About HealthJoy

Let’s keep things simple: we are an unbelievably talented, hard-working, and compassionate team driving towards a mission that impacts every single one of us - even you! Healthcare benefits are complex, underutilized, and a mystery for most users. We’re removing that complexity.

Our industry-leading technology solution puts a simplified benefits experience in the hands of users, saving them time and money. Since the start of the pandemic, we’ve created a COVID-19 resource center, helped members find testing and care, and made it even simpler to get telemedicine and mental health support to employees.

HealthJoy experienced explosive growth in 2020: we raised $30M in Series C funding, earned awards for Talent Culture’s Best HR Technology Leaders and Built In Chicago’s Best Places to Work, added 55+ key team members despite going totally remote, and so much more. This year, we continue down that path of high growth and high impact.

**Our rewards**
Work should be meaningful and rewarding.

HealthJoy offers a robust package of employee perks and benefits including competitive compensation, unlimited vacations, health insurance, English lessons with a native speaker and full or partial coverage of educational events.

During the pandemic situation we offer mental health support programs, personal psychological counseling and help with remote work setup.

We also enjoy each other's company over wellness activities, happy hours, volunteer events in our local communities, lunch and learns, and ‘friendship time’ pairings.

HealthJoy is committed to creating a diverse environment and is proud to be an equal opportunity employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, gender, gender identity or expression, sexual orientation, national origin, genetics, disability, age, or any other basis forbidden under federal, state, or local law.
