Analyze on-orbit telemetry and correlate actual solar array performance with predicted power models. Provide technical support for on-orbit anomalies, troubleshooting, and root-cause investigations. Develop and manage risk mitigation plans related to solar cell technologies and solar array electrical performance. Support procurement, design, integration, and testing of spacecraft solar array photovoltaic assemblies (PVAs). Support development and qualification of new and heritage solar array hardware to meet mission‑specific requirements. Develop and review technical documentation, including requirements, test plans, test procedures, analyses, and reports. Support technical reviews and customer presentations, including PDR, CDR, TRR, MRR, and other program milestones. Maintain oversight of product‑line documentation, including qualification records, test data, performance databases, and lessons learned. Provide engineering approval and technical direction for subsystem and spacecraft design reviews. Coordinate with Systems Engineering and other subsystem teams to ensure alignment of solar array performance predictions, spacecraft power requirements, and electrical interfaces. Work directly with suppliers and manufacturing teams to resolve technical issues and ensure hardware meets design and performance requirements. Provide technical leadership and mentorship to engineers supporting solar array electrical development and operations. Required Qualifications U.S. citizenship or permanent residency required. Bachelor’s degree in Electrical Engineering. A master’s degree may be counted as two years of experience. 5+ years of engineering experience in aerospace, spacecraft power systems, solar technology, or a related field. Experience developing, testing, analyzing, or supporting electrical systems or space hardware. Strong analytical and problem‑solving skills with the ability to work through complex technical issues. Ability to work effectively in a fast-paced, multidisciplinary environment. Preferred Skills and Experience Experience with spacecraft solar array electrical design, qualification, circuit modeling, testing, and data analysis. Experience with DC circuit analysis and power system design. Familiarity with solar cell and solar array manufacturing processes and industry best practices. Experience supporting assembly, integration, and test (AIT) of electrical or spacecraft hardware in a manufacturing environment. Experience working with international suppliers and managing technical issues through design, manufacturing, and acceptance testing. Strong written and verbal communication skills, with the ability to communicate technical information effectively to engineers, program teams, customers, and senior leadership. Experience with spacecraft or aerospace industry standards and processes is a plus. Why Join Us?
