Role Description

With great enterprises already deploying our GenAI-powered platform in many mission-critical use cases and unlocking huge wins, we’re investing in the next wave - more impact, smoother integrations, faster time-to-value. This is why we’re now growing our engineering team and hiring versatile Senior Backend Engineers who want to work very closely to the GenAI frontier and help build the next truly impactful product.

If all this sounds exciting and you're already actively using AI while coding and adapting your work style to these tools, let's talk.

• Excellent knowledge of SQL and relational databases
• Excellent system design skills that allow you to choose technologies and architectures wisely

• Product acumen, ownership, and focus on value delivered for the customers
• Working proficiency in English and Polish (both spoken and written)

Requirements

• Experience with Docker Swarm / Kubernetes
• Experience with NoSQL databases and GraphQL

Benefits

• Autonomy and meritocracy at the core of our values
