Full Job Description
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 COMPENSATION & DETAILS Work Arrangement: Full-time, founding-level role LOCATION Remote or onsite options available
