Principal Controls Engineer (Architecture)

Principal Controls Engineer (Spacecraft Controls/GNC/Precision Systems) - $180-235,000 base + benefits, Seattle

Principal Controls Engineer sought for a rapidly growing deep-tech space company developing advanced laser-based systems for next-generation spacecraft applications.

This is a rare opportunity for an experienced controls engineer to take ownership of the controls architecture behind highly complex physical systems. The focus is not simply implementing existing designs — you’ll be responsible for translating high-level system requirements into the control strategy, architecture and technical decisions that bring the system to life.

Working alongside a highly experienced engineering team, you’ll own the controls discipline across modelling, system design, hardware integration and validation. This is a role for someone who enjoys solving complex engineering problems, making architectural decisions and building systems from the ground up.

What you'll do

• Own the design and evolution of spacecraft control architectures from early concept through flight
• Translate system-level requirements into practical controls solutions, balancing performance, hardware constraints and implementation decisions
• Develop and validate control models using simulation and real-world hardware data
• Work across multidisciplinary engineering teams to integrate sensors, actuators and embedded systems
• Lead technical decisions, trade studies and design reviews for high-precision control systems
• Help build the controls discipline as the company grows

You'll likely have:

• Significant experience designing and architecting complex control systems within aerospace, spacecraft, robotics or another high-precision environment
• Strong background in motion control, feedback systems and system modelling
• Experience taking controls from simulation through hardware testing and real-world validation
• Experience working with physical systems, sensors and embedded hardware
• Ability to operate at a systems level and influence technical direction across multiple engineering teams
• Strong technical communication skills and experience documenting complex engineering decisions
• US citizenship and ability to obtain security clearance required

Ideal backgrounds could include aerospace, spacecraft, robotics, precision automation, optical systems or other high-performance engineering environments.

This role is offering $180-235K base + benefits and the opportunity to take ownership of a critical engineering discipline within a rapidly scaling space technology company.
