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.

• 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.
