• Proficiency in Go and experience with Terraform, protobuf/gRPC and REST design
• Strong understanding of cloud computing infrastructure using Kubernetes, scalable architectures, and automation
• Strong communication and leadership skills; track record of delivering cross-organizational initiatives as the technical lead
• Excellent analytical and problem-solving skills, with the ability to synthesize problem statements from interactions with customers and design solutions given ambiguous requirements
• Solid grounding in CI/CD, testing strategies, and safe rollout/deprecation practices for API changes
• Prior contributions to Terraform providers or similar IaC tooling, including registry distribution, versioning, and upgrade guidance
• Strong observability skills (metrics, logs, tracing) and practical experience defining API SLIs/SLOs
• Wondering if you’re a good fit? We believe in investing in our people, and value candidates who can bring their own diversified experiences to our teams – even if you aren't a 100% skill or experience match
