The developer will support web and mobile applications used by researchers and clinicians at the National Institute of Allergy and Infectious Diseases (NIAID) in the National Institutes of Health (NIH). This opportunity is a full-time position with Guidehouse and can be remote or on-site at NIH in Rockville, MD.

Periodic onsite presence is required, including in‑person new‑joiner orientation in Tysons Corner, VA and occasional onsite team meetings in Rockville, MD. The Senior Software Developer will collaborate closely with PhD-level scientists and subject matter experts to translate complex scientific workflows into reliable, scalable services and to design user interfaces that make complex scientific data and workflows accessible and actionable. Responsibilities include designing and implementing APIs, data processing pipelines, and computational services, developing reusable React components, integrating with APIs, ensuring performance and usability at scale, contributing to system architecture, writing well‑tested, maintainable code, and mentoring other developers.

Experience with scientific computing libraries, data‑intensive workloads, or distributed systems is highly desirable. Applications developed by the team are used in clinical and research settings and development is driven by continued use and iterative feedback from researchers and clinical staff as well as subject matter experts and software development team members.
