We also believe that great work comes from people who feel trusted, supported, and aligned with the mission. Here’s how we try to make that happen:
Health Coverage
We offer medical, dental, and vision coverage for employees. For international contractors, we work closely to ensure access to appropriate local or global health coverage.
Flexible Time Off
We don’t track vacation days. Take the time you need to rest and recharge—we trust you to manage your schedule.
Remote-First by Design
Our team spans time zones and geographies. We work async, with a focus on autonomy over micromanagement.
Parental Leave
Paid leave is available for new parents, whether you’re the primary or secondary caregiver.
Learning & Development
We offer stipends to support ongoing learning - whether it’s a course, a conference, or something else that helps you grow.
We’re not here to build just another crypto project. We’re here to make DeFi usable, scalable, and meaningful. If that excites you, and you want to work with a group of people who care deeply about what they’re building - we’d love to talk to you.
