Senior Data Engineer

We’re a global team of over 400 people, working together to push the boundaries of open-source technology and multi-cloud solutions. Our vision is to become the trusted Data & AI Platform for everyone, leveraging the most popular open-source technologies like Apache Kafka®, Aiven for PostgreSQL®, Aiven for Clickhouse®, and Aiven for OpenSearch®. to help companies accelerate time-to-market, drive efficiency, and build innovative solutions across any cloud. Right now, we’re looking for a Senior Data Engineer to join our team who shares our passion for forward-thinking and innovative approaches. 

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 Crabby Principles

Aiveners use the V2MOM framework to set and align on business goals. In order to achieve those business goals we live by our ‘Crabby Principles’ which unite us in our ways of working, globally. 

These principles are embedded in our business processes and support us in collaborating and role modelling positive and productive behaviours in our daily work, something you will have the opportunity to demonstrate throughout your interview journey with us. 

The Role:

We’re hiring a Senior Data Engineer to build and own critical components of our data platform. This is a key IC role for someone who wants to stay close to the craft while delivering reliable systems that power business decisions.

You’ll take on complex data challenges and deliver the robust, scalable solutions our teams rely on every day. The focus is on strong execution: building reusable tools, implementing clear patterns, and ensuring our data infrastructure empowers others to work faster and better.

If you enjoy working on foundational systems, solving complex technical problems, and making a tangible impact on how a business uses data, you’ll feel at home here.

Why this role exists:

We have no shortage of data. What we’re building now is the platform that turns that data into trusted, fast, and actionable insights.

We’re working on internal tooling, semantic modeling, and automated insight delivery. Whether it's building a better way to define metrics, streamlining root cause analysis, or making analytics more accessible, the problems are well-defined and have a high impact.

You’ll have a clear path to owning critical systems. This role gives you visibility into product, operations, and go-to-market initiatives that are strategic to Aiven’s growth.

What you’ll do:

• Own and deliver key data projects, collaborating closely with stakeholders from Product, Sales, Marketing, and Finance.
• Take ownership of the technical design, implementation, and maintenance of data pipelines and modeling solutions.
• Build systems that are reliable, reusable, and designed for long-term clarity.
• Contribute to architectural decisions and advocate for best practices in Python, dbt, BigQuery, and modern data tooling.
• Mentor peers through clean code, thoughtful reviews, and system design.

You might be a fit if you:

• Have a proven track record of delivering complex, large-scale data projects from design to production.
• Excel at breaking down complex business requirements into clear, actionable technical plans.
• Have built tools or systems that are essential to how your team or stakeholders work.
• Write clean, effective Python and SQL and are familiar with tools like dbt and Airflow.
• Focus on building things that last, with simple and resilient design.
• Enjoy collaborating and sharing your thinking with your peers.

Why this might be your next role:

• Visible impact. More than 40 percent of the company uses our internal data platform weekly.
• Real ownership. You’ll own significant projects from technical design to implementation.
• Strategic scope. The work connects directly to key company priorities, not just internal reporting.
• Senior culture. You’ll work with experienced peers in a low-meeting, high-autonomy environment.
• Hands-on depth. This is a long-term IC role for engineers who want to go deep and stay technical.

Don’t worry if your experience doesn’t line up perfectly – we still encourage you to apply! We believe in investing in our crabs’ professional growth.
