Castle is leading the way for companies to better protect their online accounts. Our customers protect millions of consumers every day. We challenge ourselves at Castle to think and work differently because ultimately our solutions help protect you, and your friends and your family. Join us on the journey.
Benefits and perks
We trust you to take time off when you need it. Focus on producing great results, rather than just putting in the hours.
Save money on any expenses related to traveling to and from work. We offer a tax-exempt program to help you get around.
We cover your health insurance premiums at 100% with gold and platinum plans, and offer coverage options to your dependents as well.
We offer a variety of tax-exempt retirement plans with matching so our colleagues can start planning now for retirement. Security is really important to us!
A lot of us have families, of all shapes and sizes, and we welcome each new addition with a longer-than-standard parental and new child bonding leave for series A startups.
Fika and Breakfast
We share catered breakfast together on Monday mornings, and ease into the weekends with Swedish Fika - a relaxing coffee and cake break.
