Developer - Quantitative Hedge Fund

About the role

My client, a quantitative hedge fund, is seeking a Developer in Testing to join their London-based Technology team. The successful individual will have ownership of technical products and projects for the firm's trading platform, ensuring every release is safe and efficient. This is not a traditional QA role – you will be engineering automated solutions to prevent issues, not simply identifying them.

Working closely with Quants and Developers, you will have genuine autonomy to shape the firm's testing strategy, build bespoke test harnesses, and enhance CI/CD pipelines to push the boundaries of what automated testing can achieve.

The team is shifting from operational work toward strategic, ground‑up development – including supporting the build‑out of new trading entities – so this is an excellent opportunity for someone looking to drive meaningful change rather than maintain the status quo.

• Extensive experience in C#/.NET, Java, or Python
• Experience building and enhancing CI/CD pipelines and automated test frameworks
• The confidence to manage stakeholder expectations and communicate technical risk to non-technical audiences
• A pragmatic, results‑oriented mindset that prioritises business value over theoretical perfection

My client is open on compensation and will pay what is required to secure the right person. In addition, they offer a highly competitive benefits package including private healthcare, an on‑site gym, and breakfast and lunch daily.
