Requirements

A bachelor's degree in an engineering field is required.
At least 7 years of experience as a controls engineer on complex electromechanical systems.
Mastery of programming and troubleshooting automation controllers in all IEC 61131-3-designated languages.
Ability to apply sound reasoning and considerable judgment in ambiguous situations where decisions affect large portions of a project.
Experience with control-reliable safety systems compliant with ANSI/RIA R15.06 and OSHA requirements.
Expertise in enclosure design compliant with NFPA 79, NEC, and UL 508A standards.
Familiarity with rotating machinery, cable winding, soldering, and/or pipe bending.
Experience collaborating with job shops and external vendors.

Ability to type, stand, stoop, and sit for extended periods.
Dedication to safety when working around hazards that may include heat, cold, noise, fumes, strong magnets, lead, high voltage, and cryogenics.
Willingness to occasionally travel or work required nights, weekends, or on-call.

Responsibilities

Lead initial equipment conceptual development while balancing product specifications, process-control requirements, layout complexity, and lead-time limits.
Act as the Responsible Engineer for complex equipment assets or SCADA modules, independently managing deployment through commissioning and post-commissioning stabilization.
Diagnose complex systemic equipment failures on the production floor and independently lead formal root-cause analyses to deliver long-term solutions.
Provide technical leadership on medium- to long-term problems and share expertise outside the immediate group.
Create and approve robust system architectures and electrical schematics compliant with NFPA 79, NEC, and UL 508A standards for manufacturing and test equipment, designed for modularity and reuse across future equipment.
Write and debug PLC structured text that is organized, documented, maintainable, and reusable.
Define technical requirements and documentation packages for external equipment vendors and integrators.
Contribute to department policies, tool development, and characterization of automated processes using data-driven approaches such as Cpk and Gage R&R.
Influence cross-functional peers to achieve alignment using data and rationale.
Help onboard peer employees and formally mentor junior colleagues to support their professional growth and skill development.
Identify and mitigate low- and medium-level risks, and identify larger risks and propose solutions to management.

Desired Qualifications

Experience with Beckhoff and Siemens controls platforms.
Experience with Ignition SCADA systems.
Experience integrating equipment data into SCADA or data systems, such as IO-Link and MQTT.
Machine vision experience.
Greenfield or brownfield startup commissioning experience.
Expertise with CAD drafting, specifically AutoCAD Electrical.

About Commonwealth Fusion Systems:

Commonwealth Fusion Systems is on a mission to deliver the urgent transition to fusion energy.

Combining decades of research, top talent, and new technologies, we’re designing and building commercially viable fusion power plants. And we're working with policymakers, suppliers, and many others to build the energy industry of the future.

We’re in the best position to make it happen. Since 2018, we’ve raised $4 billion of capital, making us the largest and leading fusion company in the world.

Now we’re looking for more thinkers, doers, builders, and makers to join us. People who’ll bring new perspectives, solve tough problems, and thrive as part of a team.

If that’s you and this role fits, we want to hear from you.

Join the power movement as a Senior Controls Engineer

As a Senior Controls Engineer, you are an expert in core functions and have a deep understanding of specific domains. You will take independent ownership of developing execution approaches for complex machine and process concepts, operating with little direction from management.

You will generate detailed work plans, define milestones for complex work, and define processes that impact the broader department. You will act as a technical leader, providing expertise for long-term assignments and mentoring junior engineering staff.

What you'll do:

Lead the initial equipment conceptual development while balancing product specifications, process control requirements, layout complexity, and lead time limits
Act as the Responsible Engineer (RE) for complex equipment assets or SCADA modules, independently managing deployment through commissioning and post-commissioning stabilization
Diagnose complex, systemic equipment failures on the production floor and independently lead formal root cause analyses (RCA) to deliver long-term solutions
Provide technical leadership on medium to long-term problems and share expertise outside of the immediate group
Create and approve robust system architectures and electrical schematics (compliant with NFPA79/NEC/UL508A standards) for manufacturing and test equipment, designed for modularity and reuse across future equipment
Write and debug PLC structured text with an emphasis on code that is organized, documented, maintainable, and reusable
Define technical requirements and documentation packages for external equipment vendors and integrators
Contribute to department policies, tool development, and the characterization of automated processes using data-driven approaches like Cpk and Gage R&R
Respectfully challenge and influence cross-functional peers to achieve alignment on the best path forward, leveraging data and rationale to support your point of view
Regularly help onboard peer employees and formally mentor junior colleagues to support their professional growth and skill development
Identify and mitigate low and medium risks while identifying larger risks and proposing solutions to management

What we're looking for:

Bachelor's degree in an engineering field is required
7+ years' experience as a controls engineer on complex electro-mechanical systems
Mastery of programming and troubleshooting automation controllers in all IEC 61131-3 designated languages
Proven ability to apply sound reasoning and considerable judgment in ambiguous situations where decisions impact large portions of a project
Experience with control reliable safety systems (ANSI/RIA R15.06/OSHA compliant)
Expertise in enclosure design compliant with NFPA79/NEC/UL508A standards
A reliable and persistent work ethic, seeing tasks through to completion and staying determined in the face of uncertainty and failure
Familiarity with rotating machinery, cable winding, soldering, and/or pipe bending
Collaboration experience with job shops and external vendors
High self-motivation and drive to execute quickly with excellent troubleshooting and problem-solving skills
Demonstrated commitment to design for manufacturability, serviceability, and simplicity over complexity

Bonus points for:

Experience in Beckhoff and Siemens controls platforms
Experience in Ignition SCADA systems
Experience integrating equipment data into SCADA/data systems (e.g., IO-Link, MQTT)
Machine Vision experience
Greenfield or brownfield startup commissioning experience
Expertise with CAD drafting, specifically AutoCAD Electrical

Must-have requirements:

Ability to lift up to 50 lbs occasionally
Perform activities such as typing, standing, stooping, and sitting, for extended periods of time
Dedication to safety to mitigate hazards that may include heat, cold, noise, fumes, strong magnets, lead, high voltage, and cryogenics
Willingness to occasionally travel or work required nights/weekends/on-call

#LI-Onsite

At CFS, we excel in fast-paced environments, driven by our values of integrity, execution, impact, and self-critique. As we grow, we’re eager to bring on mission-driven folks who offer diverse perspectives and fresh ways to tackle challenges.
