Responsibilities

• Own solutions from problem to production. Work with product managers and engineers to understand partner needs, shape the approach, and design, build, test, and operate backend services.
• Make thoughtful technical decisions. Explain tradeoffs clearly and balance delivery time, reliability, and maintainability, including when the information available is incomplete.
