Senior DevOps Engineer

Ciklum is looking for a Senior DevOps Engineer to join our team in Brazil.

We are a custom product engineering company that supports both multinational organizations and scaling startups to solve their most complex business challenges. With a global team of over 4,000 highly skilled developers, consultants, analysts and product owners, we engineer technology that redefines industries and shapes the way people live.

About the role:

As a Senior DevOps Engineer, you'll become a part of a cross-functional development team engineering experience of tomorrow. We are looking for a talented Senior DevOps Engineer to support our engineering work, with a strong focus on the underlying infrastructure that we need to get from source code to production, plus keep it happy once it's there. We need someone who understands software development and enjoys working with developers on all the things necessary to improving, deploying, monitoring, and operating production services.

Responsibilities:

Build complex, highly available, and cost-optimized cloud infrastructure solutions on Azure and in Kubernetes (AKS)

Design, build, and maintain production-grade AKS clusters, including private cluster networking, node pool sizing and autoscaling, workload identity, ingress, certificate management, and cluster upgrade lifecycle

Own infrastructure as code end to end in Terraform: author and refactor reusable modules, manage per-environment workspaces and state, and drive changes through pull request, plan review, and apply

Design and implement advanced CI/CD pipelines ensuring quality, security, and efficiency, including container image build/publish and progressive promotion from lower environments to production

Establish comprehensive monitoring and observability strategies across cluster, application, and Azure platform services

Proactively identify and mitigate risks, leading troubleshooting efforts for complex issues across compute, networking, identity, and data layers

Implement high-level security practices, integrating vulnerability scanning and threat modeling, and manage secrets through a centralized secrets store with identity-based (rather than credential-based) access

Maintain and exercise multi-region high availability and disaster recovery, including failover and failback procedures for Kubernetes workloads and managed databases

Work with application engineering to cultivate operational standards

Requirements:

We know that sometimes, you can't tick every box. We would still love to hear from you if you think you're a good fit!

Bachelor's degree in Computer Science, Software Engineering, or a related field, or equivalent work experience

5+ years of experience in a DevOps engineering role with significant Azure experience

Proven track record of designing and implementing large-scale Azure solutions

Hands-on experience running AKS in production, not just in development or proof-of-concept environments — including private clusters, cluster upgrades, autoscaling, and incident response on live workloads

Advanced, production-level Terraform experience: module design, state and workspace management, and multi-environment/multi-subscription deployments

Demonstrated ability to solve complex technical problems and architect robust solutions

Excellent communication and collaboration skills

Azure certifications (e.g., Azure Solutions Architect Expert, Azure DevOps Engineer Expert, Certified Kubernetes Administrator)

Desirable:

Cloud: Deep knowledge of Azure services, architectures, and design patterns, including Entra ID, RBAC, managed identities and workload identity federation, Key Vault, and subscription/landing zone structure

Infrastructure as Code (IaC): Advanced skills in Terraform, or other IaC tools

CI/CD: Strong experience with pipeline-as-code (Azure Pipelines, GitHub Actions, or equivalent), service connections and federated pipeline authentication, and GitOps-style continuous delivery to Kubernetes (Argo CD, Fl
