We’re looking for a Full-Stack Software Engineer to join our Platform Performance team and help us deliver lightning-fast, scalable experiences to millions of users around the world.

In this role, you’ll work across the stack-sharpening frontend speed, optimising backend services, and making our user interfaces more responsive, reliable, and delightful to use. You’ll collaborate with passionate engineers and product managers to identify performance bottlenecks, contribute to architectural improvements, and help evolve our design system.

What You’ll Do

  • Identify and solve performance issues across both frontend (Angular) and backend (PHP, Python, Go).
  • Optimise page load speed, rendering performance, and API response times.
  • Contribute to our design system and build reusable UI components using Angular and TypeScript.
  • Help maintain and evolve scalable backend systems for high-performance APIs.
  • Collaborate with cross-functional teams to implement best practices in performance, usability, and accessibility.
  • Participate in architecture discussions and continuously improve our codebase and tooling.
  • Promote and support performance monitoring and testing practices.

What We’re Looking For

  • Professional experience as a full-stack or frontend engineer.
  • Solid experience with Angular and TypeScript.
  • Comfort working with backend technologies like PHP, Python, or Go.
  • A good understanding of frontend performance optimisation techniques.
  • Familiarity with RESTful API design and backend performance considerations.
  • Experience building and maintaining reusable UI components.
  • Exposure to design systems or component libraries.
  • Strong communication skills and a collaborative mindset.
  • A proactive attitude, with the ability to take ownership and see tasks through.

Bonus Points (Nice to have)

  • Understanding of accessibility and UI/UX design principles.
  • Familiarity with SEO and frontend performance metrics.
  • Experience with automated testing (Jest, Cypress, PHPUnit, etc.).
  • CI/CD or DevOps knowledge.
  • Open-source contributions or personal projects.

Why Join us

  • Work on a platform with global impact - we’re on a mission to create one billion jobs.
  • A culture that values ownership, transparency, and meritocracy.
  • Fast-track your growth with mentorship, real ownership, and exposure to internet-scale challenges.
  • Weekly CEO town halls, quarterly hackathons, and team events to keep you engaged and inspired.
  • A chance to help build the tools and systems that power the next generation of our platform.
