  • Hands-on experience with test equipment such as BERTs, oscilloscopes, OSA, etc. 

  • Strong written and verbal communication skills with the ability to clearly convey complex technical topics. 

Ability to travel as needed (estimated <10%) to customer sites or company facilities; role is primarily lab-based.
