You will drive reliability through SLOs, automation and scalable pipelines, collaborating with software engineers to embed observability and resilience into service design.

Qualifications

• Bachelor’s degree in Computer Science or equivalent practical experience.
• 5+ years of experience as a Site Reliability Engineer or Platform Engineer with strong knowledge of software development best practices.
• Strong hands‑on experience with public cloud services (AWS, GCP, Azure) and supporting SaaS product.
• Strong programming or scripting skills (e.g., Python, Go, Bash...), and experience with infrastructure-as-code (e.g. Terraform).
• Proficiency with Kubernetes, container-based deployment (e.g., Docker) and related ecosystems (e.g., Helm).
• Experience supporting multi‑tenant microservices architectures.
• Experience with CI/CD pipelines & tools (e.g., Jenkins, GitHub Actions, GitLab CI, FluxCD, Crossplane).
• Experience with managing monitoring solutions (e.g. Datadog).
• Comfortable participating in a rotating on‑call schedule, managing critical incidents, and leading post‑incident reviews.
• Strong system‑level troubleshooting skills and a proactive mindset toward incident prevention.
• Deep understanding of Linux systems, networking, and common troubleshooting practices.
• Knowledge of zero‑downtime deployment strategies (blue/green, canary).
• Exposure to SOC 2, ISO 27001, HIPAA; FedRAMP is a plus.
• Experience with chaos engineering or resilience testing.

Responsibilities

• Implement and manage cloud-native systems (AWS) using best-in-class tools and automation.
• Operate and enhance Kubernetes clusters, deployment pipelines, and service meshes to support rapid delivery cycles.
• Design, build, and maintain infrastructure powering a multi-tenant SaaS platform with reliability, security, and scalability.
• Define and maintain SLOs, SLAs, and error budgets, and address availability and performance issues.
• Develop infrastructure-as-code (Terraform or similar) for repeatable provisioning.
• Build internal platform tools and automation to support provisioning, monitoring, and operational efficiency.
• Monitor infrastructure and applications ensuring high-quality user experiences.
• Participate in a shared on-call rotation, incidents, outages, resolution and communication.
• Act as Incident Commander during on-call duty and coordinate cross-team responses to maintain an SLA.
• Drive and refine incident response processes, reducing MTTD and MTTR.
• Diagnose and resolve complex issues independently, minimizing external escalation.
• Collaborate with software engineers to embed observability, fault tolerance, and reliability into service design.
• Automate runbooks, health checks, and alerting to support reliable operations with minimal manual intervention.
• Support automated testing, canary deployments, and rollback strategies for safe, fast releases.
