C++ Systems Engineer (Full-Time) Company Thunder Compute is a GPU cloud platform built on custom virtualization that delivers 5x better margins than competitors. 4-person team, seed-funded (approaching series A), 100%+ MoM revenue growth. 100% in-person in Atlanta, relocating to SF or NYC within 6 months. The technical challenge: We network-attach GPUs over TCP through API remoting, decoupling GPUs from instances. This lets us oversubscribe hardware aggressively—while Lambda Labs needs 100 GPUs for 100 users, we need 20. Making this virtualization layer stable and performant at scale is the hard problem we're solving. Role You'll work on the C++ core of our cloud platform: performance optimization, systems debugging, and research into oversubscription, checkpointing, and related problems. If you live in the weeds of complex, performance-critical systems, this is your role. Responsibilities Core technical skills: Top 0.1% C++ ability Experience optimizing NIC/GPU performance Deep understanding of low-level networking, compilers, or similar systems Experience in latency-sensitive environments Must haves: High potential for senior leadership as we scale Strong communication skills Self-driven (you'll own your work from day 1) Preferred CS PhD/Masters from top 50 US university, 3.5+ GPA (Bachelor's required) 1+ years at trading firm, hardware company (NVIDIA, SambaNova), or similar Compensation Full-time, salaried + 0.5-1% equity. We'll relocate our HQ for the right person. You'll report to Co-founder/CTO Brian (ex-Citadel quant dev).
