The company
This specialist digital-asset house has spent the past decade building the rails that link professional investors to crypto markets. Three core businesses power the firm:

  • Actively managed hedge-fund strategies – run by veteran traders who deploy dynamic, market-beating tactics for institutional clients.
  • Multi-asset indices – transparent benchmarks that bridge traditional and digital assets, covering equities, crypto and even gold.
  • Capital-markets & treasury desk – a front-office team that designs low-latency trading tech, manages group liquidity and provides execution services to every business line.

With revenues climbing, they have an unmissable opportunity for a hands-on Lead Engineer to own green-field builds on the trading floor.

What you will get
Real front-office exposure to FX, equities, commodities and crypto flow; 70% hands-on coding in Python 3.12 and Go 1.22; occasional C++ / Java where latency demands. Exchange-connectivity challenges at scale – order routing, market-data ingestion, venue gateways. Direct route to Head of Engineering as the platform grows. High-velocity delivery culture: decisions in minutes, releases in days, not quarters. Top-tier comp: base, bonus and full benefits.

What you will do
Architect and deliver low-latency market-data and execution services from scratch. Stay deeply technical while mentoring a small squad of engineers. Embed with traders to iterate quickly on new features and strategies. Drive best practice in test automation, observability and secure coding.

What you will need
Proven front-office or buy-side background in FX, equities, commodities or crypto. Expert-level Python and/or Go; comfortable switching from C++ or Java. Track record shipping exchange-connectivity or execution-flow systems. β€œGet-it-done” mindset – able to cut through blockers and hit aggressive deadlines. Leadership experience: coaching devs, owning architecture and the full SDLC. Happy to work in London 5 days a week.
