• Automation Advocate: Advanced proficiency in Python, Go, or Bash, with a track record of building maintainable tooling that eliminates manual toil.
• Great Communicator: Exceptional skills in articulating complex technical concepts to both engineering peers and stakeholders, ensuring alignment on reliability goals.
• Analytical Architect: Apply a software engineering mindset to build, test, and maintain infrastructure code that ensures scalable and repeatable platform provisioning. Hands-on experience with modern declarative ecosystems like Pulumi, Crossplane, or similar tools is highly preferred.
• Collaborative Mentor: Strong ability to influence architectural decisions across teams while motivating and growing the technical skills of junior engineers.
• Compliance Conscious: Experience operating in regulated environments (HIPAA, ISO, or medical device) is a significant plus.
