5What 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 in Where you are nowThe step above
Technical Approach for a New Research Problem Proposes 1-2 options, requires detailed review and approval from Lead Research Engineer. Proposes a primary approach with alternatives, gets feedback from peers, requires manager approval. Defines the technical approach, gets peer review, informs Lead Research Engineer (unless it's a major strategic shift).
Tool/Library Selection for a Project Suggests tools from a pre-approved list, requires manager approval. Researches and proposes new tools, requires manager approval and team consensus. Selects tools from approved list; proposes and champions new tools, leading the evaluation and gaining team consensus. Informs Lead Research Engineer.
Cloud Resource Allocation (e.g., GPU instances) Requests specific resources from manager, providing justification. Estimates resource needs for their project, requests approval from manager. Manages cloud resource budget for their workstream (up to roughly £10K/quarter), optimising usage. Informs Lead Research Engineer of significant changes.
Mentorship & Guidance for Junior Engineers Asks questions and learns from senior team members. Offers informal help and answers questions from new joiners. Provides structured mentorship, detailed code reviews, and technical guidance to 1-2 junior engineers, helping them develop their skills.

6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

Research Project Completion Rate
The percentage of assigned research workstreams or projects that reach a defined 'prototype complete' or 'conclusion' stage within the agreed timeframe.
Target · 80% of projects completed or concluded within ±15% of initial estimate.

Leading the 'Diffusion Models for Data Synthesis' project from initial literature review to a working, benchmarked PoC in 3 months, as planned.

Experiment Rigour Score
A qualitative score (1-5) based on the clarity of experiment design, statistical soundness, reproducibility, and thoroughness of documentation for each major experiment.
Target · Average score of 4.0+ across all major experiments.

Your experiment on a new attention mechanism clearly defines hypotheses, uses appropriate statistical tests, and includes all code, data, and environment configurations for perfect reproduction.

Tech Transfer Readiness
The number of research prototypes or libraries that are deemed 'production-ready' by a product engineering team, meaning they meet basic code quality, performance, and documentation standards.
Target · At least 1 major prototype or library per year is accepted for tech transfer.

The 'Real-time Anomaly Detection' algorithm you developed is picked up by the Product team for integration into the next platform release.

Mentorship Impact
Feedback from junior team members on your guidance, code reviews, and technical support, measured through informal surveys and direct feedback to your manager.
Target · Consistently positive feedback, with at least one mentee showing clear skill progression (e.g., taking on more complex tasks independently).

A junior engineer you've been mentoring successfully leads their first small experiment, attributing their confidence to your support and detailed code reviews.

Technical Leadership & Influence
Your ability to guide technical discussions, propose sound architectural choices, and influence the technical direction of your projects and workstreams.
  • You're regularly asked for your opinion on technical challenges
  • your proposals for new tools or methodologies are often adopted
  • you lead technical deep-dives and design sessions effectively.
Problem Decomposition & Novelty
How well you break down complex, ambiguous research problems into manageable, testable components, and your ability to propose genuinely novel solutions, not just incremental improvements.
  • You present clear, structured research plans for ambiguous problems
  • your proposed solutions often involve adapting concepts from disparate fields or introducing entirely new approaches
  • you identify non-obvious root causes for model failures.
Collaboration & Knowledge Sharing
Your effectiveness in working with other teams (Product, Engineering) and sharing your research findings and expertise within the R&D department.
  • You proactively share research findings in internal seminars
  • you're sought out by other teams for technical advice
  • you contribute actively to our internal knowledge base and documentation.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy
Solving Hard, Uncharted Problems

You get a real kick out of tackling problems where there isn't an obvious answer in a textbook. You enjoy the process of exploration and discovery.

Spending a week trying five different approaches to a novel data synthesis problem, and finally finding a combination that shows promise.

Building Tangible Prototypes

While you love the theory, you're ultimately driven by seeing your ideas transform into working code, even if it's just a proof-of-concept. You like to build things.

Successfully getting a complex neural network to train and make predictions on a new dataset, even if it's not yet production-ready.

Continuous Learning & Growth

You're always reading, experimenting, and trying new things. The idea of staying stagnant technically is your worst nightmare.

Voluntarily diving into a new ML framework or reading up on the latest generative AI models in your spare time.

What frustrates people
  • The 'Reproducibility Gauntlet': Spending a month just trying to get a SOTA paper's results to work, often failing.
  • The Data Bottleneck: Constantly waiting for or cleaning data, rather than building models.
  • The 'Bug or Math?' Dilemma: Not knowing if your model isn't converging due to a coding error or a theoretical flaw.
  • Strategic Whiplash: Projects being cancelled after significant investment due to changing business priorities.
  • The Tech Transfer Impasse: Building a great prototype that never gets productionised by the product team.
  • Explaining Statistical Significance: Trying to convince non-technical stakeholders that a small percentage improvement is actually a big deal.
  • The 'Just Ship It' Pressure: Being asked to cut corners on experimental rigour for faster (but potentially flawed) results.
What this role does not give you
  • A predictable, linear path where every experiment yields a clear, positive result.
  • Guaranteed production deployment for every successful prototype you build.
  • Minimal interaction with non-technical teams or the need to 'translate' your work.
  • A role where you can avoid the messy, frustrating parts of data preparation and cleaning.

8Who you work with

This role directly influences the technical feasibility and direction of our core R&D initiatives. Your successful prototypes can unlock new product lines or significantly improve existing ones, directly contributing to our long-term growth and market position. Getting it wrong means wasted resources and missed opportunities for innovation.

