Kobalt is one of the world’s largest, most innovative music companies, using technology to power creative freedom, transparency, ownership and control for artists, songwriters, publishers, and labels.

Founded in 2000 by Swedish entrepreneur Willard Adhitz, the startup built a platform to maximize efficiency, accuracy, and transparency across the billions of micro-payments collected in today’s highly complex digital world. As the traditional music companies fought technology and contracted, Kobalt embraced it and grew, building an infrastructure and world-class creative team purposely designed to usher in the streaming era, along with a more fair, rewarding music business for creators.

With over 650 employees in 12 offices around the world, Kobalt today represents over 20,000 artists and songwriters, 600,000 songs and 600 publishing companies. Kobalt is proud to work with artists, songwriters, and companies like Childish Gambino, Max Martin, Paul McCartney and MPL Communications, Disney Music Group, and many more. 


We are passionate about our teams and hiring great talent. We are looking for engaged and sharp Engineers at all levels to support us with our growth ambitious.

As an Engineer at Kobalt you’ll be involved in the whole development life cycle starting with planning and roadmapping sessions with the product team, writing clean, scalable and fully tested code.

Our new developers are always mentored by an existing and more experienced member of the team and have access to an extensive range of learning materials ranging from a free Udemy account to access to a library of online e-books and audiobooks.

As a technology company we are also committed to sharing our knowledge and experiences with the wider technology community through monthly technology and diversity focussed events.


Our 100 strong engineering team is split into 4 main areas aligning to our core business units - publishing, recordings, digital collections and synch. Each of these areas is split further into smaller product or feature lead teams.

Our engineering teams find creative solutions to solve complex problems that help us provide most innovative ways for creators to distribute their work, collect their royalties, keep track of their streaming data and sync their music to TV, film and advertising opportunities that exists in the music world today.

As a Senior Engineer at Kobalt you will be responsible for working on technology problems ranging from the large scale transformation of a monolith application that processes billions of royalty payments monthly, into scalable, language agnostic services, to using predictive analysis to build recommendation engines that help our Synch team find music to fit briefs from advertising agencies from a catalogue of millions of songs.

Language is not the most important thing to us when we look for Engineers. What is important is that our engineers are adaptable, dependable, and are able to write clean, tested and reliable code. To begin with, you will likely be coding in Javascript so some experience of Javascript or a similar object oriented language will be advantageous.  

We follow best practices, test our own code and deploy our own work with the help of our operations team.

Other tech we use at Kobalt includes Node.js, PHP, Elasticsearch, Python, Java, React, Redux, AWS (and services including Lambdas and S3), Oracle, SQL (plus loads more)

This is a unique opportunity to be hands on with both the product and the technology whilst helping to shape the future of music for creators.

  • Have exceptional engineering skills preferably within a Javascript environment but any OO language is fine
  • Have experience of transferring knowledge and mentoring graduates and more junior team members
  • Be able to pivot - music is a fast moving industry to you will need to be able to change and adapt
