About Creative Clicks

Creative Clicks is a high-growth performance marketing company building and scaling data-driven digital products globally. We operate across 65+ countries, combining the speed of a startup with the scale of an international organisation. Our engineering team builds the platforms and services that power our mobile apps, internal tools, and product infrastructure.

About the role

We're looking for a senior product engineer first — someone who picks up a feature, designs it end-to-end, writes the code, and ships it to production with tests that catch real regressions. You'll work across our Next.js front-end and NestJS back-end, collaborating closely with Product, Design, Mobile, and BI.

This is a hands-on role for someone who likes to own things from idea to production and who uses modern AI coding tools as a natural part of their workflow.

What you'll do

• Build and maintain scalable backend services using Node.js, NestJS, TypeScript, Prisma, and PostgreSQL

• Develop clean, performant frontend applications using Next.js (App Router, RSC) and React

• Design and optimise APIs consumed by mobile apps (Flutter) and internal tools

• Own database design, migrations, indexing, and performance optimisation across a large Prisma schema

• Implement secure authentication and authorisation flows (JWT, OAuth) with GDPR awareness

• Write high-quality, testable code — unit, integration, and E2E tests that catch real regressions, not coverage filler

• Deploy and operate services on AWS (EKS, Docker, CI/CD, Helm)

• Write clear technical documentation: RFCs when proposing changes, postmortems when regressions slip through

What you bring

• 3–5 years shipping production full-stack TypeScript; you've led non-trivial features end-to-end

• Deep knowledge of Next.js — App Router, React Server Components, React 19 runtime, route handlers, middleware

• Deep NestJS + Prisma — controllers, services, guards, interceptors, DTOs with class-validators are second nature

• Strong TypeScript — you use the type system to prevent bugs

• Solid testing instinct — you write tests that catch real regressions, not coverage theatre

• Fluency with modern AI coding tools (Claude Code, Cursor, Copilot, or similar) — you use them daily and can compose AI-generated code into something coherent and maintainable

• Experience designing and maintaining REST APIs

• Production experience on AWS; familiarity with Docker, Kubernetes (EKS), and CI/CD pipelines

• Comfortable in a regulated environment (GDPR, data privacy) — or demonstrably ready to learn

• Good written communication: clean RFCs, clear postmortems, no ambiguity
