The Opportunity

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.

What You'll Do

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.

About You

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 Else?

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 currently work in the office three days a week and will transition to five days per week by the end of the year. We were thoughtful in our approach which is based on collaboration and grounded in feedback from our workforce, leadership team, and peers. The benefits of our in office model will be shared knowledge, brainstorming sessions, communication, and building trust in-person that cannot be replicated via zoom.

Our Values

At Postman, we create with the same curiosity that we see in our users. We value transparency and honest communication about not only successes, but also failures. In our work, we focus on specific goals that add up to a larger vision. Our inclusive work culture ensures that everyone is valued equally as important pieces of our final product. We are dedicated to delivering the best products we can.
