About the role
We're looking for a Founding Engineer (Full-Stack) with 3+ years of experience (or 2+ years at VC-backed startups) who has owned and shipped end-to-end projects at companies with strong engineering cultures. You should be comfortable working across the entire stack — roughly 70% backend, 30% frontend — and have a track record of building consumer or prosumer products with measurable impact. Bonus points if you've worked on AI agents, LLM integrations, or automation platforms.
What you'll do
- Build and harden core platform capabilities — including voice, browser automation, and multi-agent orchestration — that power AI agents executing complex multi-day workflows for enterprise customers
- Own features end-to-end from understanding customer requirements to shipping production-ready code, acting as a product owner rather than waiting for specs
- Work directly with customers (5–20% of your time) to understand their workflows, gather requirements, and translate operational needs into platform improvements
- Reverse-engineer customer systems, build integrations with tools like Salesforce, Outlook, TMS, and ERP platforms, and connect them into Runbook's agentic orchestration layer
- Ship frontend experiences in React that make complex AI agent workflows intuitive and delightful for enterprise operations teams
- Collaborate closely with a small, high-caliber founding team (reporting to the CTO) to set technical direction and architectural decisions that will define the platform for years to come
