About the job

At Cosmos, we are trying to recreate the experience of working in an office for remote teams. Cosmos is a virtual world where companies can host an online office which combines a multiplayer game and video chat. We believe offices are great, but you don’t need to commute to a real world office to work together.

Full-stack engineers play a pivotal role in building experiences or solutions to customer’s direct problems and requests. They work across the entire tech stack. They have done everything from integrating productivity tools, building a DJ experience using Spotify, adding Slack integrations, creating hyper casual games such as Pong, and dealing with the nitty gritty of making a video product that works flawlessly across multiple browsers and devices.

Full-stack engineers have autonomy to shape features and work alongside designers and product people.

What you will do

  • Work with PMs, designers and engineers to decide what to build, scope and then build it
  • Build/improve the avatar creator and map making tool
  • Defining experience on mac, windows, status bar and mobile apps
  • Building the direct and group Messaging features
  • Build NPC bots to help test scalability of our video and game infrastructure
  • Improving the map UX and making the map more immersive (e.g. keyword bubbles over avatars…)
