Full time Software Engineer

Job Description

Kobalt was founded in 2000 with a mission: Make the music industry fairer and rewarding for creators.

We wanted to give creators, our artists, songwriters, musicians, labels and publishers, the freedom and transparency they needed to build their careers.

Today, Kobalt does exactly that. Our music technology services including Publishing, Recordings, Synchronization and the world’s first Global Digital Collection Society are trusted by some of the world’s greatest artists, and we represent more than 40% of the top 100 songs and albums in the U.S. and U.K. And it’s not just the big names we help. Our open platform allows new and upcoming artists and writers all over the world to get access to invaluable insights that help boost their musical careers.


Having undergone difficult times in the late 90s due to piracy, the music industry resurged due to streaming and curated online services and is now on a path of explosive growth as music becomes more ubiquitous than ever and distributed all over the world. Furthermore, data is today generated and collected at an unprecedented rate, through social media, marketing and other digital platforms.

As leaders in music technology, we are riding a rapid growth wave and scaling our systems and products to cope with current and future demand, while also building new innovative products that not only enable better decision making, increased efficiency but also help maximise revenue for creators.


We are looking for a senior PHP Developer to work on a variety of new and existing projects within the web team, including a staged migration of our web portal to a new platform, along with strategic improvements to improve performance and remove friction points for end users.
