Job summary

CrowdStrike is seeking a Senior Software Engineer - UI Platform to design and build the shared quality foundation for our next-generation front end. This role shapes how hundreds of UI engineers ship, test and operate their code across the organisation.

You will own the UI testing framework, CI pipelines, and quality signals, mentor engineers, and collaborate with Product Groups to move legacy testing patterns to the paved road. Hybrid work model with strong growth in a mission-driven company.

Qualifications

• You've built shared frameworks, tooling or platforms that other engineers rely on day to day.

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 don't 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.
