Product Engineer (all genders)

koppla is building the next-gen collaborative scheduling platform for construction, helping project managers keep projects on time by identifying delays and disruptions before they impact timelines.
We are looking for a product-minded Product Engineer in Berlin that loves building actual products while taking ownership of the entire feature-building process.

Compensation: €65k-90k + 25% of your base salary in equity on top
Location: Berlin (Hybrid, 2+ days/week in office)

• Collaborate closely with product managers, designers and engineers to design and implement new features in a truly cross-functional process.
