Data & Analytics: Build reliable data pipelines (BigQuery) to empower analytics and ensure every cent is accounted for
Collaborate, don't isolate: While you lead the Payments zone, you’ll work closely with the wider Engineering Chapter, sharing knowledge and building the platform together
Requirements:
3+ years of commercial experience building scalable web backends
Expert with Node.js (NestJS preferred) and TypeScript
Strong experience with PostgreSQL (transactions, isolation levels) and asynchronous architectures (Queues, Event-driven)
Hands-on DevOps experience: comfortable setting up CI/CD, configuring Docker, and managing resources in Kubernetes/GCP
Revenue-driven mindset
Proactive communication
Use AI in your workflow to move faster and think broader
Nice to have:
Experience in FinTech, E-commerce, or High-load projects
Deep understanding of Payment Processing (Idempotency, Reconciliation, Fraud prevention)

Familiarity with Infrastructure as Code (Terraform)
Willingness to occasionally touch Front-end (React) to build internal tools
What we offer:
Competitive compensation

No Legacy Bureaucracy
Strong Community: Regular knowledge-sharing sessions with engineers across Skelar
Office in Warsaw or Kyiv with generator/Starlink, plus perks (lunches, gym, health insurance)
