A newly created opportunity exists for a Security Engineer to work in a fast-moving, startup-like environment with the freedom to identify risks, set priorities, and implement solutions without constant direction. The ideal candidate will take on a highly hands-on role covering code reviews for vulnerabilities, penetration testing, securing internal tools, and training employees on social engineering risks, working directly with engineering and leadership to build practical security measures.

Responsibilities

• Own and continuously improve security across applications, infrastructure, internal systems, and business operations
• Conduct security-focused code reviews, identify vulnerabilities, and work directly with engineers to implement fixes
• Perform hands-on penetration testing and vulnerability assessments across web applications, APIs, networks, and infrastructure
• Secure internal and external APIs through proper authentication, authorization, access controls, and credential management
• Own identity and access management (IAM), including employee permissions, role-based access controls, least-privilege policies, and regular access audits
• Establish practical security standards for internal tools, third-party services, cloud environments, and production infrastructure
• Lead employee security awareness initiatives, including phishing simulations, social engineering testing, and security training
• Identify risks in everyday employee workflows and implement technical or procedural safeguards to reduce exposure
• Implement and maintain security monitoring, vulnerability scanning, threat detection, and incident response processes
• Build automated security checks into development workflows, including code scanning, dependency auditing, and CI/CD security controls

Skills/Must have

• Strong professional experience in security engineering, application security, infrastructure security, or a similar role
• A self-starter who can manage their own time, establish priorities, and drive projects from identification through implementation
• Comfortable wearing multiple hats and taking responsibility for problems outside a narrowly defined job description
• Hands-on mentality with a willingness to investigate problems, write code, configure systems, and implement fixes personally
• Strong understanding of application security, secure coding practices, and common vulnerabilities such as those outlined by OWASP
• Experience with penetration testing, vulnerability assessments, and security testing tools
• Strong understanding of API security, authentication, authorization, OAuth, access tokens, and credential management
• Experience managing IAM, RBAC, MFA, SSO, and least-privilege access policies
• Strong Linux, networking, Docker, and cloud infrastructure security fundamentals
• Experience securing production applications, databases, internal tools, and cloud environments
• Familiarity with automated security tooling, including SAST, DAST, dependency scanning, and secrets detection
