The developer will be part of a small, focused product team, reporting to a Principal Developer and working alongside a Senior Full Stack Developer (front-end focus) and a Product Owner. This role is ideal for an experienced backend engineer who wants meaningful ownership of core services and data architecture, exposure to complex business workflows, and the opportunity to keep growing technically within an established team structure. This role works across both legacy and modern software patterns. Part of the job is understanding and maintaining older C# codebases alongside building new services and integrations. Expect the majority of your time on new services and integrations, with legacy C# maintenance as a recurring but secondary part of the work. Houston, Texas preferred. Remote available.

• Support responsive, mobile-first UI work across desktop, tablet, and mobile devices.
