Our cutting-edge infrastructure, hosted on Google Cloud, ensures a seamless gaming experience for our users. Join our team and be part of shaping the future of online gaming! :female-technologist::male-technologist: Are you a seasoned DevOps Engineer looking to take full ownership of a modern cloud platform? Flexsy, a leading Gaming company, is expanding its team and searching for a seasoned DevOps Engineer who doesn't just maintain infrastructure — they continuously evolve it. Key Responsibilities :hammer_and_wrench: As a Remote DevOps Engineer at Flexsy, you will own the reliability, scalability, and cost-efficiency of our cloud platform. Your responsibilities will include: Designing, implementing, and owning end-to-end CI/CD pipelines with a focus on speed, reliability, and zero-downtime deployments. Architecting and fine-tuning highly available, fault-tolerant systems on Google Cloud — including load balancing, auto-scaling groups, multi-region failover, and disaster recovery strategies. Proactively managing cloud costs through resource right-sizing, committed use discounts, autoscaling policies, and infrastructure spend analysis — with measurable impact on monthly GCP bills. Evaluating, onboarding, and deeply configuring new GCP-native and third-party services (e.g., Cloud Spanner, Memorystore, Pub/Sub, Cloud Armor, Vertex AI tooling) to meet evolving product needs. Owning Kubernetes cluster operations: tuning resource requests/limits, configuring HPA/VPA, managing node pools, and optimizing workload scheduling for both performance and cost. Building and enforcing Infrastructure as Code (IaC) standards using Terraform — no manual console changes. Defining and maintaining SLOs/SLIs, setting up alerting strategies, and driving incident response and post-mortems. Collaborating closely with development teams to shape architecture decisions, review infrastructure requirements, and advise on cloud-native design patterns. Leading container strategy: designing production-grade Docker configurations, multi-stage builds, and hardened base images for both local development and production environments. Partnering with QA teams to build robust test automation infrastructure and staging environments that mirror production fidelity. Qualifications :books: 5+ years of hands-on experience in a DevOps or Site Reliability Engineering role, ideally in a high-traffic or real-time product environment. Deep expertise in Google Cloud Platform — not just familiarity, but proven experience designing and tuning production workloads across GCP services. Strong command of Kubernetes in production: cluster tuning, resource optimization, network policies, RBAC, and persistent storage configuration. Demonstrated ability to reduce infrastructure costs — bring examples of cost optimization wins you've personally driven. Solid experience with Infrastructure as Code (Terraform preferred) and GitOps workflows. Proficiency in scripting and automation (Python and/or Bash) for operational tasks, tooling, and custom integrations. Hands-on experience with observability stacks (e.g., Prometheus, Grafana, OpenTelemetry, Cloud Operations Suite) — building dashboards, defining alerts, and acting on data. Experience designing for high availability: understanding of replication, failover, circuit breakers, and graceful degradation patterns. Familiarity with security best practices: secrets management (Vault, GCP Secret Manager), network segmentation, IAM least-privilege, and vulnerability scanning in pipelines. Experience with Bitbucket Pipelines or equivalent CI tooling is a strong plus. Ability to work autonomously, make architectural decisions independently, and communicate trade-offs clearly to both technical and non-technical stakeholders. Benefits: Competitive salary As a growing startup, meaningful opportunities for career growth and technical leadership. Direct influence over infrastructure decisions — no red tape. Health and wellness benefits. Collaborative and inclusive remote-first work environment. Our Unique Culture :star: We are a remote team, but we like to meet at our Athens offices once in a while to catch up in person! We love working with people who take ownership and bring genuine enthusiasm to what they do. We hate micromanagement, traditional hierarchy, and KPIs. :rocket: Ready to own the platform?
