Software Engineer – AI Agents & Infrastructure

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.

Key responsibilities

• 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.

Required profile

• 2 to 5 years of professional software engineering experience; hands‑on individual contributor role (not staff, principal, or management).
• Strong proficiency in TypeScript and modern full‑stack product development.
• Hands‑on experience building with AI agents and LLMs using 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); not a fit if career spent exclusively at large tech companies, enterprise firms, or non‑tech orgs.
• Background as a founder or early engineer who 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.

Required skills

• TypeScript
• Full‑stack development
• AI agents
• Large Language Models (LLMs)

What we offer

• Salary range: $150,000 to $300,000 USD annually.
• Visa sponsorship is not available for this role.
• On‑site work in San Francisco; candidates elsewhere can apply with a concrete relocation plan.
