  • Benchmark and profile models across diverse workloads and hardware environments
• Model Integration & Deployment
  • Integrate ML/LLM models into APIs, microservices, and applications
  • Build and maintain model-serving infrastructure (e.g., vLLM, ONNX, custom runtimes)
  • Collaborate with platform and infrastructure teams for scalable deployment
• Data & Pipeline Engineering
  • Design data pipelines for ingestion, preprocessing, feature engineering, and validation
  • Improve data quality and model reliability through systematic evaluation
• Cross-functional Collaboration
  • Partner with product, platform, and hardware teams to deliver end-to-end ML solutions
  • Participate in design reviews and contribute to system architecture decisions

Minimum Qualifications:

OR

Master's degree in Computer Science, Engineering, Information Systems, or related field and 1+ year of Hardware Engineering, Software Engineering, Systems Engineering, or related work experience.

OR

PhD in Computer Science, Engineering, Information Systems, or related field.

Preferred Qualifications

Strong programming skills in Python and at least one systems language (C++/Rust/Go)
