Full Stack Developer

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 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 and 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 closely with Product, Design, and Architecture teams to translate business requirements into scalable technical solutions.
• Optimize application performance via caching strategies, async processing, and database tuning.
• Implement and maintain CI/CD pipelines, test automation, and monitoring frameworks.
• Leverage AI-assisted tools (Claude, Cursor, etc. ) to boost velocity and maintain code quality.
• Participate in code reviews, design discussions, and architecture decisions.
• Write clean, maintainable code, follow design patterns, maintain high test coverage, and document key technical decisions.

Requirements:

• 6-10 years of full-stack development experience with a proven track record in production systems.
• Strong proficiency in React.js, JavaScript/TypeScript, Redux (or similar state management) and modern frontend frameworks.
• Solid backend experience with Java, Spring Boot, and Hibernate.
• Database experience with MySQL, MongoDB, or ScyllaDB.
• Hands-on with microservices, AWS (ECS/Lambda), SQS, and GraphQL.
• Familiarity with event-driven architectures and caching layers (Redis) and asynchronous processing.
• Working knowledge of observability tools (Prometheus, Grafana, CloudWatch, Sentry).
• Understanding of data structures, algorithms, and system design fundamentals.
• Passion for clean code, testability, and engineering excellence.
• Strong analytical and communication skills with the ability to collaborate across Product, Design, and QA teams.
• 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.

Tech Stack:

• Frontend: React.js, TypeScript, Next.js, React Native, Redux, GraphQL, Tailwind CSS.
• Backend and Infra: Java (Spring Boot), Microservices, AWS ECS, Redis, ScyllaDB, MongoDB, GraphQL, AWS Lambda, MySQL, Aurora.
• Event Driven and AI: SQS, Kinesis, Claude, Cursor, LangChain.
• Observability: Prometheus, Grafana, CloudWatch, Sentry.
• Engineering Excellence: JVM tuning, GC profiling, Circuit Breakers, Async Tracing.
