  • Support mobile and UC-adjacent deliverables as needed, including cross-platform mobile apps, Android/enterprise Android integrations, Cisco UC tooling, VPN diagnostics, SIP/RTP visibility, and packet-loss/network-degradation testing utilities.
  • Coordinate with application development, UC, mobile, endpoint, network, cybersecurity, database, Tier 1 support, and Government stakeholders to ensure solutions are usable, supportable, secure, and operationally aligned.
