Controls Hardware Engineer

Pacific Fusion was founded in 2023 with the mission to power the world with abundant, affordable, clean energy.

We are rapidly designing and building a pulser-driven inertial fusion system to achieve net facility gain (more fusion energy output than stored energy input). In parallel, we are developing the key components required to build affordable fusion systems.

Our plans are ambitious. We have raised over $900M so far from incredible investors, resourcing us to deliver on these plans. We are bringing together the best scientists, engineers, and operators from the fusion community, hard tech industry, and other sectors. We are united by a shared sense of urgency to provide clean power for the world, particularly managing climate change while meeting growing global energy demand. You can read more about us in this letter from our founders.

As a Controls Hardware Engineer, you will be an instrumental part of interfacing between project teams and gathering controls oriented requirements. Primarily you will take those requirements and design significant parts of our main control system. This role requires an individual who has a passion for controls engineering, and would like to grow in hardware design and implementation.

• Requirements & System Definition

• Collaborate with cross-functional engineering teams and system stakeholders to develop, document, and validate control system requirements

• Translate functional and safety requirements into detailed control logic, hardware specifications, and test criteria

• Participate in design and hazard reviews to ensure system requirements align with performance, safety, and reliability goals

• Control System Design and Implementation

• Develop control architectures for safety-critical and utility systems

• Design electrical schematics, control panels, and wiring diagrams for 24VDC control and 480VAC drive power systems

• Specify and integrate PLC, HMI, and communication hardware. ○ Configure and commission VFDs, servo drives, and motion control systems

• Implement and verify safety interlock and process control logic in accordance with SIS and NFPA standards

• Software Development and Integration

• Develop and test PLC programs using structured and modular programming practices

• Conduct system-level integration testing, troubleshooting, and commissioning support

• Work with instrumentation and field devices to ensure proper control and feedback integration

• Compliance and Documentation

• Ensure system designs comply with NFPA 70 (NEC), NFPA 70E, NFPA 79, and SIS/IEC 61511 standards

• Develop technical documentation including I/O lists, control narratives, functional requirements, and validation test procedures

• Support safety validation, risk assessments, and functional testing throughout the system lifecycle

• Collaboration and Technical Leadership

• Serve as a technical point of contact for controls-related aspects of multidisciplinary projects

• Work closely with fabrication, installation, and operations teams to ensure design intent and performance goals are achieved

• Contribute to continuous improvement of design methods, documentation standards, and controls best practices.
