Balena is developing Jellyfish, an ambitious social knowledge database that the team uses to collaborate, without being blocked by departmental or hierarchal divisions. Jellyfish gathers all information company wide and makes it a platform to implement processes that enhance the team's productivity and understanding. Think of it as a cross between Slack and Excel!

The improved problem space visibility and communication flow that the platform provides to the team is then leveraged to help build and improve both internal and customer facing products. Multiple teams across the company are already relying on the Jellyfish platform for their daily tasks.

Jellyfish adopts a revolutionary and cutting edge architecture:

  • The external interface is based on JSON Schema and JSON Patch
  • Actions on the system are asynchronous by default
  • The UI is auto-generated based on the data
  • It can seamlessly integrate with external services such as GitHub and Discourse

The Jellyfish team consists of a small group of tight-knit engineers who take pride on moving hyper fast without sacrificing quality by investing on automation, testing, and great engineering practices.

In this role, you will be using React to automatically generate user interfaces that can be used to view (and work together on) the compiled knowledge from many different perspectives.


  • Actively invest back in our own technology, libraries, and frameworks
  • Be highly motivated to produce great code
  • Understand security best practices and strive to apply them in your work
  • Evaluate user requirements and other inputs to determine the scope and timing of new functionality
  • Push for delivering delightful user experiences
  • Closely collaborate with our UX/UI designers
  • Move between all major operating systems to ensure we provide consistent experiences
  • Unify how balena builds user interfaces, and actively contribute to Rendition, our shared GUI/CLI components toolkit
  • Use automation to reduce the amount of UI code that needs to be written


Need to have:

  • Desire to make yourself and others more effective. You'd be bothered by an inefficient process
  • Good understanding of software engineering practices and how to apply them
  • Excellent written communication skills, and fluency in English
  • Self-discipline to take on a project and push it to completion without too much management. You also know when to ask for help
  • Highly organized, able to handle many threads at once, and keep things moving
  • Experience with Node.js
  • Experience building single-page applications with React, or any similar modern framework
  • Strong testing skills
  • Understanding of the command-line interface
  • Understanding of backend systems and how they interact with front-end applications

Nice to have:

  • A sample of your work (URL or attached sample)
  • Contributions to OSS projects (please include a URL)
  • Having worked remotely before
  • Experience with balena as a user
  • Experience with embedded GNU/Linux, anything ranging from personal projects with a Raspberry Pi to commercial or industrial scenarios with custom devices
  • Experience building automation tools
  • Experience building productivity software

Make sure to let us know if any of these items apply to you!


We come from 15+ countries, and we embrace a remote culture with flexible hours. To us, this means being highly productive while still maintaining a healthy work-life balance. You need to be able to work remotely, and have a dependable internet access available so you can join video calls.

We are an equal opportunity employer and value diversity. We value knowledge and initiative more than educational and personal backgrounds, age, or location. We maintain a work environment in which team members are treated with respect at all times and in which thoughts and ideas can be shared openly.

We communicate proposals, discuss with others in the team and accept feedback if it makes the result better. We value the ability to learn, which is more important to us than knowledge of specific technologies. We know that learning fast means being outside our comfort zone, which is OK -- we'd rather learn than let our assumptions get in our way.


  • Work with an extremely talented, diverse team
  • Equipment of your choice
  • Remote-friendly
  • Flexible working hours
  • Generous vacation policy
  • Annual company gathering in an international location - this year, Barcelona in October
  • We send you hardware for side projects!


We're delighted to hear about you! Send us your CV, with a focus on what you can bring to the team. Please include in your cover letter a paragraph about something you worked on that you found technically appealing or exciting.
