Notify (CCN) is an international platform helping collectors source limited and in-demand items at retail price. With 50,000+ monthly active users and accelerating growth, we're looking for an exceptional Senior or Lead Full Stack Developer to take full technical ownership of our product.

About the role

This is a rare opportunity to join as the first full-time developer at a company with proven product–market fit and serious momentum. You'll be taking over from a freelance development team — with a structured handover period in place — before stepping into full ownership of our React Native app and Django backend.

We're not looking for someone who clocks in and clocks out. We want someone who buys into the product, cares deeply about craft, and wants to build something truly world-class. In return, you'll have real autonomy, real impact, and a front-row seat at a company in full growth mode.

The stack

Frontend: React Native · Expo Bare

Backend: Django · Docker · AWS · SQL

What you'll be doing

• Take full technical ownership of the React Native app and Django backend, driving architecture decisions end-to-end

• Lead a structured handover from the existing freelance team, establishing clear engineering standards from day one

• Build and maintain scalable, production-grade systems capable of supporting rapid international growth

• Set coding standards, review processes, and deployment pipelines that raise the bar across the entire codebase

• Collaborate closely with the founding team on product direction, technical feasibility, and roadmap planning

• Own infrastructure decisions on AWS — performance, reliability, cost efficiency, and security

What we're looking for

• Proven experience with React Native (Expo Bare) and Django — production apps, not just side projects

• Deep low-level knowledge across the full stack — from how TCP/IP and transport layers move data, to how native device layers interact with JS, to how your database behaves under load. You read RFCs for fun and care about why things work, not just that they do

• Fluency with AWS infrastructure and Docker-based deployments

• Solid SQL knowledge — schema design, query optimisation, and databases at scale

• A track record of writing code that others can inherit, maintain, and build on

• Fluent with modern AI coding tools — Claude Code, Cursor, and similar. We actively embrace these to accelerate development, but we want someone who uses them with full understanding. You read every change, cross-check it against your own judgement, know exactly what's being introduced and why, and never let generated code slip through that you can't defend.

• A self-starter mindset — proactive, accountable, and energised by ownership

What we offer

• Salary: £70,000 – £95,000 depending on experience

• Full-time, Monday to Friday

• Real technical ownership from day one

• A structured onboarding and handover period

• Direct influence on product and architecture at a critical growth stage

Pay: £70,000.00-£95,000.00 per year

Experience:

• Software Development: 5 years (required)
