• Client Interfacing: Devote a small portion of your time to providing external testing support and guidance to global clients and third-party vendors.

What We Are Looking For

• Financial Markets Expertise: Demonstrable experience testing complex financial market software solutions, specifically within Cash Equities or related trading environments.
• Automation Tech Stack: Strong proficiency in JavaScript/TypeScript with hands-on experience building E2E frameworks via Playwright.
• Technical Foundations: Robust experience navigating Unix/Linux environments and querying relational databases using SQL.
• Mindset: A methodical, self-starting professional who thrives under pressure, takes full ownership of tasks, and possesses sharp problem-solving capabilities.

Desirable Skills (Bonus Points)

• ISEB/ISTQB Foundation Certification.
• Experience with Containers (Docker) and integrating tests into CI/CD pipelines.
• Familiarity with financial regulations, reporting rules, or asset classes like Derivatives, Asset Management, and Bonds.

You will join a vibrant, close-knit team where your ideas are genuinely encouraged. Our client offers a workplace that actively champions positive disruption, celebrates collective success, and empowers individuals to make a tangible impact on the future of financial technology.
