This is a hands-on technical leadership role. You will design and build automated compliance validation frameworks, define and evolve compliance testing strategies, and integrate quality deeply into our development lifecycle.

- Continuously improve compliance testing processes, tooling, and quality metrics.

Required Qualifications:

- Strong programming skills in C# and Python.
- Proven experience designing and maintaining test automation frameworks.
- Hands-on experience with compliance testing (e.g. data retention, auditability, regulatory validation).
- Strong background in white-box testing of APIs, services, and system internals.
- Solid understanding of cloud platforms (AWS/GCP) and containerized environments (Kubernetes).
- Experience working with CI/CD pipelines, Git, and modern testing tools.
- Familiarity with Windows 10/11 environments.
- Strong understanding of software development practices and modern testing methodologies.

Soft Skills

- Proven ability to lead and influence compliance-focused quality initiatives.
- Excellent communication and collaboration skills across engineering, product, and security teams.
- Strong analytical mindset with attention to detail and risk awareness.
- Comfortable working in a fast-paced, cross-functional environment.
- Proactive, self-driven, and deeply invested in quality and regulatory excellence.

Education & Experience

- Bachelor’s or Master’s degree in Computer Science, Software Engineering, or equivalent practical experience.
- 5+ years of experience in QA or SDET roles, with a strong focus on compliance and quality.
- 2+ years in a senior or lead role, driving quality or compliance initiatives at scale.

## Why This Role Matters
