Senior DevOps Engineer

Title: Senior DevOps Engineer Location: Limassol, Cyprus

About the Role

We are looking for a Senior DevOps Engineer for the Core Product team. The role focuses on operating and scaling Kubernetes-based service platforms (both vanilla Kubernetes and AWS EKS), infrastructure automation, writing Helm and GitLab CI pipelines, and automating deployments for complex systems with many dependencies. You will play a key role in ensuring platform reliability and building secure systems for multiple game-related products and regulated markets.

Key Responsibilities

• Maintain, operate, and scale Kubernetes clusters (both vanilla and EKS) across environments (dev/stage/pre-prod/prod).
• Automate the deployment and lifecycle management of complex systems with a large number of inter-dependencies.
• Deploy, manage, and optimize stateful data services and message brokers (Valkey, MongoDB, ClickHouse, NATS) running directly within Kubernetes clusters.
• Write and maintain Helm charts and build robust CI/CD pipelines (GitLab CI) to standardize and automate deployments.
• Manage infrastructure as code with Terraform; design modular and reusable configurations for cloud environments.
• Design and implement infrastructure with a security-first mindset, ensuring the deployment of secure systems, zero-trust policies, and access workflows (Vault, RBAC).
• Operate service mesh and traffic management layers (Istio, gateways, routing, canary) as well as edge security (Cloudflare).
• Work with established observability stacks (Grafana/Prometheus/Coralogix/ELK) to set up alerts, troubleshoot issues, and monitor system health.
• Lead production incident troubleshooting, perform blameless RCA, and drive systemic reliability improvements.
• Collaborate closely with developers and security teams to support releases and compliance requirements.

Requirements (Must Have)

• 6+ years of DevOps/SRE/Platform engineering experience.
• Deep general Kubernetes expertise, with strong production operations and troubleshooting skills across both vanilla K8s and managed clusters.
• Proven experience operating and troubleshooting stateful workloads and databases in Kubernetes (Valkey, MongoDB, ClickHouse, NATS or similar).
• Extensive hands-on experience writing Helm charts and building advanced GitLab CI pipelines.
• Proven experience in automating the deployment of complex, multi-component systems with numerous dependencies.
• Strong understanding of building secure systems, network security fundamentals (TCP/IP, TLS, firewalls), and secrets/access control (Vault).
• Strong experience with IaC (Terraform) for cloud environments and Git-based workflows.
• Solid GitOps experience (ArgoCD or similar).
• Experience with Linux administration and scripting (Bash/Python or Go).
• Strong production troubleshooting, debugging, and incident response skills.

Nice to Have

• Production experience with Istio and multi-cluster service mesh traffic management.
• Experience with AWS cloud services (VPC, IAM, EC2, ALB/NLB).
• Hands-on experience with Cloudflare (CDN/WAF/DNS).
• Experience with regulated or geo-restricted environments and third-party partner integrations.
