Position: Algo Execution Software Quant Developer – Equities : $250-500k

Our client is an exciting, rapidly growing quantitative investment firm building a next-generation trading platform from the ground up. Backed by experienced portfolio managers and technologists, the fund is now live and trading, and is looking to add a high-calibre Execution Algorithms Developer to play a pivotal role in its continued growth.

This is a rare opportunity to join a lean, entrepreneurial environment where execution quality is mission-critical and where your work will have a direct and visible impact on P&L.

The Role

You will take ownership of the firm’s equity execution algorithms, contributing across the full lifecycle — from strategy design through to live deployment. Working closely with traders and quant researchers, you will help refine and scale a production execution platform already connected to prime brokers and actively trading.

Key Responsibilities

  • Develop, enhance, and maintain live equity execution algorithms in a production environment.
  • Own integrations with prime brokers and external execution venues.
  • Take algorithms from research through testing and into live trading.
  • Work directly with portfolio managers and quants to optimize execution performance.
  • Monitor live execution, analyse performance, and iterate rapidly in a startup setting.
  • Ensure robust, scalable, and well-controlled execution infrastructure.
  • Contribute to the evolution of the firm’s trading architecture as it grows.
Ideal Candidate Profile
  • Proven experience building and deploying equity execution algorithms that are live.
  • Hands-on experience connecting to prime brokers (FIX or equivalent).
  • Strong programming skills (Python, C++, Java, or similar).
  • Deep understanding of equity market microstructure and execution dynamics.
  • Comfortable operating in a small, fast-moving startup environment with high ownership.
  • Experience supporting live trading systems with real capital at risk.
Why This Opportunity Stands Out
  • Join a quant fund at an early stage, post-go-live, with strong momentum.
  • High visibility role with direct impact on trading outcomes.
  • Flat structure, minimal bureaucracy, and genuine technical ownership.
  • Competitive compensation with meaningful upside as the firm scales.
  • Huge backers - roadmap to $1billion AUM over next 18 months
