Overview We are seeking a highly skilled and proactive IT Infrastructure Engineer with deep expertise in cloud and Dev Ops practices and a strong working knowledge of AI tooling and infrastructure. This role sits at the intersection of modern cloud infrastructure engineering and the rapidly evolving AI enablement space. You will play a hands‑on IC role in deploying and maintaining the AI tools, agents, hosting environments, and cloud infrastructure that support User Testing’s broader AI initiatives, along with other infrastructure and IT responsibilities. Target ratio is an 80/20 split of AI “building” vs traditional cloud infrastructure/IT work.

Key Responsibilities
Set up, configure, and maintain MCP (Model Context Protocol) servers that connect AI systems to internal tools and data sources, including scoping access, managing credentials, and troubleshooting integrations. Design, provision,



and support hosting environments for internally built AI applications ranging from lightweight Paa S deployments to full cloud infrastructure on AWS/GCP (VPCs, compute, containers, load balancing) depending on the app’s complexity and scale requirements. Familiarity with AI features within existing Saa S platforms (e.g., Atlassian Rovo, Slack AI, Okta AI, Chat GPT, Google Gemini). Provision and support AI agent / application infrastructure: service accounts, API key management, permissions scoping, rate limit monitoring, and access auditing for agents operating across internal systems and cloud environments. Build and maintain CI/CD pipelines and infrastructure-as-code (e.g., Terraform, Cloud Formation) to support repeatable, secure deployment of AI-hosted applications and supporting services. Maintain documentation for all AI integrations and hosted environments, including architecture diagrams, access maps, runbooks, cost/usage tracking, and troubleshooting guides. Stay current on the AI tooling and cloud ecosystem and proactively identify tools, platforms, or integrations that could benefit the IT team or the broader organization. Support the administration of User Testing’s IT cloud infrastructure (AWS and/or GCP) and Dev Ops toolset across the organization as it relates to IT’s AI Infrastructure. Become a subject matter expert for AI-hosted platforms, cloud integrations, and supporting infrastructure. Monitor uptime,



performance, and cost of hosted AI applications; implement alerting and observability (e.g., Datadog, Cloud Watch, GCO) to catch issues before they affect users. Identify, prioritize, and address technical debt across cloud infrastructure, deployment pipelines, and integrations. Partner with other IT System Admins and Engineering/ Security teams to improve reliability, automation, documentation, and supportability of hosted environments. Act as an escalation point for complex infrastructure and hosting issues for the IT support team. Collaborate with cross-functional teams (Security, Engineering, People Ops, etc.) to improve cloud governance, security posture, and AI tool/app hosting adoption. Stakeholder management, this role will act (at times) as a project lead in some capacity. The ability to interact, demo and collaborate with non technical counterparts is critical. Document procedures, system changes, and troubleshooting workflows.

Job Description
The IT team at User Testing manages company-wide systems and serves as an integration, automation, and support layer for the company’s many technology initiatives. This role extends that mission into the AI space, with a particular focus on cloud infrastructure. An idóneo candidate is someone who can transition between managing our cloud infrastructure and configuring AI tools and systems like custom MCPs, complex agent-based solutions, and hosting environments for internally built AI applications. The person in this role won’t operate like a traditional software developer (In house IT focus vs public app focus), but must be comfortable working in technical, cloud-native environments with all that entails from an infrastructure and connectivity standpoint
