Berlin, Germany
Summary
🤩
Rockstar🎓
Top SchoolMarcin Bienek is an SRE Engineering Manager based in Berlin with 11 years of hands-on experience and 17 years in IT, leading teams that operate high-throughput platforms handling up to 80k requests/s and sustained 25% YoY growth. He combines strategic leadership—setting roadmaps, hiring, and budget oversight for a $6M infrastructure spend—with deep technical execution, from zero-downtime datacenter migrations and MySQL-to-Aurora moves to designing Kubernetes operators and autoscaling Elasticsearch. Known for driving cost savings (over $1M/year) and automating SLO, dashboard, and alert creation at scale, he prioritizes reducing toil and increasing engineering bandwidth. Comfortable in both on-prem and cloud environments, he has built and run massive monitoring, Kafka, Cassandra, and time-series systems and has led large multi-region platform builds. Pragmatic and slightly irreverent about trends, he thrives on turning chaotic operational challenges into repeatable, scalable systems.
