Location: 100% Remote
Compensation: Up to 500,000 EUR total compensation
Type: Full-time
About the Role
We are seeking a highly skilled C++ Engineer to join a small, elite team working at the intersection of low-latency infrastructure and centralized crypto finance (CeFi). In this role, you will take ownership of exchange connectivity, building and optimizing critical paths that power trading strategies across a variety of major centralized exchanges.
This position is ideal for engineers who thrive in performance-critical environments and want to build systems that directly impact trading outcomes. You''ll work in a collaborative, engineering-first environment with minimal bureaucracy and a strong emphasis on autonomy and results.
Responsibilities
- Design, implement, and maintain low-latency C++ systems to connect with CeFi exchanges.
- Develop robust order entry and market data pipelines for major crypto exchanges (REST, WebSocket, FIX, proprietary protocols).
- Profile, benchmark, and tune code for optimal performance under production conditions.
- Interface directly with exchanges to troubleshoot connectivity issues, onboard new venues, and adapt to evolving APIs.
- Work closely with strategy developers and infrastructure teams to support trading needs in real-time.
Requirements
- 2+ years of professional C++ experience, ideally in a high-frequency or low-latency trading environment.
- Strong command of modern C++ (C++17 or newer), with a focus on performance, memory management, and concurrency.
- Experience working on exchange gateways, market data handlers, or order routing infrastructure.
- Solid understanding of networking (TCP/UDP, WebSockets, FIX) and multithreaded programming.
- Excellent debugging, profiling, and system-level troubleshooting skills.
- Self-driven, with the ability to operate independently in a fast-paced environment.
Nice to Have
- Familiarity with crypto exchanges and their API ecosystems (Binance, Coinbase, OKX, etc.).
- Exposure to exchange connectivity protocols in traditional finance or crypto (FIX, ITCH, OUCH).
- Experience working in distributed systems or event-driven architectures.
- Background in systems programming or performance engineering.
Why Join
- Competitive compensation: up to 500,000 EUR total package - based on experience.
- Remote-first setup with flexible hours.
- Opportunity to work on cutting-edge trading infrastructure with real-world impact.
- High ownership, low bureaucracy environment tailored for top-tier engineers.
