About this role
OpenTrain is recruiting a Technical Expert Interviewer to support an AI model training and evaluation engagement.

Strong communication, structured judgment, careful attention to evidence, and reliable time management are important. Familiarity with GPU kernels, security research, ML compilers, or accelerator systems is valuable.
