What you'll do

• Ship Features, Not Just Code: You will build well-scoped features from first commit to production. You won’t just write functions in isolation; you will check that your code solves the actual user problem, works in production, and is covered by solid tests.
• Collaborate to Raise the Bar: You will work closely with teammates across Identity and adjacent teams, and learn from them. You will take part in code reviews and design discussions, and follow and help improve our shared standards. You ask for help early, and you speak up with questions or ideas when you think there is a better way.
• Leverage Modern Tooling: You will use AI-assisted tools (like Copilot and Claude) to handle boilerplate and refactoring, allowing you to focus on logic and product value. We value engineers who use the best tools to ship faster.
• Build for Quality: You will write well-tested, production-ready code that your team (and your future self) will thank you for. You understand that “speed” doesn’t mean “sloppy”-it means building reliable software that doesn’t break at 2am. You will participate in incident response, learn from postmortems, and help the team raise the bar on code quality and operational health.

Qualities we look for

• Ownership and Reliability: You take responsibility for what you ship. You write tests, monitor your code in production, and follow through when things go wrong. You’re proactive about flagging issues and asking for help when you need it, and you treat each incident as an opportunity to learn.
• Strong Engineering Fundamentals: You have a solid grasp of data structures, algorithms, and clean coding principles. You can take a complex logic problem and break it down into small, solvable pieces. You are curious about what it takes to build and operate reliable, high throughput services, and keen to learn this hands‑on.
• Adaptability: You have a good foundation in backend development and server‑side systems. Our stack relies on C#/.NET Core, Cassandra, gRPC, and Kubernetes. We don’t expect you to be an expert in all of them today, but we expect you to be willing to jump in and learn whatever tool gets the job done.
• Enterprise Domain Curiosity: You are interested in the hard problems of B2B SaaS Identity – authentication (SSO/OIDC), authorization, and requirements such as security and auditing. You understand that these aren’t “boring details”; they are the pillars of trust for enterprise clients.
• AI-Native Velocity: You leverage AI-powered tools (like GitHub Copilot or Claude) to accelerate your velocity and eliminate repetitive toil. You use AI for boilerplate code, test generation, and debugging, allowing you to focus your cognitive energy on high-value architectural decisions and complex problem-solving.
