Role Description We're building a Cloud Center of Excellence that owns the cloud foundation for the entire engineering organization. You'll design the architecture, automation, and governance that other teams build on - not just deploy workloads, but define how workloads get deployed. If you think about infrastructure as a product and want real ownership over cloud strategy, this is that role. What You'll do: - Design and implement a cloud-native platform architecture on GCP - Build scalable guardrails for multi-team, multi-environment setups with compliance requirements - Create reusable infrastructure that enables self-service provisioning - Define cloud governance: IAM strategies, organizational policies, policy-as-code - Write design documents and represent technical divisions in cross-team and leadership forums Qualifications - Strong hands-on experience with GCP - Production Kubernetes experience - networking, security, tenancy, lifecycle management - Terraform at the module-authoring level, not just the consumer level - Solid networking fundamentals: VPC design, CIDR planning, DNS, hybrid connectivity - Experience working in compliance-driven environments (SOC2, PCI-DSS, or similar) - GitOps methodology and tooling - Observability stack experience (metrics, structured logging, tracing) - Clear technical communication - you can write a design doc and defend it Requirements - You think about infrastructure as a product with users, SLOs, and developer experience - You've designed cloud foundations for organizations, not just individual projects - You build patterns that scale and enable others, rather than solving things one-off - You know how to get buy-in across teams and navigate the human side of platform work - You raise the technical bar for the people around you Benefits - Remote role across Poland - Access to e-learning platforms - eTutor, GoodHabitz, Data Camp, and more - A wide range of benefits, including the MultiSport+ card, private healthcare, and group insurance, available on the Worksmile platform - External and internal growth opportunities - conferences, trainings, workshops - Chances to broaden your skill set and acquire new competencies through daily work, challenging projects, and training activities - B2B type of contract
