Sr. UI Platform Engineer

Salary: £65,000 - 105,000 per year

Requirements:

• We have built shared frameworks, tooling or platforms that other engineers rely on day to day.
• We know Playwright well for browser end-to-end testing and are comfortable with unit and component testing, such as Vitest or similar, and visual regression.
• We are fluent in TypeScript, Vite and modern front-end tooling.
• We have designed GitLab CI pipelines that stay fast and reliable and give engineers a clear signal when something breaks.
• We have set engineering standards that autonomous teams have genuinely adopted and can influence senior engineers and leaders when it matters.
• We have used AI in earnest to change how engineering work gets done, not as a novelty.
• We have proven experience utilizing AI technologies to enhance decision-making, streamline workflows and processes, improve efficiency and drive business outcomes.

Responsibilities:

• Lead the shared UI testing framework that every Product Group uses, from unit and component tests through to end-to-end and visual regression.
• Design and run the CI pipelines that gate every UI release across GitLab CI and Jenkins, keeping them fast, reliable and honest about failures.
• Ship the UI Quality Score as a public signal that brings together coverage, escaped defects, skipped tests, incident data and dependency health.
• Wire automated dependency management, security testing and AI-assisted test authorship into the paved road so upgrades, vulnerability response and quality work do not fall on individual teams.
• Work with UI Developer Tooling, UI Release and Observability so the platform feels like one thing through a single CLI.
• Pair with Product Group leads to move legacy testing patterns onto the paved road and get the testing strategy adopted across the organisation.
• Mentor engineers on testing practice and quality patterns and give thoughtful code review across the platform and its consumers.
• Build the quarantine and triage system for flaky tests so intermittent failures stop blocking releases and get fixed rather than ignored.
