Software Engineer

About the Role This is an early-stage software engineering role at a seed-stage supply chain connectivity startup, where you will help build the foundational platform from the ground up. You will own core systems end-to-end, making architectural decisions that shape the product and engineering culture for years to come. The work spans both cutting-edge AI agent development and complex infrastructure, making it a uniquely broad and high-impact position. What You'll Do Design and build purpose-specific AI coding agents from scratch for supply chain connectivity use cases. Develop and maintain core infrastructure for hosting and running integrations, similar in spirit to a self-hosted deployment platform. Own systems end-to-end, from the agent platform to the integrations runtime, with full architectural authority. Establish engineering patterns and practices that will define the team and product going forward. Work across both the agentic and heavy infrastructure layers of the product simultaneously. What We're Looking For 2 to 5 years of professional software engineering experience; this is a hands-on individual contributor role and is not suited to staff, principal, or engineering management titles. Strong proficiency in TypeScript and modern full-stack product development. Hands-on experience building with AI agents and LLMs using current, production-grade patterns. Demonstrated ability to ship and own complex software products end-to-end with minimal direction. At least one tenure at a VC-backed startup (seed through Series B); a career spent exclusively at large tech companies, enterprise firms, or non-tech organizations is not a fit. Background as a founder or early engineer who has built products from zero to one at a fast-growing startup is a strong plus. Solid computer science or engineering fundamentals, ideally from a rigorous technical program. High-agency side projects, particularly agentic tools or launched products, are a meaningful signal. Compensation & Benefits Salary range: $150,000 to $300,000 USD annually . Visa sponsorship is not available for this role. Location On-site, five days a week in San Francisco, CA . Candidates based elsewhere in the US are welcome to apply with a concrete, dated relocation plan to San Francisco.
