ML Infra Engineer (m/f/d)

Role Overview

This role focuses on designing and building the infrastructure that enables scalable machine learning development, from training-ready datasets through to validated models deployed in production environments.

The position involves establishing core systems and architectural foundations that will support long-term scalability and performance. Key areas include training infrastructure, distributed learning frameworks, experiment management, model lifecycle management, and reliable pathways from model development to production deployment.

Key Responsibilities

• Training infrastructure

Design, deploy, and operate GPU-based training environments across cloud platforms such as AWS and GCP. This includes node provisioning, workload scheduling (e.g., Kubernetes, Slurm), multi-node networking, GPU monitoring, and cost/utilization optimization.

• Distributed training systems

Own and optimize distributed training frameworks such as PyTorch DDP and FSDP. Implement and tune strategies including mixed precision, gradient checkpointing, activation offloading, and parallelism approaches to ensure efficient large-scale training.

• Training data I/O performance

Develop high-throughput data loading and storage access patterns to support multi-GPU and multi-node training. Implement techniques such as data sharding, prefetching, local NVMe caching, and resumable data pipelines. Contribute to dataset format design with a focus on efficient read performance.

• Experiment tracking and model management

Implement and maintain experiment tracking and model registry systems using platforms such as MLflow or Weights & Biases. Ensure reproducibility, traceability, and comparison of experiments through proper artifact and checkpoint management.

• ML CI/CD pipelines

Build automated pipelines for training, evaluation, and deployment readiness. Establish validation gates, regression testing, and controlled promotion of models across different lifecycle stages.

• Model packaging and deployment pipelines

Develop reliable CI/CD workflows for model conversion, benchmarking, and packaging using tools such as ONNX, TensorRT, SNPE, or TIDL. Ensure all artifacts are properly versioned and tracked with full lineage.

• Production monitoring and feedback loops

Design and implement systems that capture model performance in production environments. Enable continuous feedback loops by feeding operational data back into retraining and evaluation pipelines.

Required Experience

• 5+ years of experience building and operating ML infrastructure for production-grade deep learning systems, ideally including computer vision or perception-based workloads
• Strong proficiency in Python, with working knowledge of C++ for inference runtimes and deployment tooling
• Deep hands-on experience with distributed training at scale (DDP, FSDP), with the ability to troubleshoot performance, stability, and memory issues
• Experience operating GPU clusters on AWS and/or GCP, including scheduling frameworks (e.g., Kubernetes, Slurm) and understanding of networking and storage trade-offs
• Proven experience with experiment tracking, model registries, and ML CI/CD workflows in production environments
• Track record of building end-to-end infrastructure supporting the full model lifecycle, from training through deployment

Preferred Qualifications

• Background in autonomous systems, perception, or complex real-world ML applications
• Familiarity with inference optimization toolchains (TensorRT, ONNX, SNPE, TIDL) and their integration into deployment pipelines
• Understanding of multimodal or sensor-based datasets and formats (e.g., MCAP, rosbag2)
• Experience working with real-time inference constraints and deployment environments requiring optimized performance
