Senior Electrical Design Engineer

About this role

<p><strong>About Us</strong></p> <p>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.</p> <p>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.</p> <p><strong>About the Team</strong></p> <p>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 flightworthy electrical hardware and integration plans. You will help define how the electrical team operates as we scale.</p> <p>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.</p> <p><strong>Roles & Responsibilities</strong></p> <ul> <li>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.</li> <li>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.</li> <li>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.</li> <li>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.</li> <li>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.</li> <li>Lead hands-on assembly, lab bring-up, and integration of PCBAs, harnesses, enclosures, and test setups.</li> <li>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. </li> <li>Lead development of post-launch inspection criteria, checkout flows, and test plans needed for repeated flight operations. </li> <li>Develop HITL and bench test capabilities to validate subsystem behavior, characterize performance, close requirements, and accelerate debugging across development and integration.</li> <li>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.</li> <li>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.</li> <li>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.</li> <li>Lead or contribute to design reviews, root-cause investigations, anomaly resolution, and configuration changes with a high bar for clear communication and sound engineering judgment.</li> <li>Help define how electrical engineering is done at Besxar, including ECAD conventions, library management, design checklists, release processes, test standards, and cross-functional review norms.</li> <li>Mentor other engineers and contribute technical leadership as the electrical team grows.</li> </ul> <p><strong>Basic Qualifications</strong></p> <ul> <li>Bachelor's degree in Electrical Engineering, Computer Engineering, Physics, or a similar technical discipline, or equivalent practical experience.</li> <li>8+ years of progressive electrical design engineering experience developing complex hardware products from concept through build, integration, and test.</li> <li>Demonstrated ownership of large ECAD assemblies and electrical product development for highly integrated spacecraft, aerospace, defense, semiconductor/process equipment, or other high failure-consequence systems.</li> <li>Strong proficiency in a modern ECAD platform (e.g., Altium Designer, Cadence…
