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
