About the Role

Realtor.com is seeking a Senior AI Platform Engineer to architect, build, and enhance the internal AI tooling foundation, ensuring safe and scalable AI adoption across the company. This role combines software engineering principles with enterprise platform management, focusing on building frameworks, protocols, and developer tools for secure autonomous agent interaction while managing the operational health, access, and maintenance of key AI tools.

Responsibilities

Design and implement the core software platform, APIs, and SDKs for agentic use cases, focusing on orchestration, memory layers, and state management.
Manage the day-to-day operational lifecycles for Portkey, Claude, Gemini, Devin, and Glean, including provisioning, deprovisioning, access requests, license hygiene, and technical support.
Implement and extend industry protocols and standards such as Model Context Protocol (MCP), Agent-to-Agent (A2A) communication, and Agentic Resource Definition (ARD).
Mature the LLM gateway layer to centralize model access, routing, semantic caching, deterministic guardrails, spend limits, rate limiting, and PII controls.
Implement identity lifecycle management, SSO, role-based access control (RBAC), least privilege, and connector approvals as code (Policy-as-Code).
Lead platform maintenance activities, including configuration updates, version management, vendor coordination, and renewal support.
Create and maintain robust runbooks, support guides, and handoff documentation.
Serve as an operational escalation point, partnering with Security, IT, Legal, and business teams to resolve user issues and operational blockers.
Build and govern a greenfield AI platform, defining standards and guardrails for AI system development, governance, deployment, monitoring, rollback, and shutdown.
Design, secure, and scale AWS infrastructure for AI systems and platforms, with experience in Bedrock, IAM, network security, private connectivity, egress controls, and policy-based access.
Facilitate collaborative design reviews to define and socialize AI architectural standards across the organization.
Act as a central technical stakeholder, partnering with engineering departments to validate requirements, unify solution architectures, and ensure platform standards align with engineering needs.

Requirements

5+ years of Software, Platform, or Systems Administration experience with a focus on access management, support, and maintenance of enterprise AI tools, developer tooling, or SaaS platforms.
Hands-on familiarity with configuring, deploying, or building systems leveraging agentic architectures, tool-calling, and platforms like Glean, Gemini, Devin, Claude, and Portkey.
Strong understanding of SSO, RBAC, least privilege, identity lifecycle management, secure data handling, and secure connector governance in an enterprise environment.
Proficiency in modern backend languages (Python, Go, TypeScript) and technical integrations.
Experience with observability, monitoring, incident alerting, and service reliability practices.
A strong engineering philosophy rooted in documentation, change management, configuration management, and support processes for production-grade systems.
Ability to translate technical constraints into practical guidance for both technical and non-technical users.
