Job Description
<strong><h2>About the Role</h2></strong><div>We’re building a <strong>runtime code sensor</strong> that operates where most tools don’t: <em>inside</em> running applications. Our goal is to give engineers and AI agents real-time, high-fidelity visibility into how code actually behaves in production – under real load, real traffic, and real failures.<br><br>This role blends <strong>deep systems engineering with applied research</strong>. You’ll dive into runtime internals, explore undocumented behavior, design low-overhead instrumentation, and turn research insights into production-grade components that safely run in customer environments. One day you might analyze GC or JIT behavior; the next, design tracing mechanisms that survive real-world distributed systems.<br><br>If you get excited about runtime internals, enjoy breaking (and fixing) complex systems, think like both a researcher and a production engineer, and care deeply about performance, safety, and correctness – you’ll feel right at home here. This is a <strong>hands-on, high-impact</strong> role for engineers who want to ship technology that engineers actually trust to run in their most critical services.</div>
