Job Description

We are seeking a highly skilled IBM MQ Exit Developer with strong C programming expertise to maintain custom IBM MQ exits that extend and enhance an enterprise messaging platform. This role focuses on advanced IBM MQ capabilities, including security exits, API exits, channel exits, and message exits. The developer will support authentication, authorization, message transformation, and observability requirements across distributed and hybrid environments. The ideal candidate will have deep experience with low-level C development, a strong understanding of IBM MQ internals, and the ability to deliver thread-safe, high-performance code that integrates with enterprise security and operational standards.



Responsibilities

• Maintain existing IBM MQ channel exits, API exits, security exits, and message exits using C.
• Develop and maintain thread-safe, high-performance code for multithreaded IBM MQ environments.
• Support authentication, authorization, message transformation, and observability requirements through custom MQ exit implementations.
• Integrate MQ exit logic with external systems, including LDAP and REST APIs, when required.
• Provide Level 3 support for IBM MQ exit-related issues within production environments.
• Troubleshoot complex issues involving MQ exits, messaging behavior, integrations, security, and performance.
• Partner with platform and application teams to evaluate native IBM MQ features that may reduce reliance on custom exits.
• Simplify and modernize legacy MQ exit implementations.
• Support IBM MQ migration and modernization initiatives.
• Maintain detailed technical designs, coding standards, deployment documentation, and operational runbooks.
• Ensure appropriate lifecycle management of MQ exit code, including version control, deployment, testing, and rollback procedures.
• Ensure exit implementations align with enterprise security and operational standards.

Qualifications Required Skills

• Strong hands-on C programming experience.
• Professional experience maintaining or developing custom IBM MQ exits.
• Experience with IBM MQ channel exits, API exits, security exits, or message exits.
• Strong understanding of IBM MQ internals and enterprise messaging architecture.
• Experience developing thread-safe code for multithreaded environments.
• Ability to write and maintain high-performance, low-level C code.
• Experience supporting authentication, authorization, message transformation, or observability requirements within IBM MQ.
• Experience troubleshooting IBM MQ exits in production environments.
• Experience providing advanced or Level 3 production support.
• Experience with source-code versioning, deployment, testing, and rollback processes.
• Ability to work onsite in Dallas, TX three days per week.

Preferred Skills

• Experience integrating IBM MQ exit logic with LDAP.
• Experience integrating C-based MQ exits with REST APIs or other external services.
• Experience modernizing or simplifying legacy IBM MQ exit implementations.
• Experience evaluating and implementing native IBM MQ features as alternatives to custom exits.
• Experience supporting IBM MQ migration or platform-modernization initiatives.
• Knowledge of enterprise security, authentication, authorization, and operational standards.
• Experience creating technical design documents, code standards, deployment guides, and operational runbooks.
• Experience working within financial services or highly regulated enterprise environments.

Soft Skills

• Strong analytical and complex problem-solving abilities.
• Excellent troubleshooting and root-cause analysis skills.
• Ability to collaborate effectively with platform, application, security, and infrastructure teams.
• Strong written communication and technical documentation skills.
• Ability to explain complex IBM MQ and C programming concepts to technical stakeholders.
• Strong attention to detail, especially when working with production-critical messaging systems.
• Ability to work independently while managing production support and modernization priorities.
