Role Overview

Senior Golang Developer to design and implement low-latency services for trading infrastructure and market data processing.

Responsibilities

Build low-latency Go services for order routing and real-time market data ingestion.
Develop and optimize high-throughput data pipelines.
Implement lock-free / wait-free data structures and concurrency primitives for performance-critical execution.
Engineer systems with deterministic execution to minimize latency variance and tail latency.
Design and maintain distributed coordination systems using consensus protocols (e.g., Raft/Paxos) when needed.
Create or optimize networking stacks / RPC frameworks for trading workloads.
Work closely with Linux internals and performance tuning, including:
- Syscalls, CPU pinning, NUMA optimization
- Kernel bypass techniques (e.g., DPDK, Solarflare Onload)
Use performance tooling such as perf, eBPF, flame graphs, and hardware counters.
Debug production systems under live trading conditions, ensuring stability and performance.
Collaborate with quants and traders to align system behavior with strategy requirements.

10+ years in systems engineering or low-latency infrastructure.
8+ years of production experience with Go.
Strong knowledge of:
- Concurrency and synchronization
- Memory models and allocation behavior
- High-performance system design
Hands-on expertise with lock-free programming and atomic operations.
Experience building real-time / low-latency systems (trading/networking or similar).
Strong Linux internals and performance tuning.
Networking knowledge: TCP/UDP, multicast, and low-latency pipelines.
Profiling/debugging experience.
Exposure to high-frequency trading / market microstructure.
Experience with kernel bypass networking (e.g., DPDK, Solarflare) and RDMA / high-speed networking.
Familiarity with exchange protocols (e.g., FIX, binary feeds) and market data normalization pipelines.
Experience contributing to systems like Kubernetes / etcd.
Ability optimizing for cache locality, NUMA, and CPU microarchitecture.
