Senior Site Reliability Engineer II

Juniper Square is an operations partner providing technology, data, and fund administration services for private markets. The Senior Site Reliability Engineer II will own reliability and observability, manage Kubernetes and AWS infrastructure, build CI/CD pipelines, and drive Infrastructure as Code standards across engineering teams. The role also includes cross-team collaboration, on-call participation, incident response, and adoption of AI tools.

Responsibilities:

• Own reliability and observability across the organization — SLAs/SLOs, instrumentation, and on-call health
• Design, deploy, and maintain Kubernetes infrastructure (Helm, EKS/ECS) and core AWS services (RDS/Aurora Postgres, networking, scaling)
• Build and maintain CI/CD pipelines in GitHub Actions and Argo/Helm
• Drive adoption of Infrastructure as Code standards (Terraform, and increasingly Crossplane) across multiple teams
• Partner with 16+ engineering teams to roll out new standards, tools, and processes — adapting the rollout to how each team actually works
• Participate in on-call rotation and lead incident response/root-cause analysis for issues that cross team boundaries
• Use AI tools daily to work faster and more effectively, and help less AI-fluent teammates pick up the same habits
• Represent SRE's perspective in planning conversations with engineering leadership

Requirements:

• • 8-10 years of experience as a Senior SRE, DevOps, or Infrastructure Engineer
• • Background at smaller-to-mid-size, high-growth SaaS companies (Series A/B through C/D) — you know how to move fast and own ambiguity, not navigate a large, slow-moving org
• • Deep hands-on experience with Kubernetes (EKS or ECS), GitHub Actions, Terraform, CI/CD pipelines, and Helm/Argo
• • Real database experience with Postgres and DocumentDB (Mongo) across RDS/Aurora
• • A track record of working cross-functionally — managing timelines, setting expectations, and collaborating with other teams' engineers, not just your own
• • Already using AI as part of your actual workflow (coding, debugging, design)
• • Crossplane
• • Datadog
