Founding Fullstack Engineer

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, , TypeScript) and backend environments , Python).
• UI/UX Fluency:
  You are comfortable with CSS, Tailwind, framer-motion, and component libraries.
• Database & API:
  Strong skills in database design (PostgreSQL) and building clean, RESTful/GraphQL 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.
• Competitive Salary:
  $160-250K
