You will work across the stack—from infrastructure automation to observability, IaC evolution, and CI/CD improvements—primarily using Python, Go, and AWS. Strong leadership and collaboration with security and software teams are essential.

Qualifications

• 6+ years of experience in SRE, DevOps, Cloud Engineering, or Software Development roles.
• Hands-on experience operating production environments in AWS.
• Proficiency in Go or Python, with experience building production-grade automation, tooling or libraries.
• Strong experience with Terraform.
• Experience with container orchestration platforms like ECS or Kubernetes.
• Familiarity with CI/CD tools such as GitHub Actions.
• Experience designing and implementing re-usable platform components based on team requirements.
• Solid understanding of observability practices including system metrics, distributed tracing, and SLOs.
• Exposure to failure-based testing approaches and automated recovery strategies.
• Strong leadership and communication skills, both written and verbal.
• Experience evangelizing reliability best practices.

Responsibilities

• Infrastructure Automation: Design, build, and scale production environments using AWS and Terraform, driving architectural decisions that improve long-term maintainability and reliability.
• System Reliability: Lead efforts to improve platform resilience through failure-based testing, automated recovery strategies, and proactive capacity planning.
• Developer Enablement: Own the design and delivery of reusable platform components and self-service tools that streamline the developer experience and reduce cross-team toil.
• Observability: Define and evolve observability standards across the platform, including system metrics, distributed tracing, and SLO frameworks.
• Project Ownership: Own projects end to end—from initial scoping and effort estimation through detailed planning, execution, and successful rollout.
• Mentorship & Standards: Mentor engineers across the team, uphold high infrastructure quality, and actively shape the best practices and standards used by the organization.
• Collaboration: Engage in technical design discussions, providing guidance and feedback while adapting strategies based on team input and evolving requirements.
• On-Call: Participate in a low-volume on-call rotation.
