Core Engineer_TT

This Core Engineer hire exists to build robust full-stack systems that integrate with complex legacy environments and support high-value supply chain operations. The ideal candidate is a highly motivated, fast-shipping engineer who thrives in ambiguous, fast-paced environments — a backend-leaning full-stack developer proficient in TypeScript, Svelte (or React/Next.js), and Postgres. Open to any seniority level, including new grads, provided they can architect systems independently and demonstrate end-to-end project ownership. Must be willing to work strictly on-site in San Francisco.

Details

• Employment: Full-time
• Seniority: Mid-Senior Level (open to strong new grads who can own systems end-to-end)
• Core stack: TypeScript, Svelte, PostgreSQL, Python, React, Next.js
• Visa & work authorization: US citizens or current visa holders preferred; sponsorship available (E2/O-1). Physical relocation to San Francisco strictly required.
