Role: Automated Test Developer / SDET

We are looking for an experienced Automated Test Developer / SDET to join the QA team. The successful candidate will maintain and extend an enterprise-grade.NET test automation framework built on Reqnroll (BDD) and Microsoft Playwright on.NET 8. The role sits within a cross-functional delivery team working on the Microsoft Dynamics 365-based application for council tax property assessment. The candidate will work closely with Functional Testers, developers, BAs, and DevOps engineers to embed automated testing into the CI/CD pipeline and shift testing left across the delivery lifecycle.

Key Responsibilities

  • Maintain and extend the Reqnroll (SpecFlow) BDD automation framework written in C# /.NET 8 using Microsoft Playwright
  • Write and review Gherkin feature files, step definitions, and page objects to support new and changed functionality
  • Ensure automated tests are submitted alongside pull requests for new features - contributing to a shift-left testing model
  • Investigate and resolve test flakiness - replacing hard sleeps with condition-based waits, standardising step definitions, eliminating duplicate bindings
  • Maintain and improve the Azure DevOps CI/CD pipeline - test result publishing, environment switching, and PR gate configuration
  • Triage pipeline failures and distinguish test failures from environment or infrastructure issues
  • Work with the DevOps team to configure and maintain the agent pool
  • Manage test data in Excel and database - ensuring data integrity and environment isolation between SIT, UAT, and FAT
  • Participate in sprint ceremonies - providing test estimates, flagging automation risk, and contributing to Definition of Done
  • Mentor junior QA team members on framework usage, Gherkin best practices, and Playwright
  • Contribute to the Ways of Working improvement programme - defining PR gate criteria and embedding tests into the delivery pipeline

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

Start with a chat, not a search bar

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
