Staffing & Recruiting

Responsibilities

You'll build high-performance C++ systems that process enormous volumes of data with brutal latency constraints. Think lock-free algorithms, cache-aware data structures, and the kind of optimization work where you're reading compiler output and thinking about branch prediction

The problems are legitimately hard. Taking a complex technical challenge and producing something elegant that also screams 'that's the craft'. You'll work directly with brilliant engineers and researchers who care about both theoretical correctness and practical performance. Ideas move from whiteboard to production fast, and you'll own what you build all the way through

This means monitoring your systems in prod, debugging the weird behavior that only shows up under real load, and continuously making things better. The feedback loop is immediate. The impact is measurable. The work is real

Required

You write serious C++. Not just syntactically correct code, but the kind that makes other engineers say 'oh, that's clever' when they read it six months later

MINIMUM OF 2-6 years PG experience in production; ideally on core systems

You understand how computers actually work. Memory hierarchies, concurrency primitives, thread scheduling; you know why these things matter and how to make them work in your favor

You're intellectually curious. When something is slow, you want to know why. When a system behaves unexpectedly, you dig until you find the root cause

You communicate clearly and own your work. High-ownership environment means exactly that; you're trusted to make decisions, ship code, and live with the consequences

You have a degree in Computer Science, Engineering, or something that convinced you computers are interesting
