We’re rebuilding Frontiers’ Publishing Platform — a manuscript-first architecture with embedded AI agents replacing legacy systems with modular, scalable services.
As a Senior Quality Engineer, you’ll work independently to embed quality throughout the development lifecycle, not just validate it at the end. You’ll shift testing left — spotting risks before code is written, building validation into CI/CD, and making autonomous calls on risk, coverage, and release readiness — while coaching the wider team to raise their own testing practices and use AI tools effectively.
Key Responsibilities
Drive validation strategy independently: what to test, at what level, and how — starting before development begins
Define test scenarios covering key flows, edge cases, and risk areas; challenge non-functional requirements (performance, reliability, security)
Build and maintain automated tests (API, integration, end-to-end) running continuously in CI/CD
Own release-readiness calls and post-release checks, using production signals (errors, logs, metrics) to close the loop




Coach the team on testing practices, shared quality ownership, and effective use of AI tools
Contribute to the wider Quality Engineering community and standards
5+ years in Quality Engineering / QA, with experience defining validation strategy independently
Strong systems thinking — able to spot risks and failure points across component interactions
Experience with API testing (REST Assured, Postman), integration/E2E testing, and CI/CD-integrated automation
Experience with performance testing (k6, JMeter)
Comfortable working with minimal oversight and making risk trade-off calls
Curiosity about AI-assisted testing tools
Nice-to-Have Skills
Contract testing (Pact), Playwright, BDD, large-scale migrations
Comfortable reviewing pull requests and contributing to test code when needed
We prioritise office presence and emphasise in-person collaboration, but also offer appropriate adjustments where needed, in line with co
