Full Job Description

OVERVIEW As a Full Stack Engineering Intern at Phia, you will help build and ship product features that power our creator and brand ecosystem. You will work across the stack to develop user-facing experiences, support product data systems, and improve the internal tools that enable content publishing and performance insights. Partnering closely with engineers, product managers, and designers, you will contribute to real projects that directly impact our community. This internship offers hands-on experience building scalable systems in a fast-moving startup environment while learning engineering best practices from a high-performing team. ABOUT PHIA Phia has raised $43M from Notable Capital, Khosla Ventures, and Kleiner Perkins, with backing from founders and operators like Vlad Tenev (Robinhood), Mellody Hobson (Ariel Investments), Naomi Gleit (Meta), and Mati Staniszewski (ElevenLabs), plus a roster of cultural leaders, to build the AI alignment layer for commerce. In just over a year, Phia's consumer shopping agent has surpassed 1.5 million users and partnered with 9,600+ retail brands across contemporary, resale, and luxury, representing billions in annual gross merchandise volume. We scan more than 350 million products to help shoppers find the right pieces at the best price, cutting return rates by 50%, and we're on pace for nine-figure sales growth this year.   In an era where AI vertical agents are reshaping every industry, commerce is on the verge of a complete transformation. Phia is reinventing shopping from a fragmented, impersonal experience into one that feels intelligent, trusted, and built around each user's intent. This foundation of trust is our wedge to become the end-to-end shopping destination for the next generation of buyers.   Phia is a lean, high-ownership team building at startup speed. If you want to ship at high velocity and solve complex problems in consumer AI and commerce, this is the place to do it. WHAT YOU OWN - Contribute to fronten
