Our mission is to directly connect the world’s devices (over 2 million in over 230 countries today) and enable a new era of decentralized computing. On Github, we have over 13,900 stars.

Reporting to the Head of Engineering, the Front-End Engineer role is responsible for the design and development of front-end experiences which meet the needs of our users. This role will require deep knowledge of usability, web + native UI technologies, applied to help us create and improve our responsive desktop and mobile web applications. You will regularly meet with the engineering and product team to refine feature designs, implement high-level UI components and tooling, and apply those to end-user features in our native and web applications.
If you’re interested in creating a user-friendly environment by writing code and moving forward in your career, then this job is for you. We expect you to be an experienced builder of applications for technical and business users who is curious about new and emerging digital technology and aspires to combine usability with visual design.
Our team is distributed across the US and EU, and we use modern software engineering practices and tools to support asynchronous remote collaboration. Every team member at ZeroTier is expected to work independently and leverage shared issue tracking, documentation, and automated testing to contribute to our shared base of reliable, well-defined code.
This temporary freelance position, lasting approximately three months, is based in the Netherlands—or anywhere else in the EU. If you are in the Netherlands, your primary workspace will be our office next to Utrecht Central Station; if you are elsewhere in the EU, the role will be fully remote. The engagement may be extended and could potentially transition into a permanent employment position.
