About The Position

We are seeking a seasoned, hands-on Senior VoIP, VTC, and Telephony Solution Engineer to support the design, integration, validation, deployment, and sustainment of enterprise Unified Communications and Collaboration solutions. Reporting to the Voice/VTC Manager, this position will serve as a senior technical contributor and may act as the technical lead for assigned projects, workstreams, or engineering efforts. The engineer will be responsible for developing solutions to complex technical problems that span multiple systems or disciplines and for helping ensure assigned solutions are secure, resilient, supportable, and operationally ready. The engineer may provide technical direction, coordinate the work of engineers supporting an assigned project, review engineering products, and mentor less-experienced team members, but will not be responsible for employee performance management, staffing decisions, or organizational workforce planning. The successful candidate will remain actively engaged in requirements analysis, alternatives analysis, solution architecture, detailed design, laboratory validation, implementation planning, system integration, testing, and Tier 3/Tier 4 engineering escalations. The position will work closely with Transport Engineering, Network Operations, Cybersecurity, program leadership, customers, telecommunications carriers, and technology vendors.
