About The Position

PEMCCO is seeking a Transit RF / Spectrum Engineer to support the transition of a large urban multi‑modal transit system from legacy 900 MHz platforms to an 800 MHz APCO P25 communications architecture. This role advances long‑term communications resilience for a high‑ridership, safety‑critical transportation network and requires deep expertise in RF modeling, channel capacity planning, and DAS/BDA modernization. The ideal candidate will develop risk‑balanced engineering recommendations suited for complex, institutional public‑sector environments, spanning high‑density, underground, and multi‑agency interoperability contexts. PEMCCO, Inc. is an Information Technology and Information Management (IT/IM) services firm. We assist our customers in maximizing existing and emerging technologies to achieve their desired business productivity objectives. Living the Culture and Making It Happen is the motto we live by.
