• 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, will make you understand how to write better, more supportable software, like no other experience.

• Own code quality, as we do early developer testing and functional/integration testing to ensure we build robust and resilient products.

• Partner with Product Management to review, refine requirements that exceed our customers’ expectations.

• Develop deep understanding of the fundamental problems our customers need solved through interaction with stakeholders and peers.
