About Evervault Limited
Software · 40 employees
Evervault provides modular card payment infrastructure for companies who offer payments as a product, or are building their own in-house multi-PSP orchestration setup. This starts with tooling to collect, store, and send card numbers without raw data touching your infrastructure, minimizing PCI scope. And extends to core payment capabilities that help you increase acceptance rates and reduce transaction fees and chargebacks.
What you will do
- Find and fix vulnerabilities across applications and infrastructure while building automated security checks into the software development lifecycle.
- Collaborate directly with platform engineers to make critical security decisions during product design and system architecture phases.
- Lead security and compliance audits, including evidence collection and resolving findings for PCI DSS and SOC 2 Type II certifications.
Who this is a fit for
- Professional engineering background with deep security expertise and the ability to write production code in Rust, Node.js, or Go.
- Essential experience with PCI DSS compliance and a proven track record of securing complex cardholder data environments in a product-focused company.
- Proactive problem solver who utilizes AI to improve workflows and has experience managing audits through to resolution in a pre-Series C environment.
Why this role is remarkable
- Establish the entire security function from the ground up as the first dedicated hire, defining the practices, tooling, and culture for a critical infrastructure company.
- Work at a high-growth Series B startup backed by premier investors like Sequoia and Kleiner Perkins, serving market leaders in the fintech and payments space.
- Balance deep technical engineering with strategic compliance ownership, staying close to the code while ensuring the highest standards for cardholder data environments.
