Sr. AI Platform Engineer

Realtor.com is looking for an AI Platform Engineer to build, operate, and continuously improve the internal AI tooling foundation that powers safe, scalable AI adoption across the company. This role will focus on access controls, platform maintenance, operational support, and governance for key AI tools including Portkey, Claude, Gemini, Windsurf, and Glean.

You will partner closely with AI Solutions Engineers, Security, IT, Legal, and business teams to ensure our approved AI surfaces are reliable, well-governed, cost-aware, and easy to use. This role is intended to handle infrastructure, gateway operations, and production-grade reliability, freeing solution builders to focus on workflow design and delivery.

If you thrive on making complex platforms secure, maintainable, and operationally excellent—and enjoy helping users successfully adopt new tooling—this role is for you.

Top reasons to apply

• Help shape the enterprise AI productivity platform and the paved-path tooling stack at Realtor.com, including Glean, Portkey, Claude, Gemini, Windsurf, and related platforms.
• Build the operational backbone for AI by improving governance, access, support, observability, and reliability across our approved tools.
• Make a company-wide impact by enabling safe AI adoption for employees while reducing fragmentation, vendor sprawl, and uncontrolled spend.

What you'll do

• Own day-to-day platform operations for Portkey, Claude, Gemini, Windsurf, and Glean, including provisioning, deprovisioning, access requests, license hygiene, and support workflows.
• Design and enforce access controls such as SSO, role-based access, least privilege, connector approvals, and periodic access reviews across AI tools and integrations.
• Operate and mature the LLM gateway layer with Portkey or similar tooling to centralize model access, routing, observability, guardrails, spend limits, rate limiting, and PII controls.
• Support approved AI platforms as part of the company’s paved path, helping define where each tool fits and how teams should use them responsibly.
• Monitor platform health, usage trends, reliability, incidents, and cost signals; turn findings into operational improvements, support documentation, and decision-ready reporting.
• Lead maintenance activities such as configuration updates, version management, vendor coordination, renewal support, and change-management readiness for AI platforms and integrations.
• Create and maintain runbooks, support guides, operating procedures, and handoff documentation so teams can use AI tooling confidently and sustainably.
• Partner with Security, Legal, and governance stakeholders to align tooling with approved policies, acceptable use rules, data handling requirements, and News Corp expectations.
• Help standardize and rationalize the AI tool stack, including migrations away from legacy or duplicative tools and toward governed enterprise-supported platforms.
• Serve as an escalation point for user issues and operational blockers, working across internal teams and vendors to resolve problems quickly and improve the user experience over time.

What you'll bring

• 5+ years experience administering or supporting enterprise AI tools, developer tooling, or SaaS platforms with a strong focus on access management, operational support, and maintenance.
• Hands-on familiarity with tools such as Glean, Gemini, Windsurf, Claude, and Portkey, or closely related AI platforms.
• Strong understanding of SSO, RBAC, least privilege, identity lifecycle management, and secure connector governance.
• Experience with observability, monitoring, incident alerting, and service reliability practices that support SLAs and platform health.
• Comfort working with APIs, cloud platforms, and technical integrations across enterprise systems.
• Familiarity with change management, documentation, configuration management, and support processes for production systems.
• Strong judgment around AI governance, data handling, and safe rollout practices in enterprise environments.
• A service-oriented mindset with the ability to translate technical constraints into practical guidance for both technical and non-technical users.
• Bachelor’s degree in Computer Science, Engineering, Information Systems, or a related field—or equivalent practical experience.

How success is measured in year 1

• Core AI tools have clear, scalable access and support processes with strong license hygiene, documented ownership, and timely provisioning and deprovisioning.
• Portkey or the approved gateway layer is operating as a trusted foundation for centralized model access, guardrails, and observability.
• Claude, Gemini, Windsurf, and Glean are supported through a more governed, maintainable, and cost-aware operating model.
• AI Solutions Engineers and business teams can rely on stable paved-path platforms, runbooks, and support channels rather than ad hoc platform ownership.
• Leadership has better visibility into tool adoption, usage, costs, risks, and reliability through recurring reporting and operational metrics.
