Experienced Backend Engineer (Kotlin / Java)

Join one of our product teams and develop features with real value for a one-of-a-kind product management system used by 5000+ global companies.

We’re looking for a backend engineer who’s either already working at a senior level or is ready to grow into it - we’re open to experienced engineers with strong fundamentals and the ambition to take more ownership.

The Customer Centricity team at Productboard is building the backend foundations for working with customer data. The team is modeling new core entities like “Customer” and “Segment”, integrating Productboard with CRM tools, and tackling scalability challenges for enterprise use cases. We offer both full-time employment and freelance (contractor) options.

As an engineer in this team, your job is to build and evolve the backend foundations that connect product decisions to real customer data. You'll work on core systems like customer and segment modeling, data integration with CRMs, and scalable infrastructure that powers product workflows across the platform. Beyond writing code, you'll help shape how thousands of product teams understand and act on customer needs at scale.

You'll work with different functions, like product managers and designers, to bring your technical skills and understanding of product development together. This role is about making a real difference in how we build products and coming up with practical solutions that matter to our users.

This role is based in our Prague office with an office-centric hybrid schedule.
