Job Title: Senior Golang Developer

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.
