Software Development Engineer

Who We Are:

At Bandwidth, we shape how the world connects. We're the global communications software company and Tier 1 network operator with global reach.  The voice, messaging, and emergency services infrastructure behind the brands and apps you use every day.

Because we own the network we build on, the problems you'll solve here are bigger, more complex, and more impactful. And as communications shifts to AI, we're the infrastructure layer making it possible.

We call ourselves BANDmates because building something this big takes collaboration, different perspectives, and the freedom to bring your authentic self to the table.

We're experts who speak like humans. Ready to build what's next? #JoinTheBand

What We Are Looking For:

The Core Voice Engineering and Technology team at Bandwidth designs, builds, and maintains the software, cloud, and network platforms that support Bandwidth’s global communication services and internal development teams.

We are looking for a Software Development Engineer (Voice Network) to join a collaborative, high-impact engineering team building the next generation of Bandwidth’s voice infrastructure and internal platform services. This role sits at the intersection of software engineering, distributed systems, cloud infrastructure, and telecommunications.

You will design and build platform APIs, backend services, and automation capabilities that abstract and manage globally distributed voice systems. You will work in an R&D-focused environment where engineers are expected to operate autonomously, explore ambiguous technical problems, build prototypes and proofs of concept, and develop scalable solutions that can be deployed across global cloud and data center environments.

While experience with networking and VoIP technologies is valuable, this is primarily a software and platform engineering role focused on building reliable, programmable, and globally scalable services for voice infrastructure.

What You'll Do:

• Design, build, and operate backend services and platform APIs that provide programmable access to Bandwidth’s voice network infrastructure and internal platform capabilities.
• Develop scalable services, orchestration capabilities, and abstraction layers for globally distributed voice systems and network services.
• Own technical initiatives from problem definition through design, proof of concept, implementation, testing, deployment, and production readiness.
• Design services for scalability, resiliency, fault tolerance, and geo-redundant global deployments.
