Develop tools to automate engineering workflows. Ensure uptime, reliability, and effective troubleshooting through observability and operational support. **Cloud Infrastructure & Management**: Design, build, and manage scalable, secure software and infrastructure in Kubernetes environments across AWS, Azure, or GCP. Use Crossplane for multi-cloud resource management. Implement Infrastructure as Code using Terraform, CloudFormation, and Helm. You'll serve as a role model and mentor to other engineers, making key technical decisions and improvements while shipping and iterating on a weekly basis to prepare the product for GA. **Requirements**: 8+ years shipping production-level software; strong foundation in Node.js and/or Golang; proven track record delivering impactful projects independently and as part of a team; hands-on experience with Kubernetes and cloud infrastructure APIs; deep commitment to test-driven development and operational excellence. **Nice-to-have**: Experience contributing to 0-to-1 products; background with developer tools or technical products; familiarity with Serverless or PaaS developer tools.
