Security Engineer

About Evervault

Evervault offers modular payments infrastructure for companies building their own payments stack. We keep raw card data off your systems, cut PCI compliance work, improve acceptance, mitigate fraud and chargebacks and decrease your cost of payments, so you keep full control. Trusted by Ramp, Rippling, Modern Treasury and Overwolf; Series B, led by Ribbit Capital.

Role Overview

We're hiring our first dedicated Security Engineer. You'll join our platform group and own application security from day one, with scope to take on security across Evervault over time. Expect roughly half your first year on hands-on security engineering and half on audits, questionnaires and customer security reviews. Both are core to the job.

What You'll Be Doing

• Finding and fixing vulnerabilities in our applications and infrastructure

• Building security checks and tooling into how we develop and ship software

• Working with engineers on security decisions in product and system design

• Owning security and compliance audits, including evidence collection and resolving findings

• Handling customer security reviews and questionnaires, and explaining our controls clearly

• Setting how the security function works, through the code you ship and the practices you help the team adopt

Requirements

• Strong engineering skills: comfortable writing production code, investigating unfamiliar systems and taking a fix through to completion

• Deep, practical security expertise across application and infrastructure security

• Hands-on experience with PCI DSS

• Experience taking audits through to resolution

• You use AI daily and actively look for ways it can improve your work

Nice to Have

• Experience in card payments, particularly running or securing a cardholder data environment

• Experience as a first or sole security engineer

• A product company background before Series C

• Rust, Node.js, AWS or Terraform (we care more about engineering ability than our exact stack)

This Might Not Be for You If…

• You want pure offensive or research work: around half the role is audits, questionnaires and customer reviews

• You want to manage people soon: this is an individual contributor role with no immediate management remit

• You need a tightly defined brief: you'll be shaping the security function as you go

• You want to work fully remotely: we're in our Shoreditch office Tuesday to Thursday

Compensation, Benefits & Why Join

• Competitive London Salary

• Stock options with an extended exercise window

• Full, top-tier health insurance

• Generous vacation and flexible working hours

• Define the security function at a fast-growing payments infrastructure company, working closely with the engineers who build it
