Software Engineer

About the Role We're an early-stage SaaS company building a platform to automate mission-critical integrations for the real economy — specifically focused on supply chain connectivity. We're looking for a Software Engineer with 3–8 years of experience who brings strong technical horsepower, sharp judgment, and a genuine drive to build foundational systems from scratch in a fast-moving environment. This is a high-impact, high-ownership role where you'll make architectural decisions that shape the product and engineering culture for years to come. You'll work across both cutting-edge AI/agentic systems and complex infrastructure — no silos, no hand-holding. Visa sponsorship is not available for this role. What You'll Do Design and build purpose-specific AI coding agents from scratch, tailored for supply chain connectivity use cases. Develop and maintain core infrastructure for hosting and running integrations — effectively a mini-runtime/deployment platform (think Vercel, but purpose-built for our stack). Own core systems end-to-end: from the agent platform to the integrations runtime. Make foundational architectural decisions that will define the platform's future. Establish engineering patterns and best practices that scale with the team and product. Work fluidly across the agentic AI layer and the heavy infrastructure layer of the product. What We're Looking For Must-haves: 3–8 years of experience as an individual contributor software engineer. Strong proficiency in TypeScript. Undergraduate degree in Computer Science, Engineering, or a related field. Proven track record of shipping and owning complex software products end-to-end. Hands-on experience building with or using AI agents and/or Large Language Models (LLMs). Experience building platform engineering or infrastructure systems (e.g., runtimes, execution environments). Nice-to-haves: Prior experience at a developer tools or infrastructure-focused company. Familiarity with any of: React, Bun, Effect-TS, PostgreSQL, Kubernetes, or AWS. Background from a top technical university. Compensation & Benefits Salary: $150,000 – $300,000 per year, depending on experience. Early-stage equity opportunity. Direct impact on product direction and engineering culture from day one. Location This is an on-site role based in Los Angeles, CA. Candidates should be local or willing to relocate. Visa sponsorship is not available.
