Founding Engineer (Full Stack)

About this role

ABOUT THE ROLE

You'll be one of the first two founding engineers setting the technical culture for a fast-growing team. The company has seen rapid growth and just closed funding to scale. You'll work across the entire technical stack with significant ownership and autonomy.

WHAT YOU'LL DO

- Own problems end-to-end across multiple technical domains: LLM orchestration, conversation flow, tool integration, voice, UI, and infrastructure

- Debug production issues in real-time—from conversation logs to deployment regressions—and ship fixes quickly

- Design and prototype new features with minimal specification, from generative UI to agent versioning systems

- Build and maintain the core technical pillars: agent orchestration, embeddable adaptive UI, customer-facing platform, evaluation pipelines, and zero-cold-start infrastructure

- Write and iterate on evals that measure system quality and feed improvements back into the product

- Handle the full spectrum of early-stage work: frontend bugs, database migrations, customer debugging, and infrastructure design

WHAT WE'RE LOOKING FOR

- Proven track record shipping systems that real users depend on. You can speak to what actually broke in production and how you fixed it

- Strong engineering judgment about what's ready to ship versus what needs more work. You move fast without creating hidden technical debt

- Hands-on experience making LLM systems work at scale. You understand the gap between demo and production, and you know how to close it through design and iteration

- Comfortable working across the stack—not for the title, but because the hardest problems don't fit into one layer

- Ability to take ownership without waiting for direction. If something is broken or unclear, you fix it

- Pragmatic about technology choices. You pick tools based on the problem, not preference
