Our mission is to enable individuals and organizations to radically improve their decision-making by sharing the unique tools and principles that our founder, Ray Dalio, used to build Bridgewater Associates  out of his two-bedroom apartment into one of the most successful companies in the world.

 Everything we do is based on the core belief that the best decision-making system is an idea meritocracy—one that helps identify the best ideas by encouraging and surfacing independent thinking and thoughtful disagreement.

 Our principles, tools, and systems help individuals and organizations cultivate their own idea meritocratic decision-making. They do this by building a deep understanding of people’s strengths and weaknesses to maximize individual and team potential, by enabling a culture of radical truth and radical transparency, and by providing expert algorithms to aid key decisions in work and life.

This team will join our existing infrastructure and platform engineering teams and will be responsible for defining and introducing best practices with the latest technologies for UI development.

You’ll be building a suite of multi-tenant SaaS products to help our customers understand what they and their coworkers are like, and how to leverage that information to make better decisions

Voluntary Self-Identification of Disability

Why are you being asked to complete this form?

We are a federal contractor or subcontractor required by law to provide equal employment opportunity to qualified people with disabilities. We are also required to measure our progress toward having at least 7% of our workforce be individuals with disabilities. To do this, we must ask applicants and employees if they have a disability or have ever had a disability. Because a person may become disabled at any time, we ask all of our employees to update their information at least every five years.

Identifying yourself as an individual with a disability is voluntary, and we hope that you will choose to do so. Your answer will be maintained confidentially and not be seen by selecting officials or anyone else involved in making personnel decisions. Completing the form will not negatively impact you in any way, regardless of whether you have self-identified in the past.
