  • Apply test‑driven development (TDD) and write robust automated tests for frontend code
  • Work closely with backend, platform, and DevOps engineers within cross‑functional teams
  • Contribute to technical and architectural decision‑making, particularly around frontend and cloud integration
  • Support and mentor other engineers, sharing frontend and cloud‑native best practices
  • Maintain high standards for performance, security, reliability, and maintainability in production environments

  • Strong expertise in React with JavaScript and TypeScript
  • Demonstrated experience building accessible, scalable, testable UIs
  • Strong understanding of modern frontend testing practices, including:

  • Component, integration, and UI testing
  • Solid practical experience working on applications hosted in Google Cloud Platform (GCP)
  • Familiarity with deploying, running, and supporting frontend applications in a cloud‑native environment
  • Strong sense of technical ownership and accountability for frontend delivery


Desirable (Bonus) Experience

  • Backend development using Java, ideally with Quarkus
  • Integration with REST APIs and relational databases such as PostgreSQL
  • Working knowledge of GCP services, such as:
  • Cloud Run, GKE, or App Engine
  • Cloud Build and CI/CD pipelines
  • Experience with containers and Kubernetes
  • Exposure to DevOps practices across build, deployment, and monitoring pipelines


What We’re Looking For
