Overview

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 include:

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.

Requirements

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.

What’s on Offer

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
Great bonus and equity potential
