Phantom is built by a team of experienced product and engineering leaders working to make crypto-powered finance safer and easier to use. Our platform supports products used by tens of millions of people, making infrastructure security both technically challenging and directly consequential.

This role offers the opportunity to:

Secure AWS and Kubernetes systems supporting products used by millions of people.

Work on high-impact problems spanning cloud identity, production access, workload isolation, software supply chains, and mission-critical infrastructure.

Build controls directly in the platform rather than operating as an advisory or review-only security function.

Influence architecture early and own improvements through implementation and production verification.

Help shape an AI-native security team with a strong engineering and automation culture.
