Salary:

150000.00 - 300000.00 USD / Year

Reducto

Expiration Date

Until further notice

Requirements

Philosophy: You are your own worst critic. You have a high bar for quality and don't rest until the job is done right—no settling for 90%. We want someone who ships fast, with high agency, and who doesn't just voice problems but actively jumps in to fix them
Experience: You have 3+ years of hands-on security engineering experience, ideally in high-growth startups or cloud-native environments. You've been through at least one SOC2 or similar compliance audit
Technical Depth: You're comfortable reading and auditing code (Python strongly preferred), understanding infrastructure architecture, and implementing security controls across the stack—from application layer to cloud infrastructure
Tools: Build your own tools as needed—whether it's a quick script to audit secrets across repos or an internal dashboard to track security metrics
Approach: A practical, risk-based approach to security. You understand when to say no and when to help engineering ship securely. You can balance security rigor with business velocity and aren't dogmatic about perfect security at the expense of progress

Job Responsibility

Owning and managing SOC2, HIPAA, and other compliance certifications end-to-end, including evidence collection, control implementation, and audit coordination
Implementing proactive security monitoring and alerting systems to detect and respond to threats in real-time across our cloud and on-prem deployments
Building and maintaining security CI/CD tooling to catch vulnerabilities before they reach production—static analysis, dependency scanning, secrets detection, and more
Managing our relationship with platforms like Vanta to streamline compliance workflows and maintain continuous monitoring
Responding to customer security questionnaires and conducting security reviews for enterprise deals
Establishing and managing our bug bounty program, triaging vulnerabilities, and coordinating remediation with engineering teams
Working directly with the founders and customers to shape our security strategy and build trust with enterprise buyers

Unlimited PTO
Lunch: Receive a free lunch to eat with your teammates daily at the office
