Job Title: Intermediate/Senior Informix - HP-UX - 4GL Developer

Company: VTekis Consulting LLP

Location: Chicago, Illinois, United States

Job Type: Contract

Category: Legacy Systems Modernization / ERP Development

Date Posted: April 06, 2026

Experience Level: Intermediate/Senior (5+ years)

Remote Status: On-site

🚀 Role Summary

• Focus on modernizing a critical legacy ERP platform, bridging the gap between existing Informix 4GL logic and contemporary systems like Salesforce and e-commerce platforms.

• Drive the development and maintenance of Informix 4GL applications, ensuring system stability and performance while implementing necessary enhancements.

• Lead API build-out and integration initiatives, facilitating seamless data flow and communication between disparate systems.

• Operate within a robust Unix/Linux environment, leveraging expertise in HP-UX and other Unix-based systems for development and deployment.

• Collaborate closely with a lean, cross-functional team, including offshore resources, to achieve project objectives and maintain high standards of delivery.

📝 Enhancement Note: This role is fundamentally about legacy system modernization within a specific tech stack (Informix 4GL on HP-UX). While the prompt asks for Revenue Operations, Sales Operations, or GTM roles, this specific job listing is for a developer role focused on backend systems and IT infrastructure. The enhancement will focus on translating the developer responsibilities into an "operations" context where applicable, particularly concerning system efficiency, data integrity, and process support that underpins GTM functions. The core responsibilities are system-centric rather than GTM-strategy centric.

📈 Primary Responsibilities

• Spearhead the modernization of a mission-critical legacy ERP platform, focusing on Informix 4GL and its integration with Salesforce and e-commerce solutions.

• Design, develop, and maintain robust Informix 4GL code, ensuring adherence to coding standards and best practices for maintainability and performance.

• Implement and optimize system integrations using Genero BDL, SQL, and Unix Shell Scripting (Korn, Awk) to connect legacy systems with modern applications.

• Troubleshoot and resolve complex application issues and database performance bottlenecks within the IBM Informix Dynamic Server (IDS) environment, utilizing diagnostic tools like oncheck and set explain.

• Lead and execute integration, User Acceptance Testing (UAT), and performance testing phases to guarantee high-quality, low-disruption deployments.

• Provide essential technical support, manage incidents, and maintain comprehensive documentation for the legacy ERP system and its associated workflows.

• Collaborate daily with a small, lean team, including coordinating efforts with three offshore team members to ensure cohesive project execution.

• Support and enhance core ERP supply chain functionalities such as order creation, pick-pack-ship processes, invoicing, and Bill of Materials (BOM).

📝 Enhancement Note: While the core responsibilities are technical development, they directly impact the operational efficiency of supply chain and ERP functions. The enhancement highlights how these technical tasks support broader business operations and GTM readiness by ensuring data integrity and system availability.
