Job: Senior Full Stack Engineer

About Our Client

Our client is transforming the chaotic back office of U.S. healthcare with AI and automation. Today, many clinics are overwhelmed with faxes, manual forms, long insurance calls, and administrative headaches. Our client company simplifies it all—automating intake, insurance verification, documentation, and patient calls—so clinics can focus on care, not paperwork.

• Manage messy, real-world healthcare data pipelines with grace and resilience.

• Deploy the product within Clinics & Leading Healthcare providers across US.
• Collaborate directly with founders, product, and customers to design and launch mission-critical features.
