Senior Full-Stack AI Engineer - B2B Marketplace

About The Role

This is a founding-level engineering role at an early-stage, venture-backed AI SaaS company transforming how industrial manufacturers and distributors operate. You'll work directly alongside the founding team to build and scale the technical infrastructure powering an industrial B2B marketplace — from intelligent data pipelines and AI/ML systems to full-stack marketplace features that process transactions at significant scale.

This is a high-ownership, high-impact position best suited to a builder who thrives in fast-moving environments and wants to shape both product and technical strategy from the ground up. The interview process includes a two-week paid work trial.

What You'll Do

• Build and scale the technical backbone of an industrial B2B marketplace platform.
• Design and maintain data pipelines (Dagster or similar) ingesting data from thousands of manufacturers and distributors.
• Implement DevOps best practices and manage cloud infrastructure using CloudFormation and AWS.
• Develop AI/ML integrations and AI agent workflows that automate industrial sales and distribution processes.
• Deliver features across the full stack: Next.js / Vercel frontend, Supabase backend, and modern data infrastructure.
• Own end-to-end delivery of projects that directly enable large transaction volumes.
• Contribute to technical strategy as the platform scales from software tooling to a full marketplace.
