Senior Quant Developer (Python) - Systematic Trading in Slough

The Opportunity

Tempest Vane Partners is working exclusively with a top-tier systematic macro hedge fund – one of Europe’s most respected names in the space – to find an exceptional Quantitative Developer for their London-based Alpha Technology team. The mandate here is clear: you will own technology that is woven directly into the fabric of live trading. No handoffs to a middle layer. No waiting six months to see your work in production. The strategies you support are running today, and the tools you build will shape how they run tomorrow.

If you’ve spent years building serious systems but feel the distance between your keyboard and a real trading decision is growing wider, this is the role that closes it.

What Sets This Apart

• You will work at the intersection of cutting-edge systematic strategy and production engineering, a rare combination even at the most sophisticated firms.
• Direct, day-to-day collaboration with portfolio managers and traders who will use and challenge what you build.
• Full lifecycle ownership: from whiteboard to back-test to live deployment, the work is yours.
• A lean, high-trust culture where merit travels fast and bureaucracy doesn’t.
• A modern cloud-native infrastructure stack and you’ll be building forward, not maintaining the past.

The Role

You’ll be a core member of a team that keeps systematic strategies running, evolving, and performing. That means:

• Designing and delivering Python-based tooling across the entire trading strategy lifecycle, from early-stage research infrastructure through to operational, production-grade systems.
• Engaging directly with quantitative researchers and traders to translate complex requirements into elegant, robust solutions.
• Taking genuine ownership of systems that carry real commercial weight; latency, reliability, and correctness all matter here.
• Contributing to a cloud-first technology environment, with hands-on exposure to distributed systems, containerisation, and modern data infrastructure.
• Bringing both the technical rigour and the communication skills to work across disciplines without losing either.

What You Bring

This firm doesn’t hire generically. They’re looking for someone who is technically formidable, intellectually curious, and comfortable operating with a high degree of autonomy. Specifically:

• A decade or more of professional software engineering experience, with Python at the centre of your craft.
• Deep fluency in quantitative and data-heavy development; you know your way around numerical libraries and you write code that others can trust.
• Commercial proficiency in at least one systems-level language, C#, Java, or C++.
• A track record in systematic trading or quantitative finance; you understand the domain, not just the tools.
• Solid grounding in database technologies and distributed messaging systems.
• Experience with cloud infrastructure, AWS in particular and modern DevOps tooling.
• A degree in a rigorous quantitative discipline: Mathematics, Computer Science, Physics, Engineering, or equivalent.
• The kind of clarity and confidence that makes traders trust your work and quants want to collaborate with you.

Why Now, Why Here

The systematic macro space is not slowing down – and neither is this firm. They are actively investing in the technology layer that gives their strategies an edge, and this hire is part of that commitment.

Beyond the intellectual pull of the work, the firm offers:

• Compensation that reflects genuine market-leading performance: competitive base, significant bonus potential, and a strong pension.
• Private medical insurance and a comprehensive benefits package.
• On-site gym membership, a dedicated wellness facility, and complimentary daily meals. The kind of environment designed for sustained, high-performance.
• Real investment in your development: structured learning, exposure to world-class practitioners, and a clear path forward.

Who Should Apply

The strongest candidates will be those who find the boundary between quantitative research and production technology genuinely exciting. People who want to build things that matter, in an environment that rewards excellence without layers of process in the way.
