in key input feature distributions or prediction outputs for a deployed model.
  • Month 2: Experiment with SHAP or LIME to generate explanations for a model's predictions. Discuss the insights with the data scientist who built the model.
  • Month 3: Research and propose a strategy for systematically monitoring for model drift across our critical production models, including what metrics to track and how to alert.

Quick win: Add basic data quality checks to the beginning of your ML pipelines and monitor the distribution of your model's predictions. If the data or predictions suddenly look weird, you'll know something's up.

9Staying current once you are in

What people here do to keep up
  • Actively participate in ML engineering communities (e.g., MLOps.community, local meetups, online forums).
  • Contribute to open-source ML/MLOps projects where possible.
  • Attend industry conferences (e.g., KubeCon, ODSC, Re:Invent) to stay current with trends and network.
  • Take advanced online courses or specialisations in areas like distributed systems, advanced MLOps patterns, or specific cloud ML services.
  • Lead internal tech talks or workshops to share your knowledge and expertise with the team.

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

Large Language Models (LLMs) are transforming how we interact with data and automate tasks. Competitors are already using them to draft reports in 10 minutes that used to take 2 hours. Engineers who master this will outproduce their peers significantly. It's not just about using ChatGPT; it's about integrating LLMs into our production systems reliably.

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

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 ML Engineers involves repetitive tasks, digging through documentation, or writing boilerplate code. What if you could offload a good chunk of that to AI? We're not talking about replacing you; we're talking about giving you a superpower.

Our team actively uses AI-powered tools to make our lives easier and our work more impactful. You'll be expected to embrace these tools, not just for efficiency, but to free up your brain for the really hard, interesting problems. Here's how AI will actually help you day-to-day as a Senior Machine Learning Engineer.

Code Automation & Refactoring

Use AI assistants like GitHub Copilot or Tabnine to instantly generate boilerplate for FastAPI endpoints, Dockerfiles, Kubernetes YAML configs, or unit test skeletons. Need to refactor a messy data scientist's notebook into clean, production-ready Python? AI can suggest improvements, identify redundant code, and even help you write more efficient algorithms. It's like having a pair programmer who never sleeps.

Performance Anomaly Detection

Instead of manually sifting through endless logs, train an AI to analyse system logs and performance metrics (think inference latency, CPU/memory usage, model prediction distributions) to proactively flag potential model drift or infrastructure degradation. It'll tell you when something looks 'off' before it causes an outage, letting you debug smarter, not harder. This means fewer 2 AM pager alerts, hopefully!

Research Paper & Tech Doc Summarisation

Stay on top of the rapidly evolving ML landscape without drowning in dense text. Use large language models (LLMs) to quickly summarise academic papers on new model architectures, complex documentation for a new cloud service, or lengthy internal RFCs. Extract key concepts, identify relevant code examples, and get the gist in minutes, not hours. It's like having a personal research assistant.

Automated Documentation & Diagrams

Documentation is crucial, but let's be honest, it's often a chore. Leverage AI tools that parse your code and infrastructure-as-code files (like Terraform or Kubernetes manifests) to automatically generate and update system architecture diagrams and technical documentation in Confluence. This means less time writing about what you built, and more time actually building it. Future-you (and your teammates) 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 Machine Learning 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.
