Senior Site Reliability Engineer

Juniper Square is a company focused on unlocking the potential of private markets through technology and services. They are seeking a Senior Site Reliability Engineer II to enhance their infrastructure and reliability practices, working closely with multiple engineering teams to implement standards and automation.

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
