7Would you like it

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

What people enjoy
Building Tangible Things

You get a real buzz from seeing your code go live and knowing it's making a difference. You're not content with just theoretical models; you want to see them in action, solving real problems for real users.

The satisfaction of seeing your new recommendation model increase click-through rates by 10% on the live website.

Solving Technical Puzzles

You love the challenge of figuring out why a model isn't performing as expected, or optimising a slow data pipeline. Complex technical problems feel less like a chore and more like an exciting puzzle to crack.

Spending an afternoon debugging a tricky Docker build issue, then finally getting it to work and understanding the root cause.

Continuous Learning & Growth

You're always keen to pick up new frameworks, read the latest research papers, or dive into a new cloud service. You see every challenge as an opportunity to expand your skillset and become a better engineer.

Voluntarily signing up for an online course on advanced PyTorch techniques or spending your lunch break experimenting with a new MLOps tool.

What frustrates people
  • The Data Swamp: Honestly, you'll spend more time cleaning, transforming, and understanding messy, undocumented data than actually building models. It's often 60% data wrangling, 40% everything else. If you hate that, it'll be a grind.
  • The 'AI Magic Wand' Fallacy: You'll constantly be asked to 'just sprinkle some AI' on business problems that are fundamentally broken or lack the necessary data. Managing those expectations and explaining limitations can be exhausting.
  • Production vs. Notebook Dichotomy: A model that looks brilliant in your Jupyter notebook can fall apart in production due to subtle data shifts, latency issues, or edge cases you never trained for. Getting it to work reliably in the real world is a different beast.
  • Justifying the Cloud Bill: You won't directly manage the budget, but you'll certainly feel the pressure to write efficient code and use cloud resources wisely. You might be asked to explain why your training job needed that expensive GPU instance.
  • Moving Goalposts: Business requirements and definitions of 'success' can change mid-project, meaning you might have to re-architect parts of your solution. It's frustrating, but it's part of working in a dynamic environment.
What this role does not give you
  • Direct people management responsibilities (that comes later).
  • A purely research-focused role; this is about applied ML.
  • A static, predictable environment where requirements never change.
  • A guarantee that every model you build will make it to production (sometimes business priorities shift).

8Who you work with

Your work directly improves the intelligence of our products and internal tools. Get it right, and we're faster, smarter, and our customers are happier. Get it wrong, and we risk making poor automated decisions or creating frustrating user experiences. You're a core part of turning data into real business value.

Inside the business
  • Senior AI/ML Engineers (your go-to for technical questions)
  • Product Managers (who define what we're building)
  • Data Engineers (who look after the data pipelines)
  • Software Engineers (who integrate our models into applications)
  • QA/Testing Teams (who help us catch bugs)
Outside the business
  • None directly, but your work impacts our customers daily.

9What you need before you start

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

  • Proven ability to independently build, train, and deploy at least 2-3 machine learning models into a production environment.
  • Demonstrable experience with Python and its key ML libraries (PyTorch/TensorFlow, scikit-learn, pandas, NumPy).
  • Solid understanding of software engineering best practices, including version control (Git), testing, and code review.
  • Experience working with cloud platforms, specifically AWS, for ML workloads.
  • A track record of clear, concise technical communication, both written and verbal.

10What to practise next

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

Optimising ML Workloads for Cost & Performance

As our cloud spend grows, understanding how to get the most bang for our buck is critical. This means not just building models, but building them efficiently and cost-effectively.

Instance Type Selection · Spot Instances & Managed Spot Training · Model Quantisation & Pruning · Data Partitioning & Storage Optimisation

  • This week: Review the AWS billing dashboard for your team's services. Identify the biggest cost drivers.
  • This month: Experiment with running one of your training jobs on a spot instance or a different instance type. Document the cost and performance impact.
  • Month 2: Research model optimisation techniques like quantisation. Can you apply it to a small model you've built?
  • Month 3: Present a brief overview of cost-saving strategies for ML workloads to your team.

