* Design, build, and maintain high-performance exchange connectivity for orders and market data across multiple venues
* Work on connectivity to novel liquidity access platforms, such as intent-based venues
* Deliver robust, observable services with clear SLAs and graceful failure modes
* Optimize latency, throughput, and stability in production environments
* Collaborate with traders, quants, and product teams to translate strategy needs into reliable systems
* Establish strong testing, simulation, and replay workflows for fast and safe iteration
* Champion code quality, observability, incident response, and performance profiling, embedding security at every stage
* Help shape technical standards and mentor teammates in a high-caliber engineering group
Background and Experience
* 3+ years of hands-on experience in Rust and/or C++ in production
* Experience in modern C++ is a plus, especially for systems-level or low-latency work
* Proven track record in building exchange connectivity: order entry APIs, lifecycle management, market data handling, parsing, normalization, and distribution

* Experience with FIX, WebSocket, gRPC, REST, custom binary protocols, or feed handlers
* Knowledge of CI/CD for high-availability systems and a DevSecFinOps approach in the cloud
* Experience with time-series data, event sourcing, and deterministic replays
* Genuine passion for and deep interest in digital assets and crypto trading
How We Work
* Impact-driven: small, experienced team with high ownership and short feedback loops
* Production-first: rigorous testing, staged rollouts, and observability baked in
* Partnership with trading: rapid iteration with tight alignment to strategy needs
* Quality mindset: code reviews, benchmarks, and a post-incident learning culture
Location and setup
* Full-time role within Keyrock’s StratMM BU
* Remote-first, hybrid-friendly, with close collaboration across engineering and trading
