Senior Full Stack Engineer | Trading Systems & Real-Time UI

Most full stack engineers have never had a trader lean over their shoulder and ask why a position update took half a second. If you have, this role is likely relevant to you.

I am working on a confidential mandate for a London-based trading firm rebuilding its client-facing trading platform from the ground up.

They are looking for a senior full stack engineer who understands that the frontend of a trading application is not a website. It is a mission-critical instrument used in live market conditions.

The environment is highly engineering-led and focused on performance, responsiveness, and reliability under real-time trading workloads.

The stack includes:

• C# focused frontend engineering
• WPF and/or Blazor
• Real-time UI development for traders and execution teams
• React or Angular across broader platform and API interaction layers
• Streaming market data, order flow, position management, and concurrent event-driven systems

This is not a generic enterprise engineering role.

The users are professional traders operating in fast-moving market environments. They think in ticks, liquidity, and execution quality — not page load times.

The team itself includes engineers from leading trading firms, systematic funds, HFT environments, and tier-one investment banks. The expectation around engineering quality, system design, and responsiveness is exceptionally high.

Trading desk experience is not a “nice to have” here. It is central to the mandate.

If you have built production-grade C# trading applications and understand what it means to engineer software directly for front-office users, I would genuinely like to speak with you.

The role is confidential and off-market. Compensation reflects the seniority and rarity of the profile being sought.

DM me directly or email me for additional information. Full details available under NDA.
