Company Description

The Office of Innovation & Technology (OIT) is the central IT agency for the City of Philadelphia

headed by the Chief Information Officer. This position is within the OIT and assigned to the Department of Planning and Development’s (DPD) IT unit, which is responsible for the creation of spatial data and online web applications and tools to support community planning and housing strategies. DPD regularly engages with the public, city officials and a wide array of stakeholders using geospatial data and web applications to obtain input on the formulation of neighborhood, district and housing plans and to communicate the work of the department with the public. The Department of Planning and Development is made of up multiple divisions including Philadelphia City Planning Commission, Philadelphia Historical Commission, Art Commission, ZBA, Division of Housing and Community Development, and partners with the Philadelphia Housing Development Corporation.

The primary responsibility of this position is web-based application development for the divisions of the Department of Planning and Development (DPD) and its partner PHDC using industry-standard technologies and tools. This role involves working closely with the Office of Innovation and Technology (OIT), DPD stakeholders, and other City departments as required, overseeing the full software development lifecycle—from requirements gathering and design to development, implementation, and post-implementation support.

As a Software Engineer, you will work on both critical business systems and resident-facing applications, ensuring solutions are reliable, secure, and user-friendly. You will be primarily responsible for building APIs and UIs using our core technologies (.NET Core and Vue.js), while adhering to established City development standards and best practices. The role also requires contributing to technical documentation, testing, code reviews, and the maintenance of high-quality, scalable applications.

You will collaborate with cross-functional teams to solve complex problems, modernize legacy systems, and integrate with external data sources and services. Emphasis is placed on security, accessibility, and performance to support the City’s commitment to delivering efficient digital services for residents.

This is an opportunity to join a City government that operates the largest GitHub organization among municipalities (github.com / CityOfPhiladelphia), values open-source collaboration, and leverages modern cloud infrastructure to improve how residents and businesses interact with city government online. The position offers the chance to work in a mission-driven environment where your technical expertise directly contributes to the public good.
