For quick apply, please reach out to Saurabh Kapoor at 248-582-6559/saurabh.kapoor@stefanini.com

We are responsible for designing, developing, testing, maintaining, and supporting critical software applications and products to meet customer needs. As an integral part of the Vehicle Order Processing and Control Product team, they are involved in the entire software development lifecycle (SDLC)-including business analysis, technical consultation, designing robust backend and integration software architectures, writing code (COBOL, JCL, Java), testing for quality, and deploying system updates. This role focuses on developing and maintaining backend mainframe components (DB2, IMS, stored procedures, MQs, REST services) and their integration points with Java-based systems to ensure seamless, end-to-end transaction processing. 

Responsibilities

• Work on continuously improving performance and optimizing applications-including recommending and executing DB2 database performance tuning actions-and implementing new development tools (such as Endeavor) to maximize engineering efficiency. 
• Familiar with programming practices-such as test-driven development (TDD), continuous integration, and continuous delivery (CI/CD) - adapting these methodologies to a hybrid Mainframe and Java backend ecosystem. 
• Support security practices to safeguard critical vehicles, order, and customer data, ensuring proper encryption, secure APIs, and data anonymization across both mainframe (DB2) and non-mainframe (SQL Server) databases. 
• Enable user-friendly and interactive interfaces by developing highly performant and reliable backend APIs, data access layers, and communication channels (MQs, stored procedures) that power frontend consumer applications. 
• Develop and maintain back-end applications like APIs, microservices, and database layers using server-side languages, COBOL stored procedures, IMS transactions, and SQL Server integration. 
• Evaluate and incorporate emerging technologies and capabilities (such as hybrid-cloud integration, DB2 REST services, and modern mainframe tooling) to deliver solutions, monitoring and participating in new stack layers often involving industry collaboration. Operational Requirements Provide off-hours production support as required for the North America Eastern Time Zone.

Experience Required

• 5 to 10 years of hands-on experience in Mainframe development, systems analysis, and production support across all phases of the SDLC. Extensive experience with COBOL, DB2, JCL, VSAM, IMS, and REXX in both Batch and online transactional environments. 
• Assess the requirements of mainframe applications and services to determine the most suitable technology stack, integration methods (such as DB2 REST services, Message Queues (MQs), and microservices), and deployment strategies. Create high-level software architecture designs that outline the overall structure, components, and interfaces of applications, specifically defining how Java-based systems securely and efficiently communicate with DB2 back-end databases. 
• Strong experience managing DB2 stored procedures, DB2 REST services, Message Queues (MQs), SQL Server, and Endeavor. 
• Ability to visualize, query, and work with both mainframe (DB2) and non-mainframe (SQL Server) data structures. 
• Some experience with Java, with a strong focus on how Java applications interface with DB2 databases (e.g., via COBOL stored procedures, MQs, or RESTful services). 
• Proven experience working in highly collaborative, Agile software development teams with a strong drive for results.
