Software Developer, Software Engineer, Backend Developer

This is a mid-level role on our Technology Solutions team. The position's objective is to develop, maintain and modernize the agency's internal management platforms to support media, creative and client services workflows. This role will work closely with our Principal Engineer, Media Systems, with an initial focus on maintaining and evolving a legacy .NET WPF desktop application backed by Microsoft SQL Server, and an eventual focus on supporting and extending our newer React/Type Script web platform and Graph

QL API and other projects.

While eventually a largely remote role, this person is initially expected to work from our Portland office with our staff engineer and other members of the team a few days per week or month for onboarding purposes.

At this time, we are not considering candidates outside of the Portland, Oregon Metro area.
