They are seeking a highly motivated AI/ML Engineer to join their Research & Development team to explore transformative technologies and develop novel AI-powered features and services.

Responsibilities : • Dive deep into the latest AI/ML research, particularly in the LLM space, identifying opportunities relevant to Bandwidths 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.

Qualifications : Required : • 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.

Preferred : • 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.
