Senior Golang Developer

Role Overview

Senior Golang Developer (multiple openings) for low-latency trading infrastructure and market data processing. Initially remote, the position focuses on building deterministic, high-throughput systems in Go for real-time ingestion and order routing.

Responsibilities

• 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 for deterministic execution, minimizing latency variance and tail latency
• Implement distributed coordination systems using consensus protocols (e.g., Raft/Paxos) where needed
• Create or optimize networking stacks / RPC frameworks tailored to trading workloads
• Work closely with Linux internals (syscalls, CPU pinning, NUMA optimization, kernel bypass techniques such as DPDK/Solarflare Onload)
• Optimize and troubleshoot using perf, eBPF, flame graphs, hardware counters, and profiling tools
• Debug production issues under live trading conditions to ensure stability and performance
• Partner with quants and traders to align system behavior with strategy requirements

Required Qualifications

• 10+ years of systems engineering or low-latency infrastructure experience
• 8+ years of production experience with Golang (Go)
• Strong knowledge of:
  • Concurrency and synchronization
  • Memory models and allocation behavior
  • High-performance system design
• Hands-on expertise in:
  • Lock-free programming and atomic operations
  • Multithreaded system design
• Strong knowledge of:
  • Linux internals and performance tuning
  • Networking fundamentals (TCP/UDP, multicast, low-latency pipelines)
  • Profiling and debugging tools
• Experience with:
  • High-frequency trading systems and/or market microstructure
  • Kernel bypass networking (e.g., DPDK, Solarflare)
  • RDMA / high-speed networking
  • Exchange protocols (FIX, binary feeds)
  • Market data normalization pipelines
  • Systems such as Kubernetes/etcd
• Ability to optimize for:
  • Cache locality
  • NUMA architecture
  • CPU microarchitecture behavior
