Sierra Space Careers: Dare to Dream

We honor those that are not afraid to dream big dreams, those that tenaciously chase their dreams even when others say it cannot be done, those that achieve big dreams and change everything. Those are Dreams Worth Chasing.  

 

At Sierra Space we envision a future where humanity lives and works in space, on moons, and on distant planets. Our mission isn’t restricted to the few, instead we see a future where all people can choose to live, work, discover and explore beyond our planet. Our company is building a platform in space to benefit life on Earth and together we will alter the course of humanity.  

We have a bold mission. We are a bold company. Together, we are an extraordinary team.

About the Role

Sierra Space is seeking a highly skilled and experienced Principal Electrical Test Engineer to lead the planning and execution of spacecraft test campaigns. This position will involve leading the electrical test engineering efforts across various spacecraft programs, ranging from Class A to Class C mission profiles, while ensuring adherence to aerospace industry standards and program-specific requirements. The ideal candidate will have expertise in medium to high-rate production programs, with a proven ability to scale testing processes effectively to meet production demands. The candidate should also have experience tailoring SMC-S-016 standards to meet program-specific requirements.

 
Responsibilities

• Lead the planning and execution of spacecraft test campaigns, ensuring compliance with program requirements and industry standards.
• Develop, implement, and oversee testing plans, procedures, and protocols for spacecraft electrical systems.
• Collaborate with multidisciplinary teams, including design, manufacturing, and systems engineering, to optimize system performance and reliability.
• Ensure rigorous testing and validation for a range of spacecraft programs, from Class A (high-reliability missions) to Class C (cost-sensitive missions).
• Support medium to high-rate production programs, developing scalable testing strategies that balance quality and efficiency.
• Analyze test data, troubleshoot issues, and provide recommendations for design improvements or corrective actions.
• Manage test equipment and facilities, ensuring proper calibration and maintenance.
• Tailor SMC-S-016 standards to meet program-specific requirements and constraints while maintaining compliance with mission objectives.
• Prepare detailed technical documentation, including test reports, procedures, and configuration management artifacts.
• Ensure compliance with all safety guidelines, government regulations, and company policies.
