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.
