Security Engineer

We're hiring for a Security Engineer to own the day-to-day defensive and offensive security posture of Coinflow. You'll build the SecOps backbone, hunt for weaknesses in our own stack before anyone else does, and partner with engineering to keep our SDLC fast and secure. This role reports to the CISO and has a direct line into every part of the engineering org.

You'll be hands-on with modern AI-native security tooling — we use Claude Security and Claude Code as force multipliers for internal pentesting, code review, and remediation. If you're excited about being one of the first security engineers building this way, you'll fit in well here.

• SIEM & SecOps Dashboard: Stand up and operate our SIEM. Build out the SecOps dashboard that gives engineering, compliance, and leadership a real-time picture of our security posture — alerts, anomalies, auth events, infrastructure changes, and audit-ready evidence in one place.
• Internal Penetration Testing: Run continuous internal pentests against Coinflow services, APIs, infrastructure, and embedded SDKs. Use Claude Security and Claude Code to scale your coverage — automate reconnaissance, fuzzing, code review, and exploit development. Document findings, drive remediation, and measure mean-time-to-fix.
