About the role

Posted May 20, 2026

Security Engineer

Build the future of investment management with us

The infrastructure managing $300 trillion in assets was built in the 90s. Now, all of it is up for grabs. The winner of the AI era of investment management will be a $100B+ company. We intend to be that company.


To get there, we're assembling the most talent-dense startup in New York. We hire people who are 1) exceptional, 2) allergic to anything that's not exceptional, and 3) recruiters of other exceptional people. We also have no tolerance for brilliant jerks.


We run lean by design. We work with a select group of the largest financial institutions in the world, go incredibly deep with each, and sit in the flow of trillions of dollars. We hire fewer people, ask each to own the outcome, and pay on impact - not tenure or experience.


Moment is not for everyone. The standards are unreasonably high. The pace is intense. And there is no playbook.


In return: the best work of your career, building a generational company.
