📋 Description

• Conduct security reviews of systems, architectures, and code — proactively identifying and addressing vulnerabilities. • Serve as a go-to security advisor for engineering teams, helping them make secure design decisions. • Define and implement security standards across cloud infrastructure, applications, and blockchain systems. • Implement and maintain security tooling: vulnerability scanning, endpoint protection, SIEM, logging and monitoring. • Secure CI/CD pipelines and deployment workflows from a security perspective. • Secure internal AI tools and LLM integrations — from API key management and prompt injection prevention to evaluating the security implications of AI adoption across the organization. • Manage and improve secrets management, key management, and access control practices across the organization. • Define and maintain secure coding guidelines and security review processes for engineering teams. • Collaborate with external providers on penetration tests and security audits, ensuring findings are prioritized and remediated. • Participate in incident response: investigation, containment, root cause analysis, and post-incident improvements. • Support compliance and audit readiness by implementing required security controls and maintaining documentation.

🎯 Requirements

• Strong understanding of cloud security (AWS, GCP, or similar), container security, and network security fundamentals. • Hands-on experience implementing and operating security tools (SIEM, vulnerability scanners, endpoint protection, cloud security tooling). • Experience with secrets management, key management, and encryption best practices. • Experience securing AI/LLM tooling, agent-based systems, and modern developer platforms. • Familiarity with securing CI/CD pipelines and developer tooling. • Solid understanding of compliance frameworks (SOC 2, ISO 27001, or similar). • Proficiency with AI-powered tools in day-to-day work, with a drive to find the best balance between productivity and security. • Clear written and verbal communication skills, suited for a remote-first, async environment. • A pragmatic, hands-on mindset — comfortable working across security domains rather than specializing narrowly.

🏖️ Benefits

• Remote-first • Async communication as the default • Purposeful use of video calls • Work across time zones
