SUMMARY

This position is a senior backend engineering role 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 Senior Software Engineer architects scalable, secure, and high-performing 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 Senior Software Engineer 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.
• Build and maintain secure, well-documented APIs and service contracts, with attention to versioning, error handling, caching, observability, and secure data flows across internal and external systems.
• Integrate backend services with external data sources, partner systems, and identity/access management platforms, ensuring reliable and secure data exchange.
• Optimize services for scalability, throughput, and low-latency performance, and support production reliability through monitoring, logging, telemetry, and alerting.
• Establish and uphold engineering standards for code quality, security, performance, observability, and incident response across owned services.
• Conduct and participate in code reviews, enforce branching and pull-request workflows, and uphold the team's Definition of Ready and Definition of Done tied to CI/CD gates.
• Perform root-cause analysis, troubleshooting, and escalation for production issues and incidents; participate in on-call rotation as required.
• Provide effort estimations and delivery commitments in support of roadmap planning and sprint execution.
• Provide mentorship and technical guidance to mid-level and junior engineers on coding standards, architectural patterns, and backend best practices.
• Champion automation and modern solutions, including the appropriate use of AI-enabled development tools and AI-powered capabilities, where they improve quality, velocity, and reliability.
• Partner with QA, Product, UX/UI, and Platform Engineering to deliver iterative, high-quality releases in an Agile/Scrum environment.
• Stay current with emerging backend technologies, cloud services, API and identity patterns, security standards, AI tooling, and development practices, and evaluate their applicability to AmaWaterways.
• Contributes to and maintains technical documentation such as design specifications, API documentation, and system documentation.
• Performs other related duties as assigned by management.
