• Experience with AI evaluation frameworks, prompt testing, or offline/online quality measurement
• Attention to detail, ability to multitask, and strong interpersonal skills.

Preferred:

• Experience in enterprise-scale application development in a SaaS environment.
• Strong observability design across infrastructure and AI workloads (metrics, logging, tracing, AI quality signals)
• Experience with an OOP language
