About the Role

We're looking for a Senior Software Engineer who cares deeply about building high-quality products - not just testing them after the fact. In this role, you'll help shape how quality is engineered into our products from day one, working across software development, automation, and modern testing practices. This role includes a blend of hands-on testing and automation. You'll design systems, build tooling, and dive into manual testing where it adds the most value - all while helping the team deliver reliable software at scale. We're exploring how AI can meaningfully improve quality engineering beyond code assistants, and you'll have the opportunity to shape that journey in a practical, grounded way. This is an area we're actively evolving, not a fully mature capability today. If you enjoy solving real engineering problems, improving how teams build software, and taking a pragmatic approach to quality, this role will give you the space to do it.

What You Will Do

• Engineering Quality into the Product: Partner with engineers, product managers, and designers to build quality into features from the start - not bolt it on at the end. Contribute directly to product code where it improves reliability, testability, and observability. Help shape system design decisions to reduce defects before they happen.
• Building Scalable Test
