About the company
We’re rebuilding Frontiers’ Publishing Platform — a manuscript-first architecture with embedded AI agents replacing legacy systems with modular, scalable services.
About the role
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
