Senior Exchange Connectivity Engineer | Crypto

Job description

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

• Design and implement exchange connectivity modules (REST, WebSocket, FIX, proprietary APIs).
• 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.
