You'll work on complex problems, design clean solutions, and build maintainable systems that stand up over time. You'll be working primarily in a .NET / C# environment, contributing to core services, shared components, and distributed systems.

Leadership is a nice-to-have, not an expectation. If you enjoy guiding others or leading a technical initiative, that's a bonus - but the role is designed for senior engineers who want to stay hands-on. If you care about engineering craft, autonomy, and solving problems properly, this role is worth a conversation.
