• Experience with at least one modern frontend framework (preferably Vue)

• Strong analytical skills and the ability to navigate large, complex codebases

• The ability to model, architect, and implement web solutions from conception to delivery

• A mindset focused on delivering business value to the customers, scalability, availability, performance and security across the stack

• Ability to leverage LLMs to significantly increase productivity

Why join us?

• Impact: Your work will help shape a platform used by millions worldwide

• Robust tech stack: Java / Spring / Kotlin / Vue / TypeScript / PostgreSQL / Redis

• Environment: A small team with zero bureaucracy, direct involvement with company founders, ability to learn how profitable SaaS is built

• Hybrid flexibility: We work mainly together in our Wrocław office, while staying flexible for occasional remote days when personal matters or deep-focus tasks require it

• Innovation-first: We embrace new technologies and AI-driven productivity

If you want to work on a product with a global footprint and be part of a core engineering team - we’d love to hear from you.
