Senior Front End Software Engineer


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 Front-end Software Engineer.

We want to be the trusted data source data platform for everyone. But there are plenty of people out there who have not yet heard of us. And many of those who don’t yet know what we offer or what we stand for.

We therefore take marketing extremely seriously, and we are always on the lookout for those who have the creative, research, analytical and strategic skills to succeed. Currently, we are looking for a Front-end Software Engineer

At Aiven our unwavering commitment to our customers drives every facet of our marketing strategy. We believe that a truly customer-centric approach is the key to our success. Whether we're crafting compelling digital campaigns, creating engaging content, orchestrating impactful field events, or nurturing brand awareness – our customers are always at the heart of our efforts. We work seamlessly with regional sales teams and local partners to ensure that our integrated approach revolves around delivering exceptional value and experiences to our customers.

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.
