Codesys Developer

The OMHS Automation Integration Technologies (AIT) team is building a greenfield, standardized conveyance control platform for next‑generation fulfillment centers. This role focuses on developing production‑ready CODESYS control software deployed at scale across large material‑handling facilities, using Linux‑based IPCs and Ether

CAT.

This is a hands‑on controls software role
, contributing directly to a new, modular automation architecture rather than retrofitting legacy systems.

• Develop modular CODESYS control software using IEC 61131‑3 (Structured Text & Function Blocks)
• Build reusable device abstraction libraries ("Lego Blocks") for motors, drives, sensors, actuators, and I/O
• Assemble control area applications ("Lego Sets") for conveyance units such as merges, diverts, and sortation zones
• Perform lab‑based integration, testing, and hardening of control logic
• Partner with assigned control‑area leads to deliver scalable, layered control solutions
• Produce clear documentation, runbooks, and support initial on‑site commissioning and deployments

• Hands‑on CODESYS development (mandatory; TwinCAT / Beckhoff variants not accepted)
• Strong proficiency in IEC 61131‑3 Structured Text and Function Block programming
• Object‑oriented and modular design within CODESYS
• Experience in material handling, conveyance, sortation, or industrial automation systems
• Fieldbus experience:
  Ether
  
  CAT (primary);
  Ether Net/IP or Profinet a plus
• PLC/IPC‑based controls design and industrial device integration
• Familiarity with Linux‑based industrial PCs
• Software engineering discipline:
  Git, version control, code reviews, structured testing
• Experience with layered (non‑monolithic) control architectures
