Founding Engineer

About the Role This is an early-stage agentic integration platform serving paying enterprise customers, and you will be the first engineering hire. You will own core systems end-to-end and set the technical patterns that every future engineer builds on, working hand-in-hand with the founders from day one. What You'll Do • Own the agent platform, infrastructure, and integrations runtime end-to-end. • Define the engineering patterns and standards that the growing team will build on. • Work directly with the founders, contributing technical opinion and leadership, not just code. • Ship production-ready, observable, and reliable systems continuously. What We're Looking For • 3 to 9 years of professional software engineering experience building and shipping production systems. • Demonstrated ability to build something from 0 to 1, whether at an early-stage startup or through a serious side project. • Strong background from an early-stage, venture-backed startup environment; a career spent exclusively at large tech companies, enterprise, or consulting does not meet the bar. • Proficiency in TypeScript and React for full-stack and frontend development. • Proficiency in Node.js for backend development. • Experience integrating or building workflows around large language models and agent-based platforms. • Hands-on experience with AWS for cloud infrastructure and PostgreSQL for data storage. • Experience owning end-to-end feature development across frontend, backend, and infrastructure with measurable customer impact. • Experience implementing observability, monitoring, and tracing in production systems. • Experience building reliable retry and queuing patterns in distributed systems. • A strong CS or engineering foundation, ideally from a rigorous degree program. • Genuine enthusiasm for joining as employee number one at a true early-stage company. Compensation & Benefits Salary range: $150,000 to $250,000 USD annually. Visa sponsorship is available where an O-1 visa is a realistic path. Location On-site, five days a week in San Francisco, CA . Candidates currently based in the Bay Area are preferred; US-based candidates with a concrete, dated relocation plan to San Francisco will also be considered.
