  • Design and build scalable AI/ML and analytics platforms.

  • Develop infrastructure and tooling to support ML experimentation, training, deployment, and monitoring.

  • Enable self-service capabilities for ML Engineers, Data Scientists, and Analysts.

  • Architect and optimize distributed computing solutions for large-scale data processing.

  • Collaborate cross-functionally with research, engineering, and analytics teams.

  • Ensure performance, reliability, and scalability of ML systems in production environments.


Required Qualifications
  • Bachelor’s or Master’s degree in Computer Science, Engineering, Data Science, Mathematics, Statistics, Operations Research, or a related quantitative field.

  • 5+ years of experience in software engineering, platform engineering, or related roles.

  • Proven experience building AI/ML or analytics platforms.

  • Strong experience with at least one strongly typed programming language (e.g., C/C++, Java, Go, Rust).

  • Experience working with distributed systems and large-scale data processing frameworks (e.g., Ray, Dask, Spark).

  • Experience supporting ML or analytics workloads in production environments.


Preferred Qualifications
