The Infrastructure Security Engineer designs, configures, and evolves Security Engineering services and platforms, building the technical capabilities and automation that enable the organization to efficiently implement the controls, governance, and protection needed to keep its assets secure. This is a hands‑on, technically deep role for someone deeply curious about how systems break, understanding vulnerabilities from how they arise to how they’re exploited and remediated, reaching for the right tool across a broad security toolset, and comfortable with red‑team engagements and pentesting to validate weaknesses and demonstrate real‑world risk. This role requires at least a working knowledge of one programming language and automation fundamentals, a strong foundation in network security, networking fundamentals, and core infrastructure including PKI and certificate management, web application mechanics, and client‑server relationships, alongside hands‑on experience maintaining Palo Alto firewalls.

• Curate and evolve our security services and product catalog, ensuring each service is clearly defined, has service levels set and is marketed to key stakeholders, informed by findings surfaced during pentesting and red team engagements.
• Participate in business cases and storyboards that justify spend and technical decisions, including investments in Security Engineering applications built in house, working closely with the operations team to stay aligned on direction.
• Assist with the development of in house security tooling and automation that operationalizes internal and external pentesting workflows, turning offensive findings into repeatable, validated controls.
• Take on the technical development of recovery and business continuity plans, ensuring the security infrastructure survives system shocks and internal, or external events and validating resilience through offensive testing.
• Collaborate with Information Security & Information Technology leaders to define the year to year Network Security program roadmap, inclusive of our security platforms and in house engineered applications.
• Drive hyper automation into all security products and services, so minimal human engagement is needed to deliver desired outcomes, building the tooling in house where it gives us an edge.
• Provide exceptional experiences for our guests, partners, and team members, including by adhering to our appearance and presentation guidelines while on‑site.
