Description de l'entreprise

With a workforce of over 25,000 people, and opportunities in more than 1,000 different job categories, the City of Philadelphia is the fifth largest city in the United States and one of the largest employers in Southeastern Pennsylvania. As an employer, the City of Philadelphia operates through the guiding principles of service, integrity, respect, accountability, collaboration, diversity and inclusion. Through these principles, we strive to effectively deliver services, to resolve the challenges facing our city, and to make Philadelphia a place where all of our residents have the opportunity to reach their potential.

The Office of Innovation & Technology (OIT) is the central IT agency for the City of Philadelphia headed by the Chief Information Officer (CIO). OIT oversees all major information and communications technology initiatives for the City of Philadelphia - increasing the effectiveness of the information technology infrastructure, where the services provided are advanced, optimized, and responsive to the needs of the City of Philadelphia's businesses, residents, and visitors.

OIT responsibilities include: identifying the most effective approach for implementing new information technology directions throughout city government; improving the value of the city's technology assets and the return on the city's technology investments; ensuring data security continuity; planning for continuing operations in the event of disruption of information technology or communications services; and supporting accountable, efficient and effective government across every city department, board, commission and agency.

The Revenue IT team builds and supports critical tax and revenue systems that power how the City serves residents and businesses. We're a small, highly collaborative engineering group that partners closely with our vendor, FAST, to configure and extend the City's Gen Tax platform and surrounding services. You'll work across the stack-owning features end‑to‑end, from discovery and design through development, testing, deployment, and production support-while contributing to shared standards and modern engineering practices across OIT.

You'll collaborate with product owners, business analysts, QA, and stakeholders in the Department of Revenue, and coordinate frequently with FAST engineers to deliver reliable, secure, and well‑documented solutions.
