Founding Fullstack Engineer

You'd be Jampack's first in-person engineering hire in New York, working next to Rezi, co-founder and CTO, as the team moves its center of gravity to the city this month. Four engineers build the platform remotely today, each owning one integration. This seat is different: you own the core.

The core is the scaffolding around the AI, not the model. Data pipelines, integrations, APIs and the operator console that connect Jampack's agents to ERPs, 3PLs, retailers and freight partners, and keep them running when downtime means missed shipments and chargebacks.

Jampack automates the wholesale order-to-cash lifecycle for CPG brands like Fishwife, Immi and PATH: purchase order ingestion, freight coordination, invoicing and payment reconciliation. Wholesale is 7x the size of e-commerce and still runs on spreadsheets and email chains. The company raised a $3.2M seed led by Maveron and is five people.

What You'll Do

• Take customer-facing features from concept to production. You'll talk to users, design the solution, build it, and watch them use it.
• Design secure, auditable data models and event-driven pipelines that power the 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, plus a resilient sync layer that keeps everything in lockstep.
• Establish observability, SLOs and on-call practices for mission-critical workflows.
• Work across the full stack, backend, data engineering and frontend, wherever the highest-leverage problem lives.

What We're Looking For

• A strong full-stack base and a record of building robust, reliable production systems.
• You lead work end to end without waiting for direction, and you don't wait for someone else to build the other half.
• TypeScript/Node, Postgres, queues or streams, and a cloud platform (AWS or GCP).
• Systems thinking paired with product intuition: developer experience and operator experience matter equally.
• Startup or small-team experience. Big-tech time is welcome; five years of only big tech usually isn't a pace match.
• Early in your career? Strong pedigree gets you in: a top school, a YC startup or a short big-tech stint.

How Jampack Hires

• First call with Rezi.
• Take-home in two parts, about four hours, returned within two to three days.
• Walkthrough of your take-home with both founders.
• References, then offer.
