Senior Frontend Developer

We're creating a next-gen platform that will radically change the fields of facility and real-estate management. We've got the building blocks for success and now need to accelerate our product development and expand our platform. 


At Lone Rooftop we are creating the future of intelligent buildings with our next-gen realtime occupancy system called P.I.E. (Position Intelligence Engine). This combines Wifi signals and sensor data to provide users and managers with the most accurate realtime occupancy metrics. Contrary to most other startups, we didn’t start in the garage or basement, but on a rooftop. We started about 3 years ago with nothing but guts and a bold idea, and have raised a seed round last year to further develop our stack and grow the team. We are now looking for an experienced Frontend Developer to help us grow our platform.

Our challenge for you

We are looking for someone who has 3+ years of experience as a front-end developer and has a great understanding of modern web technologies and tools. We're creating single-page applications using React, Redux, Webpack and other modern frontend tools. Our team is small so we don't have time for hand-holding, but you'll be working amongst the best in our industry - among them software engineers, data scientists and product designers. Besides that, we're looking for someone who is interested in the following challenges:

  • how to visualise large data sets in real-time across a wide range of devices?
  • how to maintain UX consistency and a design system across an increasingly large number of single-page applications?
  • how to create reusable building blocks and tooling to speed up the development of new applications?
  • how can we level up our code quality without sacrificing performance or speed of development? 

Who you are

We're looking for someone to make a dent and is not afraid of a challenge. Smart, hard working and adventurous spirits please apply! We're a young company so you'll still be able to make a big impact. Candidates should at least be able to provide the following:

  • a Master's degree in Computer Science or something equivalent
  • at least 3 years of demonstrable experience in Frontend Development, preferably working on product development
  • we're a React shop, so show us your relevant React projects
