What We Are Looking For

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. You will focus on both platform-level DevOps requirements and embedding DevOps best practices into our products.

What You Will Be Doing

• Design, implement, and continuously improve CI/CD pipelines and release processes across product teams

• Build and maintain cloud infrastructure using Infrastructure-as-Code (Terraform/Terragrunt, Helm charts, Kustomize, Bicep/ARM)

• Operate and scale Kubernetes clusters (AKS) and supporting services (networking, storage, service mesh)

• Implement and maintain GitOps workflows using Argo CD for declarative, auditable deployments

• Deploy and manage observability stacks - metrics, logging, alerting, tracing (Prometheus, Grafana, Azure Monitor, OpenTelemetry) with well-defined SLOs/SLAs

• Manage onprem and cloud resources, optimize costs, and ensure infrastructure health and security across environments

• Participate in incident management whenever required - on-call rotation, triage, resolution, and blameless post-incident reviews

• Automate routine operational tasks, debug complex infrastructure issues, and optimize system performance

• Collaborate cross-functionally with product engineering, QA, security, and support teams to drive reliable delivery

• Document procedures, runbooks, and architectural decisions with clarity and consistency

What You Will Bring

Required

• 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

• Collaborative, flexible, and friendly — you thrive in a diverse, globally distributed team and bring positive energy to every interaction

Bonus Points

• Relevant certifications in Azure, Kubernetes (CKA/CKAD), Security, or Linux

• Good knowledge of Linux internals (filesystems, inodes, system calls) and networking (TCP/IP, routing, network topologies, SDN)

• Experience with Microsoft Windows & Microsoft environments, MS Build, and Windows-based troubleshooting

• Knowledge of building AI agents or using LLMs to automate routine DevOps tasks

• Exposure to MLOps workflows and tooling

• Experience with service mesh technologies (e.g., Istio)

• Experience with event-driven architectures (e.g., Kafka) and microservices patterns

• Exposure with SBOM generation, software supply chain security, or compliance frameworks (ISO 27001, SOC 2, FedRAMP/NIST)

• Master's degree or PhD in Computer Science, Engineering, or a related field (or equivalent practical experience)
