We’re looking for a deeply technical CODESYS Controls Engineer to join a high‑caliber automation team building next-generation machine control software for industrial systems. This role is hands-on, implementation-focused, and ideal for engineers who enjoy turning well-defined architectures into robust, production-ready control logic.
⚠️ Important: This role requires direct, real-world CODESYS experience.
TwinCAT / Beckhoff-only backgrounds will not be a fit
What You’ll Be Doing
• Develop and extend machine control software using CODESYS in a layered, modular architecture
• Implement IEC 61131-3 Structured Text and Function Block–based logic with reusable libraries
• Integrate industrial hardware: motors, drives, sensors, scanners, actuators, and I/O
• Work with EtherCAT (primary), plus EtherNet/IP and Profinet
• Collaborate in a product development environment with lab validation and early deployment support
• Follow modern software practices: Git, code reviews, test discipline
• Support early deployments and travel periodically to the Seattle/Bellevue lab
✅ Required Experience
• 5+ years of hands-on CODESYS machine control development (non-negotiable)
• Strong command of Structured Text and Function Block programming
• Experience with object-oriented PLC concepts (modular FBs, reusable components)
• Integration of diverse industrial devices and field hardware
• Experience in material handling, conveyance, sortation, packaging, or manufacturing systems
• Exposure to Linux-based industrial PCs
• Comfortable working within defined architectures and layered control models
• US-based, authorized to work via a contracting firm
⭐ Preferred / Nice to Have
• Device abstraction layers or hardware interface libraries in CODESYS
• Conveyor systems experience: merges, diverts, gapping, singulation, sortation
• Warehouse, fulfillment, logistics, or e‑commerce automation background
• Knowledge of functional safety and industrial safety standards
• Familiarity with Allen‑Bradley PLCs (legacy environment)
• Python or scripting for tooling or test automation
What This Role Is NOT
• ❌ Not full-scale multi-site field commissioning
• ❌ Not high-level controls architecture or system design
• ❌ Not TwinCAT / Beckhoff rebranded as CODESYS
This role is about building real control logic, validating it in the lab, and supporting early production—not sales demos or theoretical design.
Why This Role
• Work on serious, production-grade automation software
• Highly technical team with clear architecture and standards
• Strong separation between product development and field commissioning
Opportunity to make a direct impact on industrial
