Site Reliability Engineer

We are seeking a Site Reliability Engineer (SRE) with 5–8 years of experience to help build and maintain highly available, scalable, and resilient systems. This role will focus on improving reliability through automation, observability, incident response, and engineering excellence. You will work closely with engineering, product, and operations teams to drive best practices in performance, reliability, and continuous improvement.

Ideal candidates have strong foundations in infrastructure automation, systems engineering, and software development—along with a passion for building reliable systems at scale.

Key Responsibilities:

Reliability Engineering & Automation

• Design and implement Infrastructure as Code (IaC) using Terraform, Pulumi, CloudFormation, or Ansible to provision and manage scalable cloud infrastructure.
• Build self-healing and auto-scaling infrastructure using Kubernetes, Docker, and managed services across AWS, Azure, or GCP.
• Automate operational tasks including failovers, backups, and capacity adjustments.

SLI/SLO Monitoring & Observability

• Define and track Service Level Indicators (SLIs) and Objectives (SLOs) to measure and maintain service reliability.
• Build and manage observability stacks using Prometheus, Grafana, Datadog, CloudWatch, AppD, or equivalent.
• Improve alert quality and reduce noise through intelligent alerting and tuning.

Incident Response & Operational Excellence

• Lead production incident response, perform root cause analysis (RCA), and write blameless postmortems to drive continuous improvement.
• Establish and refine runbooks, playbooks, and on-call processes to improve Mean Time to Recovery (MTTR).
• Participate in on-call rotations to support critical production systems.

CI/CD Reliability & Release Engineering

• Develop and optimize CI/CD pipelines (Jenkins, GitHub Actions, ArgoCD, TeamCity) with built-in checks for reliability, performance, and security.
• Implement progressive delivery patterns like canary deployments and blue/green rollouts.
• Collaborate with developers to ensure release processes are safe, repeatable, and observable.

Security, Compliance & Risk Management

• Enforce cloud security best practices for IAM, network segmentation, and secret management.
• Integrate DevSecOps practices and tooling (e.g., Snyk, SonarQube, OWASP ZAP) into pipelines for early vulnerability detection.
• Ensure systems adhere to regulatory and compliance standards (SOC2, ISO 27001, GDPR, HIPAA, etc.).

Collaboration & Mentorship

• Work cross-functionally with engineering, QA, and platform teams to embed reliability into the SDLC.
• Provide guidance and mentorship to junior SREs and engineers on reliability practices.
• Champion a culture of operational excellence, documentation, and knowledge sharing.

Skills & Qualifications:

Technical Expertise

• Cloud Platforms: Strong hands-on experience with AWS, GCP, or Azure across compute, networking, storage, and identity.
• Kubernetes: Advanced experience managing production-grade clusters (EKS, GKE, AKS), Helm, and containerized workloads.
• CI/CD Tools: Jenkins, GitHub Actions, ArgoCD, TeamCity, Spinnaker (preferred).
• IaC: Terraform, CloudFormation, Pulumi, Ansible (strong experience required).
• Programming & Scripting: Proficiency in Python, Go, or Java. Strong scripting skills with Bash or PowerShell.
• Version Control: Expert-level Git usage and branching strategies (GitOps experience is a plus).
• Monitoring & Logging: Familiarity with Prometheus, Grafana, ELK, Datadog, New Relic, or AppD.

Security & Compliance

• Strong understanding of cloud security principles and IAM policies.
• Experience with automated security testing and static code analysis tools.

Soft Skills

• Analytical thinker with strong troubleshooting and problem-solving skills.
• Clear communication and ability to drive cross-team collaboration.
• Strong ownership mindset and bias for action in high-pressure situations.
• Ability to manage multiple priorities and lead technical initiatives.

Preferred Qualifications:

• Certifications: AWS Solutions Architect, GCP Professional Cloud DevOps Engineer, or Azure DevOps Expert.
• Experience with GitOps tooling such as GitHub, Jenkins, ArgoCD, TeamCity, jFrog, etc.
• Exposure to serverless architecture (Lambda, GCF, Azure Functions).
• Experience with chaos engineering and resiliency testing frameworks

Education & Experience:

• Bachelor's degree in Computer Science, Information Technology, or a related field.
• 5+ years of experience in SRE, DevOps, or cloud infrastructure roles with a focus on system reliability.
