Requirements
• Bachelor's in Computer Science, Engineering, related field, or equivalent practical experience • Expert-level experience (5+ years) managing medium to large-scale deployments on AWS (~5000 instances, 50+ accounts), or equivalent. • 3+ years of experience programming in Java, Python, or other formal programming languages • Understanding of container orchestration and microservices • Experience with service discovery/service mesh • Strong Linux administration experience, shell/bash scripting. • Expert-level experience with Infrastructure as code tools: Terraform, CloudFormation; config management/provisioning tools: Ansible, Chef, etc. • Strong Build / Automation / CI/CD experience. • Strong Knowledge/experience with networking and load-balancer technologies. • Experience with existing open-source projects such as Consul, Docker, ArgoCD, Nexus, Jenkins • Experience with large-scale Kafka deployments • Database knowledge is a plus. • Excellent troubleshooting skills, expertise with any monitoring tools, and attention to detail • Excellent interpersonal skills and highly collaborative working style • Hands-on experience with AI coding tools (Claude Code, Cursor, or equivalent) used for infrastructure scripting, incident response automation, or tooling development • We value having a diverse and inclusive community from many backgrounds, so even if you don’t meet 100% of the above qualifications, you should still seriously consider applying! • AI-Native Expectations • We use AI coding tools as a professional standard on this team. Here's what that means in practice: • Daily use: You use AI coding assistants (we support Claude Code, Cursor, and GitHub Copilot) for real, substantive tasks: analysis, coding, refactoring, testing, navigating codebases, and documentation. Not just research or autocomplete. • Daily use: • Judgment and ownership: AI-generated code gets the same review you'd give any PR.

You don't need to have built a production agentic system, but you should be curious about this space, have opinions on where it works and where it breaks, and be ready to contribute to it. • Agentic thinking • Velocity: We expect senior engineers who use AI well to operate with meaningful leverage — doing more with the same time, taking on problems that would otherwise require a larger team. • Velocity: • Team leadership: You share what works. You automate prompting strategies that others can build on. • Team leadership: • Continuous learning: The tooling is changing fast. You stay current and bring recommendations to the team. • Continuous learning:
