Note: The job is a remote job and is open to candidates in USA. Mastermind.com, through AI Advantage, operates a large education platform for real customers. The Full Stack Product Engineer will build and own backend-heavy full-stack tooling, including a customer service admin suite, member experience integrations, and affiliate systems, using Node.js, React, and related technologies. The role emphasizes autonomous end-to-end delivery, quality assurance, peer review, and adaptability in a fast-moving team.

Responsibilities

• Build a unified admin panel that lets a non-technical customer team fix accounts end to end in one click
• Own the plumbing that carries the whole company from point of sale into Circle
• Move work from to-do to done with clean hygiene and no one chasing you
• Own your own QA and ship through peer-reviewed pull requests, never work thrown over a wall
• Say "I don't think this is fully thought through, let's talk it through" before you write a line of code
• Set down yesterday's work for today's when priorities shift, without getting precious about it
• The unified admin panel that lets Customer Service take a client end to end: one-click account, billing, and login fixes across one tool instead of five
• The Circle member experience (login, billing, account management, lead flows) and the plumbing that connects our commerce stack to it, running smoothly end to end
• Maintain, extend, and improve the affiliate system that drives growth
• Own your work all the way to production: validate it yourself, walk a reviewer through your test cases, and ship through peer review
• Keep clean progress and surface blockers early

• Front-end: Next.js, React, TypeScript, Tailwind, iframes
• Backend: Node, Express, MySQL, Redis

• Collaborative problem solving: you think fast with the team and pressure-test the plan before building, no rogue players

• US citizens and green card holders only. No visa sponsorship
• AI coding tools used well (Claude Code, Cursor), with the judgment to verify and own the output
