Senior QA Engineer

We are looking for a Senior QA Engineer to join our Engineering capability who will be responsible for designing, developing, and maintaining high-quality automated testing solutions. You will work on complex automation projects, contributing to the architecture, implementation, and improvement of automated test frameworks across UI, API, and database systems. This role involves mentoring other QA engineers, collaborating with cross-functional teams, and driving the adoption of best practices in automated software testing to ensure reliable and efficient product delivery.

Responsibilities

• Leads the development of test approaches for major projects, providing risk-based guidance and advising on modern functional testing techniques.
• Develops and maintains complex automated scripts for UI, API, and database systems, ensuring high performance, reliability, and adherence to standards.
• Works with the squad to identify and assess non-functional quality characteristics (e.g., performance, security), advocating for appropriate testing approaches.
• Investigates existing testing processes to identify inefficiencies and drives data-backed recommendations for improvement.
• Owns the end-to-end testing lifecycle for specific squads, critically evaluating findings and communicating quality insights to the wider team.
• Maintains automated tests within CI/CD pipelines, troubleshooting failures to ensure rapid and actionable feedback for developers.
• Peer-reviews the work of other QA engineers and provides daily technical coaching to improve team automation capabilities.
• Partners with developers during refinement and planning to advocate for early engagement, identifying testability gaps and ensuring requirements are clearly defined before development begins.
• Researches emerging tools and frameworks to stay current with industry trends and trains others to improve testing efficiency.

About You

Professional knowledge and experience

Essential

• Expert proficiency in implementing and extending robust automated testing solutions using modern frameworks—such as Playwright, Selenium, or Cypress—and established patterns (e.g., POM or Data-Driven) to ensure comprehensive feature coverage and clean, maintainable code.
• Deep practical knowledge of industry-standard tools for web, API, and mobile testing, with the ability to troubleshoot complex environment-specific issues.
• Hands-on experience integrating and managing automated tests within CI/CD pipelines to ensure rapid and reliable feedback for development squads.
• Ability to translate complex user needs and business requirements into detailed test plans and automation scripts, ensuring maximum ROI through targeted test selection.
• Strong SQL skills for database validation and familiarity with scripting (UNIX/Shell/PowerShell) to automate repetitive setup tasks.
• Experience taking ownership of the QA lifecycle within a delivery team, including the mentorship of junior engineers and the promotion of best practices.

Desirable

• Previous experience in a consultancy or central government environment is highly advantageous.
• Proven ability to work across multiple programming languages and to quickly adapt to new technical stacks.
• Experience with Ruby and using Ruby-based automation frameworks, including Capybara, to design and maintain robust end-to-end test suites.
• Prior experience in Non-Functional Testing (NFT) is a plus.
• Previous experience owning the quality strategy for a high-priority delivery squad.

Technical skills

• Ability to implement test framework components that meet the specific business and technical requirements of a given feature or product area.
• Proven ability to research and devise new testing techniques and tools, providing recommendations to the team to improve overall testing efficiency.
• Expertise in writing clean, well-documented, and reusable code.
• Expertise in reviewing peer code to ensure accuracy, adherence to standards, and effective bug detection.
• Proficiency in setting up, managing, and troubleshooting automation execution within CI/CD pipelines.
• A structured and proficient approach to API testing using both automated code frameworks and exploratory tools like Postman.

Behaviours

• Analytical Thinking & Problem-Solving: Applies critical thinking to prioritize high-value test cases within a sprint, ensuring automation efforts are targeted where they provide the most immediate benefit to the delivery team. Resolves complex technical issues, such as flaky tests, environment dependencies, or intricate script logic, to maintain a reliable and performant automation suite.
• Strategic Communication: Effectively communicates technical risks, defect trends, and comprehensive test strategies to stakeholders, ensuring quality concerns are addressed early in the delivery lifecycle. Acts as a collaborative bridge within the squad, facilitating discussions with the team to improve the "testability" of new features and clarify requirements.
• Mentoring & Leadership: Provides consistent coaching and hands-on support to junior engineers, helping them master automation best practices, clean code principles, and framework usage. Drives high standards of quality within the team by conducting rigorous code reviews and encouraging the professional growth of peers through knowledge sharing.
• Adaptability & Risk Management: Navigates changing sprint requirements with agility, quickly adjusting automation plans to align with shifting priorities without compromising on quality standards. Identifies potential feature-level risks early in the development lifecycle and proactively suggests mitigation strategies to the delivery team.

Strengths, drivers and traits

• Continuous Improvement Advocate: Driven by a desire to find inefficiencies in testing processes and providing data-backed recommendations for improvement.
• Quality-First Mindset: Committed to professional integrity and ensuring "Definition of Done" is met across all project deliverables.
