Software Engineer

About the Role This is a foundational engineering role at an early-stage B2B SaaS company building AI-powered integration infrastructure for supply chain connectivity. You will own core systems end-to-end, make architectural decisions that shape the product, and establish the engineering patterns the team will build on for years to come. What You'll Do Design and build purpose-specific AI coding agents from scratch to automate supply chain integrations. Develop and maintain core infrastructure for hosting and running integrations, effectively a self-contained integrations runtime 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's future direction. Work across both the agentic AI side and the complex, heavy infrastructure side of the product. What We're Looking For 2 to 5 years of software engineering experience, with a total range up to 8 years considered. Strong proficiency in TypeScript and modern full-stack product development. Hands-on experience building with AI agents and LLMs using current, production-grade patterns. Track record of shipping and owning complex software products end-to-end at a fast-moving startup. Experience at a VC-backed startup, ideally from seed through Series A or B. Demonstrated technical depth through shipped software systems, not just side work. Strong CS or engineering fundamentals, whether from a degree or equivalent work experience. Founding or early-stage engineering experience building 0 to 1 at a high-caliber startup is a strong plus. High-agency side projects, especially 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 Fully remote within the United States, with San Francisco, CA as the primary anchor location.
