Job Description

Note: We are recruiting on behalf of our valued client. This opportunity is for a position with their organization, not with People Culture Talent. We're excited to help connect talented professionals with this exceptional team!

The Role

We’re seeking an experienced ML Infrastructure Software Engineer to build and improve infrastructure for machine learning workloads. You’ll partner with researchers and engineers to support experimentation, training, evaluation, and production deployment, with a focus on reliability and performance.

What You’ll Own

Design and build infrastructure for model training and production serving.
Develop reliable pipelines and shared tools that help teams run and manage machine learning workloads.
Improve compute utilization, workload scheduling, and performance across distributed systems.
Use profiling and monitoring to identify bottlenecks, troubleshoot failures, and guide improvements.
Automate testing and measurement to help teams assess changes consistently.
Lead architectural decisions, explain trade-offs, and carry projects from initial design through deployment and ongoing operation.
Collaborate with researchers and engineering teams to turn evolving requirements into maintainable systems.

What You’ll Bring

Substantial software engineering experience with technical ownership at Senior Engineer level or equivalent.
A track record of personally designing, building, and operating core machine learning infrastructure.
Hands-on experience with PyTorch, model serving engines, and distributed training frameworks
Strong experience with distributed systems and large-scale compute environments, including GPU-based workloads.
Solid background in reinforcement learning (RL) post-training infrastructure, RLHF, or automated model evaluation pipelines
Practical experience with modern machine learning frameworks and their supporting infrastructure.
Strong systems design, debugging, and performance optimization skills.
Clear, concise communication and the ability to explain your contributions, architectural choices, and technical trade-offs.
Experience owning systems over time, including maintenance, reliability, and improvements as requirements evolve.

Preferred experience

Experience supporting both training infrastructure and production model deployment.
Experience with large language model workloads is a plus, but not required. Infrastructure experience with other types of machine learning models is equally relevant.

Compensation Range: $150K - $350K
