Job description

Bristol, Bulgaria, Cirencester, Portugal

Ref 106215 Department Technology Location Bristol, Bulgaria, Cirencester, Portugal Country UK Salary Competitive Closing date 03/12/2026

At Kallidus, we prove our client's teams are compliant, skilled, and high-performing. Trusted by over 1,000 organisations worldwide and proud to be a Certified B Corporation, we help organisations escape The Activity Trap: measuring learning by completion rather than real performance change.

Our award-winning learning and employee development platform has an intentional AI data layer to make learning, skills, and performance data valuable for the whole business. This helps link L&D initiatives to the goals and objectives of entire organisations and their teams. Our mission is to be the first company to measurably close the development gap, upskilling and reskilling over 100 million people worldwide.

We don’t just use technology, we build it. Our platform is designed and developed in-house, including Kallidus intelligence (K.i), the AI that turns learning, skills and performance data into insight leaders can act on. Because we own it end to end, the people leading that work have a genuine say in where it goes next.

As part of our continued expansion, Kallidus is creating a new Portugal Hub to execute our newAI initiative - Kallidus Intelligence K.I . We invite you to be part of that journey.

The Role

We're looking for a QA Automation Engineer who writes code, not just test cases. You'll build automated tests in C# using .NET, write behaviour-driven development (BDD) scenarios in Gherkin, and work inside the codebase alongside developers on unit tests as well as end-to-end coverage.

You’ll own quality across the whole test pyramid, from unit level up to the user interface, so defects are caught long before they reach our customers.

What you’ll do

• Write and maintain automated tests in C# using .NET test framework
• Write unit tests alongside developers, not only end-to-end tests
• Turn requirements into behaviour-driven scenarios in Gherkin and automate them with Cucumber
• Build and run automated user interface, API and functional tests for our web applications
• Plan test strategy with development and product teams, and design test plans and cases
• Maintain and improve our continuous integration (CI) pipelines so tests run reliably on every change
• Investigate failures, troubleshoot issues in systems under test, and work with developers on fixes
• Document test results and defects clearly
• Run post-release testing
• Use AI tools to speed up your work and improve code and documentation, while critically reviewing what they produce

What you’ll need

Essential

• Experience in a QA Automation or Software Development Engineer in Test (SDET) role
• Strong, hands-on C# and .NET; you're comfortable working in a production codebase
• Experience writing unit tests (for example xUnit, NUnit or MSTest), not only end-to-end tests
• Hands-on experience with Cucumber and/or Gherkin
• Experience testing web applications, including user interface and API testing
• Experience with continuous integration pipelines (for example Jenkins or Azure DevOps) and Git
• A degree in Computer Science, Engineering or a related field, or equivalent practical experience
• An analytical mind and a keen eye for detail

Nice to have

• Knowledge of Kubernetes and microservices architecture
• Experience with SpecFlow or Reqnroll
• Exposure to security or penetration testing
• Experience supporting applications in production

What we offer

• 27 days of annual leave
• Private health insurance
• Annual bonus opportunity
• Full tech setup
• Birthday Off
• Volunteering Day
• Support for your ongoing growth & development
• Enhanced Family Leave
• Flexible, hybrid approach to work
• Annual Company party
