About the role
About 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'll Do:
Security Operations
- 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)
Bug Bounty & Vulnerability Management
- 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
DevSecOps & Pipeline Hardening
- 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
Infrastructure Security
- 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
Vendor & External Partner Management
- 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
What We're Looking For:
- 5+ years of experience in software and security engineering, with meaningful time in a DevSecOps or security operations context
- Strong software engineering fundamentals - you're a builder who writes code, not just policy
- Hands-on experience hardening CI/CD pipelines (GitHub Actions, CircleCI, or similar) and cloud infrastructure (AWS, GCP, or equivalent)
