Senior Software Engineer, Platform

The Senior Software Engineer on the Platform team will design performant foundational systems and developer integration tooling supporting our other backend software engineering teams: API, internal services, and data science. The Platform team's solutions better enable these teams to rapidly develop mission-critical solutions and applications for our customers and for our operations & supply chain teams, with greater consistency, performance, security, operability, and maintainability. 

They will work closely with the DevOps team to enable reliable infrastructure, effective automation, and self-service. They rely on their own experience while performing additional research as necessary, to arrive at the best solution for each task. They have proven records being the tech lead on complex, cross-team projects, proactively raising issues, and resourcefully unblocking themselves to ensure projects are delivered with high quality and within the expected timeline. They can constructively debate any issue, persuade others with hard evidence while staying objective and open to changing their mind. In short, they will support the foundation of our entire engineering team’s continued success.
