About the role

About the Role

A well-funded, seed-stage B2B SaaS startup in the supply chain integrations space is looking for a Founding Software Engineer to help shape the architecture, culture, and product direction of an agentic integrations platform. This is a high-ownership role where you'll work across the full stack and have a direct impact on the company's trajectory from day one.

What You'll Do

  • Build and evolve the integrations platform — including mapping, testing, retries, queues, observability, and the full infrastructure layer.
  • Work across the entire stack: frontend (TypeScript, React), backend (Node.js), infrastructure (AWS), and LLM/agentic workflows.
  • Own projects end-to-end, from initial specs through implementation to measurable customer impact.
  • Help define product direction, engineering culture, and company-building decisions as an early team member.

What We're Looking For

Required:

  • 3+ years of software engineering experience, ideally in fast-paced startup environments.
  • Demonstrated experience building products 0→1, either at an early-stage startup or through serious side projects.
  • Strong proficiency in TypeScript and React for frontend, and Node.js for backend.
  • Experience integrating or building workflows around large language models (LLMs) and agent-based platforms.
  • Hands-on experience with AWS for cloud infrastructure and PostgreSQL for data storage.
  • Experience owning end-to-end feature development across frontend, backend, and infrastructure.
  • Familiarity with observability, monitoring, distributed tracing, and reliable retry/queuing patterns in distributed systems.
  • Strong computer science fundamentals.

Nice to Have:

  • Experience in supply chain, logistics, or enterprise integration domains (EDI, ERP, WMS, TMS, etc.).
  • Familiarity with Vercel and Tailwind CSS.

Compensation & Benefits

  • Salary: $130,000 – $200,000 USD annually
  • Visa sponsorship available
  • Early-stage equity opportunity as a founding team member
