About The Position

Estrada Consulting, Inc. is seeking an experienced ArcGIS web application developer to build a public displacement dashboard in a public-sector transit client’s ArcGIS Online environment. The dashboard will present the results of a regional analysis of household moves around transit stations and corridors over a twenty-year period, helping agency staff, partner agencies, and community members understand where displacement pressure is building and what the data shows. The application will use hosted feature layers, ArcGIS Experience Builder, and an ArcGIS StoryMap for key takeaways. The developer will configure and extend the Experience Builder application, create a printable one-pager and accessible data table view, and help ensure the product meets WCAG 2.1 Level AA. The solution must be maintainable by client staff after handoff. All code, configuration, and documentation will be delivered to the client, including a documented ArcGIS API for Python script that client staff can run annually to load new results. The engagement is remote and limited to US-based team members. It is estimated at about 430 hours over five months, roughly 20 hours per week, contingent on contract award. Regular video meetings with the client’s project team, analysis partner, and steering committee are scheduled on Central time. The expected start is early 2027. The hourly rate is $50 to $80, depending on experience. Candidates must consent to a basic background check, and their name and resume summary will be included in ECI’s proposal.
