Senior Controls Systems Engineer
Location: El Segundo, California, United States
Employment Type: Full-Time On-Site
Package: Competitive Salary + Stock Options + Premium Benefits + Flexible PTO
Are you a Senior Controls Systems Engineer looking to step into a high-impact role at a fast-growing clean energy manufacturer?
On offer is the opportunity to develop and deliver the control systems behind a first-of-its-kind nuclear microreactor designed to provide distributed, zero-emissions power for critical infrastructure and remote operations. You'll lead the end-to-end development of algorithms, software, and control loops that ensure safe and stable reactor operation.
Join a multidisciplinary team focused on building the future of clean energy through compact, factory-built power systems. This role is ideal for engineers ready to own technically complex systems from concept through to deployment and testing.
This position would suit a Senior Engineer with deep control systems expertise who is looking to make an immediate and lasting impact.
Key Responsibilities
• Lead the development of embedded control systems for key subsystems, including generator control, reactivity management, and thermal-fluid regulation.
• Design, implement, and validate algorithms and models for system-level control performance.
• Collaborate with hardware, software, and systems teams to integrate control logic across the platform.
• Support simulation, prototyping, and hardware testing for system verification.
• Contribute to safety, stability, and regulatory documentation for critical control functions.
Essential Skills and Experience
• Bachelor's or higher in Engineering, Physics, or a related technical field.
• 5+ years of experience designing and implementing real-time control systems.
• Proficient in modern motor control algorithms, including field-oriented control and PWM.
• Strong knowledge of system stability, bandwidth design, and timing-critical architectures.
• Experience with embedded programming (C/C ) on ARM or similar platforms.
• Familiarity with field bus protocols such as EtherCAT, CANOpen, and RS-485.
• Hands-on experience with inverter systems and high-power electrical equipment.
