Security Engineer

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!

Own day-to-day security operations: monitoring, alerting, triage, and response

Manage and monitor endpoint security via an EDR system — tune detections, investigate alerts, and drive incidents to resolution

Lead identity lifecycle management, including employee onboarding and off boarding (access provisioning, key rotation, deprovisioning)

Be the primary owner of our ImmuneFi program — triaging, reproducing, and responding to incoming submissions daily

Prioritize and track vulnerabilities through to remediation in close collaboration with protocol and engineering teams

Develop internal tooling and processes to make the bounty workflow faster and more consistent

Audit and harden CI/CD pipelines — secrets management, supply chain integrity, SAST/DAST integration, build provenance

Own dependency security: identify and remediate vulnerable packages across repositories (yes, including the npm dependency hell)

Establish and enforce security standards across the SDLC

Partner with the infrastructure team to review and harden cloud environments (access controls, network segmentation, least privilege, logging)

Contribute to threat modeling for new systems and architectural changes

Drive implementation of security tooling across the stack

Own relationships with external security vendors and service providers — holding them accountable toSLAs, managing scope, and ensuring findings are actioned

Evaluate and onboard new security tooling as the team and threat landscape evolve

You were a traditional software engineer before specializing in security

Prior experience at a DeFi protocol, crypto exchange, or blockchain infrastructure company

CTF/security competition background

Contributions to open-source security tooling

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.
