Full Job Description

Position Purpose:

Serves as a hands-on programmer/analyst for the organization’s core business systems (IBM i/AS400), developing, maintaining, and modernizing the RPG applications that power the critical retirement administration platforms used by UBG. Translates business requirements into reliable technical solutions and supports the stability of mission-critical systems.
Participates in a structured knowledge-transfer program with UBG’s senior systems analyst to build deep familiarity with existing applications, data structures, and business rules, with the expectation of assuming primary development responsibility for the platform over time.
Demonstrates a proactive willingness to learn and adapt to new technologies, methodologies, and industry best practices to ensure continuous improvement and future-proofing of business systems.

Principal Duties:

RPG Development & Maintenance (45%): Develop, maintain, modernize, and extend core applications using RPG (ILE/Free), CL, and SQL. Implement fixes and enhancements to existing programs, and design database structures (DB2 for i) to support evolving business administration needs.
Business Analysis & Process Support (20%): Translate business requirements into technical specifications. Analyze existing workflows to recommend and build automated solutions that reduce manual processing time for retirement plan administration. Support user acceptance testing (UAT) for system changes.
Knowledge Transfer & Documentation (20%): Absorb and document institutional knowledge of existing systems through structured knowledge transfer. Maintain and expand system documentation in the company’s documentation repository, including program documentation, data flows, integrations, and business rules, so that systems knowledge remains current and transferable.
Operational Support & Stability (15%): Support the day-to-day operation of the IBM i environment, including scheduled jobs, file exchanges with external partners, and interfaces with non-IBM i systems. Troubleshoot and resolve production issues, and support backup, restore testing, and security procedures for mission-critical systems.

Skills/Qualifications:

Core Development: Strong proficiency in RPG (RPGLE and Free Format required; able to read and maintain fixed-format RPG III/IV), CL (Control Language), and DDS.
Database Skills: Solid SQL skills, ideally within the DB2 for i environment, including embedded SQL, query construction, and indexing; performance tuning experience is a plus.
Modern Toolsets: Proficiency using modern development tools (RDi, ACS, or VS Code for IBM i) rather than relying solely on SEU (Source Entry Utility).
Integration Skills: Ability to integrate legacy systems with modern applications via APIs, XML, JSON, or secure file transfer.
Troubleshooting: Strong debugging and problem-solving skills, including the ability to reverse-engineer undocumented legacy code to implement fixes or enhancements.
Communication & Collaboration: Excellent verbal and written communication skills. Works effectively as part of a team with the IT Manager, business analysts, senior technical staff, and external vendors, and documents work so that others can understand and support it.

Required Background/Qualifications:

Experience: Minimum of 5 years of hands-on experience in software development within an IBM i (AS/400) environment.
Full Lifecycle Experience: Proven track record across the Software Development Life Cycle (SDLC), from requirements and design through deployment and ongoing maintenance.
Data Integrity Focus: Demonstrated history of working in high-compliance or data-sensitive environments (e.g., banking, insurance, healthcare, benefits administration) where data accuracy is paramount.
Documentation Discipline: History of documenting code, data structures, and business rules so that systems knowledge is transferable rather than held by a single individual.

Preferred Background/Qualifications:

Industry Knowledge: Prior experience in the retirement administration sector (Defined Benefit/Defined Contribution plans), with an understanding of plan rules, vesting schedules, and ERISA compliance.
Legacy + Modern Fluency: Expert-level knowledge of the IBM i (AS/400) ecosystem, including RPG, ILE, CL, and FTP, coupled with modern integration skills (API, REST, SQL) to prevent system obsolescence.
Modern Integration: Experience using open-source languages (Python, PHP, Node.js) running in the IBM i PASE environment to create web-facing interfaces.
Vendor Coordination: Experience working with external MSPs, hosting providers, software vendors, or third-party developers on integrations and support issues.

Desired Background/Exposure:

GoAnywhere (File Encryption/Decryption) – maintenance of scheduled jobs for exchanging files with our 401(k) recordkeeper.
SQL Server Management Studio – maintenance of multiple databases for other internal systems, validation and verification of data to assist with troubleshooting issues on the UBG websites, adding encrypted Empower API credentials for any new UBG 401(k) Groups.
DocuWare (Document Storage) – administration of users and tasks, Workflow routing, and maintenance.
PlanetPress (Document Creation) – maintenance of letters and forms, Workflow management of the distribution of letters and forms to intended recipients.
UBG websites – assist with identifying the potential causes of reported website issues to support third-party developer resolutions, and maintenance of UBG Employer website users.

Join us to be part of a forward-thinking organization where your technical expertise will make a real difference! We value innovation, collaboration, and continuous learning—empowering you to grow professionally while contributing to impactful enterprise solutions.

Pay: $95,000.00 - $125,000.00 per year
