Job description

Founding Back-End Engineer3>

London

Join a high-growth fintech startup transforming global markets. Our client is an early-stage, well-funded fintech venture building a next-generation trading platform that brings 24/7 access, advanced leverage, and cutting‑edge performance to traditional financial assets.

Backed by top-tier Silicon Valley investors, they’re reimagining how modern markets should operate — and they’re looking for a founding engineer to shape the core architecture from day one.

This is a rare chance to join a technical founding team with backgrounds in quant trading, HFT, and world-leading financial institutions. You’ll work on real‑time systems where microseconds matter, write software that must never go down, and set the engineering standards that future hires will inherit.

If you want to build something truly category‑defining — this is it.

What You’ll Need

• Proven experience with high-performance languages (Rust, C, C++)
• 3+ years working on real-time trading systems, exchanges, or HFT platforms
• Ideally a strong STEM degree from a top-ranked university (or equivalent academic excellence)

Bonus Points

• Fintech, exchange, or low‑latency engineering experience
• Expertise with Rust
• Deep knowledge of Kubernetes, infrastructure‑as‑code, or distributed systems
