Senior DevOps/SRE Engineer
About the role
We are looking for a Senior Site Reliability Engineer to join our lean, product-focused engineering organization. This role involves building and operating reliable cloud-based systems, collaborating with product and application engineers, and using modern tools to improve efficiency and reliability.
Responsibilities
Design, build, and operate cloud infrastructure for critical production and non-production applications with reliability and simplicity as primary goals.
Architect and evolve multi-account AWS foundations (organizations, accounts, IAM boundaries, guardrails, and environment separation) to enable secure, scalable delivery.
Design and operate cloud networking architecture (VPCs, routing, segmentation, ingress/egress, connectivity patterns) to support reliability, security, and compliance requirements.
Treat reliability, security, and compliance as first-class design concerns throughout the system lifecycle.
Build tooling and automation that reduces errors, shortens recovery time, and improves day-to-day operations.
Implement monitoring, logging, and alerting that make system behavior observable and actionable.
Use AI-assisted tools to accelerate infrastructure delivery, automation, troubleshooting, and root-cause analysis, applying engineering judgment to validate outcomes.
Implement reliability guardrails for releases (progressive delivery, safe rollbacks, change risk controls) and provide production support during deployments.
Participate in incident response, perform root cause analysis, and drive durable improvements that prevent recurrence.
Work closely with application engineers to co-own system design, operation, and continuous improvement.
Maintain clear, lightweight documentation that supports shared ownership and effective on-call operations.
Requirements
Bachelor's degree in a related technical field; or the equivalent in education and work experience.
8+ years of experience in DevOps, SRE, platform engineering, or similar roles supporting application teams running production services.
Strong CI/CD experience (Jenkins and Git-based workflows preferred), including building secure, reliable pipelines and enabling teams to ship safely.
Hands-on, demonstrable experience implementing and operating observability platforms (logging/metrics/alerting); Elastic Stack/OpenSearch experience is a plus.
Infrastructure as Code experience (Terraform preferred; CloudFormation acceptable), including building reusable modules/patterns and managing changes through review and automation.
Experience scripting in Bash, Python, or PowerShell.
Experience supporting CI/CD builds and deployment patterns for common application stacks (for example Java, NodeJS, and .NET).
Qualifications
Ability to clearly communicate both verbally and in writing with client and team members, including experience documenting and presenting findings.
Excellent analytical skills, organizational abilities, and problem-solving skills.
Familiarity with AI agentic development tools (e.g., Claude Code, GitHub Copilot, Windsurf) and practical experience applying them to infrastructure and operations workflows.
Self-starter who works efficiently in a fast-paced environment with changing priorities and a geographically distributed team.
Ability to think creatively and seek optimum solutions.
Diagnostic skills with the ability to analyze technical, business and financial issues and options.
Willingness to understand how an application is put together and the ability to infer from previous examples, transform them into tangible results and key deliverables.
Action-oriented, with the ability to quickly deal with change.
Someone who will embody our SEI Values of courage, integrity, collaboration, inclusion, connection and fun.
