Senior ML / Evaluation Engineer

Company: EPAM Systems

Join the Enterprise Agent Development Platform project at EPAM. We are building a cloud-native platform that enables engineering teams to develop, deploy, and operate AI agents in production.
The platform combines modern agent frameworks, AWS infrastructure, CI/CD, observability, and governance to make AI development faster and more reliable.
As a Python AI Evaluation Engineer, you will own a key part of this platform: building the capabilities that measure and validate the quality of AI solutions. You will design evaluation approaches, develop custom evaluators, and integrate quality checks into the software delivery lifecycle.
This role is a strong fit for an engineer who enjoys solving new GenAI challenges and turning them into practical, automated engineering solutions.
Unlock the potential of remote work in Kazakhstan, giving you the flexibility to work from home or access our offices in Astana, Almaty or Karaganda.
