## 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 offboarding (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 to SLAs, 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 - **5–8+ 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) - Proficiency with endpoint security tooling (CrowdStrike or equivalent EDR) - Comfort owning identity and access management processes, including onboarding/offboarding workflows - Strong communication skills — you can write a clear triage report, give direct feedback to a developer and explain risk to a non-technical stakeholder ## Nice to Have - 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 ## What Success Looks Like 1. 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. 2. Within six months, you've built enough trust in the team that engineers come to you before shipping sensitive PRs, not after. *When applying, mention the word CANDYSHOP to show you read the job post completely.*
