We are looking for a Senior Site Reliability Engineer who is passionate about building and maintaining highly available, scalable, and resilient systems. In this role you will serve as a senior engineer on the SRE team, driving reliability improvements across our production infrastructure while mentoring engineers and shaping our incident response culture.

You will partner closely with software engineering, security, and product teams to embed reliability into every stage of the development lifecycle. This is a high-impact position for someone who thrives at the intersection of software engineering and operations.

Key Responsibilities
  • Design, build, and maintain production infrastructure across cloud platforms (AWS, GCP, or Azure) ensuring 99.99%+ availability targets
  • Define and champion SLOs, SLIs, and error budgets; drive data-informed reliability decisions across engineering teams
  • Lead incident response efforts as Incident Commander; conduct blameless post-mortems and drive remediation to completion
  • Develop and maintain infrastructure-as-code (Terraform, or CloudFormation) and CI/CD pipelines for automated, repeatable deployments
  • Build and improve observability platforms using tools such as Prometheus, Grafana, NewRelic,Splunk, or the ELK stack
  • Automate toil reduction through custom tooling, self-healing systems, and proactive capacity planning
  • Architect and operate container orchestration systems (Kubernetes, ECS) at scale with emphasis on cost efficiency and performance
  • Collaborate with security teams to embed security best practices into infrastructure and deployment pipelines
  • Mentor junior and mid-level SREs through code reviews, knowledge-sharing sessions, and pair-programming
  • Contribute to the on-call rotation and continuously improve runbooks, alerting, and escalation procedures

Required Qualifications
  • 7+ years of experience in SRE, DevOps, or platform engineering roles with progressive responsibility
  • Strong proficiency in at least one programming language (Python, Go, Java, or similar) for systems-level automation and tooling
  • Deep hands-on experience with at least one major cloud provider (AWS, GCP, or Azure) including networking, IAM, and managed services
  • Expert-level knowledge of container orchestration (Kubernetes) and microservices architectures
  • Demonstrated experience defining SLOs/SLIs and managing error budgets in production environments
  • Solid understanding of distributed systems concepts: consensus algorithms, CAP theorem, eventual consistency, and fault-tolerant design
  • Proficiency with infrastructure-as-code tools (Terraform, CloudFormation) and configuration management
  • Experience with CI/CD platforms (Jenkins, GitHub Actions) and GitOps workflows
  • Strong Linux systems administration skills and networking fundamentals (TCP/IP, DNS, load balancing, CDN)
  • Proven track record of leading incident response, writing effective post-mortems, and implementing systemic fixes

Preferred Qualifications
  • Familiarity with chaos engineering practices and tools
  • Background in database reliability engineering (Oracle, PostgreSQL, MySQL, Redis, or Cassandra at scale)
  • Hands-on experience with FinOps practices and cloud cost optimization
  • Contributions to open-source SRE or infrastructure projects
  • Relevant certifications (CKA, AWS Solutions Architect Professional, GCP Professional Cloud Architect)

Technical Environment

Our stack includes Kubernetes, Terraform, AWS, NewRelic,Prometheus and Grafana for monitoring, PagerDuty for on-call, GitHub Actions for CI/CD, and a mix of Java, Go and Python microservices. We are a team that values automation over manual intervention and continuously invest in reducing toil.

What We Offer
  • Competitive base salary with annual performance bonuses
  • Comprehensive health, dental, and vision insurance with generous employer contribution
  • Flexible hybrid/remote work model
  • Annual learning and development budget for conferences, certifications, and courses
  • Generous PTO policy, paid parental leave, and wellness programs
  • 401(k) with employer match
  • Collaborative, blameless engineering culture that values continuous improvement
