Full Time

Hidden Door is an early stage company building the future of immersive narrative entertainment. Our first product is an online multiplayer experience for playing and sharing adventures across a variety of creator-led story worlds, enabled by a new kind of narrative AI.

The role

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 software engineering, ops, 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.


  • 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.
  • Familiarity with Unity.
  • 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.
  • Familiarity with considerations for building products for kids, tweens, and teens.
  • 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, international, fully remote team, currently focused on North American and Western European time zones.
  • Sometimes we meet up! When we're able to do so safely we expect to travel a few times a year to get together for planning and fun.
  • While this is a full-time job, we are 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.
  • We value curiosity, creativity, and diverse perspectives.
  • We strongly encourage candidates from underrepresented or non-traditional backgrounds to apply.

How to apply

Please apply here! It will ask you to share a resume or your LinkedIn profile, tell us a bit about yourself, and write a story about something you've built that you're proud of and what makes you a good fit for this opportunity.
