About the role
We are seeking a Senior DevOps Engineer to own and evolve the infrastructure, deployment pipelines, and operational reliability of a high-traffic SaaS platform running on AWS. You will manage a Kubernetes-based microservices architecture serving multiple web applications, APIs, and asynchronous workloads across production, staging, and development environments.
Technology Environment
- Cloud: AWS (EKS, Aurora PostgreSQL, S3, ALB, WAF, IAM, VPC)|
- Orchestration | Kubernetes on EKS
- IaC: Terraform (modular, multi-environment)
- Containers: Docker (20+ custom images)
- CI/CD: GitHub Actions
- Monitoring: Prometheus, Grafana, Alertmanager
- Logging: Elasticsearch, Logstash, Kibana, Filebeat
- Data Stores: MongoDB (replica set), Aurora PostgreSQL, Redis, RabbitMQ
- Application: PHP / Symfony, Node.js, React
Required Technical Skills
- Cloud Infrastructure
- Deep experience with AWS, including compute, networking, storage, IAM, and managed database services. You should be comfortable designing and maintaining VPCs, load balancers, and multi-environment cloud architectures.
- Container Orchestration
- Strong hands-on experience with Kubernetes in production: deploying, scaling, and troubleshooting workloads including Deployments, StatefulSets, DaemonSets, CronJobs, Ingress, RBAC, and storage. Experience with autoscaling strategies (HPA, event-driven, or scheduled) is expected.
- Infrastructure as Code
- Proficiency with Terraform or similar IaC tools for provisioning and managing cloud infrastructure. Experience with modular design, remote state management, and multi-environment workflows.
- Containerization
- Solid experience with Docker, including writing and optimizing Dockerfiles, managing image registries, and supporting containerized local development environments.
- CI/CD Pipelines
- Experience building and maintaining automated build, test, and deployment pipelines using GitHub Actions or similar platforms. Understanding of container image promotion workflows and environment-based deployment strategies.
- Monitoring & Observability
- Experience with metrics-based monitoring and alerting using tools such as Prometheus, Grafana, and Alertmanager or equivalent. Comfortable building dashboards, writing alert rules, and integrating with notification channels.
- Logging & Log Aggregation
- Familiarity with centralized logging pipelines using tools such as the ELK stack (Elasticsearch, Logstash, Kibana) or similar. Understanding of log collection, transformation, indexing, and retention strategies.
- Database & Data Store Operations
- Working knowledge of operating and supporting MongoDB, PostgreSQL, Redis, and RabbitMQ or similar technologies in production. This includes backup/restore procedures, replica management, and basic performance tuning.
- Networking & Security
- Understanding of cloud networking fundamentals (VPCs, subnets, security groups, DNS), TLS/SSL certificate management, WAF configuration, and securing internal tools. Familiarity with authentication proxies and access control patterns.
- Scripting & Automation
- Proficiency in Bash and/or Python for operational automation. Ability to read and understand application configurations (PHP, Node.js) enough to support deployment and troubleshooting workflows.
Preferred Technical Skills
- Experience with event-driven autoscaling tools such as KEDA
- Familiarity with GitOps workflows and an interest in evolving deployment practices
- Exposure to workflow automation platforms (n8n or similar)
- Experience with cost optimization strategies (spot instances, right-sizing, lifecycle policies)
- Familiarity with error tracking platforms such as Sentry
