Role Purpose & Context

Role Summary

The Senior AI/ML Engineer is responsible for leading the technical design and delivery of complete machine learning projects, from initial concept right through to deployment and monitoring. You'll translate complex business problems into concrete ML solutions, making sure they're robust and actually deliver value. You'll work at the intersection of data science, software engineering, and business strategy, turning raw data and vague requirements into powerful predictive models that our internal teams and customers rely on. When this role is done well, our AI products are reliable, accurate, and genuinely impact our bottom line, perhaps by reducing operational costs or unlocking new revenue streams. When it's not, we end up with models that are either too slow, too inaccurate, or simply don't solve the real problem, which can cost us a lot of time and money. The challenge is often balancing technical perfection with business pragmatism, especially when dealing with messy data or shifting priorities. The reward, honestly, is seeing your models go live and knowing they're making a real difference, plus the chance to mentor some bright junior engineers along the way.

  6. Daily: The rapid pace of AI/ML doesn't scare you; it energises you. You're always keen to pick up new frameworks, understand the latest research, and apply cutting-edge techniques. You see every challenge as an opportunity to expand your skillset.

Potential Demotivators

Honestly, this job isn't always glamorous. You'll spend a fair bit of time wrestling with messy, undocumented data from legacy systems—probably 70% of your time, if we're being real. You'll also deal with stakeholders who think AI is a magic wand and expect a 'ChatGPT for our business' without understanding the data or infrastructure needed. The model that worked perfectly in your Jupyter notebook might completely fall apart in production due to data inconsistencies or scaling issues, which is incredibly frustrating. You'll probably find yourself fighting with other teams for access to limited GPU resources, meaning late-night training runs. And yes, business requirements will change halfway through a project, invalidating weeks of your work. If you need every piece of work to make it to production, or if you can't handle the constant flux and occasional dead ends, you'll probably struggle here.

Common Frustrations

  1. The 'Garbage In, Garbage Out' reality: spending most of your time cleaning and joining messy, undocumented data.
  2. The 'AI Magic Wand' expectation: stakeholders asking for impossible things without understanding the technical debt.
  3. The Dev-to-Prod Chasm: models working perfectly in dev but failing spectacularly in production.
  4. Fighting for GPU time: competing for limited compute resources, often leading to awkward scheduling.
  5. The Moving Goalposts: business requirements changing mid-project, rendering previous work obsolete.
  6. Justifying existence: constantly having to prove the ROI of ML projects that have long lead times.
  7. Hype Cycle Whiplash: being forced to drop promising projects to chase the latest, often unproven, trend.

What Role Doesn't Offer

  1. A perfectly clean, pre-processed dataset handed to you daily.
  2. A predictable, unchanging set of requirements for every project.
  3. Unlimited compute resources available at your whim.
  4. Immediate, guaranteed production deployment for every model you build.
  5. A quiet, isolated environment where you only interact with code.

ADHD Positives

  1. The fast-paced nature of ML research and problem-solving can be highly engaging for those with ADHD, offering constant novelty and intellectual stimulation.
  2. The need to quickly pivot between different technical challenges (e.g., debugging a model, optimising a pipeline, researching a new algorithm) can align well with a preference for varied tasks.
  3. Hyperfocus can be a superpower when deep-diving into complex codebases or optimising model performance.

ADHD Challenges and Accommodations

  1. The extensive documentation and meticulous data cleaning aspects might be challenging; we can use AI tools to automate some of this and provide clear templates.
  2. Managing multiple ongoing projects and shifting priorities can be tough; we use agile methodologies with clear sprint goals and daily stand-ups to help maintain focus.
  3. We can offer noise-cancelling headphones for deep work and flexible work arrangements to help manage energy levels.

Dyslexia Positives

  1. Strong spatial reasoning skills, often found in dyslexic individuals, are incredibly valuable for understanding complex system architectures and data flow.
  2. Excellent problem-solving abilities and 'big picture' thinking can help in designing innovative ML solutions.
  3. The visual nature of data exploration, model visualisations, and MLOps dashboards can be very intuitive.

Dyslexia Challenges and Accommodations

  1. Extensive reading of technical documentation or research papers can be demanding; we encourage the use of text-to-speech tools and AI summarisation.
  2. Writing clear, concise code and documentation is crucial; we support tools like Grammarly, GitHub Copilot for code comments, and peer review processes for all written output.
  3. We ensure all internal tools and platforms are compatible with assistive technologies and offer flexible formatting for documents.

Autism Positives

  1. A strong preference for logical, systematic thinking aligns perfectly with the structured nature of engineering and ML model development.
  2. Attention to detail and a knack for pattern recognition are invaluable for identifying subtle bugs, data anomalies, or model drift.
  3. The ability to focus intensely on complex technical problems for extended periods can lead to deep insights and robust solutions.

Autism Challenges and Accommodations

  1. Navigating ambiguous requirements or rapidly changing priorities can be difficult; we strive for clear, written communication and provide structured processes for change management.
  2. Social interactions, especially in cross-functional meetings, can be draining; we support asynchronous communication where possible and provide clear agendas and pre-reads for meetings.
  3. We offer quiet workspaces, flexible working hours, and a clear understanding of communication preferences to minimise sensory overload and social fatigue.

Sensory Considerations

Our office environment is typically open-plan with some dedicated quiet zones. Expect moderate background noise during core working hours, though we encourage the use of headphones for focused work. We use standard office lighting. Social interactions are generally collaborative and project-focused, with regular team meetings and informal discussions. We're happy to discuss specific needs to make sure you're comfortable.

Flexibility Notes

We believe in flexibility where it makes sense. We offer hybrid working, usually a few days in the office and a few from home, but we're always open to discussing arrangements that best support your productivity and well-being. The key is delivering great work, not clocking specific hours.

Key Responsibilities

Experience Levels Responsibilities

  1. Level: Senior AI/ML Engineer (L3)
  2. Responsibilities: Lead the technical design and implementation of end-to-end ML projects, from data exploration and feature engineering through to model training, evaluation, and deployment. This means you'll own the technical roadmap for a specific ML solution.
  3. Design and build robust, scalable MLOps pipelines using tools like `Kubeflow` or `Airflow` to automate model training, testing, and deployment. Frankly, if it's not automated, it's not production-ready.
