Full Time

We're looking for an experienced engineer to help design, build, and maintain our narrative AI platform.

Hidden Door is a game technology studio building the first narrative AI — a platform that transforms any work of fiction into an infinite social roleplaying experience, bringing together players, authors and other creators.

Role overview

We're looking for a platform software engineer to help design, build, and maintain the backend for our game and platform. Our server architecture is substantially written in Python to support our machine learning systems (e.g. spaCy, PyTorch, Hugging Face).

You'll be joining our small and mighty engineering team, with opportunities to work on all parts of our system! If you're interested in working on creative experiences at the intersection of engineering, ops, narrative gaming and AI, we want to talk to you 🙂

About you

We'd love to meet if you have:

  • Experience building client-server API architectures with Python.
  • Experience with applications backed by a database.
  • Experience with infrastructure, including having shipped a production application running on at least one cloud service.
  • Informed opinions about instrumentation, monitoring, and observability.
  • Excellent written and verbal communication, with a love of close collaboration.

And it'd be ideal if you also have:

  • Architected complex backend applications that have scaled gracefully over time.
  • Designed beautiful public APIs used in production by multiple consumers.
  • Experience designing, deploying, and scaling relational and NoSQL databases.
  • Good taste in picking the right tools for the job, to help us make several infrastructure and tool choices in the near future.
  • Background in consumer-facing mobile, web, social, or game engine apps.
  • Passion for telling stories and playing games — even better if you've written stories or worked on a game of any type!
  • Interest in building applications with machine learning and natural language processing.

Other things to know

  • We're a small, fully remote international team, focused on North American and Western European time zones.
  • Several times a year, the whole team gets together IRL for planning and fun. Recently we've been to New Orleans and Lisbon!
  • While this is a full-time position, we're flexible about working hours and trust you to bring your best. Both co-founders have young children and we are committed to a healthy, balanced life.
  • This is a startup 😉 We're building a company together as much as we are building a game together, and we want your help.
  • We value curiosity, creativity, and diverse perspectives.
  • We strongly encourage candidates from under-represented or non-traditional backgrounds to apply.

How to apply

Our application form will ask you to provide a resume or LinkedIn profile, tell us a bit about yourself, and share a story about something you've built that you're proud of and how it makes you a good fit for this opportunity. If you run into any issues, just email us.

Hidden Door

Hidden Door is building the narrative multiverse at the intersection of machine learning and immersive entertainment. Launching in 2022, our first product is a social game platform for playing stories with friends across a variety of shared creative universes. Our mission is to inspire creativity through play with AI, using natural language, vibrant art, and playful social storytelling experiences.

Our underlying technology platform is built on extensible proprietary models of language and art, based on millions of stories. Through its APIs, developers can build online experiences for interactively improvising new stories together with groups of players, while adhering to rigorous content and safety standards. In the future, this will enable creators to automatically adapt existing works for this new medium.

Founded in early 2020 by Hilary Mason and Matt Brandwein, we're proud to be backed by Northzone, Makers Fund, Betaworks, Brooklyn Bridge Ventures, Homebrew, and angels Dan Sturman (CTO of Roblox) and Joshua Schacter (founder of

Featured Game

A new kind of social roleplaying experience, powered by narrative AI.

Hidden Door's first product is social game platform for playing stories with friends across a variety of shared creative universes.

Friends team up to remix story worlds styled as interactive graphic novels. With the storytelling vibe of a tabletop roleplaying game — including a playful AI narrator — anyone can improvise endless adventures together with a host of responsively generated NPCs, items, and locations. These, in turn, can be collected, traded, and shared with friends to remix into new worlds and stories. In the future, the game will expand to include a marketplace for content from professional writers, artists, and other players.
