Overview

We’re looking for a senior, highly autonomous Test Automation Engineer to own and evolve the testing strategy for a complex, containerised microservices platform. This role goes far beyond writing test scripts — you’ll shape how testing is designed, executed, and scaled across the system.

Responsibilities

You’ll work with Dockerised Java services, treating each microservice as a black box to build meaningful integration and E2E coverage.
You’ll modernise existing automation, extend Python-based tooling, and influence performance testing and CI/CD strategy (GitLab).
Will work on Frontend automation built by using TypeScript + Playwright, while backend services communicate via mechanisms such as SNS queues.

Key Skills & Experience

Senior-level automation engineering experience in distributed systems
Strong integration and E2E testing design for microservices
Docker/containerised test environments
TypeScript & Playwright (frontend automation)
Backend/API testing (event-driven or async systems)
Python tooling for test support
CI/CD integration (GitLab preferred)
Performance testing mindset and experience

If you would like immediate consideration, please send me an updated CV/contact details to jcaria@redglobal.com so we can discuss further or reach out to me through LinkedIn.
