In this role, you will operate as a high-impact individual contributor, taking full technical ownership of business-critical services from architectural design through production deployment. This position is ideal for an engineer who thrives on solving complex technical challenges, writing clean, high-performance code, and building resilient distributed systems. A primary focus of this role will involve evaluating internal code bases, strategically re-engineering them to modern standards, and seamlessly integrating them with newly onboarded enterprise vendor platforms.What You Will Do Architect & Develop: Design, code, and deploy robust, production-grade backend services using Java and the Spring ecosystem. Modernize & Refactor: Analyze internal systems, identify technical debt, and strategically re-engineer code bases to meet modern software engineering patterns and cloud-ready standards. Enterprise Integration: Design and implement secure, scalable APIs and data-mapping layers to integrate our core platforms with third-party vendor software. Scale Systems: Optimize application performance, ensure high availability, and manage data consistency across distributed architectures. Own Technical Delivery: Turn complex business requirements into scalable technical designs, making critical engineering trade-offs independently. Maintain Code Excellence: Champion rigorous testing strategies, participate in deep code reviews, and continuously improve the codebase health. Ensure Resiliency: Build and test applications for failover, disaster recovery, and maximum operational stability under heavy data loads.What We Are Looking For Advanced Java Expertise: Deep understanding of core Java, JVM internals, memory management, concurrency, and performance tuning. Spring Ecosystem Mastery: Extensive production experience with Spring Boot, Spring MVC, Spring Data, and Spring Security. Transformation Experience: Proven track record of successfully refactoring and modernizing large-scale legacy code bases without causing production downtime. Integration Expertise: Strong experience designing integration layers, handling complex data translations, and connecting internal services to external third-party/vendor platforms. Distributed Systems & Streaming: Proven track record of building scalable microservices, RESTful APIs, and event-driven architectures (e.g., Kafka) with a focus on low-latency execution. Data & Caching Proficiency: Strong experience with relational databases (e.g., PostgreSQL, Oracle), schema design, query optimization, and middle-tier caching solutions (e.g., Redis). Technical Independence: Demonstrated ability to take a vague product requirement and independently design and deliver a complete, secure technical solution.Nice-to-Haves Financial Services Experience: Familiarity with banking domain, high-throughput transactional systems, middle back office platforms such as Calypso Cloud & DevOps: Hands-on experience with cloud platforms (AWS), containerization (Docker, Kubernetes), and modern CI/CD pipelines.","company":"Quinnox","rawCompany":"quinnox","city":"New York","state":"NY","isRemote":false,"isActive":false,"createdAt":"2026-07-19T12:47:35.654Z","occupations":[{"code":"15-1252.00","title":"Software Developers","slug":"software-developers"},{"code":"15-1299.08","title":"Computer Systems Engineers/Architects","slug":"computer-systems-engineers-architects"},{"code":"15-1211.00","title":"Computer Systems Analysts","slug":"computer-systems-analysts"}],"industries":[{"code":"541512","title":"Computer Systems Design Services","slug":"computer-systems-design-services"},{"code":"541511","title":"Custom Computer Programming Services","slug":"custom-computer-programming-services"},{"code":"513210","title":"Software Publishers","slug":"software-publishers"}],"jobPosting":{"@context":"https://schema.org","@type":"JobPosting","title":"Java Integration Role","description":"We are seeking an experienced Senior Software Engineer to design, build, and modernize our core backend systems.
