3What this role really is

A Research Engineer turns academic research into working code and early prototypes. You work with complex algorithms, testing whether published research holds up in practice. You take an idea from a paper, write the code, and see whether it delivers real value. This work builds the foundations for future products.

4What you'd actually use

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

PyTorch or TensorFlow Intermediate

Implementing and training neural networks for various research tasks, often adapting established architectures from papers. You'll be writing custom training loops and model components.

scikit-learn Proficient

Building baseline models, performing feature engineering, and running classical machine learning algorithms for comparison or simpler tasks.

Weights & Biases (W&B) or MLflow Intermediate

Logging experiment metrics, model artefacts, and hyperparameters. Building comparison dashboards to track performance across different runs and share results with the team.

Python (pandas, NumPy) Strong

The primary language for all research and prototyping. You'll use pandas for data manipulation and NumPy for numerical operations, writing clean, functional code within existing projects.

SQL Basic

Extracting and querying data from our internal databases for experimental datasets. You should be able to write basic SELECT statements and understand joins.

Docker Basic

Running and modifying existing Docker containers to ensure reproducible research environments. Understanding what a Dockerfile does to package your code and dependencies.

AWS (S3, EC2) Intermediate

Using S3 for storing large datasets and model checkpoints, and spinning up EC2 instances (often with GPUs) to run your experiments. You should be comfortable navigating the AWS console.

Git (GitHub/GitLab) Intermediate

Managing your code with standard Git workflows: branching, committing, merging, and creating pull requests. This is non-negotiable for collaborative work.

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 Sub-Task Proposes options, needs approval from Senior Engineer. Decides on approach for routine tasks, consults Senior Engineer for novel ones. Expected to justify choice. Defines technical approach for entire workstream, informs Lead Engineer.
Experiment Design Assists in setting up experiments, design reviewed by Senior Engineer. Designs and executes experiments independently, reviews with Senior Engineer for complex setups. Designs complex experimental programmes, mentors others on best practices.
Code Implementation Details Implements code following existing patterns, all PRs reviewed. Independently implements new features/prototypes, code reviewed by peers/Senior Engineer. Defines coding standards, reviews complex PRs, designs new libraries.
Escalation of Roadblocks Escalates all significant technical or project roadblocks immediately. Attempts to solve routine roadblocks independently for a defined period (e.g., 1-2 days), escalates if no progress or if novel. Identifies and proactively addresses roadblocks, only escalates if beyond team's capacity or requires strategic input.

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.

Experiment Velocity
The number of distinct, documented experiments you run and analyse each quarter.
Target · 10-15 documented experiments per quarter

In Q2, you ran 12 experiments, each with clear hypotheses, results, and next steps documented in W&B, including three ablation studies on a new model architecture.

Code Quality & Reproducibility
How clean, well-tested, and reproducible your prototype code is, measured by code review feedback and ease of replication by others.
Target · <10% of merged pull requests require significant refactoring post-review; 90% of your experiments are fully reproducible.

Your latest prototype for a novel data augmentation technique was picked up by a new team member and they got it running with identical results in under an hour, thanks to your clear Dockerfile and documentation.

Research Reproduction Success Rate
The percentage of external research papers or concepts you attempt to reproduce that yield comparable results to the original publication.
Target · Successfully reproduce 2-3 key papers per year (or clearly document why reproduction failed).

You spent a month trying to reproduce a specific transformer architecture from an arXiv paper. While the initial results were off, you systematically debugged and identified a crucial pre-processing step the authors omitted, eventually getting within 1% of their reported accuracy.

