humankind’s greatest challenge. If an uncommon answer to a very common question
intrigues you, please continue reading.

Culture & Values

We strive to create an environment where employees can grow personally and thrive professionally.

It's not what we do, it's how we do it

We are problem solvers. We embrace adversity and seek to solve the almost impossible. Above all, we are mission-driven technologists on a mission to build planetary-scale resilience, together.

Our Values

We own the mission

We’re laser focused on our mission. We radically prioritize the work that makes the biggest impact.

We go beyond

We drive the business to the limits of its potential and never settle for mediocrity in ourselves. We have a bias toward action and always take our best shot.

We build trust

We leave our egos at the door. We work across aisles and have each other’s backs.

We become better together

Alone we have limitations, together we have solutions. We have the humility to seek dissenting opinions.

Global resilience can only be built by a global team

We’re a Virtual First company, which means remote work is the norm at One Concern, allowing us to build a team that spans the globe. Already our employees represent 5 continents and more than 20 countries, and true to our values, we’re constantly working to improve as an organization – to make One Concern a more diverse, equitable, and inclusive place to work.

"I wouldn’t say I have all the answers; my team has all the answers"

A Virtual First Company

Not content with the either or choice of returning to the office or not, One Concern champions a Virtual First model that establishes remote work as the norm, but also brings the company together regularly for in-person retreats and celebrations. Virtual First bolsters the diversity of our organization by allowing us to hire outside of Silicon Valley, while also catering to employee preferences for a commute-free future that allows for greater productivity and more time with family and loved ones.

Perks & Benefits

Due to the COVID-19 pandemic, One Concern offices in Menlo Park and Tokyo are currently closed.


Resilience starts with you. We offer comprehensive dental, vision, and life insurance, up to 100% health coverage for large network plans across the U.S. as well as free access to a primary care practice, offering both virtual and in-person appointments within 24 hours.


You’re at your best when you’re rested and energized. To make sure we’re caring for both body and mind, we offer a generous monthly wellbeing reimbursement as well as unlimited vacation. Life is about more than just work, we encourage you to take time off whenever you need it.

Work/Life Balance

Life can make keeping a regular schedule a challenge. As a Virtual First company, we’re used to working across multiple time zones, so are committed to flexible working hours to help you manage and balance your personal & professional obligations wherever you may be.

Competitive Salary & Equity

Own the work you do. We offer competitive compensation packages and equity stakes in the company.

Best of Both Worlds

Remote work is the norm for us, but in-person connection is important too. That's why we come together multiple times a year for retreats and events at our offices in Menlo Park, CA and Shibuya in downtown Tokyo.

Home Office Support

In addition to all the tech you need to work to your best, we provide a $300 pre-tax stipend when you join to help you make the purchases you need to be successful in your home office.
