Saberr believes that humanity’s greatest achievements are the product of teamwork.

Our product CoachBot delivers flexible and scalable digital coaching for teams.

We are looking for a great JavaScript developer who is proficient with React. Your primary focus will be on developing user interface components and implementing them following well-known workflows. You will ensure that these components and the overall application are robust and easy to maintain. You will coordinate with the rest of the team working on different layers of the infrastructure. Therefore, a commitment to collaborative problem solving, sophisticated design, and quality product is important.

We'll be starting recruitment conversations in mid-January.

Overall responsibilities to include:

  • Developing new features in our CoachBot webapp (frontend).
  • Building reusable components and front-end libraries for future use. We have a separate design system of components that we are trying to abstract away and use, but are not 100% there yet.
  • Translating designs and wireframes into high quality code, and collaborating closely with designers on feasibility and ideas.
  • Considering how (and if) new designs can be made accessible and usable across our target devices which span phones up to TVs/projectors.
  • Optimising components for maximum performance across a vast array of web-capable devices and browsers.
  • Peer reviewing code written by other members of the product team.
  • Helping hire other frontend developers down the line.

More specifically, in the first 3 months:

  • To gradually take over frontend development from our current two developers (who are in Serbia).
  • To help us hire another JS developer (i.e. be involved in interviews as the relationship will be very important).
  • Help us abstract key components into a design system to allow for easier reuse and faster iterations.


  • Strong proficiency in JavaScript, including DOM manipulation and the JavaScript object model.
  • Thorough understanding of React.js and its core principles. We are in the process of upgrading from 15.x to 16.x.
  • Experience with popular React workflows (we use Redux at the moment).
  • Familiarity with RESTful APIs. Our backend is in Python through Django Rest Framework.
  • Experience with common front-end development tools such as Babel, Webpack, NPM, etc.
  • Ability to work in a very collaborative team of UX designers, backend developers and a product manager.
  • A knack for writing maintainable and future proof code.
  • Familiarity with code versioning tools such as Git.


  • Competitive salary
  • Flexible working hours and locations (our office is in Angel, London)
  • Generous paid holiday policy
  • Collaborative culture with a supportive team
  • Training and conferences budget with no strings attached
  • Office with safe bike storage and showers (if that's how you roll)
  • A new MacBook Pro if they are still en vogue