Rigor of Experimental Design
Your ability to design experiments that isolate variables, control for biases, and produce statistically sound conclusions, even when the results aren't what you expected.
  • Your experiment logs show clear hypotheses, well-defined metrics, and a thoughtful approach to data splits. You can articulate the limitations of your experiments and potential confounding factors. Senior engineers rarely find flaws in your experimental setup.
Documentation Quality & Clarity
How well you document your research process, code, and findings, making it easy for others (and future you) to understand and build upon your work.
  • Your W&B dashboards are intuitive, your GitHub repos have clear READMEs, and your internal wiki pages explain complex ideas simply. Peers often refer to your documentation as a good example. (Yes, it's boring, but it matters!)
Proactive Problem Solving
Your initiative in identifying technical roadblocks, debugging complex issues, and proposing solutions without constant prompting.
  • You're the one who spots a weird anomaly in the training loss and digs into it before anyone else. You come to weekly check-ins with not just problems, but also 2-3 potential ways to tackle them. You don't just wait for instructions when things go wrong.
Collaboration & Knowledge Sharing
How effectively you work with other engineers and scientists, sharing your insights and learning from theirs.
  • You actively participate in team discussions, offer helpful code review feedback, and aren't afraid to ask for help when stuck. You present your findings in internal tech talks, even when they're not 'perfect' yet. You help new joiners get up to speed.

7Would you like it

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

What people enjoy
Solving Hard, Unsolved Problems

You thrive on wrestling with a model that won't converge, or trying to reproduce a paper where the authors conveniently 'forgot' a key detail. The bigger the puzzle, the more engaged you are.

Spending a week debugging a subtle memory leak in a PyTorch model, eventually tracing it back to an obscure interaction between two libraries, and feeling a huge sense of accomplishment when it's finally fixed.

The Thrill of Discovery

You love the moment when an experiment finally yields a breakthrough, or when you read a new paper and immediately see how it could apply to one of our challenges. It's about pushing the boundaries of what's possible.

Successfully implementing a novel loss function that significantly improves model performance on a tricky dataset, and immediately sharing your findings with the team.

Building Tangible Prototypes

You enjoy the process of writing code, setting up experiments, and seeing a theoretical concept come to life, even if it's just a messy proof-of-concept. You're a builder at heart.

Taking a complex algorithm for anomaly detection from a research paper and, within a few weeks, having a working Python prototype that can process our internal data and flag unusual patterns.

What frustrates people
  • The Reproducibility Gauntlet: Spending the first month of a project just trying to reproduce results from a SOTA paper, only to find the authors omitted a 'secret sauce' detail in their code or methods. It's infuriating.
  • The Data Bottleneck: Your progress is constantly gated by the availability of clean, well-labelled, and sufficiently large datasets. You'll often spend more time on data wrangling and cleaning than on innovative algorithm design.
  • The 'Is It A Bug or Is It The Math?' Dilemma: Your model isn't converging, and you spend days debugging, unable to tell if you have a simple coding error or a fundamental flaw in your theoretical approach. It's a real head-scratcher.
  • Strategic Whiplash: Pouring six months of your life into a promising research direction, only for the project to be cancelled overnight due to a C-level strategic pivot. It happens, and it's tough.
  • Explaining 'Statistical Significance': Trying to convince a non-technical stakeholder that a 2% improvement on a key metric is a massive breakthrough, while they see it as a trivial change. It's like speaking different languages.
  • The 'Just Ship It' Pressure: Being pressured by management to cut corners on experimental rigour to show faster progress, creating technical debt that will absolutely haunt the project later. It's a constant battle.
What this role does not give you
  • A perfectly linear, predictable career path where every project ships to production.
  • A guarantee that your innovative ideas will immediately become part of a product.
  • A role focused solely on production engineering or maintaining existing systems.
  • An environment where ambiguity is rare and all problems have clear solutions.

8Who you work with

This role is crucial for our innovation engine. You're directly responsible for proving the viability of new research directions, which means your work influences what features and capabilities make it into our future products. Essentially, you're laying the groundwork for what our company will be doing in the next 2-3 years, ensuring we're not just iterating on existing ideas but genuinely breaking new ground.

Inside the business
  • Senior Research Engineers
  • Lead Research Engineers
  • Product Managers (for potential tech transfer)
  • Data Scientists (for data insights)
  • Software Engineers (for productionisation discussions)
Outside the business
  • Academic Researchers (for collaboration and understanding new papers)
  • Open-source communities (for contributions and learning)

9What you need before you start

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

  • A Bachelor's or Master's degree in Computer Science, Machine Learning, AI, or a closely related quantitative field (or equivalent practical experience, we're flexible).
  • 2-5 years of hands-on experience in a research-focused role, ML engineering, or a similar position where you've built and experimented with ML models.
  • Demonstrable experience with Python for scientific computing and ML (e.g., personal projects, open-source contributions, academic research).
  • A portfolio or demonstrable project work (e.g., GitHub repo, academic papers) showing your ability to implement and evaluate ML algorithms.

