Senior Frontend Engineer (Contract)

About Us

At Sully.ai, we’re building cutting-edge AI-native infrastructure to power real-time, intelligent healthcare applications. Our team operates at the intersection of high-performance computing, ML systems, and cloud infrastructure — optimizing inference pipelines to support next-generation multimodal AI agents. We're looking for a deeply technical Senior Frontend Engineer to own patient & staff web‑app UI implementation.

About The Project

Our client is a prominent outpatient behavioral health organization delivering psychiatry, counseling, and interventional services like TMS both in‑clinic and via telehealth. They operate multiple locations offering medication management for all ages, evidence‑based therapy modalities, and same‑day appointment options.

Patients use a secure web portal to access health records, message providers, request medication refills, and schedule appointments. New patients can request visits online and receive follow‑up within one business day. The staff dashboard must enable clinicians to review patient charts, manage AI‑generated notes, and oversee treatment workflows in a HIPAA‑compliant environment.

What You’ll Do

• Patient Portal Development: Implement React.js components for appointment scheduling, provider search, secure messaging, medication refill requests, and telehealth session booking.
• Staff Dashboard Implementation: Build administrative interfaces for clinicians to view/manage patient records, AI‑generated scribe notes, treatment plans, and TMS session tracking.
• AI Agent Integration: Collaborate with the AI platform to embed features such as automated intake triage and ambient clinical note‑taking (AI Receptionist and AI Scribe).
• API Development: Design and implement Node.js/Express.js endpoints for authentication, patient data CRUD operations, scheduling workflows, and secure data exchange with EHR systems.
• Type Safety & Shared Types: Define TypeScript interfaces for domain models (Patient, Appointment, Note) and enforce type consistency across front‑end and back‑end code.
• HIPAA Compliance & Security: Ensure all web‑app features meet HIPAA standards for data encryption, access controls, and audit logging.
• Collaboration & UX: Work closely with designers to translate Figma prototypes into responsive, accessible React components, and partner with QA to maintain high test coverage.

Qualifications

• 5+ years experience building production‑grade React.js applications.
• 5+ years experience developing RESTful or GraphQL APIs with Node.js/Express.js.
• Strong TypeScript skills, with understanding of structural type safety and shared type definitions.
• Familiarity with HIPAA requirements and building secure healthcare applications.
• Experience integrating third‑party authentication (OAuth, SAML) and EHR system APIs.
• Excellent communication skills and ability to work in a fully remote, cross‑functional team.

This Is For Someone Who

• Loves building from 0 to 1 (and then to 100).
• Can think in systems and move fast in chaos.
• Gets excited about real AI impact saving lives.
• Wants real ownership, is self driven and self-managed.
