Overview
Job Posting: Product Engineer (Full Stack & AI-Native)
Location: Remote (UK-based preferred for timezone alignment) Type: Contract / Freelance (with potential for long-term partnership) Stage: Stealth Mode / Pre-Launch
The Opportunity
We are a stealth-mode startup building a premium digital ecosystem designed to solve the "Connectivity Paradox" in the UK business market. We are bridging the gap between social networking and high-value transactional brokerage for business owners and investors.
We are looking for a Product Engineer—not just a ticket-taker, but a builder who understands that code is a means to a business end. You will work directly with the Lead Product Manager/Architect to build, ship, and iterate on our MVP.
This is not a traditional dev role. We embrace an Agentic SDLC. We don't want you typing boilerplate; we want you architecting solutions, utilizing AI tools (Copilot, Agents) to accelerate velocity, and applying your seniority to review, secure, and deploy that code.
The Stack
* Frontend: React, Next.js (App Router), Tailwind CSS, Framer Motion.
* Backend: Supabase (Auth, Database, Edge Functions).
* Payments: Stripe Connect & Subscriptions.
* Tooling: GitHub Copilot, Cursor, or OpenCode (AI-assisted workflow is mandatory).
* Mobile (Future): React Native / Expo.
What You Will Do
* Build the Engine: Execute on a high-fidelity Product Requirements Document (PRD) to deliver the web-based MVP.
* AI-Augmented Development: Act as the "Senior Architect" to an AI "Junior Developer." You will use AI to generate foundational code, but you are responsible for reviewing, refining, and securing it.
* Security Gatekeeper: specifically regarding AuthZ/AuthN and Payments. You must ensure no AI-generated hallucinations introduce vulnerabilities in our logic.
* Ship Fast: We have a tight delivery roadmap. You will move from "File > New" to "Production" in weeks, not months.
* Voice of the Product: Provide feedback on UI/UX and logic. If a feature seems over-engineered, we want you to push back with a simpler solution.
Who You Are
* A "Product" Engineer: You care about the user experience as much as the database schema. You can look at a mock-up and fill in the blanks without needing a 20-page spec for every button.
* AI-Pragmatic: You understand the risks and rewards of AI coding tools. You know how to prompt for complex logic and how to spot the subtle bugs AI leaves behind.
* Supabase Expert: You are comfortable with Row Level Security (RLS) policies and don't need to spin up a custom Express server when a serverless function will do.
* Senior Mindset: You write clean, maintainable code but understand that "perfect" is the enemy of "shipped."
Bonus Points
* Experience with Expo/React Native (we have a mobile fast-follow planned).
* Experience building Directory or Marketplace platforms.
* Knowledge of UK GDPR compliance requirements.
Why Join Us?
* High Impact: You are building the foundation of the platform, not maintaining legacy code.
* Modern Workflow: We use the latest tools to remove friction. No red tape, just shipping.
* Strategic Partnership: For the right candidate, this role offers high visibility and the potential to evolve into a technical leadership position as we scale.
* To Apply: Please share your portfolio/GitHub and a brief note on your experience with Supabase and AI-assisted coding workflows.
