AI Engineer Intern

Who you are

• Currently pursuing a BS/MS/PhD in Computer Science, Data Science, or a related field
• Some hands-on experience with ML systems - course projects, research, hackathons, or a prior internship all count. We are not requiring 1+ years of production experience for this role; that bar belongs on a full-time posting, not an internship
• Solid Python/Rust fundamentals: data structures, functions, basic testing, comfort reading and writing code reviews
• Exposure to at least one AI/ML frameworks (PyTorch or JAX) and basic data tooling (Pandas, SQL)
• Nice to have, not required: familiarity with a cloud platform (AWS/GCP/Azure), Docker, or a model-serving tool (vLLM, Triton, Ray Serve)
• Clear written and verbal communication. You'll be documenting your own work and asking questions across product, design, and engineering

What the job involves

• We're seeking an AI Engineer Intern to work alongside our AI team on large-scale AI and Agentic systems from data pipeline to production deployment
• This role is scoped for someone with foundational experience who wants to deepen it: you'll own discrete pieces of real systems under the mentorship of senior engineers, not shadow work or isolated coursework-style projects
• Model Development
• Partner with product managers, designers, and engineers to translate product requirements into scoped AI problem statements
• Prepare data pipeline and AI store design under senior engineer guidance
• Build and validate AI models using PyTorch or JAX(Optax/Orbax /TensorStore/Grain) and similar tools
• Run large-scale experiments, evaluate models against defined metrics, and support ablation studies and error analysis
• Productionization
• Help build inference APIs and batch scoring workflows; integrate AI outputs with backend services
• Support AIOps practices already in place on the team: model versioning, CI/CD pipelines, monitoring dashboards, and logging
• Assist with model optimization work (quantization, batching, distillation) under supervision -this is a learning objective, not an expected independent deliverable
• Operational Rigor
• Contribute to root-cause analysis on production issues alongside senior engineers
• Document experiments, design decisions, and runbooks so your work is legible to the next person who touches it
• Flag fairness, interpretability, or privacy concerns you observe in data or model behavior….you're not expected to resolve these alone, but surfacing them is part of the job
