Job Teaser

As a Senior Software Engineer, you will be a core contributor to our Identity and User Management domain. You'll be responsible for the secure design, hands-on development, and operation of the backend services that integrate with our Keycloak instance. This role is ideal for a seasoned engineer with 5+ years of experience who is proficient in the JVM ecosystem and passionate about taking ownership of mission-critical production systems and driving technical excellence within an international agile team.

What you can expect

Architect and Develop Core Services: Design, develop, and operate critical backend services within our User Management domain, ensuring seamless and secure integration with our Keycloak instance.
Leverage the JVM Stack: Work hands-on with our primary technology stack, which is mostly JVM-based (Kotlin, Micronaut), alongside auxiliary components written in Python and Go.
Drive Engineering Excellence: Develop software following modern practices: API first, code reviews, automated tests, and utilizing MR environments for exploratory testing before a merge.
Own the Topics: Take charge of technical topics important to you, driving significant decisions, and seeking alignment across teams within our backend guild.
Deployment and Operations: Deploy (Kubernetes, Helm) and monitor (Grafana, Sentry, Mixpanel) your services within the team, with the support of a separate team of SREs for on-call duty.

What you bring to the table

We're seeking a skilled, experienced engineer ready to step up and own complex integration challenges.

Must Haves:

Proven Experience: 5+ years of software engineering experience, ideally in backend or full-stack development.
Core Language Proficiency: Very good knowledge of Kotlin/Java and relevant Frameworks (such as Micronaut, Spring, etc.).
Production Operations: Demonstrable hands-on experience in deploying and running applications on production systems (e.g., cloud, containerized environments).
Ownership and Collaboration: Strong sense of responsibility and ownership for your topics, coupled with a collaborative mindset and excellent communication skills.

Familiarity with PostgreSQL.
Experience with messaging systems (RabbitMQ, Apache Kafka).
Prior exposure to Keycloak or similar Identity and Access Management (IAM) solutions.

What we offer you

Work mode: We’re remote-first, giving you flexibility to work from home. At the same time, we deeply value the power of in-person collaboration.

The exact balance will be discussed during your interview.
Work-Life-Balance: We don't want you to grow roots to your desk chair. That's why we cover the costs of your E-Gym-Wellpass membership and offer job bike leasing.
Celebrating success: Expect highly motivated and committed people in a relaxed working atmosphere.
Be part of something bigger: You actively shape Flip in your role. Along the way, you are an enabler of the rapid growth process of a young tech company and grow towards your goals, fun is guaranteed.
