Helsinki, Finland

Apply now

Open source is our beating heart and it’s something that fuels our work and our culture. It’s where we began. It’s where we’ll always be. Our vision is to become the trusted open source data platform for everyone. We are a Cast of over 400 individuals (‘Crabs’) located across the globe. Why Crabs? Because we believe in thinking sideways. And right now, we’re looking for sideways-thinking Senior Backend Engineers.

The Engineering team at Aiven lies at the core of our organization. This is a great opportunity to become an integral member of the team as a Senior Backend Engineer. We look for engineers who can work around problems by finding new angles. Thinking sideways. You will have the opportunity to collaborate with world-class tech people solving the toughest problems, where almost every project you work on is more complex and technically challenging than the previous one. If you relish pushing your technical boundaries, come join us. Because if you can truly think sideways, you’ll never look back.

Who we are

So, how do we become the trusted open source data platform for everyone? By listening closely to our customers and taking action to ensure they achieve their business goals. You see, the software we create is merely a means of delivering value. Our thinking is customer-first. That’s why our customers are at the front and center of all we do. And in the spirit of sideways thinking, we’re by their side as well. Actively helping them solve their challenges. Collaborating. Sharing. And innovating. In other words, it really isn’t just about who we are. It’s about who our customers are – and where they want to be. 

Our values 

We want individuals who can embody our values of ownership, courage, and openness. 

What does that mean in practice?

We take ownership of the problems we solve. What we do is about improving life for our customers, enabling them to meet their goals. So we own our decisions and mistakes. Sometimes that takes courage. But we don’t falter – we take on challenges with confidence. And right at our heart is openness. We’re always open to new ideas – from wherever and whoever they come.
