[Hiring] Full Stack Software Engineer @Papaya Global

Role Description

Papaya Global is looking for a Full Stack Software Engineer to join our team in Krakow or remotely from anywhere in Poland. Our Financial Compliance engineering team sits at the heart of that: we connect external systems, enforce data integrity, and expose reliable APIs that the rest of the platform depends on. The work is technically demanding and deeply collaborative.

• Build and maintain backend services in Java/Spring Boot - APIs, integrations with external systems, data processing and storage in relational databases
• Work with AWS services (S3, SQS, SES) as an integral part of building and connecting systems
• Contribute to frontend interfaces in TypeScript/React (roughly 20% of your time)
• Take part in technical and architectural discussions
• Write clean, well-tested code and care about it staying that way through code reviews and pair programming
• Own observability of your services
• Work closely with Product, DevOps, and other engineering teams to deliver end-to-end features
• Work in Scrum with a team that uses it as an advantage

Qualifications

• Your IDE is not an obstacle for you but an almost invisible tool – we expect fluency in IntelliJ or VSCode or (Neo)Vim
• You have solid production experience with backend systems in Java - Spring, HTTP APIs, and relational databases are core parts of your background
• You have working knowledge of frontend development in TypeScript and React
• You actively use AI-powered development tools (Claude Code, Cursor, Codex or similar) as a standard part of your development workflow
• You have working knowledge of AWS services - S3, SQS, SES
• You have experience with CI/CD pipelines and take test automation seriously
• You think about non-functional requirements - availability, reliability, security, observability
• You write clean, readable code and maintain that standard through code reviews
• Fluent written and spoken English

Requirements

• Experience building AI-powered applications — contributions in this area are welcome from day one
• Comfort working in fast-moving product teams with short delivery cycles, real demos, and tight MVP timelines
• Basic familiarity with Terragrunt or similar IaC tooling
