Build and scale an AI-powered paywall editor used by millions: implement Next.js frontend and high-performance Python backend, integrate LLMs and APIs, deploy services globally, collaborate with founders and customers, and own features end-to-end.
The summary above was generated by AI
What You’ll Do
  • You will be building an AI paywall editor that serves millions of customers everyday, including touching the front-end Next.js application and back-end high performance Python server.
  • Integrating the latest coding models, APIs, and techniques into the editor to improve generation performance.
  • Writing and deploying Python code that serves hundreds and thousands of requests each second globally.
  • Work cross functionally with the founders, and directly with customers, to design, implement, and deliver the best experiences!
  • Wearing a lot more hats than listed above 👷.

What We’re Looking For
  • Keen problem solving skills: you are able to cut down ambiguous problems down to first principles and deliver a working solution.
  • Strong programming/full-stack foundation: You’re comfortable working on both backend code as well as frontend React code.
  • Experience working directly on user-facing products: you are able to figure out and understand what the user needs, including talking to customers
  • Stellar cross-functional communication skills: you are able to adapt to our ways of working and be an efficient/effective communicator.
  • Owning features end to end: you’ll write your own PRDs/quick specs when necessary, and you test your features end to end to make sure they work and satisfy the requirements

Nice To Haves
  • Experience with ML/AI/LLM integration in applications
  • Background working with design tools, chat experiences, or vibe coding tools
  • Previous experience founding or working at a high-growth startup
  • Mobile engineering/mobile experience is a plus

Reasons This Role Might Not Be A Fit
  • You’re uncomfortable with ambiguity, or need super structured requirements
  • You prefer to only one part of the stack, and aren’t willing to work across everything
  • You’ve never worked on systems with many moving parts: Our software has many different moving parts that you will be required to ramp up on

Requirements
You have 1-4+ years of engineering experience, with a strong track record of shipping real products.
This is a full-time, in-person role based in San Francisco - we work from the office 6 days a week (Mon-Sat)
You must be based in the Bay Area or willing to relocate before starting.
We require US work authorization, but are open to O-1 visa sponsorship for truly exceptional candidates.

Our stack:
  • Next.js (React/Typescript), Zustand
  • Tailwind/Shadcn
  • Supabase
  • Python/Fly.io
  • Mobile: Swift, Flutter, Expo
