Senior Infrastructure Security Engineer

HELP PROTECT THE SYSTEMS THAT POWER INNOVATION AND MANUFACTURING EXCELLENCE.

POLYWOOD is looking for a Senior Infrastructure Security Engineer who thrives in high-ownership environments and is passionate about securing modern infrastructure. This role blends security strategy hands-on engineering and AI safeguarding to protect critical systems while enabling operational continuity in a manufacturing environment.

If you take full accountability for outcomes think proactively about emerging threats and enjoy building security programs that make a measurable impact this opportunity is for you.

What Youll Do:

• Develop and own POLYWOODs infrastructure security strategy and long-term roadmap - not just maintain what exists but build whats needed.
• Design and implement secure cloud-native architectures across AWS and Azure including multi-account IAM network segmentation endpoint protection and threat detection.
• Lead AI safeguarding initiatives - securing LLM endpoints RAG pipelines and agentic systems against prompt injection data poisoning adversarial inputs and inference-layer threats.
• Build and manage enterprise security controls across identity endpoint network and cloud security posture.
• Proactively hunt for threats before they trigger alerts. Build detection capabilities that find risks early.
• Own and lead incident response end-to-end: detection containment root cause analysis and post-incident hardening.
• Partner cross-functionally with IT engineering and operations to embed security into processes architecture and culture.
• Develop and enforce security policies standards and compliance frameworks.
• Continuously evaluate and improve security posture controls and operational resilience.
• Provide clear security guidance and reporting to leadership translating complex risk into decisions the business can act on.

-------

What You Bring:

• 710 years of experience in security engineering with demonstrated ownership of security programs (vs participation in programs someone else built).
• Production-grade experience securing AI/ML systems: LLM endpoints RAG pipelines agentic workflows or model integrity controls. Research and general awareness are not substitutes for having done the work in a live environment.
• Cloud security architecture depth across AWS and/or Azure: multi-account IAM design Service Control Policies GuardDuty Security Hub CloudTrail and cloud-native detection. Console familiarity is not architecture.
• Technical fundamentals you can discuss cold in conversation without notes: TLS handshake mechanics SPF/DKIM/DMARC mechanisms CORS exploitation SQL injection mechanics and forensics-first incident response.
• Incident response leadership experience end-to-end: detection through resolution through post-mortem wit documented improvements that prevented recurrence.

Preferred Skills:

• The ability to operate independently from day one. This role has no ramp-up runway for fundamentals. You will assess the environment identify gaps and start building - without waiting to be directed.
• Strong communication skills: you will brief senior leadership push back on engineering decisions and explain security risk to people who do not speak security.
• Experience in manufacturing industrial or operational technology (OT) environments - specifically understanding that availability beats confidentiality on a plant floor knowing why active scanning can disrupt
• OT equipment and familiarity with the Purdue model or ISA/IEC 62443 for ICS segmentation.
• Familiarity with risk intelligence platforms and advanced threat modeling techniques applied to real environments.
• CISSP CISM GPEN GICSP or equivalent certifications.

Why Youll Love Working With Us:

• High Impact Role: Directly shape the security posture of a growing technology-driven manufacturer.
• Ownership Culture: Work in an environment that values Extreme Ownership and accountability.
• Strategic Influence: Lead AI safeguarding and infrastructure security strategy at the enterprise level.
• Continuous Growth: Stay ahead of emerging threats and technologies while driving meaningful improvements.
• Purpose Driven Work: Protect the systems that power sustainable manufacturing and innovation.
