Life at OneRoof

Joining OneRoof is more than just a job.

We are bringing world’s largest social asset, community, in the world’s largest asset class, residential real estate.

Urban living has become more crowded yet more disconnected than ever, residents’ voices are being silenced by operators, and the only real interactions are those that escape beyond awkward eye contact in the elevator.

Connecting neighbors builds unity, empowerment, a support system, and a sense of belonging at home, where people predominantly spend their time.

We believe that over the next decade, residential buildings will be founded on social interactions, where the people are just as important as the space, where resources are shared, interests are aligned, and asset value fluctuates multidimensionally, including social bonds.

OneRoof is redefining how we live in a connected, unified, and empowered way in our built environment.

🚀 Are you ready to build the largest hyper-local network?

We’re looking for an individual with crazy motivation to build the largest hyper-local network in the world with us. If that sounds like you, email with your resume, portfolio, and why you’re the best fit for this role. We’ll be on the lookout!

At OneRoof, we strive to build diverse teams that reflect the people we want to empower through our products, and we are committed to equal employment opportunity regardless of race, national origin, color, gender identity, sexual orientation, religion, age, or disability.
