AI Platform Engineer (Hybrid)

What You Will Do: Design, develop, and operate scalable backend services, APIs, and distributed platform capabilities that support enterprise AI applications, models, and agents. Build and integrate AI platform capabilities including model access and routing, AI gateways, agent runtimes, lifecycle management, tool integration, model serving, retrieval services, and related enterprise AI services. Develop secure capabilities for agent and application identity, authentication and authorization, secrets management, tool access, permissions, and integration with enterprise systems. Design and automate deployment across development, test, and production environments using cloud-native technologies, containers, Kubernetes, CI/CD, and infrastructure-as-code. Build observability capabilities including logging, metrics, tracing, monitoring, alerting, execution telemetry, and cost visibility for AI applications and agentic workloads. Develop platform capabilities supporting AI evaluation, model lifecycle management, MLOps, configuration, versioning, and production operations. Design platform services for scalability, availability, resilience, performance, security, and support across commercial cloud, hybrid, on-premises, and restricted environments. Partner with AI Architecture, Applied AI, Application Engineering, Cybersecurity, Data, and product teams to translate solution needs into reusable enterprise platform capabilities and continuously improve the developer experience.

What You Will Learn: How enterprise AI platforms enable Generative AI, machine learning, and agentic applications to operate securely and consistently across a global aerospace and defense company. How models, agents, tools, identity, data, evaluation, and observability come together as reusable enterprise platform capabilities. How AI workloads are designed and operated across commercial cloud, hybrid, on-premises, and restricted computing environments. How production agentic systems introduce new engineering challenges around identity, tool access, runtime governance, state, observability, and operational control. How emerging AI platforms, orchestration technologies, interoperability standards, and cloud services can be evaluated and incorporated into enterprise architectures. How reusable platform capabilities can reduce duplication and accelerate AI solution delivery across multiple RTX business units.
