DevOps Senior Engineer

The hiring client is confidential. The Senior DevOps Engineer will lead migrations from Jenkins and GitHub Actions to standardized Harness CI/CD structures, establish reusable platform automation patterns, and optimize delivery performance. The role also provides technical direction and mentorship while supporting application delivery across AWS, Kubernetes, and on-premise environments.

Responsibilities:

• Lead the technical migration of Jenkins and GitHub Actions workflows into Harness
• Assess existing pipelines, shared libraries, actions, integrations, credentials, runners, and deployment processes
• Design and implement reusable Harness steps, step groups, stages, pipelines, and templates
• Establish standards for Harness pipeline architecture, template reuse, inputs, variables, secrets, approvals, and deployment patterns
• Develop migration patterns that simplify and standardize existing CI/CD implementations rather than simply reproducing legacy pipelines
• Design CI/CD patterns supporting Java, Go, Node.js, and Python applications
• Establish and support GitOps-based application and infrastructure delivery
• Design and maintain reusable Helm charts and Kubernetes deployment patterns
• Develop and integrate Infrastructure as Code using OpenTofu/Terraform
• Develop and integrate configuration automation using Ansible
• Support delivery across AWS, Kubernetes, virtual machines, and traditional on-premise datacenter environments
• Troubleshoot complex pipeline, build, infrastructure, networking, and deployment issues
• Optimize pipeline performance, reliability, caching, parallelization, resource utilization, and failure diagnostics
• Design self-service and reusable delivery capabilities that reduce application-team onboarding effort
• Establish appropriate CI/CD governance, security, approval, and policy controls
• Conduct pipeline, template, IaC, and automation reviews
• Mentor DevOps engineers and provide technical direction for migration activities
• Partner with application, infrastructure, cloud, architecture, and security teams to resolve migration dependencies and technical blockers

Requirements:

• 6+ years of hands-on DevOps, CI/CD, platform engineering, SRE, build/release engineering, or infrastructure automation experience
• Strong hands-on experience designing and operating enterprise CI/CD platforms
• Practical Harness.io CI/CD experience, including pipeline and template development
• Strong experience with Jenkins pipelines and migration/modernization activities
• Experience with GitHub Actions and Git-native CI/CD workflows
• Strong understanding of Git, branching/release strategies, and GitOps principles
• Advanced YAML and configuration-as-code skills
• Strong experience with Terraform and/or OpenTofu, including reusable module development
• Strong experience with Ansible, including roles and playbooks
• Strong hands-on Kubernetes and Helm experience
• Experience designing and maintaining reusable Helm charts
• Strong working knowledge of AWS infrastructure and application delivery
• Experience supporting hybrid cloud and on-premise datacenter environments
• Strong Linux, scripting, and command-line troubleshooting skills
• Automation experience using Python, Bash, Go, or similar languages
• Working knowledge of build, packaging, and dependency-management patterns for Java, Go, Node.js, and Python
• Experience with containers, artifact repositories, and container registries
• Demonstrated ability to independently diagnose complex CI/CD and infrastructure problems
• Ability to quickly assess existing delivery implementations and make sound architectural decisions with minimal ramp-up
• Able to become productive immediately in complex CI/CD and infrastructure environments
• Strong automation, architecture, and troubleshooting skills
• Capable of independently driving migrations from discovery through production cutover
• Able to recognize recurring patterns and convert them into reusable platform capabilities
• Strong technical leadership and mentoring skills
• Pragmatic approach to standardizing legacy and cloud-native environments
• Developer-focused approach to platform engineering and automation
• Strong cross-functional communication and technical documentation skills
• Comfortable making technical decisions and resolving blockers with limited oversight
• Deep experience with Harness.io CI and CD
• Harness pipeline and template architecture at organizational scale
• Harness Git Experience and configuration-as-code practices
• Harness delegate architecture and troubleshooting
• Experience performing Jenkins-to-Harness migrations
• Experience migrating GitHub Actions workflows into Harness
• Experience building standardized or ""golden path"" CI/CD capabilities
• GitOps architecture and implementation
• AWS and Kubernetes platform engineering
• CI/CD performance optimization and delivery telemetry
• REST API and integration automation
• Secrets-management and software supply-chain security experience
• DORA metrics — Deployment Frequency, Lead Time for Changes, Change Failure Rate*** and Mean Time to Restore/Recovery
• OPA / Open Policy Agent and Policy as Code
• Harness or enterprise CI/CD governance and automated guardrails
• Software supply-chain security, artifact provenance, and SBOM concepts
• SAST, SCA, container scanning, and automated security controls
• Progressive delivery, canary, and blue/green deployment strategies
