• Communicate complex technical concepts and information clearly to team members, senior engineers, and stakeholders, ensuring effective collaboration and successful outcomes.

Minimum Qualifications

• Bachelor’s degree in Electrical Engineering, Aerospace Engineering, or a related technical field.
• Typically 8+ yrs of related experience (6 years of experience in electrical test engineering for spacecraft or aerospace systems preferred).
• Demonstrated experience with spacecraft programs across Class A (e.g., high‑reliability, long‑duration missions) and Class C (e.g., lower‑cost, shorter‑duration missions).
• Proven expertise in medium to high‑rate production environments, with a focus on efficient and scalable testing processes.
• Strong knowledge of electrical test equipment, including oscilloscopes, spectrum analyzers, power supplies, and data acquisition systems.
• Proficiency in test automation tools and scripting languages, including COSMOS, Python, and LabVIEW.
• Deep understanding of spacecraft command and control architecture and appropriate test methods.
• Experience tailoring SMC-S-016 standards to meet program‑specific requirements.
• Excellent analytical skills and ability to interpret complex test data.
• Strong communication skills, with the ability to present findings and recommendations to technical and non‑technical audiences.
• Willing and able to obtain Active Secret Clearance (minimum).

Preferred Qualifications

• Master’s degree in Electrical Engineering, Aerospace Engineering, or a related field.
• Experience with spacecraft power systems, avionics, RF systems, or telemetry.
• Minimum of 10 years of experience in electrical test engineering for spacecraft or aerospace systems.
• Familiarity with industry standards such as MIL-STD, NASA-STD, and ECSS.
• Knowledge of environmental testing (thermal, vibration, EMI/EMC) for spacecraft systems.
• Active Secret or higher security clearance.

Compensation
