Technology at H&B
We're on a mission to make health and wellness a way of life for everyone and technology is at the heart of our future to become a leading omni-channel retailer. We're building some great products, and we're investing in the rapidly advancing technology that is helping our customers meet their health and wellness goals. We're delivering more speed in the retail experience, greater convenience in service and delivery, and increasing personalisation in our brand and product propositions, both in-store and online.
Collaborative, working at pace and always with a strong customer focus in everything we do. We love the cloud, we prefer building the right solutions over buying generic ones, and we embrace automation and testing in all things software, infrastructure, and data.
About the RoleWe're at an exciting moment in our engineering journey. As we modernise our platforms and ways of working, we're also re-introducing what good looks like for quality at Holland & Barrett.
We're moving from traditional testing approaches towards a modern, engineering-led quality strategy: unit testing, contract testing, component testing, integration testing, E2E flows, synthetics, and strong observability across our microservices.
We're looking for a Senior SDET who is hands-on, highly technical, and passionate about setting teams up for long-term success. In this role, you'll build the frameworks, tools, and practices that empower engineers to write and maintain their own tests with you acting as the subject-matter expert, coach, and quality advocate who helps them get there.
This is a high-impact role within our eCommerce Engineering organisation (web and mobile). You'll collaborate closely with engineers, designers and product teams to embed a test-first mindset and raise the bar for reliability, delivery confidence, and customer experience.
What you'll do
Design, build, and maintain scalable automation frameworks that are easy for engineers to use and extend.
Partner with teams to introduce modern microservices testing approaches across unit, contract, component, integration and E2E layers.
Lead the shift towards engineers owning their tests by providing guidance, examples, and hands-on pairing to help teams adopt best practices confidently.
Collaborate with Engineering and DevOps to evolve CI/CD pipelines and embed automation earlier in the lifecycle.
Improve observability around testing and reliability, integrating logs, traces, metrics, synthetics, and alerts to increase confidence in releases.
Promote good testing principles and high-quality engineering practices across teams; become a trusted voice for quality.
Act as a consultant-style partner to squads, helping them design testable systems and adopt pragmatic approaches to automation.
Support a culture where quality is shared by everyone, not a separate phase or team.
Demonstrate excellent attention to detail and help others develop the same discipline.
Key RequirementWhat you'll bring:
Essential:
Strong software engineering background in any language.
Proven experience building automation frameworks from scratch.
Solid understanding of microservice testing approaches: unit, contract, component, integration, and E2E.
Experience with tools such as Playwright, Cypress, JUnit, WireMock, or similar.
Strong CI/CD knowledge (GitLab CI, Jenkins, etc.) and familiarity with Infrastructure-as-Code and cloud-native environments (containers, Kubernetes).
Understanding of observability (Grafana, Datadog, Prometheus, OpenTelemetry, etc.) and how it supports quality and testing.
Ability to explain technical concepts clearly to different audiences.
A collaborative style, with experience driving culture change or elevating quality practices across multiple squads.
Nice to have:
Experience writing in JavaScript/TypeScript, Java, Kotlin or Go.
Experience with React Native test automation.
Experience testing AI/ML systems.
Exposure to building internal developer platforms or quality-focused tooling.
Experience in software engineering, SRE, DevOps, or developer experience teams.
Our tech stack:
Languages: JavaScript/TypeScript, Java/Kotlin Spring boot, Go
Frontend: React, React Native
Infrastructure: AWS, Kubernetes, GitLab CI/CD
Testing: Playwright, BrowserStack
Architecture: Microservices
