We’re backed by top investors at the intersection of commerce and technology including The Hermès family, CEO of United Talent Agency, Fmr CEO of YZY, Partners at Quiet Capital, Streamlined Ventures, Pattern Ventures and more.

We’re at the intersection of AI, e-commerce, and celebrity culture — and we’re looking for our first Founding Full Stack Engineer to help build the future with us.

What You'll Do

As the founding engineer, you’ll work directly with the Co-Founders to own and evolve our core product — from backend architecture to user-facing features. You’ll ship fast, solve complex problems, and help define the engineering culture from day one.

Own and scale the OneOff platform (Python, NodeJS, Postgres, Javascript, Typescript, React, GCP + AI integrations)

Build performant APIs, data pipelines, and system architecture to support dynamic search and personalized feeds

Collaborate with design to bring beautiful, intuitive interfaces to life

Integrate AI and ML outputs into front-end product experiences

Build tools to ingest, parse, and standardize unstructured public fashion data (social, editorial, etc.)

Improve product performance, scalability, and UX as user traction grows

Contribute to strategic product decisions, tech stack evolution, and team hiring.

You Might Be a Fit If You:

Have 4+ years experience across both frontend and backend (React, Next.js, Node.js, PostgreSQL, Supabase, Firebase, or similar)

Are highly autonomous and thrive in 0-to-1 or startup environments

Are passionate about building polished consumer products with real-world use

Have experience working with AI/ML models, APIs, or automation tools — or are eager to learn

Love fashion, culture, or consumer tech — and want to work on something people actually talk about

Care deeply about code quality, user experience, and performance

Are excited about building something from the ground up with real ownership

Bonus (But Not Required)

You're based in Los Angeles

Experience with web scraping or data extraction pipelines

Working knowledge of vector databases, embeddings, or retrieval-augmented generation (RAG)

Previous experience at an early-stage startup or building a consumer app

Comfort working with design tools like Figma and tailoring frontend to visual polish

What We Offer

Meaningful founding-team level equity stake

Competitive salary ($150k-200k base) + healthcare benefits

Deep product ownership and creative input

Access to a network of top-tier investors, advisors, and talent partners

A front-row seat to culture, fashion, and AI innovation

A chance to help define the next generation of personalized shopping.
