**The Senior Machine Learning Engineer – GenAI** is responsible for designing, implementing, and operating large-scale systems and tools for AI model benchmarking, optimization, and validation. Unlike a traditional ML Engineer focused primarily on model training, this role centers on **building the infrastructure, automation, and services that enable systematic evaluation and performance tuning of LLMs at scale** . This position combines **deep understanding of model serving frameworks, GPU optimization, and benchmarking methodologies** with strong software engineering skills to deliver reliable, reproducible, and production-grade evaluation pipelines. The engineer will design and maintain **validation-as-a-service platforms** that allow internal and external stakeholders to assess models across latency, throughput, accuracy, and cost dimensions—integrating seamlessly with Red Hat’s AI ecosystem and industry-standard GenAI tooling. A core aspect of this role is **creating a robust, extensible benchmarking and validation framework** capable of running across diverse inference engines, hardware configurations, and deployment environments, while providing actionable insights for model selection, optimization, and integration. **What you will do:** + **Benchmarking Platform Development** : Design and implement scalable benchmarking pipelines for LLM performance measurement (latency, throughput, accuracy, cost) across multiple serving backends and hardware types. + **Optimization Tooling** : Build utilities and automation to profile, debug, and optimize inference performance (GPU utilization, memory footprint, CUDA kernels, parallelism strategies). + **Validation-as-a-Service** : Develop APIs and self-service platforms for model evaluation, enabling teams to run standardized benchmarks on demand. + **Serving Integration** : Integrate and operate high-performance serving frameworks (vLLM, TGI, LMDeploy, Triton) with cloud-native deployment patterns. + **Dataset & Scenario Management** : Create reproducible workflows for dataset preparation, augmentation, and scenario-based testing to ensure robust evaluation coverage. + **Observability & Diagnostics** : Implement real-time monitoring, logging, and metrics dashboards (Prometheus, Grafana) for benchmark and inference performance. + **Cloud-Native Orchestration** : Deploy and manage benchmarking workloads on Kubernetes (Helm, Argo CD, Argo Workflows) across AWS/GCP GPU clusters. + **Integration with GenAI Tooling** : Leverage Hugging Face Hub, OpenAI SDK, LangChain, LlamaIndex, and internal frameworks for streamlined evaluation workflows. + **Performance Engineering** : Identify bottlenecks, apply targeted optimizations, and document best practices for inference scalability. + **Ecosystem Leadership** : Track emerging frameworks, benchmarks, and optimization techniques to continuously improve the evaluation platform. **What you ill bring:** + **Advanced Python** for backend development, data processing, and ML/GenAI pipelines. + **Kubernetes (Deployments, Services, Ingress) and Helm** for large-scale distributed training and inference workloads. + **LLM training, fine-tuning, and optimization** (PyTorch, DeepSpeed, HF Transformers, LoRA/PEFT). + **GPU optimization expertise** : CUDA, mixed precision, tensor/sequence parallelism, memory management, and throughput tuning. + **High-performance model serving** with vLLM, TGI, LMDeploy, Triton, and API-based serving (OpenAI, Mistral, Anthropic). + **Benchmarking and evaluation pipelines** : dataset preparation, accuracy/latency/throughput measurement, and cost–performance tradeoffs. + **Multi-model, multi-engine comparative testing** for optimal deployment decisions. + **Hugging Face Hub** for model/dataset management, including private hosting and pipeline integration. + **GenAI development tools** : OpenAI SDK, LangChain, LlamaIndex, Cursor, Copilot. + **Argo CD & Argo Workflows** for reproducible, automated ML pipelines. + **CI/CD** (GitHub Actions, Jenkins) for ML lifecycle automation. + **Cloud (AWS/GCP)** for provisioning, running, and optimizing GPU workloads (A100, H100, etc.). + **Monitoring & observability** (Prometheus, Grafana) and **databases** (PostgreSQL, SQLAlchemy). **Nice to have:** + **Distributed training** across multi-node, multi-GPU clusters. + **Advanced model evaluation** : bias/fairness, robustness, and domain-specific benchmarks. + **Experience with OpenShift/RHOAI** for enterprise AI deployments. + **Benchmarking frameworks** : GuideLLM, HELM, Eval Harness. + **Security scanning** for artifacts/containers (Trivy, Grype). + **Tradeoff-analysis tooling** for model selection and deployment \#AIHiring \#LI-YB1 **About Red Hat** Red Hat (https://www.redhat.com/) is the world’s leading provider of enterprise open source (https://www.redhat.com/en/about/open-source) software solutions, using a community-powered approach to deliver high-performing Linux, cloud, container, and Kubernetes technologies.
