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 Dev Ops 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.
