⁠⁠⁠We are looking for a Senior DevOps Engineer with strong hands-on experience in Kubernetes, AWS, CI/CD, automation, monitoring, and production system reliability.

You will join a collaborative DevOps team of 9+ engineers across multiple countries, supporting and improving global distributed production systems. The role provides exposure to complex infrastructure challenges, including high availability, scalability, security, cost optimization, disaster recovery, and cross-region operations.

You will also have the opportunity to work on AWS-recognized cloud and infrastructure projects, applying modern cloud-native practices across Kubernetes, infrastructure-as-code, observability, and automation.

We are looking for someone who is smart, hands-on, proactive, and structured in problem-solving — someone who can not only operate systems, but also improve them for long-term stability, scalability, and engineering efficiency.

Key Responsibilities

Infrastructure & Kubernetes

• Design, build, operate, and improve Kubernetes-based infrastructure.
• Manage Kubernetes clusters, workloads, networking, storage, ingress, service discovery, and autoscaling.
• Improve deployment reliability, cluster stability, resource utilization, and operational visibility.
• Support containerized application deployment across different environments.
• Troubleshoot Kubernetes issues related to pods, nodes, networking, DNS, storage, and performance.

Cloud & System Operations

• Manage cloud infrastructure on platforms such as AWS, Azure, GCP, or similar.
• Maintain and improve Linux-based production environments.
• Support high-availability, low-latency, and business-critical systems.
• Perform capacity planning, cost optimization, disaster recovery planning, and infrastructure scaling.
• Ensure infrastructure is secure, observable, resilient, and easy to operate.

CI/CD & Automation

• Build and maintain CI/CD pipelines for application and infrastructure deployment.
• Automate repetitive operational tasks using scripts, tools, and infrastructure-as-code.
• Improve deployment speed, rollback capability, release safety, and developer productivity.
• Work with tools such as GitLab CI, GitHub Actions, Jenkins, Argo CD, Helm, Terraform, Ansible, or similar.

Monitoring, Reliability & Incident Response

• Build and improve monitoring, logging, alerting, and observability platforms.
• Work with tools such as Prometheus, Grafana, Loki, ELK, CloudWatch, Datadog, or similar.
• Participate in incident response, root cause analysis, and post-incident improvement.
• Identify system bottlenecks and propose long-term solutions instead of short-term fixes.
• Improve system reliability, availability, and operational readiness.

Collaboration & Engineering Support

• Work closely with developers, QA, security, system administrators, and business teams.
• Help development teams improve application deployment, configuration, performance, and reliability.
• Provide technical guidance on infrastructure design and operational best practices.
• Document architecture, operational procedures, runbooks, and troubleshooting guides.

Requirements

Must Have

• Strong hands-on experience with Kubernetes in production environments.
• Solid understanding of containers, Docker, Helm, ingress controllers, service mesh, and Kubernetes networking.
• Strong Linux system administration skills.
• Experience with CI/CD pipeline design and automation.
• Experience with cloud infrastructure such as AWS, Azure, GCP, or private cloud.
• Experience with Infrastructure as Code, such as Terraform, CloudFormation, Ansible, or similar.
• Good scripting ability using Bash, Python, Go, or similar.
• Strong troubleshooting skills across application, infrastructure, network, and system layers.
• Good understanding of monitoring, logging, alerting, and incident response.
• Able to work independently and handle production issues under pressure.

Preferred Qualifications

• Experience supporting financial, trading, payment, SaaS, or other high-availability systems.
• Experience with AWS EKS, MSK/Kafka, RDS, Redis, S3, CloudFront, Route 53, WAF, or similar services.
• Experience with GitOps tools such as Argo CD or Flux.
• Experience with service mesh such as Istio, Linkerd, or Consul.
• Experience with security hardening, secrets management, IAM, network security, and compliance.
• Experience with multi-region, hybrid cloud, or disaster recovery architecture.
• Experience optimizing infrastructure cost and resource usage.
• Experience supporting low-latency or high-throughput systems.

What We Are Looking For

We are looking for someone who is:

• Smart and logical: able to break down complex problems clearly.
• Hands-on: not only understands concepts, but can execute and fix real production issues.
• Proactive: able to identify problems before they become incidents.
• Reliable under pressure: calm and structured during production issues.
• Automation-minded: prefers repeatable systems over manual operations.
• Security-conscious: understands the importance of access control, secrets, auditability, and system hardening.
• Business-aware: understands that infrastructure decisions affect system stability, cost, delivery speed, and user experience.
• A strong communicator: able to explain technical issues clearly to both technical and non-technical stakeholders.
