About the Role We are seeking a Senior Quality Engineer responsible for ensuring the quality, stability, and production readiness of software delivered across engineering teams. This role focuses on test strategy, automation engineering, release validation, and quality governance across complex distributed systems.

The role requires strong technical depth, ownership mindset, and the ability to operate across engineering, product, and DevOps functions in a fast-paced Agile environment.

The Senior Quality Engineer is responsible for ensuring every engineering change is production-ready, reliable, and aligned with system-level quality expectations. This role owns the end-to-end quality lifecycle across development, enhancements, and releases, ensuring software is validated not only against requirements but also for real-world reliability and edge-case behavior.

This includes driving a risk-based, automation-first quality approach across test strategy, design, execution, and continuous validation through CI/CD pipelines. The role is accountable for building and evolving scalable automation systems, improving release confidence, and ensuring quality signals are accurate and trusted by engineering and product teams.

It also involves ownership of automation architecture, defect prevention, release readiness, and CI/CD-integrated validation, while collaborating cross-functionally to improve system testability and embed quality early in the development lifecycle. Additionally, the role contributes to QE maturity by mentoring engineers and adopting modern practices such as AI-assisted testing and intelligent automation.
