Who We Are

Thanks to our Omaze Community, we’ve raised over £100 million for UK charities in just five years. That’s millions helping organisations like Age UK, the RSPCA, British Heart Foundation and Great Ormond Street Hospital Charity deliver life-saving work.

And the best part? We’re only just getting started. Omaze is building a business and culture committed to growth and creating significant social impact on a global scale.

About The Job

As a Senior Software Developer In Test (SDET) at Omaze, you take genuine ownership of quality, not as a gate at the end of the development process, but as something that's built in from the start. You're experienced across the testing spectrum, from designing and scaling test automation frameworks to exploratory testing and quality advocacy. You know how to bring engineers, product managers, and designers along with you. You care about craft and rigour, but you're equally focused on outcomes and appreciate that fast, confident releases let us keep delivering for the charities that depend on our platform.

What You’ll Do

• Own the Quality Engineering and test automation strategy for Omaze by designing, implementing, and evolving it as the team and product grow.

• Champion a shift-left approach to quality, embedding automated testing practices throughout the development lifecycle so issues are caught early, not downstream.

• Build scalable, maintainable automation frameworks that reduce repetitive manual testing and enable high-confidence, fast releases.

• Define and track quality metrics. Use defect escape rate, test coverage, cycle time metrics (amongst others) to drive meaningful, continuous improvement.

• Influence engineers, product managers, and designers to take genuine shared ownership of quality, not treat it as someone else's responsibility.

• Evaluate and introduce tooling and frameworks that improve coverage, reliability, and developer experience across the testing stack.

• Mentor QA engineers and advocate for quality practices across the broader engineering team.

• Use AI-assisted testing tools as a natural part of your workflow, applying the same rigour and judgement to AI-generated test coverage as you would to anything hand written.

About You

• Significant experience as a Quality Engineer or SDET with a strong focus on test automation at scale.

• Proven track record defining and scaling Quality Engineering processes within a growing engineering organisation.

• Strong experience building maintainable, scalable automation frameworks. Hands-on experience with tools such as Cypress, Playwright, and/or Appium.

• Experience with performance and load testing tools (e.g. K6, JMeter, Gatling).

• Comfortable working across CI/CD pipelines (e.g. GitHub Actions, CircleCI) and continuous deployment practices.

• Experience in mobile app testing with tools like Appium or Maestro is beneficial.

• Experience with contract testing tools like Pact is beneficial.

• Experienced working in Agile environments and familiar with test management tooling.

• Knowledge of security and accessibility testing practices.

• Prior mentoring or leadership experience within QA or test automation; you're comfortable influencing teams beyond your immediate scope.

• A clear, confident communicator who can make the case for quality investment to technical and non-technical audiences alike

What’s In It For You

• Generous stock options scheme

• Private medical and dental insurance

• 9% employer pension contributions, when you contribute at least 2%

• A personal learning and development budget each year to use on training courses, conferences and professional memberships

• Personal equipment budget to work from home

• Enhanced family leave policies

• Life assurance of 4x your salary
