The Staff Software Engineer, Backend role is responsible for designing, building, and maintaining the platform, services, and APIs that power AmaWaterways' consumer and partner digital products, from inception through implementation and ongoing maintenance. Working primarily within the .NET services backbone (Inventory Service, Leads pipeline, identity/auth, pricing, and supporting APIs), the Staff Software Engineer, Backend architects scalable, secure, and high-performance backend solutions and the integration patterns that connect booking, inventory, guest-experience, and partner systems. This role emphasizes strong platform engineering, RESTful and GraphQL API design, service and data architecture, and cloud-native delivery on Microsoft Azure. The Staff Software Engineer, Backend combines deep hands-on engineering with technical design ownership and mentorship, translating business and product requirements into robust technical designs while collaborating across engineering, QA, Product, and Platform Engineering teams. The role operates within an application engineering scrum team; specific team assignment will be determined based on portfolio needs at time of hire.

DUTIES AND RESPONSIBILITIES

• Design, develop, test, deploy, and maintain scalable, secure, and high-performance backend services and APIs (.NET / C#, RESTful and GraphQL) that support booking, inventory, pricing, lead capture, identity, and guest-experience use cases.
• Architect backend systems, services, and integration patterns, producing technical design documentation (TDDs), architecture diagrams, and decision records for new features and system improvements.
• Translate business and product requirements into sound technical designs, clearly communicating scope, effort, risk, and trade-offs to engineering and product stakeholders.
• Design and optimize data access and persistence layers, including relational database design, complex SQL, query performance tuning, and appropriate use of caching and NoSQL/data-layer patterns.
