We are partnered with a leading fixed income hedge fund in London seeking a talented C# Developer to join their front-office technology team. The fund has a strong and consistent performance track record and has invested heavily in its quant and tech capabilities as part of a wider growth plan. You’ll work closely with the quant team as well as traders and other front office stakeholders to build and enhance core trading systems, research tooling, and data-driven applications. Projects span proprietary trading system development, front-office tools, and the application of machine learning across the investment process. The environment is fast-paced, collaborative, and a highly technical one where code quality and low latent systems are a top priority. This team has a history of developing people’s careers and offers a broad and exciting range of new and existing projects for hires to get stuck into. These will consist of both back-end and front-end projects with 1 week sprints and release cycles, PR review processes and continuous development to master.

The CTO is particularly interested in candidates that are passionate about technology and want to grow and learn within a fast paced and highly performant environment. You’ll have direct exposure to PMs, quants, and the CTO, and will contribute across design, architecture, and production support. Requirements: • Strong academic background in Computer Science or related field, • Excellent programming skills in C# and .Net, • Experience working with large data sets, • 1–5 years’ experience in a relevant software engineering role, • Interest in finance; fixed income or systematic experience a plus, • Positive, pragmatic, and collaborative mindset This is a rare opportunity to join a high-performing, technology-driven hedge fund with a genuinely collegiate culture.
