Senior Frontend Engineer - Developer Platform & Ecosystem 

Introduction

Do you want to be part of a team that is designing, implementing and deploying our next generation developer portal? The portal is a vital part of our support for our partners developing solutions for our highly praised open platform and will be utilizing the newest technologies for assisting our partners from idea to deployment. 

If you are into containerization, cloud services, large language models or simply just get a kick out of interacting with fellow developers on how they can best achieve their goals this is something for you.  

As AI will become an important part of not only the partner solutions but also the services in the portal itself, an interest or even experience in this area will be very beneficial. 

Team Description

We are a team of 15 people from 7 nationalities and across two sites (Copenhagen and Barcelona), working on providing the next generation developer portal for our world-leading Video Management Software.  

The team consists of all necessary functions, such as developers, test engineer, product manager, technical communication, etc, and is empowered to make decisions about the product direction based on a close collaboration with our partners. We take pride in delivering solutions with a high level of quality and based on modern technology but just as much in listening to our partners and deliver what fits their needs. 

The team culture is informal and based on collaboration between individual contributors each with a strong sense of ownership but first and foremost we believe that the best results are delivered while having fun. 

We think, plan and act as one team. As such, you will not be allocated to a group of very specified tasks. Together, we look at the tasks at hand and then decide how we best can drive things forward – and as part of this, how we best can utilize each person’s skills and competencies and at the same time ensure the on-going development of us all.

The position will be focused around providing an easy-to-use web-based frontend experience to developers and thus experience with and interest in this area is key to the position but solid knowledge about full stack development in a cloud environment will also be beneficial. 

Being a team player is crucial, and we expect a senior engineer to be able to act as a mentor and role model for more junior team members. Also, you should be able to drive and develop features both as an individual and in close collaboration with others.  

As a person you should be open-minded and willing to both share ideas with and listen to others. You should take pride in always delivering good quality solutions, be curious about learning new technologies, and be open to communicating with others both within and outside the company.

  • A software related degree at minimum B.Sc. level 
  • 5+ years of work experience as a software developer 
  • Experience with frontend development on an event-driven architecture 
  • Some experience with JavaScript/TypeScript and React 
  • Good English skills in writing and speaking 
  • It will be ideal if you also have some experience with one or more of the following: 
  • Material UI 
  • Authentication in a web-based frontend (e.g. OIDC/OAuth, JWT/claims) 
  • Frontend testing (e.g. Playwright, JEST) 
  • Micro frontends and backend-for-frontends 
  • Spotify Backstage
