Universe Sandbox is a space and gravity simulator masquerading as a video game with over 950,000 unit sales and an overwhelmingly positive 95% rating on Steam.

Giant Army is looking for a physics developer to join our team. You will work with our physics developer, team scientists, and other developers to add the necessary physics and simulation code to bring realistic, sandbox-style spacecraft to Universe Sandbox.

This is a full-time, remote position.

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

‍

‍

Your Role

• Develop and extend the rigid body physics simulation within our existing custom physics engine
• Build upon the rigid body simulation and innovate with spacecraft features such as:
• Thrusters
• Data-driven historical simulations (Cassini, Voyager, etc.)
• Modular spacecraft parts
• Destruction of spacecraft from heating, lasers, and collisions (both from other spacecraft and asteroids/planets/moons)
• Integration with our planned megastructures/tethers feature
• Soft-body deformation of objects

‍

Qualifications

• Strong C# & Unity experience (DOTS knowledge a bonus)
• Experience with physics engine development
• Familiar with version control (we use GitHub), task-management systems (we use GitHub+ZenHub), unit tests, code reviews, and so forth
• Self-driven; comfortable working collaboratively and remotely
• Appreciation for, and focus on, realism and detail
• Passion for science, astronomy, spacecraft, and real-time interactive simulations
• Love of fantastical what-if scenarios: what-if.xkcd.com (note citation #6 on 148)
• Enjoys video games; experience with physics games a plus

‍

Benefits

• 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)

Company Overview

Giant Army is a profitable company wholly owned by Universe Sandbox’s original creator. Our headquarters are in Seattle, Washington, USA, with team members across the United States, Germany, Denmark, and Australia.

Team members enjoy a flexible, collaborative environment that values work-life balance. We are independently published and release updates on our own (relaxed) schedule.

Giant Army provides generous paid time off, new hardware/software reimbursements, and other benefits.

We pursue features that get us excited about science. We strive to create an accessible experience that can’t be found anywhere else.

As a fully remote team since 2011, we rely on Google Workspace (Gmail, Calendar, Docs, Spreadsheets, Meet), Slack, Groove, GitHub, ZenHub, Unity, and WordPress.

We believe science and video games are for everyone, regardless of identity, and we’re committed to making an inclusive workplace. We encourage anyone who shares our passion for space to apply.

Product Overview

Universe Sandbox is a physics-based space simulator that allows you to create, destroy, and interact on an unimaginable scale. Experiment with gravity, climate, and collisions to reveal the beauty of our universe and the fragility of our planet.

It’s more than a game; it’s a way of experiencing and learning about reality in a way that’s never been done before.

Universe Sandbox is available on Windows, Mac, Linux, and VR with mobile in development and future platforms planned. We’ve sold over 800,000 copies and have an “Overwhelming Positive" rating on Steam with 95% positive user reviews.