Inside the business
  • Lead Research Engineers (your direct manager and peers)
  • Product Managers (to understand business needs and potential applications)
  • Software Engineers (for eventual tech transfer and productionisation)
  • Data Scientists (for data access and understanding existing models)
Outside the business
  • Academic collaborators (for joint research projects or knowledge sharing)
  • Technology vendors (for evaluating new tools or platforms)

9What you need before you start

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

  • Proven experience (5+ years) in a research-focused ML/AI role, with a track record of delivering working prototypes.
  • Deep understanding of at least one major ML framework (PyTorch or TensorFlow) and its ecosystem.
  • Strong software engineering fundamentals, including clean code practices, testing, and version control.
  • A solid grasp of linear algebra, calculus, probability, and statistics as applied to machine learning.
  • Experience leading technical aspects of research projects, not just executing tasks.

10What to practise next

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

Distributed Systems for ML

As models get bigger and datasets grow, training on a single machine is quickly becoming impractical. You'll need to understand how to effectively scale your research workloads across multiple GPUs and machines.

Data Parallelism vs. Model Parallelism · Distributed Training Frameworks (e.g., PyTorch Distributed, Horovod) · Fault Tolerance & Checkpointing · Optimising Network Communication

  • This month: Complete an online course or tutorial on distributed PyTorch or TensorFlow.
  • Month 2: Re-implement a small model to train using a distributed strategy on a multi-GPU machine or small cluster.
  • Month 3: Benchmark the performance of your distributed setup against a single-device training, identifying bottlenecks.

Quick win: Familiarise yourself with the basic concepts of distributed computing. Even if you're not implementing it, understanding the principles will help you debug and optimise.

Advanced MLOps & Productionisation

The line between research and production is blurring. You'll increasingly need to think about how your prototypes can seamlessly transition to production, meaning more focus on robust pipelines, monitoring, and versioning beyond just code.

Model Versioning & Registry · CI/CD for ML (CI/CD4ML) · Model Monitoring & Alerting · Feature Stores

  • This month: Read up on MLOps best practices and common patterns (e.g., Google's MLOps maturity model).
  • Month 2: Work closely with a product engineer to understand their deployment pipeline and identify friction points for your research outputs.
  • Month 3: Implement a basic CI/CD pipeline for a small experimental model, automating its testing and deployment to a staging environment.

Quick win: Whenever you build a new model, start thinking about how it would be deployed. What are the dependencies? How would you monitor it? What could go wrong?

11Staying current once you are in

What people here do to keep up
  • Regularly attending and presenting at relevant industry conferences (e.g., NeurIPS, ICML, CVPR, EMNLP) to stay current and network.
  • Contributing to open-source ML projects or maintaining your own research repository on GitHub.
  • Participating in online courses or specialisations on new ML techniques, MLOps, or distributed computing.
  • Engaging in internal R&D seminars, journal clubs, and knowledge-sharing sessions.
  • Mentoring junior colleagues and actively participating in code reviews to sharpen your own skills and help others.

  • Context Windows & Token Limits
  • Temperature Settings for Different Tasks
  • RAG (Retrieval Augmented Generation) Architectures
  • Output Validation & Hallucination Detection
  • Prompt Chaining for Complex Analysis

Responsible AI & Explainable AI (XAI)

As our models get more complex and move closer to production, understanding why they make certain decisions and ensuring they're fair and unbiased isn't just a 'nice to have'—it's a regulatory and ethical imperative. We need to build trust in our AI.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, research engineering isn't just about brilliant ideas; it's also about a lot of grunt work: digging through papers, writing boilerplate code, and endless hyperparameter tuning. What if you could offload a big chunk of that? Good news: you can. AI is already here to make your life easier.

We're not just talking about using AI in your models; we're talking about using AI to build those models faster. Imagine spending less time on the tedious bits and more time on the truly novel, impactful research. Here's how AI tools can genuinely change your day-to-day as a Senior Research Engineer.

Automated Hyperparameter Sweeps

Stop manually tweaking learning rates. Use intelligent AI-driven tools like Weights & Biases Sweeps or Optuna, often integrated with an LLM, to automatically explore the optimal model parameters. These tools don't just run experiments; they learn from previous runs, guiding you to the best configurations and automatically generating detailed reports on the top performers. This means less manual tracking and more actionable insights.

AI-Powered Literature Review

Drowning in arXiv papers? AI research assistants (think Elicit or Scispace) are game-changers. Feed in a foundational paper, and these tools will instantly find, summarise, and categorise dozens of related works. They'll even highlight contradictory findings, point out methodological differences, and help you identify gaps in the existing research. It's like having a super-fast research assistant that never gets tired.

Copilot for Prototyping

Spend less time writing repetitive code and more time on the actual innovation. Tools like GitHub Copilot are fantastic for generating boilerplate code for data loading, pre-processing, visualisation, and even model scaffolding. This frees your brain to focus on the truly novel parts of your algorithm, rather than getting bogged down in the setup. It's like having an experienced pair programmer constantly by your side.

Documentation & Update Generation

After a sprint of experiments, you've got a pile of notes, code snippets, and W&B charts. Instead of spending hours writing up reports, feed that raw information into an LLM. It can generate a first draft of a Confluence update page, a concise progress summary for your stakeholders, or even help structure the methods section for a patent application. It won't be perfect, but it'll save you a significant chunk of time.
