Martin Polednik
VP Of Engineering at JustWatch
Berlin, Germany
Summary
👤
SeniorMartin Polednik is a VP of Engineering based in Berlin with 11 years of experience building and scaling infrastructure for high-traffic products. He combines deep hands-on expertise in virtualization, containers and performance (notably contributions to oVirt and KubeVirt) with a strategic leadership style that stays close to engineering decisions and serves as a practical tie-breaker on technical trade-offs. Martin has led platform and infrastructure teams through cloud migrations, M&A integrations and cost optimizations, while cultivating an engineering culture that treats developers as innovators rather than ticket processors. His background spans low-level virtualization work (vfio, hugepages, device passthrough) to running production Kubernetes fleets and CDNs supporting millions of users. An avid Linux and IoT tinkerer and AI/ML enthusiast, he still enjoys digging into code and architecture even while operating at the executive level.
