Motorola Solutions is an American company created in 2011 when Motorola split in two, taking the enterprise and public safety communications business while the handset operation became Motorola Mobility. It is the dominant supplier of land mobile radio systems to police, fire and emergency services worldwide, a business protected by long replacement cycles and deep integration with dispatch operations. Around that core the company has assembled video security and access control through the Avigilon and Pelco acquisitions, command centre software for emergency call handling and records, and increasingly AI-assisted analytics across the whole safety and security portfolio.

The market right now

Alion currently lists 424 open Backend Developer jobs in Washington from 153 companies. 84 of them were posted or refreshed in the last seven days. 137 of the employers have posted something in the last three months, which is the pool worth watching if you are starting a search now. 22 of the 424 carry the marks of a stale or abandoned posting - open far beyond the usual time to fill, reposted, or on a board that mostly never closes a role - and are marked as likely inactive; the list can hide them. Every listing links straight to the employer, so you apply on their own board rather than through an intermediary.

What these roles pay
