We are working with a pioneering financial technology firm that is building a global institution for digital assets, designed from the ground up for market integrity and efficiency. Their disciplined, first-principles approach underpins everything they do - from institutional liquidity provision and trading solutions to OTC execution and treasury management.
As part of their continued growth, they are seeking a Senior Exchange Connectivity Engineer to join their London office. This role sits at the heart of their trading infrastructure, focusing on ultra-reliable, low-latency integrations with major crypto exchanges.
Key Responsibilities

* Optimize order entry, market data ingestion, and account management for performance and reliability.
* Contribute to a fault-tolerant, scalable connectivity framework using Rust and Typescript.
* Collaborate with trading, infrastructure, and product teams to deliver high-quality integrations.
* Monitor, debug, and continuously improve production systems.
* Mentor junior engineers and help shape engineering best practices.
* Participate in on-call rotations and occasional travel as needed.
Ideal Candidate Profile
* 3-5+ years of professional software engineering experience.
* Minimum 1 year of hands-on experience integrating with crypto exchanges.
* Strong understanding of networking fundamentals (HTTP, WebSocket, TCP, TLS).
* Proficiency in Rust or a strong C++ background with exposure to Rust.
* Working knowledge of Typescript.
Nice to Have
* Experience with Web3 / DeFi protocols.
* Leadership or mentoring experience.
* Familiarity with traditional finance connectivity protocols (ITCH / OUCH / UDP Multicast).
This is a unique opportunity to join a high-impact team shaping the future of digital asset infrastructure. If you're passionate about building robust systems and thrive in a fast-paced, collaborative environment, we'd love to hear from you.
