Java Engineer (Product / Integration)

• Design, build, and maintain Java applications with approximately 80-90% hands-on development.
• Architect and develop synchronous REST services and asynchronous event-driven integrations.
• Lead integration design patterns across multiple systems, ensuring scalable, secure, and reliable connectivity.
• Own service architecture decisions, code quality standards, and technical best practices.
• Build unit tests, maintain strong test coverage, and oversee performance testing for APIs and services.
• Troubleshoot production issues, optimize system performance, and improve reliability.
• Collaborate with product, engineering leadership, and stakeholders to translate business needs into technical solutions.
• Mentor junior and mid-level engineers through code reviews, design guidance, and best practices.
• Contribute to cloud migration, modernization, and CI/CD initiatives.

• 8+ years of professional Java development experience with strong command of core Java concepts including variables, loops, methods, classes, packages, collections, multithreading, and object-oriented design.
• Core Java reigns supreme here. Our client does not use frameworks; therefore, strong recall of core java principles, fundamentals, and problem solving is required.
• Extensive experience building and supporting synchronous integration patterns/services and asynchronous messaging/event-driven systems.
• Strong understanding of:

• Integration Patterns - scalable methods for system-to-system communication.
• Service Architecture - microservices, distributed systems, service resiliency, and maintainability.
• Service API Security - authentication, authorization, OAuth, JWT, encryption, and secure API design.
• Building REST Services - designing, developing, securing, documenting, and scaling REST APIs in Java.

• 5+ years of hands-on unit testing experience using frameworks such as JUnit / Mockito.
• Ability to interpret business requirements and create robust automated tests validating functionality.
• Strong focus on maintaining high test coverage and code quality standards.
• 3+ years of cloud experience (GCP preferred, AWS or Azure acceptable).
• 5+ years working in an enterprise environment (1,000+ employees).
• Experience working in Agile / Scrum development environments.
• Stable work history with demonstrated tenure and progression.

Nice to Have

• Real-time API development experience.
• Prior experience building REST services from the ground up.
• Experience with CI/CD pipelines and DevOps tooling.
• Experience mentoring engineers or leading technical initiatives.
• Travel, hospitality, or e-commerce industry experience.

Who Thrives Here

• Self-driven engineers who take ownership and deliver high-quality solutions quickly.
• Technical leaders who enjoy mentoring others while staying hands-on.
• Problem solvers who can modernize legacy systems while building new products.
• Engineers comfortable balancing architecture strategy with day-to-day coding.
• Team players excited to engage on-site initially, build relationships, and learn the business.
