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, Dev Ops 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 Dev Ops 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 Open Shift.
• 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 Dev Ops 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…
