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.
