Founding Engineer, AI Product

About the Role

Join the AI product team as a founding engineer, owning an agent-based product from concept through production. You will shape product and technical decisions while building user-facing features and the backend systems that power the platform.

What You'll Do

• Design and build user-facing features for an AI agent product, balancing usability with technical feasibility.

• Develop and maintain backend systems, APIs, and infrastructure for production AI workloads.

• Gather feedback, test product ideas, and ship improvements in rapid cycles.

• Own systems end-to-end, from architecture and implementation to deployment and monitoring.

• Collaborate with the founding team on product direction and technical strategy.

What We're Looking For

• At least 5 years of professional software engineering experience and a record of shipping products.

• Full-stack product engineering skills across frontend, backend, and production infrastructure.

• Hands-on experience building and deploying AI-powered products, LLM applications, or agent workflows.

• Experience owning systems from zero to one, ideally in a startup, founding-engineer, solo-builder, or early-stage environment.

• Comfort working through ambiguity and making decisions with incomplete information.
