Founding Engineer - Fullstack

Jampack is hiring a Founding Full Stack Engineer to own the core platform powering its AI agents and customer experience. You will talk to users, design solutions, ship to production, and watch real customers use what you built, working directly with the two co-founders every day. 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. This role is hybrid at Jampack’s WeWork in Brooklyn, NY, with most of the week in person.

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.

You are building mission-critical infrastructure in a market modern software has barely touched. 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
