Senior Software Engineer in Test (SDET)

New Yesterday

Senior Software Engineer in Test (Senior SDET) – Department: Omnichannel Experience (OCX). We offer hybrid working, with occasional presence at one of our Holland & Barrett offices in London or Nuneaton for team collaboration, key meetings and events (typically once per quarter). About The Role We’re looking for a Senior Software Engineer in Test (SDET) to help shape and elevate quality engineering across our Omnichannel Experience (OCX) domain. This role goes beyond traditional testing. You’ll play a key part in improving how we think about quality across multiple teams, introducing better practices, strengthening automation, and enabling teams to deliver high‑quality software with confidence. What you’ll be doing
Lead and evolve quality engineering practices across multiple product teams. Design, build and improve automated testing frameworks (UI, API and service‑level). Expand testing strategies beyond end‑to‑end into microservices and system‑level validation. Drive a shift‑left approach to quality, embedding testing earlier in the development lifecycle. Contribute to CI/CD pipelines, ensuring quality is integrated into delivery workflows. Improve observability and monitoring to support proactive quality and faster issue resolution. Partner with engineers, product and QA to define and implement best practices. Identify and remove blockers, enabling teams to deliver efficiently. Influence and guide teams on modern testing approaches and tooling.
What you’ll bring
Strong experience in software testing and quality engineering within modern engineering environments. Proven experience building and owning automation frameworks from scratch. Strong coding skills (e.g., Java, Kotlin, JavaScript or similar). Experience testing across multiple layers – UI, API, and microservices. Practical experience with CI/CD pipelines and integrating automated testing into delivery. Experience working with distributed systems and modern architectures. A strong understanding of quality beyond functional testing (e.g., performance, resilience, observability). Experience influencing and driving initiatives across multiple teams. A proactive, problem‑solving mindset with the ability to unblock others.
Ways of working
Agile environment (continuously evolving and improving). Fully remote working supported, with optional office collaboration. Flexibility in working hours, aligned broadly to UK time zones.
What success looks like
Teams adopt stronger, more consistent quality engineering practices. Automation is scalable, reliable and embedded across the development lifecycle. Quality is considered early, not just at the end of delivery. Engineers are empowered with better tools, frameworks and guidance. Delivery is faster, more stable and more predictable.
Key considerations (screening focus)
Demonstrated technical leadership (without relying on people management). Experience building and evolving automation frameworks. Evidence of improving quality beyond traditional E2E/API testing. Balanced automation approach (not manual‑heavy). Experience influencing multiple teams and driving change.
