Senior Electrical Design Engineer

Besxar Space Industries, Inc. (Besxar) is building off-Earth foundries that use the natural ultra-high vacuum of space as a manufacturing input. Our Fabships are designed to produce trusted, ultra-high-yield semiconductor materials that are difficult or impossible to make on Earth at comparable purity and defect performance.

We are not building a science project; we are building a new industrial capability. That means real hardware, rapid iteration, disciplined execution, and a willingness to challenge assumptions from first principles as we design, fly, learn, and improve mission by mission.

Electrical engineering is central to Besxar’s ability to turn space into a factory floor. This role sits at the core of Fabship development: leading electrical engineering R&D, owning major ECAD assemblies, and translating ambiguous mission and business requirements into flight worthy electrical hardware and integration plans. You will help define how the electrical team operates as we scale.

You will work shoulder-to-shoulder with systems, mechanical, software, materials, manufacturing, and test to build flight hardware on real schedules. The expectation is hands-on leadership across architecture, schematic capture, PCB layout oversight, analysis, build, bring-up, integration, test, failure learning, and design iteration.

• Lead electrical design and R&D for Besxar Fabships, including architecture development, trade studies, detailed design, and integration strategy across power electronics, avionics, RF subsystems, instrumentation, DAQ, test interfaces, and supporting ground hardware.
• Directly own major ECAD assemblies and electrical product structure/BOM for critical systems; maintain strong configuration discipline, clear interfaces, robust libraries, and high-quality release packages for schematics, layouts, fabrication notes, assembly documentation, and released design data.
• Translate system requirements into manufacturable, testable, high-reliability electrical designs that balance performance, mass, power, thermal behavior, radiation tolerance, EMI/EMC, fault protection, serviceability, cost, and schedule.
• Drive the full hardware life cycle from blank-sheet concepting through component selection, schematic capture, PCB layout and layout direction/review, prototype builds, board bring-up, verification, qualification, vehicle integration, and flight or mission feedback.
• Design and analyze circuits and assemblies for high-power electronics, power conversion and distribution, mixed-signal interfaces, RF signal chains, spacecraft instrumentation, DAQ systems, and diverse sensor/actuator interfaces using space-rated and radiation-tolerant or rad-hard components where appropriate.
• Lead hands-on assembly, lab bring-up, and integration of PCBAs, harnesses, enclosures, and test setups.
• Create or review board bring-up test plans and procedures, work instructions, and associated documentation, along with higher level test-plans, functional test procedures, assembly work-instructions and procedures, and environmental test-limit definitions.
• Lead development of post-launch inspection criteria, checkout flows, and test plans needed for repeated flight operations.
• Develop HITL and bench test capabilities to validate subsystem behavior, characterize performance, close requirements, and accelerate debugging across development and integration.
• Perform and review electrical analyses needed to close designs with appropriate engineering margin, including worst-case and derating analysis, grounding and isolation, EMI/EMC, radiation and environmental considerations, and failure modes and risk assessments.
• Bring a strong lessons-learned mindset: use prior design experience, integration results, supplier issues, operational unit behavior during environmental test and on-orbit operation, and failure investigations to improve each hardware revision and avoid repeating mistakes.
• Partner with technicians, manufacturing, supply chain, and external vendors to move assemblies from design through fabrication, inspection, PCBA assembly, rework, verification, integration, and environmental test.
• Lead or contribute to design reviews,…
