Full Stack Engineer (React + Java)

We're hiring an experienced Full Stack Engineer (React + Java) with 5-10 years of experience to design, build, and scale real-time web applications for our global B2B hotel marketplace. You'll work across the stack from building intuitive, data-driven UIs to developing high-performance backend services that power our distribution engine.

Responsibilities:

• Build and maintain end-to-end features spanning React.js frontends and Java (Spring Boot) microservices with database integrations.
• Develop responsive, performant, and accessible UIs integrated with REST and GraphQL APIs.
• Design and scale low-latency, high-throughput microservices for real-time data workflows.
• Implement event-driven systems using Kafka or SQS for asynchronous communication.
• Collaborate with Product, Design, and Architecture teams to translate business requirements into scalable solutions.
• Optimize performance through caching strategies, async processing, and database tuning.
• Implement and maintain CI/CD pipelines, test automation, and monitoring frameworks.
• Leverage AI-assisted tools (e. g., Claude, Cursor) to boost development velocity and maintain code quality.
• Participate in code reviews, design discussions, and architecture decisions.
• Write clean, maintainable, well-documented code following best practices and design patterns.

Requirements:

• 6-10 years of full-stack development experience in production-grade systems.
• Strong proficiency in React.js, JavaScript/TypeScript, and Redux (or similar state management).
• Solid backend experience in Java, Spring Boot, and Hibernate.
• Hands-on experience with databases MySQL, MongoDB, or ScyllaDB.
• Proficiency in microservices, AWS (ECS/Lambda), SQS, and GraphQL.
• Experience with event-driven architectures, Redis caching, and asynchronous processing.
• Familiarity with observability tools like Prometheus, Grafana, CloudWatch, or Sentry.
• Strong grasp of data structures, algorithms, and system design fundamentals.
• Commitment to clean code, testability, and engineering excellence.
• Strong analytical and communication skills with cross-functional collaboration experience.
• Comfortable in a remote-first, asynchronous, and ownership-driven culture.

Nice to Have:

• Experience with React Native or mobile web frameworks.
• Exposure to Kafka, Kinesis, or other event-streaming platforms.
• Familiarity with CI/CD (GitHub Actions, Docker) and container orchestration (ECS).
• Experience with AI-assisted development, LLMs, or LangChain pipelines.
• Domain exposure to B2B platforms, travel-tech, or high-scale marketplaces.
• Background in Test-Driven Development (TDD) or Agile methodologies.
