• Familiarity with observability tools (e.g., Grafana, Prometheus, ELK stack) and logging systems for real-time data monitoring.  

• Hands on experience with rack mount servers 

• Bachelor’s degree in Computer Science, Engineering, or a related field, or equivalent practical experience.  

• 10+ years of experience in a Network SQA, Systems Engineering, SRE, or infrastructure engineering roles.  

Preferred Qualifications  

• Experience supporting hybrid systems involving embedded devices, custom hardware, or real-time control systems.  

• Knowledge of secure software deployment and Product life cycles.  

• Experience with hardware-in-the-loop pipelines or distributed lab/test automation environments.  

• Exposure to scientific computing, HPC, or quantum software stacks is a plus.  

• Ability to thrive in fast-moving, interdisciplinary R&D teams.
