Jobs at Substrate

Build and ship core 0-to-1 systems connecting software, hardware, and finance. Responsibilities include designing abstractions over complex data and legacy systems, owning the full product lifecycle, developing production-grade LLM systems for loan underwriting and compliance, and contributing to engineering and product culture. The role requires strong backend and systems thinking, with comfort in full-stack development and UI design.

Own the full product arc from customer pain through UI/UX design, prototyping, copywriting, and shipped experiences. Design and build simple interfaces over complex legacy systems, create high-fidelity mockups, write growth-focused product copy, implement basic backend changes, and help shape a product culture centered on speed, craft, and customer obsession.
