Security Engineer
Ether.fi, Cayman +2
The role
We're looking for a Security Engineer who is equally at home hardening a CI/CD pipeline, reviewing a change to the authentication system on the backend, and triaging a bug bounty submission before lunch.This is a hands-on, builder-first role - not a governance checkbox. You'll own security operations end-to-end, embedded directly into the engineering team and working closely with infrastructure, protocol and platform.
If you treat threat modeling as a design conversation and not a compliance exercise, you're our kind of person. You should only apply for this role if you are ready to come into the office every day and work in person with our team!
What you will do
In your first 90 days, you've mapped our attack surface, established a daily rhythm on ImmuneFi, and shipped at least a few meaningful PRs across the full stack. Within six months, you've built enough trust in the team that engineers come to you before shipping sensitive PRs, not after.
What you need
- 5+ years of experience in software and security engineering, with meaningful time in a DevSecOps or security operations context
