Founding Fullstack Engineer

Cofounder @ Jampack | Automating CPG Ops with AI

Company Description

Jampack is revolutionizing the wholesale industry by building autonomous AI agents that power operations for modern consumer brands. Wholesale is 8X the size of e-commerce, yet has been woefully underserved — until now.

We help the world’s most exciting emerging brands—like Ghia, Fishwife, and Cascade Water—automate the manual, repetitive tasks that bog them down. By saving our customers 20+ hours a week, we empower them to focus on what matters most: growth.

We are a high‑velocity team building tools that don’t just "work" — they feel magical to use.

Role Description

We are looking for a Founding Fullstack Engineer who is obsessed with shipping products from 0 to 1. This is not a "take a ticket and code it" role. You will be a core partner in defining what we build, not just how we build it.

You are a builder who views software as a craft. You have the engineering chops to architect a scalable backend, but you also have the design sensibility to know when a UI interaction feels "off." You sweat the details on padding, animations, and latency.

What We’re Looking For:

• 0 to 1 Builder: You thrive in ambiguity. You can take a one‑sentence problem statement and turn it into a deployed feature.
• High Agency: You don’t wait for permission or detailed specs. If you see a gap in the product or a bug in the code, you fix it. You act like an owner because you are one.
• Design‑First Engineering: You don’t just tolerate frontend work; you enjoy it. You understand that for non‑technical users, the interface is the product.
• Product Sense: You care about the "Why." You are opinionated about the user experience and willing to push back if a feature doesn’t solve the user’s actual problem.

What You’ll Do

• Ship Fast & High Quality: Design and develop end‑to‑end features (Frontend + Backend) with a focus on speed‑to‑market and polished UX.
• Architect for Scale: Build robust backends to power our AI agents, handling data synchronization and complex workflows.
• Own the UI: Implement pixel‑perfect interfaces that delight our users.
• Collaborate: Work directly with the founders to shape the roadmap and technical strategy.

Qualifications

• Expert Fullstack Proficiency: Deep experience with modern frontend frameworks (React, Next.js, Type Script) and backend environments (Node.js, Python).
• UI/UX Fluency: You are comfortable with CSS, Tailwind, framer‑motion, and component libraries.
• Database & API: Strong skills in database design (Postgre
  
  SQL) and building clean, RESTful/Graph
  
  QL APIs.
• AI Proficiency: Experience building applications that leverage LLMs and AI agents.
• Startup Scrappiness: Experience with Vercel, Supabase, AWS, or similar tools to get things live quickly.
• Bachelor's or advanced degree in Computer Science, Software Engineering, or related discipline, or equivalent professional experience.

Why Join Jampack?

• Founding Equity: Significant ownership in the company.
• Tangible Impact: Your code will directly help fast‑growing brands operate better. You will see the results of your work immediately.
• In‑Person Culture: We believe the best 0‑1 work happens in the same room. Join us in our NYC office.
