Founding Software Engineer - Backend
Hypercubic, San Francisco
The role
We’re looking for a backend engineer with unusually strong engineering and design taste. You will work directly with the CTO to design, prototype, and productionize AI-powered systems from first principles. This is a founding role with meaningful ownership over architecture, product direction, and engineering culture. It is suited for someone with strong fundamentals and comfortable operating across abstraction layers, from low-level system reasoning to high-level interactions.
What you will do
- Rapidly prototype new concepts and features to validate ideas before full implementation.
- Ship AI-driven features end to end, from model interaction to user-facing workflows.
- Set early engineering standards around testing, reliability, and code quality.
- Translate ambiguous problem statements into concrete experiments, constraints, and working systems.
- Lead architecture decisions and long-term technical direction with the CTO.
- Collaborate with a highly diverse group of subject matter experts and customers from various industries (banks, insurance, airlines, and more).
