About the role

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.
And as communications shifts to AI, we're the infrastructure layer making it possible.

Design, build, and test proof-of-concepts and prototypes for novel AI-powered features and services.
Implement and integrate AI/ML models, including those based on LLMs, into potential future Bandwidth offerings.
Collaborate intensely within a small, cross-functional R&D team, sharing knowledge and contributing to a T-shaped skill set.
Proven experience (typically 3+ years) designing, building, and evaluating AI/ML models and systems.
90-Minute Workout Lunches and unlimited meetings with our very own nutritionist.

You thrive in a collaborative, fast-paced environment where you can rapidly iterate on ideas and prototypes.
Bachelor's degree in Computer Science, AI, ML, or a related technical field, or equivalent practical experience.
Experience implementing services or applications built on top of foundational LLMs (via APIs or open-source models).
Proven ability to thrive in a small, highly collaborative team environment with an urgent, results-oriented culture.
Significant experience in startups or similar fast-moving, resource-constrained organizations is highly desirable.
Experience using LLM-powered IDEs or coding assistants.
Excellent problem-solving skills and the ability to navigate ambiguity.
Must be able to work full-time from the Bandwidth headquarters in Raleigh, NC.

Master's degree or PhD in Computer Science, AI, ML, or a related field.
Experience with LLM training, fine-tuning (e.g., LoRa), and/or developing custom evaluation benchmarks.
Familiarity with advanced AI architectures and concepts such as agentic systems (e.g., ReAct), multi-modal models, Mixture of Experts (MoE), or LLM tooling/external capabilities.
Experience with MLOps practices and cloud-based ML platforms (e.g., AWS SageMaker, Azure ML, Google AI Platform).
Familiarity with AI Developer and Agentic Frameworks (e.g., OpenAI, LangChain, CrewAI, Autogen)
Experience contributing to AI/ML research, publications, or open-source projects.

100% company-paid Medical, Vision, & Dental coverage for you and your family with low deductibles and low out-of-pocket expenses.
All new hires receive four weeks of PTO.
When you take time off (of any kind!) you're embargoed from working.
Bandmates and managers are not allowed to interrupt your PTO - not even with email.
Additional PTO can be earned throughout the year through volunteer hours and Bandwidth challenges.
"Mahalo moments" program grants additional time off for life's most important moments like graduations, buying a first home, getting married, wedding anniversaries (every five years), and the birth of a grandchild.
Demonstrable expertise and hands-on experience in Artificial Intelligence and Machine Learning, with deep knowledge in at least one specific AI domain (e.g., NLP, LLMs, Speech Recognition).

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
