Puzzel: The Low-Down

Puzzel is a leading provider of cloud-based contact center solutions, empowering businesses to deliver exceptional customer service. Our platform combines omnichannel contact center, workforce management, and AI-driven analytics to optimize customer interactions and operational efficiency.

With 25 years’ experience since our foundation in Norway, we’re already #1 in the Nordics, growing rapidly in the UK and expanding into the Netherlands and Finland in 2024, but our ambition is to become the clear European market-leader in the coming years.

What you'll do

The Senior Backend Developer will be an integral part of our Self-Service Automation development team, split across Malmö, Sweden and Sofia, Bulgaria (which is where the backend team are mostly based).

The Virtual Agent is the start of the majority of customer journeys and with the recent advances in generative AI, is technologically at the forefront of what we do. Meanwhile, Digital Engagement helps to guide prospective customers through their buyer journey on the website, which results in increased conversion of sales – inherently beneficial to any business.

Even if you’ve not worked with a directly comparable product, you should of course have an interest in this field and pushing the envelope!

It’s important to mention that this is an individual contributor role with no direct reports, so we're looking for hands-on developers at a senior level.
