General Description Duties & Responsibilities

• Design, build, and maintain AI infrastructure across cloud and on-premises environments, including GPU compute clusters.
• Deploy, serve, and optimize self-hosted open-weight LLMs, applying techniques such as quantization, batching, and inference optimization to maximize throughput and minimize latency and cost.
• Build and operate the platform services, pipelines, and tooling that enable AI engineers to develop, test, and deploy agents and models reliably.
• Implement scalable serving infrastructure supporting both batch and streaming inference workloads.
• Establish and maintain MLOps/LLMOps capabilities, including model registries, CI/CD for models and agents, monitoring, observability, and automated deployment.
• Support procurement of GPU servers and AI infrastructure by defining specifications, benchmarking hardware, and validating capacity plans.
• Harden the AI platform in partnership with IT and security teams, implementing appropriate segmentation, access controls, and governance.
• Integrate AI platform infrastructure with enterprise data systems, including Databricks and streaming platforms.
• Automate infrastructure provisioning and configuration using infrastructure-as-code and modern DevOps practices.
• Monitor platform performance, reliability, and utilization; troubleshoot and resolve infrastructure and serving issues.
• Contribute to architecture and design decisions alongside the Principal AI Engineer and Director of AI Engineering.
• Document platform architecture, runbooks, and operational procedures for maintainability.

Qualifications

• 7+ years of experience in infrastructure, platform, DevOps, or machine learning engineering.
• Bachelor's degree in Computer Science, Engineering, Mathematics, or related field of study.
• Hands-on experience deploying and operating GPU infrastructure for AI/ML workloads, on-premises and/or in the cloud.
• Experience serving and optimizing large language models, including familiarity with inference/serving frameworks and optimization techniques (e.g., quantization, batching).
• Strong proficiency with cloud platforms and containerization/orchestration technologies.
• Proficiency in Python and infrastructure-as-code tooling.
• Experience building CI/CD pipelines and implementing MLOps/LLMOps practices.
• Solid understanding of security, networking, and access control in enterprise environments.
• Strong troubleshooting skills and operational discipline for maintaining reliable production systems.
• Excellent interpersonal and communication skills, with strong critical thinking and attention to detail.
• Strong work ethic with the ability to effectively prioritize, meet deadlines, adapt to changing priorities, and succeed in a fast-paced environment.

Preferred Experience

• Experience with LLM serving frameworks such as vLLM, TGI, TensorRT-LLM, or similar.
• Experience with Databricks and streaming data platforms such as Kafka.
• Experience with on-premises AI infrastructure in environments with data residency or security constraints.
• Experience deploying infrastructure in or adjacent to operational technology (OT), industrial, or safety-critical environments.
• Familiarity with agent frameworks and their deployment/runtime requirements.
• Experience with GPU cluster management, scheduling, and utilization optimization.
• Experience utilizing DevOps/MLOps tooling and observability stacks.
• Strong technical writing skills.
