Sr. Software Engineer (AI Voice & Messaging Agents)

<p><strong>Who We Are:</strong></p> <p>At <strong>Bandwidth</strong>, we shape how the world connects. We're the global communications software company and Tier 1 network operator with global reach.&nbsp; The voice, messaging, and emergency services infrastructure behind the brands and apps you use every day.</p> <p>Because we own the network we build on,<em> the problems you'll solve here are bigger, more complex, and more impactful. </em>And as communications shifts to AI, we're the infrastructure layer making it possible.</p> <p>We call ourselves BANDmates because building something this big takes collaboration, different perspectives, and the freedom to bring your authentic self to the table.</p> <p>We're experts who speak like humans.
