Evervault builds encryption and data security infrastructure for developers. APIs and primitives for tokenizing, encrypting, and processing sensitive data at scale - currently focused on powering the payments stack for companies like Rippling, Ramp, and Sorare.
What you will do
- Design and build developer-facing APIs and primitives for card data security, tokenization, and network integrations.
- Collaborate directly with enterprise customers to understand their payment stacks and translate complex security needs into production code.
- Own features end-to-end across the full stack, including backend services, SDKs, UI components, and technical documentation.
