You know that job where you quietly validate models in a dusty corner of the risk department?

Yeah. This isn’t that job.

This is leading a team that challenges the models that decide who gets credit, who’s flagged as fraud, and how millions in provisions are set aside. It’s a job where the wrong call has real consequences - and the right one keeps the business out of the headlines.

You're not here to say yes.

You're here to ask: “Are you sure?”

And sometimes: “What the hell were you thinking?”

What you’ll actually be doing:

  • Leading the Model Risk and Validation function in a fast-paced financial environment.
  • Building frameworks that regulators respect and internal teams can actually follow.
  • Validating complex models - credit risk, fraud, IFRS9 - all the fun stuff.
  • Digging into assumptions, code, data, and logic. No surface-level reviews.
  • Building a team of people who know how to challenge without being obnoxious.
  • Dealing with senior stakeholders who don’t want “it depends” as an answer.
  • Explaining technical complexity to people who stopped caring after the third slide.
  • Staying just ahead of regulatory changes, without making them your entire personality.

What we need from you:

  • You’ve led a team. A real one. Not just an intern and a weekly stand-up.
  • 7+ years deep in model risk, validation, or building the things yourself. Ideally in the Financial Services sector.
  • You can code. Python. SQL. Bonus points if you’ve wrestled with messy production code.
  • You’ve had conversations with regulators that didn’t end in panic or confusion.
  • You can say, “This model’s wrong and here’s why,” without writing a 40-page slide deck.
  • You know when to be technical, when to be strategic, and when to shut up and listen.
  • A proper degree in something terrifying would be great - stats, maths, data science, whatever.

Why this role?

Because it’s rare to find a role where the business wants to be challenged - and will give you the space, the backing, and the budget to do it properly.

No fluff. No layers of red tape. Just a leadership role that actually leads.

If that sounds more interesting than another year spent tweaking someone else’s model, hit apply.

Or don’t. Just don’t complain when someone else does.

How Many Machine Learning Tools Do You Need to Know to Get a Machine Learning Job?

Machine learning is one of the most exciting and rapidly growing areas of tech. But for job seekers it can also feel like a maze of tools, frameworks and platforms. One job advert wants TensorFlow and Keras. Another mentions PyTorch, scikit-learn and Spark. A third lists Mlflow, Docker, Kubernetes and more. With so many names out there, it’s easy to fall into the trap of thinking you must learn everything just to be competitive. Here’s the honest truth most machine learning hiring managers won’t say out loud: 👉 They don’t hire you because you know every tool. They hire you because you can solve real problems with the tools you know. Tools are important — no doubt — but context, judgement and outcomes matter far more. So how many machine learning tools do you actually need to know to get a job? For most job seekers, the real number is far smaller than you think — and more logically grouped. This guide breaks down exactly what employers expect, which tools are core, which are role-specific, and how to structure your learning for real career results.

You must send clear signals of relevance, delivery, impact, reasoning and readiness for production — and do it within the first few lines of your CV or portfolio.
