Job Title: Golang Developer/Senior Golang Developer/ Lead Golang Developer Multiple openings Location: Chicago, Illinois (Initially Remote) Employment Type: Full Time Design and implement low-latency services in Go for trading infrastructure and market data processing. Build and optimize high-throughput data pipelines for real-time market data ingestion and order routing. Develop lock-free / wait-free data structures and concurrency primitives for performance-critical paths. Engineer systems with deterministic execution, minimizing latency variance and tail latency. Design and maintain distributed coordination systems using consensus protocols (Raft/Paxos) where required. Implement custom networking stacks or optimized RPC frameworks tailored for trading workloads. Work closely with Linux internals: Syscalls CPU pinning NUMA optimization Kernel bypass techniques (e.g., DPDK, Solarflare Onload) Optimize systems using: perf, eBPF, flame graphs Hardware counters and profiling tools Debug production systems under live trading conditions, ensuring stability and performance. Collaborate with quants and traders to align system behavior with strategy requirements. Required Qualifications 10+ years of experience in systems engineering or low-latency infrastructure 8+ years of production experience with Golang Strong understanding of: Concurrency and synchronization Memory models and allocation behavior High-performance system design Experience building real-time or low-latency systems (trading, networking, or similar domains) Hands-on expertise with: Lock-free programming Atomic operations Multithreaded system design Strong knowledge of: Linux internals and performance tuning Networking (TCP/UDP, multicast, low-latency pipelines) Experience with profiling and debugging tools Exposure to high-frequency trading systems or market microstructure Experience with: Kernel bypass networking (DPDK, Solarflare) RDMA / high-speed networking Familiarity with: Exchange protocols (FIX, binary feeds) Market data normalization pipelines Contributions to systems like: Kubernetes etcd Experience optimizing systems for: Cache locality NUMA architecture CPU microarchitecture behavior
