Calypso Developer

About the Role

Serve as a principal architect within the capital markets technology group shaping scalable hybrid solutions based on Core Java and a leading COTS product for derivatives processing. Design and optimize Calypso based back office workflows, APIs, and extensions that improve operational accuracy, reduce settlement risk, and help deliver resilient trading and post-trade platforms for global clients.

Key Responsibilities

• Design end-to-end solution architectures for capital markets systems built on Core Java and a major COTS platform to support complex trading and post-trade workflows in a scalable manner.
• Define target application and integration architectures for Calypso implementations that streamline trade capture, valuation, confirmation, and settlement flows across multiple asset classes.
• Guide detailed design of Calypso extensions and custom modules so that business-specific requirements are met without compromising performance, maintainability, or upgrade paths.
• Review and optimize Calypso API usage patterns to improve throughput, reliability, and observability while integrating with upstream trading platforms and downstream finance and risk systems.
• Create high-level and low-level design documents for hybrid deployment models that span on-premises and cloud environments, ensuring that security, resilience, and regulatory needs are fully addressed.
• Collaborate with business stakeholders, product owners, and operations teams to translate back-office processing rules into robust technical designs that reduce manual effort and operational risk.
• Provide architectural governance across multiple project streams by performing design reviews, validating non-functional requirements, and ensuring conformity with enterprise standards and best practices.
• Drive performance tuning strategies for Core Java services and Calypso workflows so that end-to-end processing meets service level objectives for latency, throughput, and cut-off times.
• Partner with quality engineering teams to define test strategies, data conditions, and automation priorities that validate complex events such as corporate actions, lifecycle events, and settlement exceptions.
• Mentor application engineers on design patterns, Calypso configuration approaches, and secure coding practices so that delivery teams build solutions that are robust, testable, and easy to operate.
• Coordinate with infrastructure and DevOps teams to define capacity, deployment pipelines, monitoring metrics, and incident response models for critical back-office platforms.
• Assess third-party components and integration options for market data, reference data, and payment systems to ensure compatibility with Calypso-based architectures and enterprise guidelines.
• Contribute to architectural roadmaps that modernize legacy back-office platforms toward modular, API-driven services that improve time-to-market and reduce total cost of ownership.

Qualifications

• Proven experience in capital markets technology with hands-on exposure to at least one major COTS trading or risk product and a solid understanding of trade lifecycle concepts.
• Strong expertise in Core Java, including multithreading, memory management, and integration frameworks applied to high-volume post-trade processing solutions.
• In-depth working knowledge of Calypso configuration, APIs, and extension mechanisms covering trade workflows, task stations, scheduled tasks, and messaging interfaces.
• Practical experience with Calypso back-office operations, including settlements, confirmations, collateral reconciliation, and investigation processes in a production setting.
• Sound understanding of relational databases, SQL, and data modeling concepts to design resilient data integration patterns for trade, cash, and position data.
• Knowledge of enterprise integration and messaging patterns, including use of queues and service interfaces within a hybrid environment that blends on-premises and cloud components.
• Familiarity with continuous integration and continuous delivery practices, code quality tools, and automated testing to support reliable and repeatable Calypso release cycles.
