Job Description
Why Join This is a rare opportunity to join a fast‑growing AI + data infrastructure company where engineering owns the product. You'll build the foundational systems that every vertical (healthcare, finance, coding, etc.) depends on — and your work will directly determine the company's ability to scale. Why top engineers are excited about this role: Massive ownership — you will architect the core infra the entire company builds on High‑talent density — small team, no passengers, everyone is an A‑player Real impact — your work unlocks new verticals and accelerates product velocity Elite compensation — base + equity + 4% gross‑profit share (often $300K+ in bonus potential) Fast career trajectory — you'll mentor the entire junior engineering team Hard engineering problems — distributed systems, infra reliability, scalability, observability If you want to build foundational systems at a company scaling aggressively, this is the role. About The Role We're looking for a Senior Software Engineer (6–8 YOE) who is full‑stack but infra‑oriented , capable of designing and owning the core platform that powers all product verticals.
