Papaya Global is a rapidly growing, award-winning B2B tech unicorn with an ambitious mission to revolutionize the payroll & payments industry. With over $400M raised from multiple tier-one investors, our innovative technology provides a comprehensive solution for managing global workforces, encompassing everything from hiring and onboarding to managing and paying employees in over 160 countries.

We are 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 - distributed systems, relational data at scale, strict correctness requirements - and deeply collaborative. We're a small team, we share knowledge openly, and nobody gets left alone on hard problems.

You Will:

• 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 — infrastructure changes affect your work directly, and you'll need to understand what's under the hood.
• Contribute to frontend interfaces in TypeScript/React (roughly 20% of your time).
• Take part in technical and architectural discussions - your opinion matters, and you'll grow into bigger decisions over time.
• Write clean, well-tested code and care about it staying that way through code reviews and pair programming.
• Own observability of your services - we catch bugs from charts before users notice them, and we're proud of that.
• 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.
• Integrate AI-powered development tools (such as Claude Code, Cursor, Codex, and similar) as a standard part of your engineering workflow to accelerate development, improve debugging, enhance code quality, and support architectural thinking.
• Leverage AI-assisted workflows for code generation, refactoring, testing, documentation, and system analysis as part of daily engineering execution.
• Use AI tools to improve engineering productivity while maintaining high standards of correctness, security, observability, and maintainability.
• Your IDE is not an obstacle for you but an almost invisible tool – we expect fluency in IntelliJ or VSCode or (Neo)Vim.
  
  

Requirements:

• Solid production experience with backend systems in Java - Spring, HTTP APIs, and relational databases are core parts of your background.
• Working knowledge of frontend development in TypeScript and React, even if the majority of your time is spent on the backend.
• Active, hands-on experience using AI-powered development tools (such as Claude Code, Cursor, Codex or similar) as a standard part of your daily engineering workflow, including coding, debugging, testing, and system design support.
• Ability to effectively integrate AI tools into software development workflows to improve speed, quality, and reliability of delivery.
• Working knowledge of AWS services - S3, SQS, SES.
• Experience with CI/CD pipelines and a strong focus on test automation.
• Strong understanding of non-functional requirements such as availability, reliability, security, and observability.
• Commitment to clean, readable code and maintaining high standards through code reviews.
• Fluent written and spoken English.
  
  

Nice to have:

• Comfort working in fast-moving product teams with short delivery cycles, real demos, and tight MVP timelines — this is part of how we build new products at Papaya Global
• Basic familiarity with Terragrunt or similar IaC tooling