10What to practise next

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

Advanced Optimisation Techniques

To squeeze out every bit of performance from models. As models get larger and datasets grow, efficient training and inference become paramount. You'll need to go beyond standard optimisers.

Quantisation & Pruning · Distributed Training Paradigms · Gradient Accumulation & Mixed Precision Training

  • This quarter: Experiment with mixed-precision training in PyTorch/TensorFlow on one of your existing models.
  • Next quarter: Research and implement a basic quantisation strategy for a prototype model.
  • Month 6: Explore using a distributed training framework for a larger experiment.
  • Month 9: Share your findings on optimisation techniques with the team, highlighting practical gains.

Quick win: Start profiling your model's training and inference times today to identify bottlenecks. You can't optimise what you don't measure.

11Staying current once you are in

What people here do to keep up
  • Regularly reading and critically evaluating new research papers on arXiv and leading conference proceedings (NeurIPS, ICML, ICLR).
  • Contributing to open-source ML projects or maintaining your own public GitHub repositories.
  • Attending relevant industry conferences, workshops, or meetups (e.g., PyData, local ML groups).
  • Participating in Kaggle competitions or similar data science challenges to hone your practical skills.
  • Taking online courses or specialisations in emerging areas of AI/ML (e.g., Generative AI, Reinforcement Learning).

This is where the work is heading, and the higher pay with it. Get fluent here and the shift stops being a threat and starts being your edge.

Prompt Engineering & LLM Integration

Honestly, this is critical within the next 6 months—it's already happening, not just a future thing. Competitors are already using large language models (LLMs) to draft reports in 10 minutes that used to take 2 hours. Research Engineers who figure this out will outproduce their peers significantly.

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

Explainable AI (XAI) Techniques

Important within 12-18 months. As our models get more complex, stakeholders (and regulators) are increasingly demanding to know 'why' a model made a particular decision. Simply having high accuracy isn't enough anymore; we need to understand the underlying reasoning.

  • LIME & SHAP
  • Feature Importance Methods
  • Causal Inference Basics
  • Counterfactual Explanations

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, a lot of a Research Engineer's time is spent on repetitive tasks, sifting through papers, or writing boilerplate code. We're not just talking about the future; AI is already here to help you get more done, faster. Think of it as having a highly efficient assistant for your most tedious work.

Our R&D team is actively integrating AI-powered tools to streamline the research process. This means you won't just be building AI models; you'll be using AI to build them more effectively. We want you focusing on the truly novel, challenging parts of research, not getting bogged down in the mundane. Here's how AI can transform your day-to-day as a Research Engineer:

Automated Hyperparameter Sweeps

Instead of manually tracking hundreds of model runs and trying to figure out the best settings, you'll use tools like Weights & Biases Sweeps or Optuna. These integrate with an LLM to intelligently search for optimal model parameters, automatically generating reports on the best-performing configurations. This means less spreadsheet wrangling and more actual research.

AI-Powered Literature Review

Gone are the days of endlessly clicking through arXiv. You'll use AI research assistants (like Elicit or Scispace) to feed in a core paper and have it instantly find, summarise, and categorise 20 related works. It'll even highlight contradictory findings or subtle methodology differences, giving you a massive head start on understanding a new domain.

Copilot for Prototyping

Imagine having an expert pair programmer at your side, always. Tools like GitHub Copilot will write boilerplate code for data loading, pre-processing, visualisation, and model scaffolding. This frees you up to focus on the truly novel parts of the algorithm and the unique research questions, rather than getting stuck on repetitive setup code.

Documentation & Update Generation

After an experiment sprint, you can feed your raw technical notes, code snippets, and W&B charts into an LLM. It'll churn out a first draft of a Confluence update page, a progress summary for stakeholders, or even the methods section for a patent application. This massively reduces the time spent on administrative tasks, letting you get back to the fun stuff.
