Tomorrow Health connects patients, providers, health plans, and home-based care suppliers, to ensure patients receive the correct and timely care they need to remain healthy at home.

The Team

The Engineering team at Tomorrow Health builds the technology that connects and scales the home health ecosystem in order to transform the home into the preferred place of care for positive patient outcomes. Our products serve a diverse set of users – doctors, insurance companies, medical equipment suppliers – and ultimately enable us to deliver a higher quality patient experience.

  • Comfortable with AWS or similar cloud infra
  • Familiarity with frontend stack: React, TypeScript, Node.js
  • Strong cross‑team communication; able to simplify AI concepts for non-technical stakeholders
  • Passion for mentoring, engineering standards & excellence
  • Experience in fast / ambiguous environments; willing to own projects end to end
  • Alignment with mission: improving home‑based health care via technology

Benefits

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
