This role offers you the opportunity to work at the forefront of AI-driven quality assurance, where your judgment, curiosity, and clear communication are valued above a perfect CV. You will be empowered to direct AI agents for test planning, code generation, failure triage, and code review, ensuring that your expertise guides the process where machines cannot be trusted. Enjoy mentoring from senior SDETs, genuine ownership from day one, and a clear path into product development if desired. The organisation is committed to diversity and inclusion, providing an environment where every voice matters and flexible working opportunities are available. If you are passionate about AI-assisted engineering and want to develop a skill set few QA engineers possess, this is your chance to make a meaningful impact.

• Work alongside agentic AI tools daily, directing them for test planning, code generation, and failure triage while critically verifying outputs before deployment.
• Receive mentoring from experienced SDETs and enjoy real ownership early in your career with opportunities for growth into product development roles.
• Join a globally distributed team in a regulated environment that values diversity, inclusion, and flexible working arrangements for all employees.

What youll do:

As a Software Development Engineer in Test AI-Driven Testing, you will immerse yourself in an innovative QA environment where agentic AI tools handle much of the mechanical work. Your primary focus will be on tasks requiring human insight: deciding whats worth testing, validating generated tests for genuine failure scenarios, identifying misleading passing suites, and distinguishing between product bugs and environmental issues. Youll author robust automated UI and API tests using Playwright and TypeScript across various platform surfaces. Daily responsibilities include directing AI agents for test planning and code generation while maintaining critical oversight over their outputs. Youll triage regression runs with precisionfiling actionable bug reportsand uphold suite honesty by linking failures to known issues. Maintaining CI pipelines via GitHub Actions ensures reliability across releases. Occasionally youll step into development territory to fix minor bugs directly within the monorepo. Peer reviews are youll both give and receive evidence-based feedback on test PRs. Collaboration is key as you connect with colleagues worldwide to share knowledge and nurture a supportive network.

• Author and maintain automated UI and API tests using Playwright and TypeScript to cover trading, custody, and customer portal surfaces of the platform.
• Direct agentic AI tools for planning tests, generating code, triaging failures, reviewing pull requests, and ensure all outputs are thoroughly verified before shipping.
• Triage nightly regression and smoke runs by separating genuine product bugs from environmental noise or test-side file clear bug reports that developers can act on.
• Ensure the integrity of the test suite by linking failing tests to known bugs, releasing them when fixes land, and preventing silent skips or warnings from hiding real defects.
• Run and maintain suites in continuous integration environments such as GitHub A help keep pipelines green, fast, and trustworthy.
• Maintain traceability of test cases within test-case-management tooling to ensure comprehensive coverage and accountability.
• Occasionally cross the boundary between testing and development by fixing small bugs or making improvements directly within the monorepo through standard PR processes.
• Review teammates test pull requests and respond constructively to review findingsincluding those raised by AI reviewerswith evidence-based feedback.
• Collaborate closely with developers, QA engineers, and product owners across a globally distributed team to foster shared understanding and communal problem-solving.

What you bring:

Your proven experience as a Software Development Engineer in Test AI-Driven Testing will demonstrate hands-on involvement in software testing or QA automation within complex environments. You bring technical proficiency with JavaScript/TypeScriptor show adaptability in learning new languages rapidlypaired with deep knowledge of web applications and HTTP APIs. Your enthusiasm for AI-assisted workflows means youre comfortable delegating tasks to intelligent agents yet remain vigilant about their output quality. Clear written communication is you excel at drafting precise bug reports and review comments that facilitate communal understanding among global teams. Attention to detail ensures honest reporting of failures rather than masking defects behind false positives. Experience with Playwright or similar frameworks strengthens your candidacy while familiarity with financial services concepts or digital assets provides additional context for platform-specific challenges. Skills in real-time data processing (WebSockets), database management (SQL/PostgreSQL), CI pipeline maintenance (GitHub Actions), or performance testing further enhance your profile. Above all else, your collaborative spirit enables you to thrive within diverse teams dedicated to nurturing each others growth.

• Hands-on experience in software testing, QA automation or software developmenttypically 36 years though flexibility exists for exceptional candidates.
• Working knowledge of JavaScript or TypeScriptor demonstrable ability to quickly learn new programming languages as needed.
• Solid understanding of web applications and HTTP APIs including requests/responses, status codes, JSON formatting, authentication mechanisms.
• Genuine interest in AI-assisted comfortable leveraging AI tools for real tasks while maintaining healthy scepticism about their outputs.
• Excellent written English clarity in prompts, bug reports, test plans, and review comments is essential for success in an agentic workflow.
• Meticulous attention to detail coupled with honest transparent explanations of failing tests are highly valued over unexplained successes.
• Experience with Playwright (or Cypress/Selenium) is advantageous but not mandatory.
• Background building or maintaining shared test frameworkssuch as fixtures, page objects or CI wiringis beneficial beyond writing specs alone.
• Exposure to financial services or capital marketsincluding order lifecycles, settlement processes or custody conceptsis helpful but not required.
• Familiarity with WebSockets/real-time data handling, SQL/PostgreSQL databases or CI pipelines like GitHub Actions adds value to your application.
• Understanding of digital assets or blockchain technologies is considered a plus.
• Performance or load testing experience (using k6/JMeter or similar) is nice-to-have but not essential.