Quick win: Always consider the smallest effective instance type for your development and testing. Use managed services where possible to offload operational overhead.

Distributed Training & Large-Scale Data Processing

Our datasets are only getting bigger, and some models are becoming too large to train on a single machine. You'll need to understand how to scale your work across multiple machines efficiently.

Distributed Data Processing Frameworks · Data Parallelism & Model Parallelism · Fault Tolerance in Distributed Systems · Cluster Management (Kubernetes/SageMaker Distributed)

  • This week: Read up on the basics of distributed training in PyTorch or TensorFlow.
  • This month: Try to refactor a local data processing script to use PySpark on a small Databricks cluster.
  • Month 2: Participate in a project that involves distributed model training, even if it's just observing and asking questions.
  • Month 3: Take an online course or tutorial on a distributed computing framework like Spark.

Quick win: Start thinking about the 'scale' of your data from day one. Ask yourself: 'What happens if this dataset is 100x bigger?'

11Staying current once you are in

What people here do to keep up
  • Actively participate in ML engineering communities (online forums, local meetups).
  • Contribute to open-source ML projects, even small bug fixes or documentation improvements.
  • Attend relevant industry conferences or workshops (e.g., PyData, KubeCon, AWS re:Invent).
  • Regularly read and critically evaluate new research papers from arXiv or leading ML conferences.
  • Take advanced online courses on MLOps, distributed systems, or specialised ML domains.

What's rising in its place

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

Large Language Models (LLMs) are everywhere, and they're changing how we interact with data and build applications. Competitors are already using these to automate tasks that used to take hours. Engineers who can effectively 'talk' to LLMs and integrate them into our systems will be massively more productive.

  • Context Windows & Token Limits
  • Temperature & Top-P Sampling
  • Retrieval Augmented Generation (RAG)
  • Output Validation & Hallucination Detection
  • Prompt Chaining & Agentic Workflows

Advanced MLOps Practices (Practical Application)

As our model portfolio grows, we need to get smarter about how we manage the entire ML lifecycle. Manual processes won't scale. Automating more of the training, deployment, and monitoring will be crucial for efficiency and reliability.

  • CI/CD for ML Pipelines
  • Feature Stores (Usage & Contribution)
  • Model Monitoring & Alerting
  • Experiment Tracking & Reproducibility
  • Infrastructure as Code (IaC) for ML

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be honest, a lot of an AI/ML Engineer's day can be taken up with repetitive tasks. But what if you could offload some of that grunt work to AI? We're not talking about replacing you, but giving you a superpower. Our team actively uses AI-powered tools to make our lives easier, letting us focus on the really interesting, complex problems.

Imagine spending less time on boilerplate code, debugging, or sifting through endless research papers. That's the reality for our AI/ML Engineers. We're integrating smart assistants into our workflow to automate the tedious bits, giving you back precious hours every week. Here's a glimpse of how you'll use AI to be more productive:

Code Automation & Debugging

Use tools like GitHub Copilot to auto-complete boilerplate code, suggest function implementations, and even help you debug tricky issues by explaining error messages or suggesting fixes. It's like having a pair programmer who never sleeps.

Data Exploration Assistant

Feed your messy datasets into an LLM-powered tool to get instant summaries, identify outliers, suggest feature engineering ideas, or even generate initial visualisations. This cuts down hours of manual exploration, letting you get to insights faster.

Research Paper Summariser

Instead of slogging through dozens of academic papers, use AI to summarise the key findings, methodologies, and potential applications of new research. Quickly identify the most relevant papers for your current project and stay on top of the latest advancements without the heavy lifting.

Technical Documentation Drafter

Generate first drafts of model cards, API documentation, or internal wiki pages from your code comments or even verbal descriptions. You'll then refine and add the critical human context, but the initial structure and content are already there, saving you loads of time.
