Preference for regional/local candidates

Position Overview

Open Book Extracts is seeking an experienced Controls & Automation Engineer for a short-term project focused on upgrading and automating an existing continuous solvent extraction skid. This role is ideal for a hands-on automation professional with strong PLC programming experience who can design, develop, and implement robust control logic on an existing Beckhoff automation platform.The primary objective of this project is to transform the operation of our outdoor extraction pad from a largely operator-controlled process to a fully automated system capable of reliable steady-state operation. The selected contractor will be responsible for designing, programming, testing, and commissioning the automation logic required to achieve this goal.

Project ScopeThe contractor will lead the controls upgrade effort, including:

  • Upgrading PLC and sensor infrastructure on the outdoor extraction pad
  • Transitioning process control from manual operator intervention to automated machine-driven logic
  • Designing and implementing automated process sequencing and operational logic
  • Developing safe, reliable controls that improve consistency, throughput, and operator efficiency

Key Responsibilities

  • Design, develop, and implement PLC control strategies using the existing Beckhoff PLC platform
  • Write and modify Structured Text (ST) code within TwinCAT 3
  • Develop automated process sequencing and steady-state operating logic
  • Integrate new instrumentation and sensors, including:
    • Weight sensors
    • Flow sensors
    • Torque sensors
    • Temperature sensors
  • Configure and tune PID control loops for process stability and performance
  • Update and enhance TwinCAT HMI visualizations and operator interfaces
  • Design robust batch loading sequences and continous steady state process automation routines
  • Implement safety interlocks and fault-handling logic
  • Test, troubleshoot, and commission automation changes on existing hardware
  • Collaborate with operations and engineering personnel to validate system performance

Required Qualifications

  • Proven experience as a Controls Engineer, Automation Engineer, or PLC Programmer
  • Strong Beckhoff PLC programming experience
  • Proficiency with TwinCAT 3 development environment
  • Advanced Structured Text (IEC 61131-3) programming skills
  • Experience integrating industrial instrumentation and sensors
  • Demonstrated PID loop tuning experience
  • Experience designing automated process sequences and machine logic
  • Ability to independently develop, test, and deploy control system solutions
  • Strong troubleshooting and commissioning capabilities

Preferred Qualifications

  • Experience with batch and continuous processing systems
  • Experience in chemical processing, extraction systems, manufacturing, or industrial process automation
  • Familiarity with continuous process control environments
  • HMI development and visualization experience within TwinCAT

Work Arrangement

This is a project-based contract expected to last approximately 3–5 weeks. On-site presence in Roxboro, NC is strongly preferred during project kickoff and key implementation phases, with hybrid flexibility available as project needs allow.Success CriteriaThe successful contractor will deliver:

  • Fully automated process control logic replacing manual operator control
  • Reliable batch loading and process sequencing functionality
  • Integrated and validated sensor upgrades
  • Stable PID-controlled process operation
  • Updated TwinCAT HMI screens and operator controls
  • Safe, maintainable, and well-documented automation code running on existing Beckhoff hardware
