Jobs in Baltimore, MD

About the role

In a crisis, information is the most valuable asset. When an emergency alert is triggered, the underlying technology must be invisible, instantaneous, and infallible. As the Lead Software Engineer for hardware/3rd party integrations, you aren’t just writing code; you are building the digital nervous system that protects lives. You will lead a high-impact team responsible for the final, critical mile of our service: the delivery of audio via SIP, multicast data streams, and real-time alerts to a massive fleet of connected devices and desktop agents. This role sits at the intersection of complex SaaS architecture and physical hardware integration. If you are a systems thinker who enjoys bridging the gap between cloud services and real-world devices, your work here will have a direct, tangible impact on public safety.
