Job description

Job Title: Senior Mainframe Systems Developer
Role Overview
We are seeking a Senior Mainframe Systems Developer to design, maintain, and optimize mission-critical enterprise applications. You will serve as a technical lead for our high-volume batch processing systems, ensuring data integrity, system performance, and seamless integration across our financial operations.
This role is for a seasoned developer who thrives on the stability and complexity of mainframe environments. You will own the full development lifecycle-from scoping and design to coding, testing, and production support. If you are a COBOL expert who enjoys leading project phases and translating technical system logic into business-meaningful results, we want to hear from you.
Key Responsibilities
System Development & Optimization
• Technical Lifecycle: Scoping, designing, and developing complex information systems. Translate intricate business requirements into robust, high-performing code (COBOL, SQL) and system procedures.
• Batch Performance: Own the architecture and maintenance of large-scale batch processing cycles. Optimize system capacity, throughput, and response times for mission-critical operations.
• Production Support: Act as a technical escalation point for system failures and performance events. Conduct root-cause analysis to ensure long-term stability and eliminate recurring downtime.
Leadership & Strategy
• Technical Leadership: Serve as a project or technical lead for initiatives of varying scale. Mentor less-experienced programmers and guide them through technical best practices and coding standards.
• Business Translation: Act as a bridge between technical engineering teams and non-technical business partners. Ensure that system capabilities are clearly understood and aligned with organizational financial processes.
• Strategic Upkeep: Maintain a deep and evolving skill set across platforms, databases, and network utilities to support our complex technology landscape.
Qualifications & Requirements
Minimum Qualifications
• Education: Bachelor's degree in Computer Science, Business, or equivalent technical work experience (1:1 ratio for degree years/experience).
• Experience Baseline: 3+ years of systems and programming experience; 1+ years of expert-level working knowledge of COBOL.
• Technical Mastery: Proven experience with mainframe information technology environments and SQL.
• Domain Experience: Demonstrated experience with complex batch enrollment and financial data processing in a high-volume production environment.
Preferred Attributes
• Proven ability to lead large, complex project workstreams independently.
• Exceptional analytical and problem-solving skills; you are a "driver" who takes ownership of technical tasks from start to finish.
• Ability to effectively communicate technical constraints to business stakeholders to ensure realistic project delivery.
