We seek individuals who are passionate about innovating beyond boundaries and relentlessly pursuing solutions that protect, preserve and empower – to join us in this critical mission.  

We’re looking for team members who align with our values, mission and goals – while also meeting the minimum qualifications below. The preferred qualifications are a bonus, not a requirement.

Job Responsibilities:

• Develop and conduct system level architecture trades that include both electromechanical actuators and motion control electronics, including closed-loop systems
• Perform advanced simulations of electromechanical systems (dynamics, performance, etc)
• Decompose system requirement documents into component requirement documents
• Conduct tests and simulations to validate the performance of electromechanical systems and components.
• Own the technical input into the make / buy trade of motion control electronics, staying up to date with both internal and external offerings
• Document design processes, test results, and modifications for future reference
• Readiness to learn and receive instruction and mentorship from more experienced engineers.
• Stay up to date with the latest advancements in electrical engineering and provide guidance on future strategy of motion control electronics within the department.

Minimum Qualifications:

• Requires Bachelor's degree in a related field (or equivalent work experience in lieu of degree or Masters +3 yrs experience).
• Typically 5+ years of related experience.
• Advanced knowledge of electrical fundamentals, applicable tools, methodologies, and principles.
• Experience with simulation software like SPICE, Simsolid, MATLAB/Simulink, or similar.

• Prior experience in motor design and motor selection.
• Solid grasp of position feedback devices, such as potentiometers, resolvers, and encoders

• Intermediate knowledge of requirements management, functional requirements parsing, derivation, and allocation.
• Experience performing trade studies to support subsystem architecture decisions, including risk identification and management.

Preferred Qualifications:

• Experience serving as a Responsible Engineer (RE), driving hardware through its lifecycle, including development, qualification, integration & Test, Verification & Validation, and certification.
• Proficiency in electrical design software such as Capital, AutoCAD Electrical, Altium Designer, or similar tools.
• Ability to perform circuit analysis and troubleshooting using tools like oscilloscopes, multimeters, and logic analyzers.
• Hands-on experience in assembly, integration, and test
• Strong leadership and communication skills.

• Knowledge of electronics for spaceflight motor control applications, including:
  • Motor Types (Stepper, BLDC, 2-phase, 3-phase)
  • Telemetry types (Potentiometer, Resolver, Encoder)
  • Communication protocol (RS-422, CAN, Bilevel voltage, etc)
  • Radiation environments (LEO, MEO, GEO)
  • EEE parts (derating, classes, obsolescence, etc)

Pay Range:

Your actual base compensation will be determined on a case-by-case basis and may vary based on job-related knowledge and skills, education, experience, internal equity and market competitiveness.

At Sierra Space, we are committed to your personal and professional development. We empower you to make profound and meaningful contributions and foster a vibrant culture of collaboration, where teamwork ignites breakthrough innovations. 

 
We also offer a generous benefit package, including medical, dental, and vision plans, 401(k) with 150% match up to 6%, life insurance, 3 weeks paid time off, and more.

Application Deadline: This role will remain posted until a qualified pool of candidates is identified.
