About the 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
