We are looking for a Senior DevOps Engineer to join our Engineering team and work directly on our product critical path: deployment, orchestration, observability, and secure communication — using the latest technologies in the industry.

Requirements

  • 6+ years of hands-on DevOps / SRE experience operating large-scale SaaS or regulated environments
  • Strong proficiency in one or more programming/scripting languages (e.g., Python, Go, Bash, PowerShell, C/C++, Java, JavaScript)
  • Solid experience with cloud infrastructure (Microsoft Azure preferred)
  • Hands-on experience with Kubernetes in production (AKS preferred)
  • Proven experience building and maintaining CI/CD pipelines (Azure DevOps, GitHub Actions)
  • Experience with Infrastructure-as-Code tools to manage cloud resources and deployments (e.g., Terraform/Terragrunt, Helm charts, Kustomize)
  • Experience with GitOps practices and tools (Argo CD preferred)
  • Familiarity with monitoring, logging, and alerting stacks — Prometheus, Grafana, Azure Monitor, OpenTelemetry — including SLO/SLA definition and audit/security logging
  • Experience with cloud and container security best practices
  • Demonstrated ability to lead technical projects — building, managing, and troubleshooting large-scale distributed systems or cloud infrastructure with a Kubernetes focus
  • Ability to debug and optimize across code, networking, storage, and systems layers while communicating clearly with technical and non-technical stakeholders
  • Experience with incident management processes and participating in an on-call rotation
  • Strong cross-functional collaboration and stakeholder management skills
  • Excellent problem-solving and communication skills
  • First-principles thinking — you break problems down to root causes before jumping to solutions
  • Continuous learning mindset — you stay current, experiment with new tools, and share knowledge with the team
  • Security-first and developer experience mindset — you balance robust security with friction-free developer workflows, while keeping cost efficiency in view
  • You dare to ask questions and challenge decisions with solid data — respectfully and constructively
