Cyber Security Engineer

Experience:

Knowledge, Skills, & Abilities:

• Fluency with AI-assisted development tools like Claude Code and similar agentic coding assistants, including the ability to design, prompt-engineer, and orchestrate agents for security engineering workflows. Production experience where AI was load-bearing in the build.
• Hands-on experience shipping at the agentic tool layer: MCP integrations, custom agent harnesses, or AI tool-use pipelines.
• Strong software engineering fundamentals: version control, code review, testing, CI/CD, and API design, with the ability to write production-quality, maintainable code rather than throwaway scripts.
• Hands-on proficiency with cloud-native engineering: AWS (KMS, IAM, Lambda, EKS, and supporting services), Kubernetes, and Terraform or equivalent IaC tools.
• Technical knowledge of cybersecurity concepts, threat modeling, and secure design principles sufficient to consult on, review, and approve security-critical architectural decisions.
• Working knowledge of PKI concepts and certificate lifecycle management, with the ability to engineer cryptographic lifecycles as code.
• Experience with security telemetry pipelines and log analytics platforms (OpenSearch or similar), including data normalization, enrichment, and the structural fidelity required for downstream automation.
• Working knowledge of cloud security and compliance frameworks (SOC 2, PCI DSS, CIS Benchmarks, AWS Well-Architected), with the ability to translate control requirements into automated, auditable systems.
• Self-directed engineering mindset with a bias toward action, a low tolerance for manual toil, and a drive to eliminate recurring work through automation. A repeated manual process is a bug, not a task.
• Excellent written and verbal communication, including the ability to translate complex security architectures into clear documentation and to operate as a consultative security partner across technical and non-technical teams. Comfort with a fully remote, async-first culture where Slack and thorough documentation are how decisions get made.
• Nice to have: Contributions at the edge of what's possible with security and AI, including open-source projects, agent evaluation work, public writing, talks, or similar.
