8. Mentor and support more junior engineers through coaching and feedback.

Who you are

1. 5+ years of experience building and scaling distributed systems, ideally serving millions of users.
2. Good knowledge in one or more JVM-based languages (ideally Kotlin with Micronaut).
3. Proven experience in DevOps practices, including running and operating what you build.
4. Experience designing CI/CD pipelines and driving improvements in developer productivity.
5. Comfortable working in cloud environments (preferably Azure).
6. Experience with standards like OAuth 2.0 and OpenID Connect is a strong plus.
7. You balance long-term thinking with pragmatic delivery, and thrive in high-autonomy teams.
