Platform Engineer

At Avaron, you get the security of permanent employment combined with the variety of working at different customers. We place specialists across everything from tech, IT and industry to project management and business support – and whatever the assignment, you have a consultant manager who is there for you and your development.

You will help shape a shared integration platform used by multiple development teams in a large enterprise environment. The focus is on building and operating reliable messaging and integration capabilities where stability, automation, self-service, and end-to-end ownership are central.

This role centers on Apache Kafka and HiveMQ in Kubernetes, with responsibility for platform reliability, security, scalability, and continuous improvement. You will work closely with architecture, security, and development teams, and the role is especially interesting if you enjoy combining deep platform engineering with real influence on how teams consume integration services.

• You implement security and governance controls through Schema Registries, Kafka ACLs, SASL, OAuth/OIDC validation paths, mTLS, SSL verification, and RBAC.

• You perform root cause analysis for outages, build automated guardrails to prevent recurrence, and provide Tier 3 support for complex integration issues.

• You handle incident, problem, and change management at platform level together with security, architecture, and development teams.
