Founding Engineer - Fullstack

About

About Jampack AI

Jampack AI is an AI platform that automates wholesale operations for consumer brands, handling workflows like purchase orders, logistics, and invoicing end-to-end. It acts like an “AI agent” for supply chains—connecting systems and replacing manual work so companies can run distribution faster, with fewer errors and less operational overhead.

About the role

The moat is not the model. It is the scaffolding. The software infrastructure around the AI connects to real-world systems, ERPs, 3PLs, retailers, and freight partners, delivering real-world reliability. That is what you will build. Jampack is hiring a Founding Full Stack Engineer to own the core platform powering their AI agents and customer experience. You will talk to users, design solutions, ship to production, and watch real customers use what you built. The product is live with fast-growing CPG brands, and the next step is to deepen the platform, scale the integrations, and make it reliable enough for brands to trust with their entire wholesale operations. You are building mission-critical infrastructure in a market that has barely been touched by modern software. Downtime means missed shipments and chargebacks for real brands. The stakes are high, and the ownership is real.

What you'll own

• Take customer-facing features from concept to production. Talk to users, design the solution, build it, and watch them use it
• Design secure, auditable data models and event-driven pipelines that power AI agent workflows
• Develop internal and external APIs and a real-time operator console that gives customers full visibility into their operations
• Build first-party integrations with ERPs, 3PLs, retailers, and freight partners, and a resilient sync layer that keeps everything in lockstep
• Establish observability, SLOs, and on-call practices for mission-critical workflows where downtime means missed shipments and chargebacks
• Work across the full stack, backend, data engineering, and frontend, wherever the highest-leverage problem lives
• Technical
• 2 to 5 years of software engineering experience, ideally including time at a high-agency startup where you owned product work end-to-end
• Strong proficiency in TypeScript and Node.js, the core stack at Jampack
• Postgres for data modeling and query performance
• Full-stack capability, including React for customer-facing product surfaces
• Comfortable with event-driven pattern, webhooks, async workflows, integrations that keep external systems in sync
• Execution and Ownership
• Takes a customer problem or vague feature idea and runs it to production without waiting for specs
• Researches the right approach before building, and chooses the simplest thing that will actually work
• Cares about reliability — this is mission-critical infrastructure where downtime means missed shipments for real brands
• Hungry, committed, and "all-in" on an early-stage startup pace. Not 9-to-5, not 996 — reachable when things break, and honest about what that requires
• Communication
• Clear, direct communicator who can talk to non-technical customers when needed and translate their workflows into software
• Low ego, collaborative, works directly with the two co-founders every day
• Location
• Hybrid in Brooklyn, NY (WeWork). Strong preference for in-person most of the week
