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.

• 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 / Tensor Store/Grain) and similar tools.
• Run large-scale experiments, evaluate models against defined metrics, and support ablation studies and error analysis.

• 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.

• 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 documenting your own work and asking questions across product, design, and engineering.

In addition to Postman's pay-on-performance philosophy, and a flexible schedule working with a fun, collaborative team, Postman offers a comprehensive set of benefits, including full medical coverage, flexible PTO, wellness reimbursement, and a monthly lunch stipend. Along with that, our wellness programs will help you stay in the best of your physical and mental health. Our frequent and fascinating team-building events will keep you connected, while our donation-matching program can support the causes you care about.

We're building a long-term company with an inclusive culture where everyone can be the best version of themselves.

At Postman we value in person collaboration. We are in office 5 days a week for all roles based out of our hubs in San Francisco Bay Area, Boston, Austin, New York City, Tokyo and London. For roles based in Bangalore, employees…
