IBM Developer

Description

We’re looking for a Senior/Intermediate AS400 (iSeries) & Trimble TMS Software Engineer to stabilize, maintain, and support a mission-critical, 24/7 transportation and warehouse environment. In this role, you will absorb critical tribal knowledge from an aging contractor base, eliminate single-point-of-failure risks, and play a vital part in high-pressure system migrations and future technology roadmaps—all while operating seamlessly as a natural extension of our client's internal team.

Responsibilities

You’ll work closely with the Technology Owner, internal operations, and external vendors to deliver reliable, 100% quality-driven support for a non-stop, high-volume logistics infrastructure.

Client & Stakeholder Communication

• Provide daily updates and maintain tight-knit, direct integration with the internal technology organization.
• Act as a dependable, self-driven team member who reduces the management burden on leadership (no "babysitting" required).
• Collaborate directly with internal dispatch, warehouse operations, finance, and external EDI trading partners.

Development, Maintenance & Operations

• Maintain, troubleshoot, and enhance core transport and warehouse applications running on IBM AS400 (iSeries) and the Trimble "Innovative" TMS platform.
• Develop and maintain applications utilizing RPG (and potentially COBOL).
• Handle routine system administration, ticket handling, and infrastructure operations including:
• Onboarding new customer/vendor accounts.
• Database purging and data cleanup.
• Troubleshooting blocked or failed communications.
• Printer setup and configuration (IBM, IP-sensitive).

Project Lifecycle, Migrations & Integration

• Actively support active, high-pressure migrations, including the current Geotab to Motive telematics transition (remapping APIs, webhooks, hours of service, locations, and driver pay for ~23M messages/week).
• Assist with upcoming infrastructure milestones, including an AS400 hardware migration and a major Trimble version upgrade.
• Manage, document, and test critical EDI processing, API mappings, and third-party integrations.
• Ensure near 100% quality deployment and testing, mitigating financial workflows risk within a limited/thin test environment.

Collaboration & Knowledge Capture

• Actively engage in intensive knowledge transfer with the current veteran contractor base to document and absorb vital tribal knowledge.
• Connect securely via AWS site-to-site VPN and manage versioned programs through GitHub.

Qualifications

• Fluent English (written and spoken) with exceptional communication skills ("the 4 C's": communication, comprehension, common sense, and culture fit).
• Strong professional experience working with IBM AS400 (iSeries) environments.
• Deep hands-on experience with the Trimble "Innovative" TMS application (or closely related legacy enterprise TMS/Warehouse systems).
• Proficiency in RPG programming language (experience with COBOL is a strong plus).
• Proven experience managing EDI processing, API mapping, and data integrations.
• Strong familiarity with high-volume data streaming/messaging (handling millions of messages/transactions per week).
• Experience with AWS (specifically managing workflows over site-to-site VPN) and modern version control workflows using GitHub.
• Ability to work independently with minimal supervision, demonstrating high dependability in high-stakes, 24/7/365 production environments.
• Analytical mindset capable of reverse-engineering undocumented code and converting tribal knowledge into structured processes.

What you’ll love about us

• A fast-growing company with meaningful, mission-critical projects.
• An international, collaborative work environment.
• 5-day work week.
