AI & ML Engineering Intern at Zello in Austin, TX

Summary: Zello is a voice-first communication platform that enhances collaboration for desk-less workers. They are seeking an engineering intern to build internal AI-powered tools that improve operational workflows and productivity across teams. Responsibilities: - Design and build internal AI-powered tools using LLM APIs (Claude, OpenAI), ML frameworks (PyTorch, TensorFlow), and AI-assisted development tools against Zello's data stack (Snowflake, dbt) - Identify automation opportunities by shadowing internal teams (support, ops, sales) and understanding their real pain points - Prototype quickly, ship working v1s, collect feedback from actual users, and iterate - Contribute to shared AI infrastructure — prompt template libraries, evaluation harnesses, RAG pipeline components, data connectors - Communicate technical ideas clearly, grounded in robust scientific and engineering principles - Present your work and impact to the broader team Required Qualifications: - Currently pursuing or have recently completed a degree in Computer Science, Data Science, Machine Learning, or a related technical field at a top-tier program, with a strong academic record - Built at least one working application using an LLM API — a hackathon project, a personal tool, coursework that produced real software - Understand Python and SQL deeply enough to reason about code structure, debug issues, and direct AI-assisted development tools (Claude Code, Cursor, Copilot) to produce high-quality output - Familiarity with ML frameworks like PyTorch or TensorFlow — understand model architectures and can work with existing models, not just API wrappers - Understand how embeddings, vector search, and retrieval-augmented generation work — even if you haven't deployed them at scale - Instinctively think about how to automate manual processes - Scope your own work. Given a loosely defined problem, ask good questions early, propose an approach, and then run with it Required Skills: LLM APIs, ML frameworks, Python Important Skills: SQL, Embeddings Benefits: Competitive pay, Equity with significant upside, Flexible schedules and time off, Sabbatical after every five years of service, Ping-pong table, Free snacks in our break room
