• Write code in Go and work with data pipeline using SQL or other interfaces. Leverage Kubernetes for service infrastructure platform. Welcome people with backgrounds in other languages and technology stacks along with a desire to learn.
• Own critical features and subsystems and own the entire software development lifecycle, from clarifying requirements to ensuring their successful deployment and usage by customers.
• Own operational aspects of the system, being on the front lines and experiencing first‑hand the challenges of operating such a system, to understand how to write better, more supportable software.
• Own code quality, early developer testing and functional/integration testing to ensure we build robust and resilient products.
• Partner with Product Management to review, refine and set product goals and objectives that exceed our customers’ expectations.
• Develop deep understanding of the fundamental problems our customers need solved through interaction with stakeholders and peers.
