Founding Engineer (Full-Stack) for B2B SaaS Supply Chain Platform

We're hiring a founding engineer to own the product's technical foundation. You'll take a working v1 and turn it into production-grade software manufacturers run their businesses on, deciding how it's built, how it scales, and how the engineering team works as it grows.

🔨 What You'll Do

• Own the codebase and architecture end to end, starting with an audit of v1 and a plan for what to keep, rebuild, and harden.

• Ship full-stack features across Python, FastAPI, SQLAlchemy, PostgreSQL, WebSockets, and Next.js.

• Build integrations with manufacturers' ERP systems and other third-party tools so order, inventory, and production data flow into the product without manual entry.

• Design and evolve the data model as the product expands, with clean, reversible Alembic migrations.

• Build the real-time layer that keeps manufacturers and brands looking at the same status, documents, and messages.

• Own infrastructure, deployment, and monitoring.

• Join design partner calls and turn what you hear into product decisions.

• Help shape how AI shows up in the product as we build it.

• Set the engineering bar and help hire the engineers who come next.

🔎 You May Be a Good Fit If You

• Have 5+ years building production software, with real ownership of systems across the front end and back end.

• Have shipped a product from 0 to 1, ideally as an early engineer at a startup.

• Write Python and TypeScript fluently, and have built with FastAPI (or similar) and React or Next.js.

• Know PostgreSQL well, from schema design to query tuning and migrations.

• Have integrated with external systems and know what it takes to make them reliable: retries, idempotency, and sync conflicts.

• Make product and prioritization decisions instead of waiting for specs.

• Push back on ideas, including the founder's, and bring a better option.

• Treat tests, monitoring, and clean deploys as part of shipping, not extra work.

• Use AI tools every day to move faster.

• Write clearly and enjoy working closely with a hands-on, detail-oriented founder.

Bonus skills:

• Experience with ERP systems (e.g., NetSuite, SAP Business One, Acumatica, or QuickBooks) or with supply chain, manufacturing, or B2B operations software.

• Built real-time features with WebSockets.

• Shipped AI or LLM-powered features, such as document extraction or retrieval.

• Side projects that show range and initiative.

🤝 Who We're Looking For

This is a founding hire, so cultural fit matters as much as technical skill. We're looking for someone hyper-collaborative and clear in communication, comfortable working closely — in person — with a very hands-on, detail-oriented founder. You take initiative and ownership rather than waiting to be told what to do, and you're energized by building something from zero rather than maintaining something established.

Location: remote, based in Brazil or US, with regular in-person work sessions with the founder in the early months. Expect occasional travel to manufacturing sites to see how our users work on the production floor.
