Automation and Controls Engineer - Beckhoff​/Twincat

Robotic Construction Technologies (RCT) is a construction automation technology company with a mission to create the best construction system in the world and pioneer its implementation. We build large-scale robotic systems that deploy to the construction site for 3D printing homes, infrastructure, applying shotcrete, and much more. Our approach combines robotics, advanced concrete science, construction automation, and radical design simplification to deliver homes that feel high‑end without the high‑end price tag.

We are seeking an Automation & Controls Engineer to join the RCT engineering team to help design and build our flagship RCx construction ecosystem. At RCT, you will be in a high‑impact role touching design, programming, manufacturing, and on‑site operations of our RCx robotic platform and tooling. This role will have the opportunity to develop new and unique automated construction technology.

This role is on‑site in Denver, CO.

• Program and debug control logic in TwinCAT, including Structured Text, with exposure to C/C++, MATLAB, or related tools as needed.
• Implement, commission, and optimize Ether
  
  CAT‑based control schemes for motion, process, and fluid‑power systems.
• Design user interfaces that make complex machines easy to use and troubleshoot.
• Implement, commission, and optimize control schemes for motion, process, and fluid power.
• Provide hands‑on support for troubleshooting, process optimization, and manufacturing, with a sharp eye for identifying constraints, root causes, and elegant solutions.
• Support electrical design, panel layout, instrumentation selection, and electrical troubleshooting for robotic platforms, working with internal engineers, vendors, and fabricators to ensure systems are safe, maintainable, and compliant with applicable standards such as UL508A, NFPA 79, UL2011, and NFPA 70.
• Create and maintain clear engineering documentation, including I/O maps, wiring updates, control narratives, test procedures, and supporting CAD documentation in tools such as Solid Works and AutoCAD Electrical.
• Demonstrate flexibility by performing a wide range of tasks daily, including transitioning between office‑based design work and on‑site field activities as needed.
• Support electromechanical hardware systems both remotely and on‑site, ensuring safe, reliable operation.

• Degree in Computer Science, Robotics, Engineering or a related field.
• 3 to 6 years of relevant experience in automation, controls, robotics, or machine commissioning; exceptional project‑based experience will be considered in place of traditional years of experience.
• A proven drive and passion for creating and building new technology.
• Demonstrated ownership of a Beckhoff/TwinCAT‑controlled machine, subsystem, robotic cell, or field‑deployed automation project, including meaningful involvement from prototype through commissioning.
• Hands‑on experience with robotic or automated platforms, including sensors, actuators, motion systems, and control systems; exposure to localization or perception systems is a plus.
• Strong understanding of IO networks and communication, especially Ether
  
  CAT.
• Excellent problem‑solving skills and a strong analytical mindset to identify issues, propose innovative solutions, and make data‑driven decisions.
• Ability to prioritize effectively and maintain composure in a fast‑paced, start‑up environment.
• Due to the nature of some RCT contracts, only US Citizens will be considered.

• Experience with applied controls concepts such as filtering, tuning, sensor fusion, or state estimation.
• The ability to take extreme ownership of the tasks you’re assigned.
• A self‑starter’s attitude - you don’t need to be told what to do next.

• Exposure to computational geometry, toolpath generation, or geometric processing.
• Experience with the non‑industrial side of software engineering (C#, Python, Web, CI/CD).

• Must be willing to work extended hours and/or weekends as needed.

Salary Range: $110,000–$145,000 base salary, depending on demonstrated controls, Beckhoff/TwinCAT, Ether
