Job description
Wroclaw | Ivano-Frankivsk | Worldwide
The projects you will be matched to sit at the intersection of ticketing systems and financial operations. End users span both businesses (B2B integrations, white-label platforms, operator dashboards) and consumers (B2C checkout flows, booking interfaces, transaction histories).
The nature of our projects is mixed: some involve greenfield development of new features and services, while others require working within and modernising existing legacy codebases. You should be equally comfortable navigating both - writing clean new code and carefully refactoring or extending existing code.
Depending on the project, you may work as part of a client’s embedded engineering team or as part of our own delivery squad. Team sizes vary. What stays constant is the expectation that you bring genuine full-stack capability, take ownership of your work, and communicate clearly with everyone around you.
Requirements:
Strong experience with Node.js and Express.js and/or Nest.js (5+ years) , demonstrating a deep understanding of event-driven architecture, async patterns, server optimization, and production-grade API development;
Experience with database technologies, including PostgreSQL or MySQL RDS with proven ability to design complex schemas, optimize queries, implement efficient data access patterns, and leverage Redis caching understanding (read-through, write-through) of high-traffic applications;
Hands-on expertise with tools like OpenAPI/Swagger/GraphQL, Postman and processes for API contract testing;
Strong proficiency with React ecosystem (5+ years) , including deep knowledge of React hooks, component lifecycle, advanced state management patterns (Redux/Context API), performance optimization, and complex UI system design;
Solid experience with modern frontend build pipelines, bundlers (Webpack, Vite), module systems, and optimization techniques for production environments;
Advanced skills with CSS/CSS-in-JS frameworks (e.g. Tailwind, Styled-Components) and design system tools (Figma or Storybook);
Experience developing complex full-stack applications with microservices and/or serverless approaches, ensuring scalability and maintainability will be a plus;
Demonstrated experience implementing and designing RESTful or GraphQL APIs following best practices;
Experience with integrating third-party services . Understanding of modern integration patterns;
Good knowledge and practical application of OOP, SOLID principles, design patterns , and enterprise integration concepts (versioning strategy, naming convention strandards, etc.) in production environments;
Following and optimizing coding standards, architecture patterns/styles, and development best practices across teams;
Upper-intermediate English level sufficient for technical discussions, documentation writing, code reviews, and effective team collaboration in an international environment;
Proactivity and continuous learning (demonstrated ability to research and come up with possible problem solutions, stay ahead of emerging trends, especially in AI and cloud technologies).
Will be a plus:
Experience with developing AI-powered features using APIs (OpenAI, Claude), integrating GitHub Copilot workflows;
Experience with AWS/Azure/GCP microservice-based architectures with Docker containers and Kubernetes/ECS orchestration, backed by IaC CI/CD pipelines;
Experience with Serverless Framework or AWS SAM;
Knowledge of GraphQL;
Experience with code audit would be a big plus: Handling audit process through stages like (static analysis -> manual review -> remediation tracking) and provide deliverables like risk map, remediation plan;
Conducting code audits for security vulnerabilities (static code analyzers like SonarQube, Snyk, dependency vulnerability scanning), performance bottlenecks, and technical debt assessment, with knowledge of industry security standards and compliance requirements.
Knowledge of service workers, offline caching strategies and PWA best practices.
