Senior Software Engineer, Astronomer

• 5+ years of experience in infrastructure, platform, or systems engineering, with a track record of owning production systems at scale (8+ years typical for Staff)
• Deep, hands-on expertise with Kubernetes, including building custom Operators/CRDs and managing Helm-based deployments for infrastructure lifecycle workflows
• Experience designing APIs (REST or gRPC) that serve as the core engine behind a customer-facing UI or programmatic integrations, including versioning and backward compatibility
• Strong systems fundamentals: networking, distributed systems, reliability engineering, and security best practices
• Proficiency in Go and/or TypeScript, or a demonstrated ability to pick up new languages quickly
• Practical experience designing and/or building observability and distributed tracing for multi-layer systems
• Demonstrated ability to lead technical design across teams and communicate trade-offs to both engineers and stakeholders
• Experience mentoring engineers and improving team-wide practices

Desirable

• Senior and Staff Software Engineers on our Infrastructure team own the architecture of the systems that stand up, configure, and manage the infrastructure the underlying Airflows run on
• This includes the security of those systems and the reliability and observability capabilities that keep Astro running at scale, across both Astronomer's multi-tenant cloud platform and Astro Private Cloud, our self-hosted distribution for regulated organizations running Airflow in their own private clouds or fully isolated data centers
• You'll design and build the control-plane services, the APIs that drive infrastructure lifecycle management, and the control/data-plane interaction patterns that make it possible to bring up and manage that infrastructure — including how those interactions hold up across network topologies from standard private cloud to zero-egress, air-gapped environments
• You'll bring deep, hands-on expertise in distributed systems, API design, and infrastructure lifecycle management, own the technical direction, design, and implementation of key areas of the platform, and mentor engineers earlier in their careers
• This posting covers both Senior Software Engineer and Staff Software Engineer, with the level you're hired at depending on experience and demonstrated scope
• Design and own the architecture of the systems that stand up, scale, and manage the infrastructure Airflow runs on, leading these efforts end-to-end (design, implementation, tests, documentation, and rollout)
• Design and evolve the APIs (REST/gRPC) that drive infrastructure lifecycle management, powering customer-facing UI and programmatic integrations, including data modeling, versioning, and backward compatibility
• Own the networking and security posture of these systems, including how they authenticate, authorize, and communicate securely, and drive CVE remediation, image hardening, and Pod Security Standards compliance
• Architect observability and traceability across the stack: metrics, logs, and traces that let a request be followed end-to-end across service and network boundaries
• Participate in on-call rotation, contributing to incident diagnosis, resolution, and post-mortems for these systems and ensuring remediation items are tracked into sprints
• Mentor engineers and raise the bar on design and code review, testing, and operational rigor
