Job Title: Senior Infrastructure Security Engineer Company Name: POLYWOOD Job Url: https://recruiting.paylocity.com/Recruiting/Jobs/Details/3917993?jr_id=69c1975e2c312363dcd4a37c Job Description: Senior Infrastructure Security Engineer Fully Remote • Fort Wayne Description 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 You’ll Do: Develop and own POLYWOOD’s infrastructure security strategy and long-term roadmap - not just maintain what exists, but build what’s 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: 7–10+ 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 You’ll 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.  ---------------------------------------------------------------------   About Us  At POLYWOOD®, we design and build outdoor furniture that brings people together and stands the test of time.  We do this using sustainable materials like our genuine POLYWOOD® lumber made from recycled plastics.  But the strength of our products starts with the strength of our people.  Check out this video - Genuine Polywood The Sr. Infrastructure SecOps Engineer plays a critical role in protecting the systems that support our manufacturing operations, supply chain, and innovation initiatives.
