Job description

Overview
As a Full Stack Engineer at Phia, you'll build and ship features across frontend and backend systems that power our creator and brand ecosystem. You'll work on content publishing, product data, and performance tooling-learning by shipping real product, partnering closely with experienced engineers, and contributing to platforms that scale with the company.
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
  • Build and maintain frontend and backend features for internal and external tools
  • Implement APIs and data flows that support content, product, and analytics workflows
  • Collaborate with designers, product managers, and engineers to ship end-to-end features
  • Debug and improve existing systems with a focus on reliability and performance
  • Contribute to code quality, testing, and documentation
  • Learn and apply best practices for scalable, maintainable software

Qualifications
  • 1+ years of experience (or equivalent internships, projects, or coursework) in software development
  • Experience with JavaScript and at least one frontend and one backend framework
  • Basic understanding of APIs, databases, and web application architecture
  • Familiarity with version control, testing, and modern development workflows
  • Strong problem-solving skills and willingness to learn in a fast-paced environment
  • Clear communicator with a collaborative, ownership-oriented mindset
