Senior Software Development Engineer in Test

The Senior SDET will work closely with engineering, product, architecture, DevOps/SRE, security, and delivery teams to embed quality earlier in the development process. The role will establish effective automated quality gates, transfer vendor-managed automation into sustainable in-house ownership, and provide fast, risk-based confidence in releases during system migrations, refactoring, and platform modernisation.

Accountabilities

• Take ownership of existing vendor-managed test automation and establish clear standards for quality, governance, documentation, CI integration, reliability, and maintainability.

• Improve the coverage, reliability, and efficiency of automated testing across web, mobile, and backend platforms.

• Enhance release quality to deliver a better user experience and improve customer satisfaction.

Responsibilities

• Work with developers to design and implement tests at the appropriate level of the test pyramid or testing trophy. This includes unit, component, contract, API, integration, end-to-end, visual, and accessibility testing.

• Set up automated quality gates throughout the software development lifecycle so that issues are identified as early as possible.

• Define and track test automation metrics to support continuous improvement and accountability.

• Continuously improve the coverage, reliability, and efficiency of test automation.

• Use AI agents and coding assistants responsibly to support test planning, requirements analysis, risk identification, test design, automation development, test data generation, failure investigation, coverage-gap analysis, documentation, and code refactoring.

• Develop internal tools, libraries, and platforms that make quality practices more accessible to both engineering and non-engineering teams.

• Work with developers to improve system testability, observability, test-data setup, environment stability, and release confidence.

• Collaborate with engineering and Quality Engineering stakeholders to align test automation strategies, standards, and objectives.

• Work with vendors to ensure automation solutions meet the organisation’s required standards.

• Produce clear technical documentation, including RFCs, test plans, READMEs, onboarding guides, and quality playbooks.

Ideal Track Record

• Delivered automated unit, integration, and end-to-end tests covering critical user journeys and system behaviours, reducing regression testing time from days to hours.

• Designed or made significant contributions to automated testing frameworks built from the ground up, with measurable improvements in testing efficiency.

• Created dashboards to report test automation performance and metrics to stakeholders.

• Integrated automated tests into CI/CD pipelines.

• Used AI coding assistants or agents, such as GitHub Copilot, Claude Code, Codex, or similar tools, for testing, automation, documentation, failure investigation, or quality analysis.

• Managed test environments and automation infrastructure using cloud-based services such as AWS, GCP, BrowserStack, or LambdaTest.

• Developed internal testing tools and utilities that made Quality Engineering practices easier to use and improved productivity for both engineering and non-engineering teams.
