Design, build, and operate low-latency C++ services for real-time market-data ingestion, normalization, price indexing, and trading infrastructure. Optimize Linux systems for latency, throughput, memory use, and reliability; develop off-chain and on-chain integrations; improve observability; and own services through deployment and production operations. Collaborate with protocol, trading, and infrastructure teams while maintaining rigorous testing, documentation, and code quality.
We are building the low-latency engine that powers 150+ price indexes and delivers a ~10ms index heartbeat. As a Senior C++ Protocol Engineer on Core Infrastructure, you will design and operate the systems that ingest, normalize, and distribute real-time market data across our platform.
You will work at the intersection of high-performance systems engineering, market data, and blockchain infrastructure. This is a hands-on role for an engineer who enjoys owning performance-critical services end to end—from architecture and implementation through profiling, deployment, and production reliability.
What You’ll Do
- Design, build, and operate low-latency C++ services for price indexing, market-data processing, and trading infrastructure.
- Ingest real-time market data from multiple venues and normalize it into consistent, reliable internal formats.
- Build and maintain the pipeline that publishes price indexes with tight latency and accuracy requirements.
- Profile systems on Linux and optimize for latency, throughput, memory use, and resilience under high message volume.
- Develop components that bridge off-chain systems with on-chain protocols and smart-contract-facing infrastructure.
- Improve observability through metrics, tracing, alerting, and production-grade monitoring.
- Set a high bar for code quality through rigorous testing, code review, documentation, and operational ownership.
- Partner with protocol, trading, and infrastructure teams to turn product and reliability requirements into robust systems.
What We’re Looking For
- 5+ years of professional experience with modern C++, ideally C++17 or C++20.
- Experience building low-latency, high-throughput, or high-frequency systems.
- Strong command of multithreading, concurrency, lock-free or low-contention patterns, memory management, and networking.
- Deep familiarity with Linux performance tooling, profiling, tuning, and production debugging.
- Excellent understanding of data structures, algorithms, distributed-system fundamentals, and system design.
- Experience designing services where correctness, availability, and latency are first-class requirements.
- Strong communication skills and comfort owning complex systems in a fast-moving environment.
Nice to Have
- Background in HFT, exchanges, market-data infrastructure, or financial systems.
- Experience with blockchain clients, node infrastructure, or protocol-level development.
- Familiarity with Rust, especially for performance-critical or systems-level components.
- Experience with message queues, time-series data, market-data feeds, or real-time analytics.
- Contributions to open-source infrastructure, networking, or performance-engineering projects.
