Senior Solar Array Regulator Responsible Engineer – TeraWave

About the role

TeraWave is developing a revolutionary satellite communications network with a constellation of optically interconnected satellites in low Earth orbit (LEO) and medium Earth orbit (MEO). The TeraWave Spacecraft Bus Electrical Power Subsystem team is seeking a Responsible Engineer (RE) for the Solar Array Regulator (SAR).

Responsibilities

• Own the full design, development, qualification, and production release of the Solar Array Regulator, including requirements derivation, circuit design, schematic capture, layout oversight, and design verification.
• Define and maintain hardware requirements, interface control documents (ICDs), and design specifications in coordination with systems engineering and adjacent subsystems (thermal, structures, harness, avionics, and solar array).
• Lead solar array regulation circuit design — including sequential switching shunt regulators (S3R), peak power tracking (PPT) or maximum power point tracking (MPPT) topologies, bus voltage regulation, and protection circuits — for a high-voltage spacecraft power bus.
• Characterize solar array electrical performance across illumination angles, temperature ranges, and eclipse/sun transition scenarios to inform SAR design margins and control algorithms.
• Design for constellation-scale production: optimize for manufacturability, testability, component availability, and unit cost while meeting reliability and performance requirements.
• Own qualification testing per applicable standards (MIL-STD-1540, SMC-S-016, or equivalent), including test plan development, execution oversight, and anomaly resolution.
• Guide and transition Automated Test Equipment from development to production, ensuring adequate fault coverage and solar array simulation capability for rate manufacturing.
• Manage and maintain full design documentation including schematics, PCB layouts, BOMs, drawings, and analysis reports within the PLM system.
• Manage and troubleshoot anomalies during vehicle integration and support flight acceptance testing.

Requirements

• Bachelor's degree in Electrical or Computer Engineering or related field with 7+ years of direct experience in electronics hardware development.
• Demonstrated design experience with solar array regulation topologies (shunt regulation, S3R, MPPT/PPT), spacecraft power bus architectures (regulated, unregulated, or semi-regulated), and high-voltage electronics (>50V).
• Experience with solar array electrical modeling, I-V curve characterization, and interface definition between solar array panels/strings and power regulation hardware.
• Experience designing to EMI/EMC requirements (MIL-STD-461 or equivalent) including conducted emissions, radiated emissions, and susceptibility.
• Experience designing fault-tolerant power electronics for high-reliability applications, including FMEA/FMECA participation and single-point failure elimination.
• Experience leading or significantly contributing to hardware qualification campaigns per MIL-STD-1540, SMC-S-016, ECSS-E-ST-10-03, or equivalent.
• Familiarity with eclipse/sun transition power management, battery charge integration, and interaction between SAR and downstream power management hardware.
• Strong understanding of electronics design and integration with mechanical systems for structural and thermal support, particularly for high-dissipation shunt elements.
• Experience using Altium (or similar tools) for schematic capture and layout.
• Experience using LTspice (or similar tools) for circuit simulations.
• Experience with Windchill PLM or equivalent configuration management systems.
• Experience with safety-critical systems development (automotive, aerospace, medical, etc.).
• Ability to work independently and as part of a team on rapid development programs.
• Excellent technical communication skills (written and verbal).

Qualifications

• Hands-on experience with the understanding of full product development lifecycle of electronics hardware.
• U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.

Skills

• Ability to work independently and as part of a team on rapid development programs.
• Excellent technical communication skills (written and verbal).

Benefits

• Medical, dental, vision, basic and supplemental life insurance.
• Paid parental leave.
• Short and long-term disability.
• 401(k) with a company match of up to 5%.
• Education Support Program.
• Stock Options for all regular employees (working at least 20 hours/week).
• Paid Time Off: Up to four (4) weeks per year based on weekly scheduled hours, and up to 14 company-paid holidays.
