Note: The job is a remote job and is open to candidates in USA. Circle is one of the world’s leading internet financial platform companies, building the foundation of a more open, global economy through digital assets, payment applications, and programmable blockchain infrastructure. As a Senior Site Reliability Engineer, you will design, build, and operate the secure, scalable platform infrastructure behind critical digital-assets and application workloads.
Responsibilities
- Design, build, and operate Kubernetes platforms that provide secure, highly available, and scalable foundations for critical production services across hybrid and public-cloud environments
- Build 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
Skills
- 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
- Production software-development experience in Go, Python, or JavaScript/TypeScript, with the ability to build maintainable backend services, tooling, and automation—not only scripts
- Demonstrated success improving the reliability, performance, scalability, or cost efficiency of distributed systems in production
- Experience with cloud infrastructure and core networking concepts, including IAM, DNS, load balancing, routing, service networking, and secure connectivity
- Strong observability and troubleshooting skills using metrics, logs, traces, alerting, and incident data to diagnose complex systems
- Experience defining and operating against SLIs, SLOs, error budgets, incident-management processes, postmortems, and disaster-recovery practices
- Familiarity with CI/CD, GitOps or deployment automation, and safe rollout strategies such as canary or blue-green deployments
- A security-minded approach to infrastructure and a track record of partnering effectively with Security and engineering teams in regulated or high-availability environments
- Clear written and verbal communication, strong ownership, and the judgment to balance speed, risk, and operational excellence
- Experience applying AI-assisted tooling to engineering or operations workflows is a plus
