Senior Back-End Java Developer — Trading Platforms

We are seeking a highly skilled and hands-on  Senior Back-End Java Developer  to join a back-office trading application technology team within a leading financial institution. In this role, you will design, build, and sustain scalable, high-performance software solutions at the intersection of engineering excellence and financial technology transformation. You will champion modern delivery practices — including trunk-based development, test automation, and secure coding — while contributing to mission-critical trading infrastructure. This is a senior individual contributor and team leadership opportunity for an engineer who thrives in high-velocity, quality-first environments and is passionate about distributed systems, microservices, and continuous delivery at enterprise scale.

Design, develop, and maintain robust, scalable, and high-performance back-office trading applications following SOLID principles, clean code standards, and modern software design patterns. Implement trunk-based development practices, feature flags, and progressive delivery strategies to enable continuous integration and rapid, safe deployment cycles. Apply Test-Driven Development (TDD) and Behavior-Driven Development (BDD) methodologies to ensure high unit test coverage, code quality, and production reliability. Drive the adoption of CI/CD pipelines, DevOps practices, infrastructure as code, and automated testing to enhance system reliability and delivery velocity. Design and deliver distributed, event-driven microservices leveraging messaging platforms such as Kafka, Solace, Tibco, and MQ, with a focus on low-latency and high-availability requirements. Conduct rigorous code reviews and vulnerability assessments, enforcing secure coding standards and ensuring compliance with organizational security policies. Collaborate with architects, product owners, and cross-functional teams to design scalable, resilient system architectures and contribute to technical design documentation. Partner with DevOps teams to optimize deployment pipelines, observability tooling, and production resilience for critical trading systems. Mentor junior engineers, lead technical discussions, and foster a culture of continuous learning, engineering excellence, and shared accountability.

Strong hands-on coding proficiency in Kotlin, Java, and Python, with demonstrated experience building production-grade, enterprise-scale applications. Deep expertise in microservices architecture and system design, including Spring Boot, distributed systems, high availability, fault tolerance, and low-latency computing. Proficiency in event-driven and messaging systems — including Kafka, Solace, Tibco, and MQ — with experience designing and operating high-throughput data pipelines. Hands-on experience with containerization and cloud-native platforms, specifically Kubernetes, Docker, and OpenShift. Solid experience with relational databases, particularly Oracle SQL, within high-performance transactional environments. Proven experience with trunk-based development, feature flags, and progressive delivery in an enterprise engineering context. Strong command of TDD, BDD, and automation-first testing practices, with a track record of maintaining high test coverage in agile delivery environments. Proficiency in CI/CD pipeline design and operation, with a firm understanding of DevOps principles, secure coding practices, and vulnerability assessment methodologies. Experience conducting code reviews, leading technical discussions, and mentoring engineers within cross-functional, agile product teams. Familiarity with performance tuning, observability, and production monitoring practices in distributed, high-availability financial systems.
