ABOUT TAXCALC
TaxCalc is award-winning, HMRC-recognised and MTD-ready accounting software, trusted by more than 12,000 UK accounting firms.

MAIN PURPOSE OF ROLE
We are a SaaS business scaling at pace, and we are looking for an Automation Test Engineer who is judged on outcomes rather than activity. This role sits at the heart of Engager: you will work closely with the Engager team, taking ownership of Playwright-based automation testing across its front-end screens and API layers, and working with developers and product owners to make sure every release of the web app is reliable, secure and of high quality. You will operate within a close-knit team that places quality assurance at the centre of how we work, and will play a part in embedding these practices across the wider business.
EMPLOYMENT DETAILS
Location: Fully remote. Candidates must be living in Poland.
Contract: Full-time, B2B contract only.
Languages: Bilingual in English (B2+) and Polish (B2+), as you will be working closely with our Polish team.
Pay range: 2,500–2,800 GBP per month.
AI tools: Access to Claude and Claude Code is provided.
KEY RESPONSIBILITIES
Developing and maintaining Playwright automation frameworks and test suites (TypeScript/JavaScript) covering SaaS front-end screens and API endpoints.
Selecting and applying appropriate test automation tools and patterns for Playwright, including data-driven testing, page object models, and reusable API test helpers.
Participating in the change control process to assess the quality implications of known defects and the impact of proposed changes on the testing process.
Working with the DevOps team to build and maintain an automated build verification ("smoke") test, and integrating Playwright test suites into CI/CD pipelines.
Developing and executing automated Playwright test suites covering front-end screens (UI flows, regression, cross-browser) and API automation (REST/GraphQL) using TypeScript.
Using AI tools to speed up test creation and maintenance, such as generating and refactoring Playwright tests, building test data, and analysing failures, while reviewing all AI-generated output for accuracy and quality.
Acting as an advocate for quality throughout the development process.
Investigating and analysing issues within the test environment and applications under test.
Analysing test results and reporting findings clearly to the wider team.
Prioritising testing and project work in line with agreed business priorities.
Undertaking other testing-related duties as required.
QUALIFICATIONS & EXPERIENCE
A degree in Computer Science or a related discipline, an ISEB/ISTQB qualification, or equivalent professional/commercial experience.
At least 3 years' hands-on experience in front-end web automation using Playwright with TypeScript/JavaScript, testing SaaS applications.
Experience planning and estimating test activity, and collaborating with product owners, business analysts, and developers.
Fluent written and spoken English (B2+) and Polish (B2+).
KEY TECHNICAL SKILLS
Highly experienced working in an agile development environment.
Extensive hands-on experience with Playwright for front-end web automation of SaaS applications (cross-browser UI testing, page object models, visual/regression testing); familiarity with Selenium or similar tools is an advantage.
Experience with test management tools such as Quality Center or Zephyr is an advantage.
Strong experience with TypeScript/JavaScript for Playwright automation, together with API test automation experience (REST/GraphQL) using tools such as Playwright's API testing capabilities or Postman; scripting experience with Bash is an advantage.

An analytical and organised approach to problem solving, with strong attention to detail.
