What We Are Looking For:
Bandwidth's Research & Development (R&D) team is at the forefront of exploring and harnessing transformative technologies to define the next generation of communication experiences. We operate as a small, agile, and T-shaped group, diving deep into emerging areas like Artificial Intelligence and Machine Learning. We're seeking a highly motivated AI/ML Engineer to join this dynamic team in our Raleigh, NC headquarters.
You thrive in a collaborative, fast-paced environment where you can rapidly iterate on ideas and prototypes. You have a startup mentality, comfortable with ambiguity and driven by a relentless curiosity to explore, build, and learn. If you're passionate about applying cutting-edge AI/ML, especially Large Language Models (LLMs), to solve real-world problems and shape future products, this is the role for you. This position requires working full-time from our Raleigh office.
What You'll Do:
- Dive deep into the latest AI/ML research, particularly in the LLM space, identifying opportunities relevant to Bandwidth's domain.
- 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.
- Experiment with various AI techniques, including advanced prompting strategies, Retrieval-Augmented Generation (RAG), and potentially agentic systems.
- Stay constantly updated on the rapidly evolving AI landscape, evaluating new tools, models, and methodologies.
- Leverage LLM-powered IDEs and development tools (like GitHub Copilot, Cursor, etc.) to accelerate the innovation cycle.
- Clearly articulate and present research findings, experiment results, and prototype demonstrations to technical and non-technical stakeholders.
What You Need:
- Bachelor’s degree in Computer Science, AI, ML, or a related technical field, or equivalent practical experience.
- 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).
- Proven experience (typically 3+ years) designing, building, and evaluating AI/ML models and systems.
- Strong programming skills, particularly in Python and familiarity with common ML libraries/frameworks (e.g., PyTorch, TensorFlow, scikit-learn, Hugging Face).
- Solid understanding and practical experience with Large Language Models (LLMs) and associated concepts, including Retrieval-Augmented Generation (RAG) and various prompting techniques (e.g., Zero-shot, Few-shot, Chain of Thought).
- 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.
- A relentless curiosity and passion for exploring new technologies and techniques in the AI/ML space.
- 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.
Bonus Points:
- 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.

What We Do
Bandwidth is a software company that’s transforming the way people communicate and challenging the standards of old telecom. Together with our customers, we’re unlocking remarkable value, questioning the status quo, and helping people interact with technology and one another, oftentimes in ways they never dreamed possible.
Haven’t heard of Bandwidth? You’ve probably used one of our products before. We power some of the most important communications technologies on the market today—names like Google, Skype and Ring Central to name a few. At Bandwidth, we’ve got a passion for doing things the other way—imagining what they could be and uncovering opportunities to take a new approach to create what should be. We’re out to disrupt the century-old rules of the telecom industry—and that means doing things differently in every area of our business. It’s in the way we treat our people, and how we create with our customers. Whether our engineering teams are crunching code during all-night hack-a-thons or our team members are competing in a Big Idea competition, we love to dive in and get our hands dirty. No idea at Bandwidth is too big or too small, and every voice gets a listen.
Our folks have diverse backgrounds from all over the world. Crave innovation? We live for it. No one here is getting a blue ribbon for shaking their head and agreeing with the higher ups. At Bandwidth, we don’t hold back. We speak our minds, share our ideas—and let them soar. We think, we dream, we reimagine what’s possible…because we know that’s the only way we can unlock remarkable value. And that’s what really gets us fired up.
