Working for a globally renowned financial organisation

Your new role

We are hiring two Senior Data Engineers to support the ongoing development and modernisation of a large‑scale financial data platform. The environment blends long‑established enterprise systems and legacy components with modern cloud services hosted on AWS. The platform processes high‑volume structured datasets and powers a mix of internal business systems and customer‑facing financial products.

A major part of the estate consists of large SQL Server environments; therefore, advanced SQL Server expertise is essential. You will take a leading role in modernising core components, improving platform performance and resilience, and building scalable backend and data services as the platform evolves.

This role suits engineers who are confident working across legacy and modern stacks, and who bring strong experience in programming/ designing and delivering robust data services and APIs.

What you'll need to succeed

Expert‑level SQL Server development and optimisation experience.

Experience working in environments with significant legacy components.

Strong AWS knowledge (Lambda, Amazon S3, API Gateway; certifications beneficial).

Experienced with programming languages such as Python or C#.

Background in financial services or data‑heavy platforms with experience with legacy/ modern platforms.

Solid mathematical or quantitative background would be beneficial for analytics‑focused work.

What you'll get in return

Flexible working options available.

Where to Advertise Machine Learning Jobs in the UK (2026 Guide)

Advertising machine learning jobs in the UK requires a different approach to most technical hiring. The candidate pool is small, highly specialised and in demand across AI labs, financial services, healthcare, autonomous systems and consumer technology simultaneously. Machine learning engineers and researchers move between roles through professional networks, conference communities and specialist platforms — not general job boards where ML roles compete with unrelated software engineering positions for the same audience. This guide, published by MachineLearningJobs.co.uk, covers where to advertise machine learning roles in the UK in 2026, how the main platforms compare, what employers should expect to pay, and what the data says about hiring across different role types.

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.
