Job description

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.
