Mid-Level Full-Stack Engineer — Front End & UX

About

We are looking for a mid-level full-stack engineer with a strong front-end and UX sensibility to help modernize the user-facing layer of a mission-critical clinical research platform. You will partner with the senior engineer to deliver role-centric, intuitive interfaces for clinical coordinators, nurses, ODQ staff, investigators, and administrators across the Harvard Cancer Center consortium.

Requirements

• 3–5 years of professional software engineering experience
• Solid C# and .NET Core proficiency — comfortable building and consuming REST APIs
• Strong front-end development skills: modern JavaScript/TypeScript, component-based UI frameworks (React, Angular, Blazor, or equivalent)
• Demonstrated UX sensibility — experience translating wireframes into polished, accessible interfaces
• Familiarity with drag-and-drop UI patterns, multi-select workflows, and inline validation
• Experience with responsive design and WCAG accessibility standards
• Comfortable working with RESTful APIs and understanding of full-stack data flow
• Experience in collaborative Agile/Scrum delivery environments

What you'll do

• Implement UX wireframes and prototypes for priority management, bulk publishing workflows, and role-based dashboards in collaboration with UX specialists
• Build the front-end layer of the modernized OncPro platform — including filterable/grouped priority list views with drag-and-drop ranking, inline PDF preview with consent stamp overlays, and ODQ queue-focused and Nursing-specific workspaces
• Develop and consume C#/ASP.NET Core APIs to support UI features — full-stack ownership of features from back end to browser
• Implement 'current-only' assurance banners, inline validation, and confirmation workflows for bulk operations (publish, replace, ignore)
• Contribute to API/contract testing and front-end integration testing across the OncPro ecosystem
• Ensure accessibility compliance across all UI components
• Collaborate with QA/BA on test case development and UAT support for ODQ, Nursing, and provider stakeholders
• Contribute to documentation and knowledge transfer materials to support long-term DFCI ownership
