Full Time

Universe Sandbox is a space and gravity simulator masquerading as a video game with over 870,000 unit sales and an Overwhelmingly Positive 95% rating on Steam.

Giant Army is looking for a creative and highly technical cross-platform engineer to help put Universe Sandbox in everyone’s pocket (and, eventually, in the living room).

We are a close-knit multidisciplinary team of astrophysicists, engineers, graphics developers, and designers that highly values individual contributions and collaborative problem-solving. The company name, Giant Army, was inspired by the concept of “standing on the shoulders of giants.”

Our mission is to reveal the awesomeness of the universe and the fragility of our planet through real-time interaction, creation, and destruction of a realistic, science-based simulation.

Cross-Platform Goals

Help us solve the complex challenge of bringing Universe Sandbox to all platforms. We are getting closer to our initial mobile release (iOS & Android) and need some help pushing us over the finish line. We plan to begin console development in 2022.

We embrace responsive design and use the same UI and codebase across all platforms; desktop, AR/VR, and mobile are all built from the same project.

You might be the perfect candidate if you:

  • Enjoy solving technical challenges with multi-platform support
  • Have shipped titles on desktop, mobile, and console
  • Strive to make the user experience feel great on desktop, mobile, and console without compromise

Join us. We’re making something incredible that’s unlike anything else.

Your Role

  • Work with our team to bring the best possible experience to mobile, consoles, and future platforms, without losing desktop functionality
  • Help solve technical issues with input, performance, and overall usability
  • Plan for the future as we dive into gamepad and console support
  • Stay current on Unity’s tech and trends. We’re working on a major rewrite to be more closely integrated with Unity’s DOTS Physics.


  • Professional or personal programming projects showing your passion
  • Experience with C# & Unity (DOTS knowledge a bonus)
  • Strong attention to detail and a love of polish & iteration
  • Experience shipping titles on mobile or console platforms (ideally)
  • Unity native plugin experience (Objective-C, Java) preferred
  • Passion for science, astronomy, and real-time interactive simulations
  • Love of fantastical what-if scenarios: (note citation #6 on 148)
  • Ability to see things from our user’s perspective
  • Appreciation of video games


  • This is a full-time, remote position working with a 100% remote team
  • You will have a great deal of autonomy over your working hours
  • Health coverage for all American employees
  • We also offer optional 4 day work weeks (8-hour days)
