We are looking for a Senior Software Engineer in Test to join our Liberty Blume team in Bradford (BD4) initially on a 12-month 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 manual UAT and helping us accelerate our delivery pipeline.

What will you be doing?

• Define and lead the end-to-end testing strategy for 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).
• 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 with engineers and stakeholders to embed testing early in the development lifecycle and provide rapid feedback.
• Create and maintain test plans, acceptance criteria, and traceability matrices for comprehensive coverage and documentation.
• Investigate and resolve test failures or flaky tests, working with developers to identify root causes and fixes.
• Take 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.

What we look for:

• Proven experience in designing and implementing automated testing solutions for modern web applications.
• Proficient in Python, able to write clean, reusable test libraries and utilities.
• Familiarity with relational databases (e.g., PostgreSQL), including creating test fixtures and mock data.
• Knowledge of CI/CD practices, integrating automated tests into build pipelines using tools like GitHub Actions or Jenkins.
• Experience defining and executing comprehensive end-to-end testing strategies, including API, UI, and regression testing.
• Self-starter, proactive, independent, capable of establishing testing processes from scratch.
• Excellent communication skills, able to convey testing progress, risks, and outcomes clearly.
• Experience in establishing or scaling a testing team or function.
• Knowledge of containerisation tools like Docker for test environments.
• Familiarity with performance and load testing tools such as Locust or JMeter.
• Experience with cloud platforms, especially GCP.
• Understanding of security testing principles, including OWASP best practices.
• Relevant certifications (e.g., ISTQB) are a plus.

What’s in it for you?

• Competitive salary + bonus
• 25 days annual leave, with options to purchase 5 more
• Wellbeing and mental health benefits (Calm app, medical, critical illness, dental)
• Matched pension contributions up to 10%
• Car benefit scheme
• Access to online learning platform for career development
• Join an innovative, fast-paced, passionate team
