About the role

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.

Responsibilities

  • 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.

Qualifications

  • 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.

Education: Bachelor’s in Computer Science, Software Engineering, or related technical field, or industry equivalent experience required. Master’s degree preferred.
