As a Senior Software Engineer - Frontend on our Data and Reporting team, you'll own the merchant-facing reporting experience that helps restaurant operators understand their business. You'll build new visualizations, evolve existing reports, and shape how thousands of merchants engage with their data daily. This role offers significant autonomy—you'll make design and implementation decisions with real impact, and your judgment will be trusted to keep the product moving forward.

On a daily basis you will:

• Design and build responsive, accessible reporting dashboards and data visualizations that help merchants make better business decisions.
• Develop new report types and chart visualizations, expanding beyond tabular data into richer visual formats.
• Improve and maintain existing reporting features, balancing new development with ongoing refinement.
• Collaborate with product managers, designers, and engineers to define requirements and deliver polished experiences—and make sound UX decisions when design resources aren't available.
• Work with backend engineers to integrate with Python APIs that power merchant reporting.
• Conduct code reviews and establish frontend standards that elevate the quality of the codebase.
• Mentor junior and mid-level engineers on frontend best practices and component architecture.

What skills are we looking for?

• 5+ years of professional frontend development experience.
• Willing to come into our Kraków or Gdańsk office 2-3 times per week.
• Strong proficiency in React, with experience building and maintaining complex component architectures.
• Demonstrated experience with data visualization libraries (D3, Recharts, Victory, Chart.js, or similar) and translating data into clear, actionable visuals.
