Senior Golang Developer

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.
