Job Title : VSE Apps Lead
Location : Bangalore
Experience : 8 to 10 years
Job Description :
The VSE Apps Lead is a senior-level role with expertise in VSE environments and familiarity with COBOL, Assembler, scheduler, and other applications in a mixed language environment.
This individual will take charge of the performance optimization project and lead the team in identifying and resolving performance issues within the applications running on the VSE platform.
The Apps Lead is a senior software developer with extensive experience in VSE applications programming, troubleshooting, debugging and performance analysis.
This individual will be responsible for reviewing and optimizing the applications codebase to enhance application performance and resolve identified bottlenecks especially high CPU and poor VSAM file access.
This individual will bring invaluable experience in similar roles and specific expertise in optimizing VSE applications. This individual will be able to lead and work closely with other team members such as COBOBL, assembler, scheduler and other language programmers and VSAM administrators to ensure coordinated efforts in performance optimization and achieve the project's performance objectives efficiently.
Responsibilities : - Analyze the existing COBOL applications, assembler modules, scheduler scripts, job execution patterns, and performance metrics to identify performance bottlenecks.
- Technically lead a team typically with the Lead COBOL Developer, COBOL/JCL Scheduler Developer, Assembler Developer and other team members to plan and execute performance optimization strategies.
- Conduct in-depth analysis of the VSE source code to identify areas of inefficiency, redundant code, and performance bottlenecks especially around VSAM file access and excessive CPU usage.
- Provide technical guidance and expertise in VSE-specific optimizations, best practices, and performance tuning techniques.
- Work with the team to set performance improvement targets and monitor progress throughout the project.
- Suggest and implement source code optimizations, including instructions efficiency, better call method access, algorithm improvements, data structure enhancements, and I/O access optimizations to minimize resource consumption and execution time.
- Liaise with stakeholders, including application owners and business users, to understand their performance requirements and align optimization efforts with business priorities.
- Oversee the project's timelines, deliverables, and resource allocation to ensure successful completion within the agreed-upon timeframe.
- Evaluate and recommend tools or utilities that can aid in performance analysis and optimization on the VSE platform.
- Mentor and guide team members in performance optimization techniques specific to VSE, assembler, scheduler, and COBOL.
- Test and validate code changes to ensure that the performance improvements meet the desired objectives and do not introduce new issues.
- Drive all developers to promote optimized coding practices, code reviews, and knowledge sharing.
- Monitor VSE applications performance during testing and production runs, making real-time adjustments if required to meet performance targets.
- Oversee the source code optimization process, changes made, and their impact on performance for future reference.
- Perform code reviews with other developers to share best practices and promote optimized coding practices.
- Stay updated with the latest advancements in VSE programming techniques and tools to continuously improve the performance of VSE applications.
Qualifications and Skills : - Extensive experience in VSE environments including performance issue troubleshooting and problem solving.
- Proficiency in debugging, performance analysis, and code optimization for VSE applications programs with ability for hands on support in live environments.
- Proven expertise in at least one of COBOL or assembler application development on the VSE mainframe platform, with familiarity working in mixed language environments.
- In-depth knowledge of programming language and best practices for mainframe applications preferably in VSE environments.
- Strong understanding of batch job processing, JCL (Job Control Language), and COBOL, Assembler interactions.
- Proven track record of successfully leading performance optimization projects in VSE mixed language environments.
- Familiarity with performance analysis tools and utilities specific to VSE, Assembler, Scheduler and COBOL.
- Excellent problem-solving and analytical skills to identify and resolve performance bottlenecks in COBOL applications.
- Strong communication and leadership skills to lead the team and collaborate with stakeholders.
- Strong knowledge of COBOL data structures, file handling, and VSAM interactions.
- Familiarity with mainframe environments, job scheduling, and resource utilization as well as multi-language code interactions in a mixed language environment.
- Strong experience with static code analysis and profiling tools for performance optimization.
- Strong experience with performance analysis tools and utilities on the VSE platform.
- Strong problem-solving skills and the ability to troubleshoot complex performance issues in VSE environments.
- Good collaboration skills to work effectively with cross-functional teams and stakeholders.
- Attention to detail and a commitment to lead and deliver high-quality, optimized source code.
