• Design, develop, and maintain robust, scalable, 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.
• Conduct rigorous code reviews and vulnerability assessments, enforcing secure coding standards and ensuring compliance with organizational security policies.
• 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.
• Collaborate with architects, product owners, and cross‑functional teams to design scalable, resilient system architectures and contribute to technical design documentation.
• Mentor junior engineers, lead technical discussions, and foster a culture of continuous learning, engineering excellence, and shared accountability.
• Partner with Dev Ops teams to optimize deployment pipelines, observability tooling, and production resilience for critical trading systems.

• 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 systems.

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