[Hiring] Senior DevSecOps / Platform Security Engineer @DEFCON AI

Role Description

We’re hiring a senior, hands-on DevSecOps/Platform Security Engineer to build and operate production security controls across our AWS and Kubernetes platform. You’ll design and implement guardrails that make secure delivery the default—covering CI/CD security automation, software supply chain controls, and Kubernetes policy enforcement—while partnering closely with Platform/SRE and Security/GRC.

What You'll Own:

• CI/CD security automation and developer-facing security workflows (SAST/SCA, secrets scanning, IaC scanning, container scanning).
• Software supply chain controls (SBOM, artifact/image signing and verification, provenance and promotion workflows).
• Kubernetes policy enforcement and admission controls (policy-as-code) that encode platform security guardrails.
• Co-own AWS security guardrails with Platform/SRE (IAM patterns, logging and detection, network and encryption baselines).
• Partner with Security/GRC on control interpretation and evidence needs; implements controls in engineering systems and pipelines.

What You’ll Do:

• Design, build, and maintain CI/CD security controls that scale across repositories and teams (reusable pipeline components, templates, and standards).
• Implement Kubernetes security architecture and guardrails (RBAC hardening, workload security baselines, admission policies, network policies, and safe multi-tenant patterns as applicable).
• Improve container security end-to-end: base-image strategy, vulnerability scanning, registry controls, image signing, and promotion workflows.
• Operationalize vulnerability management with risk-based prioritization, measurable remediation SLAs, and dashboards/metrics (MTTR, exposure trends, top recurring root causes).
• Drive developer enablement: clear documentation, lightweight design reviews/threat modeling for high-impact changes, office hours, and high-signal guidance embedded in tooling.

Real Production Responsibility:

• This role builds and runs production security systems.
• You'll ship code and infrastructure, not just recommendations.
• You'll own reliability and outcomes for the controls you build.
• You'll respond to incidents and on-call rotation related to platform security controls and pipeline reliability (scope aligned with Platform/SRE).

Regulated Environment Support:

This role supports delivery into regulated environments and works closely with Security/GRC to implement engineering-owned controls and produce audit-ready evidence. You’ll help translate requirements (for example, NIST SP 800-171 and CMMC expectations) into practical, automated guardrails within CI/CD, AWS, and Kubernetes.

Qualifications

• 5+ years of experience in DevOps/SRE/Platform Engineering and/or Security Engineering with a strong automation and delivery focus.
• Hands-on experience securing AWS environments: IAM (least privilege), network controls, encryption (KMS), and centralized logging/detection.
• Strong Kubernetes security experience (EKS or equivalent): RBAC, workload hardening, and policy enforcement via admission control.
• Experience integrating security into CI/CD pipelines and developer workflows (SAST, SCA, secrets scanning, container scanning, IaC scanning).
• Infrastructure as Code proficiency (Terraform, CloudFormation, CDK, or Pulumi) and ability to embed guardrails into IaC workflows.
• Proficiency scripting/coding (e.g., Python, Go, Bash) to build integrations, automations, and internal tooling.
• Able to communicate risk and tradeoffs clearly and pragmatically to engineers; improves signal-to-noise rather than adding friction.

Requirements

• Experience with Kubernetes policy-as-code tooling (OPA/Gatekeeper, Kyverno) and secure workload identity patterns (OIDC/IRSA).
• Experience with software supply chain security: SBOM generation and management, signing/verification (e.g., cosign), and provenance concepts.
• Experience building ‘golden paths’ or internal developer platforms that improve both delivery velocity and security outcomes.
• Familiarity with regulated delivery expectations (NIST SP 800-171/CMMC) and evidence-driven control implementation.

Benefits

• A fully remote, results-based environment.
• Competitive salary, bonus, and equity package.
• 100% employer paid, comprehensive health insurance including medical, dental, and vision for you and your family.
• Unlimited PTO, with your manager’s approval.
• Flexible work environment where you manage your work day.
• 14 weeks of fully-paid parental leave.
• Salary range: $175,000-$215,000. This represents the typical salary range for this position based on experience, skills, and other factors.
