San Francisco, United States Caldera Full time
Senior Infrastructure Engineer, Security

We're looking for an incredible senior engineer to help us build the future of blockchain scalability.

This is an ideal opportunity for an engineer who is already passionate about tackling problems in blockchain scalability, or looking to break into the blockchain engineering space. If you're looking to work in a fast-paced, high-impact team and help shape the direction of our product and company, this position is for you.

We're backed by some of the best investors in the valley and offer competitive pay, an equity grant in the company, and full benefits.

About Caldera

Caldera enables dynamic, scalable blockchain experiences. Currently, dapps that are deployed to general-purpose blockchain compete with thousands of other applications for space on the network - this can lead to congestion and high fees or even network outages.

That's where we come in. We're building software that makes it easy for the most innovative blockchain applications to launch their own ultra-performant blockchains (rollups), enabling applications to own their ecosystem, scale to millions of users, and provide a superior user experience to their users.

We're located in San Francisco, and work in-person from the Financial District
