About LoopMe

LoopMe is an AI company solving one of advertising's hardest problems: making brand advertising actually measurable - and making it perform. Our platform runs patented machine learning models across billions of consumer signals in real time, optimising campaigns toward outcomes like purchase intent, brand lift, and foot traffic rather than proxy metrics like clicks. The result is 2-5x better performance than industry benchmarks, at scale.

We operate a high-load programmatic infrastructure - processing millions of ad requests per second with sub-200ms response times globally. This isn't a layer on top of someone else's stack; it's built from the ground up, in-house, by the team you'd be joining. Founded in 2012 and headquartered in London, we now have 400+ people across 19 cities and have sustained 40% revenue CAGR since 2018. The engineering problems here are real, the ownership is genuine, and the scale is significant.

The opportunity

You'll join a collaborative engineering team building and maintaining LoopMe's suite of self-serve advertising platforms, including our Supply, Exchange, and User Management products. Working across the full stack - Java 25 and Spring Boot on the backend, Angular 21 on the frontend - you'll design APIs and ship UI features used by international clients worldwide.

What you'll do

  • Build and maintain backend services and GraphQL/REST APIs powering LoopMe's Supply, Exchange, and User Management platforms
  • Develop frontend dashboard solutions in Angular based on newly designed APIs
  • Partner with Product Managers to discover, define, and deliver new features for dashboard applications
  • Research and evaluate new technologies - including AI-based features - to address evolving business challenges
  • Drive improvements to development processes and propose solutions to complex technical problems
  • Own unit testing on both frontend and backend to maintain high code quality standards

What you'll bring

Essential:

  • 2+ years of commercial frontend development experience, with strong JavaScript and TypeScript skills
  • 2+ years of commercial backend development experience, with Java
  • Experience with one or more modern frontend frameworks such as Angular or React
  • Solid working knowledge of SQL and REST API design
  • Basic experience with a cloud platform such as GCP or AWS

Nice to have:

  • Experience with E2E testing frameworks such as Playwright or Cypress
  • Familiarity with GraphQL on the consumer or provider side
  • Experience with gRPC
  • English at B2 level or above

What we offer

  • Flexible working schedule
  • 1 month work-from-anywhere
  • Annual performance bonus
  • English classes
  • LoopMe Gives Back
