The San Francisco Municipal Transportation Agency (SFMTA) is a department of the City and County of San Francisco responsible for the management of all ground transportation in the City. The SFMTA has oversight over the Municipal Railway public transit (Transit Division or “Muni”), as well as bicycling, paratransit, parking, traffic, walking, and taxis. SFMTA is currently in the process of implementing an upgrade of the technology used to manage light rail operations on the surface and in the subway. Position Description: The Train Control Upgrade Project (TCUP) is a multi-year, multimillion dollar project with the goal of replacing the existing train control system onboard vehicles and in the Muni Metro subway with a state-of-the-art radio-based technology. TCUP will expand supervision of trains by the train control system from the subway to the entire surface Muni light rail system. The TCUP vendor contract and installation work will be managed by a project management team within the Transit Division (“Muni”). Information Technology is at the core of TCUP. SFMTA’s Technology Solutions and Integration (TSI) team will be delivering the technology scope for TCUP.  The role will be supporting delivery of the information technology components. Success requires significant investments in expanded network infrastructure, data architecture, wireless communication systems, servers, databases, and cybersecurity. Project systems will need data integration with existing enterprise and intelligent transportation systems. Changes need to be baselined, documented, designed, implemented, and tested. This is an opportunity to work with stakeholders and business units across the SFMTA and take a pivotal step in your career. Your work will impact the lives of all users of our transportation services and infrastructure.   Examples of Important and Essential Duties: Collaborate with stakeholders, vendors, project teams, and operational personnel to define requirements, coordinate testing activities, and resolve integration issues.

Configure and test APIs, middleware, and messaging systems. Analyze, troubleshoot, and resolve integration issues across enterprise and operational technology platforms with minimal disruption to system performance. Implement version control and change management processes. Develop and execute integration, performance, reliability, and end-to-end test plans and test cases, including validation of failover and error-handling scenarios. Support deployment, commissioning, operational readiness, business continuity, rollback planning, incident response, and post-deployment stabilization activities for mission-critical transportation systems. Review and evaluate vendor-provided designs, interface specifications, test results, and technical deliverables for compliance with project requirements and agency standards.
