We’re building something special, and we want someone like you at the center of it. Our platform is used by tier-one banks, hedge funds, and trading firms to identify latency bottlenecks and other issues in high-performance electronic trading environments.
Instead of throwing money and hardware at problems, our platform quickly identifies the real issues with insight only a team of trading system performance engineers and ex-technical traders can provide.

This is a rare chance to learn from top engineers in capital markets monitoring, gaining early exposure to high-performance, real-time trading systems. You’ll work hands-on with Linux, network analysis, SQL, Python, time-series databases, and an award-winning observability platform, contributing to client POCs and live deployments.
