Senior Software Development Engineer in Test

An innovative tech-for-good company in the UK are on a mission to grow their engineering hub in Edinburgh, as they look to bring in an experienced Senior SDIT to their hybrid team. They've been helping hundreds of thousands of people live more independently - and now they're investing big in automation, AI, and cloud tech to take things to the next level.

They've got offices in London, Bristol, and now Edinburgh - where they're building out a team of forward-thinking Software Engineers in Test. These roles are part of a wider shift from manual to automated testing, and it's a brilliant time to join as they ramp things up.

What's the job?

You'll be leading testing efforts across one or more product teams - helping define strategy, guiding best practices, and mentoring more junior SETs. You'll build out automated test frameworks from the ground up (think Playwright, Cypress, or similar), and work across the full stack - frontend, backend, and APIs.

There's also a strong DevOps and observability culture, so you'll get stuck into tooling like Dynatrace, Splunk, and OpsGenie, and help improve reliability and performance from the ground up.

This is a role for someone who wants to own the quality space and shape how testing is done across a growing engineering function.

You'll bring:

Strong experience with modern test automation tools (Playwright, Cypress)
API testing know-how (Postman, SOAPUi, etc.)
A solid understanding of CI/CD and DevOps practices
A product-first mindset with a real focus on quality and user experience
Mentoring or leadership experience
Confidence influencing testing strategy and tooling decisions
Strong communication - you'll be working cross-functionally every day

Bonus points for:

Programming skills (JavaScript/TypeScript, Java, or similar)
Previous experience in a scale-up or product-driven company
A passion for tech that makes a difference

You'll be in the Edinburgh office 3 days a week (flexible which ones), and you'll travel to Bristol or London every couple of months to catch up with the wider crew - fully paid, of course.

In return, they're able to offer a salary of between £55-70k, as well as a strong benefits package which includes a non-contributory pension of 15%, 28 days holiday, personal development and learning support, and more!

This is a genuinely rewarding opportunity with a growing organisation that's all about making a difference with technology. You'll be part of a team that values innovation, inclusion, and customer-first thinking.
