  • Experience supporting data center infrastructure and operations
  • Demonstrated ability to troubleshoot and resolve complex, cross-domain technical issues
  • Strong communication and customer service skills, with the ability to support both technical and non-technical users
  • Ability to work independently, prioritize effectively, and take ownership of systems and issues

Required Level of Security Clearance: None Expected Travel: 5-10% Work Environment:
  • Hybrid role based in Lanham, MD (minimum two days onsite per week)

  • Demonstrate strong problem-solving, critical thinking, and analytical skills.
  • Maintain consistent attendance, punctuality, and high professional standards.
