Circle; United States; Remote; USD 153,000 - 205,000; Full time

Job summary

Circle is hiring a Senior Site Reliability Engineer to design, build, and operate the scalable platform behind digital assets and applications. You will implement infrastructure as code with Terraform, develop services in Go/Python/JS, and partner with product and engineering teams to ensure reliability.

We value ownership, strong Kubernetes expertise, and a security-minded approach as we support regulated, high‑availability environments across hybrid/public clouds.

Qualifications

• 5+ years of experience in Site Reliability Engineering, DevOps, Infrastructure Engineering, or a closely related software engineering role supporting production systems.
• Deep, hands‑on Kubernetes expertise: designing, operating, securing, and troubleshooting production clusters and containerized workloads at scale.
• Strong Terraform experience, including authoring reusable modules, managing state and environments, and delivering infrastructure changes through reviewable, automated workflows.

Responsibilities

• Design, build, and operate the secure, scalable platform infrastructure behind critical digital assets, AI, and application workloads.
• Develop infrastructure as code with Terraform, creating reusable modules, safe delivery workflows, and well‑governed infrastructure changes.
• Develop backend services, internal tools, and operational automation in Go, Python, or JavaScript/TypeScript to eliminate manual work and improve the developer experience.
• Partner with engineering and product teams to understand workload requirements and design pragmatic solutions for reliability, performance, capacity, security, and cost.
• Improve the production lifecycle through reliable CI/CD, deployment automation, progressive delivery, and clear operational ownership.
• Define and evolve observability practices across metrics, logs, traces, alerting, and dashboards so teams can detect issues early and troubleshoot effectively.
• Own production reliability by participating in on‑call, leading incident response, performing root‑cause analysis, and driving blameless postmortems and durable corrective actions.
• Establish and maintain reliability targets through meaningful SLIs, SLOs, error budgets, capacity planning, disaster‑recovery testing, and resilience improvements.
• Embed security and compliance into platform operations, partnering with Security to protect infrastructure, workloads, and data while meeting applicable regulatory requirements.
• Apply AI‑assisted and data‑driven operational techniques to improve signal detection, reduce alert noise, accelerate root‑cause analysis, and surface opportunities for automation.
• Raise the bar for the team through thoughtful code reviews, documentation, knowledge sharing, and mentorship.
• Mentor and support team growth, fostering collaboration and scalability.
