Job description

Full Stack Post Trade Developer – Elite Systematic Hedge Fund – C#, Angular/React, SQL – London – Market Leading Compensation

One of the world’s most forward-thinking systematic hedge funds is expanding its Post-Trade Technology group and is hiring a Post-Trade Developer to build the external-facing systems used by their global investors and stakeholders.

This team sits at the heart of the firm’s post-trade operations and works directly with Middle Office, Fund Accounting, Management Accounting, and Compliance. With a brand-new growth mandate in place, they are doubling the size of the team and bringing on multiple engineers.

If you enjoy full‑stack development, clean engineering, and building polished user‑facing tools for a highly sophisticated financial environment, this is a standout opportunity.

The Role

As a Client Solutions Developer, you will help build and maintain:

• Investor portals and external reporting platforms (think winton.com‑style portals)
• Client‑facing dashboards, visualisation tools, and bespoke reporting tools
• High‑quality UI components and micro‑apps used by investors, operations, and senior stakeholders

You’ll work closely with analysts, PMs, and developers in a lean, technically strong team where projects are shared and impact is visible.

• Frontend: Angular (React also fine)
• Database: SQL Server

What We’re Looking For

• Experience building client‑facing or external web applications
• Ability to collaborate closely with business teams
• Finance experience is a plus, but not required
• Academic backgrounds in Computer Science, Physics, Engineering, or similar are welcomed

Why This Role Is Unique

• Build front‑facing tools used by global investors
• Work across middle office, accounting, compliance, and tech
• Join a highly intelligent team with strong academic backgrounds
• Real ownership over products in a low‑bureaucracy environment

If you want a full‑stack role with real ownership, smart colleagues, and a modern technical environment, this is one of the top opportunities in London right now.
