• Architect applications using Kubernetes controllers, operators, and distributed systems patterns
• Provide subject-matter expertise in Go development for infrastructure APIs, orchestration layers, and platform components
• Build and maintain highly available production systems designed for reliability and observability
• Mentor engineering teams and foster a culture of knowledge sharing and continuous improvement
• Partner with product development teams to understand requirements and co-design solutions that serve their needs
• Participate in on-call rotations to ensure business-critical systems receive prompt, effective responses

Who We're Looking For

• 10+ years building and operating cloud infrastructure or backend systems at scale
• 4+ years of experience leading technical initiatives from conception through successful delivery
• Expert-level proficiency in Go, particularly for building infrastructure APIs and cloud orchestration tools
• Deep knowledge of Kubernetes architecture and cloud-native design patterns, including operators and controllers
• Proven track record designing and running production applications built for high availability
• Strong foundation in Linux operating systems and systems engineering principles
• Hands-on experience with GCP, distributed systems architecture, and site reliability practices
• Demonstrated skill with infrastructure observability and tuning, particularly Datadog
• Experience with Temporal workflow orchestration (a plus)
• Genuine interest in teaching others and elevating team capabilities through knowledge transfer
• Comfortable working directly with internal stakeholders to understand needs and co-develop solutions
• Authorization to work lawfully in the United States; Calendly does not provide immigration sponsorship
