Test jobs in United Kingdom

We are looking for a Senior Software Engineer in Test to join our Liberty Blume team in Bradford (BD4) initially on a 12month FTC. This hybrid position requires at least two days per week in the office.

As part of our Technology and Product Development team, you’ll take ownership of our automated testing strategy across a modern tech stack that includes a Python-based backend, PostgreSQL databases, and a React frontend. You’ll be responsible for designing, building, and maintaining comprehensive end-to-end test suites that enable fast, reliable releases—minimising the need for manual UAT and helping us accelerate our delivery pipeline.

What will you be doing?

• Define and lead the end-to-end testing strategy for both new and existing applications built on our Python, PostgreSQL, React, and GCP-based tech stack.
• Select, configure and maintain automated testing frameworks (e.g., pytest, Selenium/WebDriver, Playwright, Cypress) that align with our architecture and goals.
• Design and develop robust automated test suites covering API, integration, UI, database, and regression testing scenarios.
• Build and manage CI/CD test pipelines (e.g., GitHub Actions, Jenkins) to ensure automated tests run on every pull request and deployment.
• Collaborate closely with engineers and stakeholders to embed testing early in the development lifecycle and provide rapid feedback loops.
• Create and maintain test plans, acceptance criteria, and traceability matrices to ensure comprehensive coverage and documentation.
• Investigate and resolve test failures or flaky tests, working alongside developers to identify root causes and implement fixes.
• Take full ownership of the testing function as the initial sole tester—planning, executing, and reporting—while laying the groundwork for a scalable testing practice.
• Support and mentor junior engineers or future QA hires as the testing team grows.

We tend to look for people with:

Essential

• Proven experiencein designing and implementing automated testing solutions for modern web applications.
• Proficient in Python, with the ability to write clean, reusable test libraries and utility functions.
• Hands-on experiencewith frontend test automation using JavaScript/TypeScript and frameworks such as Cypress, Playwright, or Selenium, particularly in React environments.
• Familiarity with relational databases (e.g., PostgreSQL), including the ability to create test fixtures and mock data for complex scenarios.
• Knowledgeable in CI/CD practices, with experience integrating automated test suites into build pipelines using tools like GitHub Actions or Jenkins.
• Skilled in defining and executingcomprehensive end-to-end testing strategies, covering API, integration, UI, and regression testing.
• Self-starter mindset, comfortable operating as the sole tester—proactive, independent, and capable of establishing testing processes from the ground up.
• Excellent communicator, able to clearly convey testing progress, risks, and outcomes to technical and non-technical stakeholders.

Desirable

• Prior experiencein establishing or scaling a software testing function or team.
• Working knowledge of containerisation toolslike Docker to spin up test environments.
• Familiarity with performance and load testing tools, such as Locust or JMeter.
• Exposure to cloud platforms, particularly Google Cloud Platform (GCP).
• Understanding of security testing principles, including best practices outlined by OWASP.
• Relevant certificationsin software testing or quality assurance (e.g., ISTQB or equivalent).
