Job summary

Frontiers is rebuilding its Publishing Platform with a manuscript-first architecture and embedded AI agents. As a Senior Quality Engineer, you will embed quality throughout the development lifecycle, shift testing left, and coach the team to raise testing practices and adopt AI tools.

You will define validation strategy, build automated tests, and leverage production signals to ensure release readiness while collaborating across teams in a fast-evolving environment.

Qualifications

• 5+ years in Quality Engineering with independent validation strategy.
• Strong systems thinking to spot risks across component interactions.
• Experience with API testing (REST Assured, Postman) and CI/CD automation.
• Experience with performance testing (k6, JMeter).
• Comfortable working with minimal oversight and curiosity about AI-assisted testing tools.

Responsibilities

• Define validation strategy independently: what to test, at what level, and how, 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) in CI/CD.
• Own release-readiness calls and post-release checks using production signals to close the loop.
• Coach the team on testing practices, shared quality ownership, and effective use of AI tools.
