Job Title : Sr. Web Backend Developer

Location : Alexandria, VA Onsite

Duration : Long-Term

Start Date : November 15, 2026

Interview Type : In-Person

Project : Digital Modernization

Project Overview: Web Modernization and SmarTrip Mobile App 2.0

The organization is currently executing two strategic digital modernization initiatives: the Web Modernization Project and the SmarTrip Mobile App 2.0 Project. Both projects are actively underway and are critical to enhancing the customer experience across digital channels.

The Web Modernization Project involves the complete redevelopment of the front-end experience for the organization's primary website and SmarTrip website, replacing the existing platform that was last significantly refreshed in 2016. While a separate vendor is responsible for the website front-end implementation, backend development resources are required to develop, integrate, test, and deploy the supporting SmarTrip backend services and APIs necessary to enable the new website functionality.

The modernized platform will continue to serve as the primary digital channel for transit information, customer self-service capabilities, and SmarTrip account management.

The SmarTrip Mobile App 2.0 Project focuses on enhancing the existing iOS and Android mobile application by introducing new features and improvements designed to provide a more personalized, intuitive, and user-friendly customer experience. Support is required for application integration, development, configuration, testing, deployment, and production implementation of the backend components that support the mobile application and related services.
