Job Description
Quantitative Developer - Systematic Trading (London)
A leading systematic investment firm, managing over $6 billion in assets, is spinning out from the quantitative division of a globally recognized hedge fund to become an independent investment firm. This is a rare opportunity to join during a major growth phase and help build the firm's long-term technology platform.

What the work covers:

• Designing and operating systems that deliver real-time market data to trading infrastructure, where speed and reliability are fundamental requirements
• Building integrated environments where quantitative researchers develop, test, and deploy predictive models - from feature engineering through execution
• Architecting cloud-based simulation and experimentation platforms that support large-scale quantitative research without becoming a bottleneck
• Standing up toolchains for new asset classes or trading strategies - the kind of foundational work where you're defining what needs to exist
• Working across boundary of research and production - ensuring that what quants build in notebooks can actually run reliably at scale

The technology is primarily Python, with C++ where performance demands it. The infrastructure runs across both on-premises systems and cloud. ML is used as one tool among many - this is a systematic shop, not an AI-first fund.
 
Qualifications

• Bachelor's Degree in Computer Science, Mathematics, Statistics, or Operation Research only AND from a top 20 internationally ranked university
• You have real buy-side experience - or experience in an environment with similar standards. You've worked at a systematic fund, a quant trading firm, or you've transitioned from a top tech company and proven yourself in a trading environment. People from firms like the ones you'd expect are what they're looking for.  They are looking for people from top tech or quant companies, NOT Banks.
• You are a strong Python Engineer with good C++. 
• You have quantitative judgment. you need to understand how data, models, and trading systems interact. You can work productively with quants and understand what they need from the engineering side.
• You are senior enough to take ownership. CTO wants people he can hand large initiatives to and trust the output. 6 to 15+ years of relevant experience, with meaningful time in high-standards environments.
• Your communication skills are excellent - both written and verbal. The bar for this is genuinely high. If you can't articulate your thinking clearly, this isn't the right place for you regardless of your technical strength.
• You've achieved things. Years of experience is not the only metric - for example 5 years out of Oxford and already operating at a level most people reach at 12, this is the level we are seeking.

Why is This a Great Opportunity:
The firm already has the capital, the leadership, the talent, and the track record. What makes this moment special is that the spin-out has not completed yet. The people joining now are building the independent platform from the inside. Once the separation is done and the story becomes obvious to everyone, the best seats will be taken and the leverage will be different.
 
Base salary in London ranges from £120k - £160k+, but real number is total comp. Year 1 bonus is guaranteed, and for senior hires, total compensation ranges from £450k to well over £600k depending on experience and impact. The firm does not have rigid comp bands - if they see the value, they pay for it.
 
The London office is growing rapidly, with the firm recently expanding into additional space. Four days in-office, Mondays remote. 
 
Do not miss this once in a lifetime opportunity!
