Sr. EMC Engineer

Astrolab is The Lunar Operations Company. We design and build the systems and hardware the lunar economy will come to depend on — rovers, power, and data networks for sustained operations on the Moon. We are focused on the problems that must be solved before the next chapter of human exploration can scale. The Moon does not forgive untested assumptions. The people who work here know that, and they wouldn't have it any other way. As an EMC Engineer, you will be responsible for ensuring Avionics components are designed to endure the harsh electromagnetic environmental effects of interplanetary space. You will play a pivotal role in defining the design criteria for state-of-the-art avionics and electro-mechanical systems for the lunar surface with a strong focus on electromagnetic compatibility, in-space charging effects, and interdisciplinary requirements. You will be joining a company at the ground-level and have immense influence over the future of lunar exploration. What you'll do: Collaborate closely within cross-functional Engineering teams to capture requirements, lead design trades with respect to EMI/EMC, and integrate the design into the rover systems Contribute to full avionics and electro-mechanical systems/subsystems from system to component level with specific focus on E3 design criteria and operational/survivability requirements Analyze and contribute to designs relating to the effects of circuit and power system grounding architectures, structural electrical bonding, circuit isolation, shielding effectiveness, radiated/conducted emissions and susceptibility, near field/far field electromagnetics, transient protection, signal and power integrity, and general RF compatibility Troubleshoot EMI issues from board to system level Operate and automate a variety of EMI, RF, and electronics test equipment (spectrum analyzers, network analyzers, signal generation, oscilloscopes) within the context of avionics development and in house EMC testing Create and update technical documentation including command media, system diagrams, schematics, interface control documents, procedures, work and/or build orders, vendor and payload requirements, and test/anomaly reports Support flight hardware component qualification and spacecraft integration testing, including production issue dispositions, troubleshooting failures, and managing overall spacecraft risk What you'll bring: Basic Qualifications Bachelor's degree in a science, technology, engineering, mathematics (STEM) related field 5+ years of experience in EMI/EMC requirements, analysis, design, and testing for spacecraft systems and/or avionics component design (academic and personal projects apply) Experience with Analytics/Modeling/Simulation tools such as LTSpice, and experience with electrical circuit analysis using simulation tools such as Spice or equivalent Preferred Qualifications Experience with lab equipment such as oscilloscopes, multimeters, signal generators, logic analyzers, etc. Familiarity with SMC-S-016 testing requirements, and testing per SMC-S-016 Knowledge of electrical safety and EMC commercial compliance standards and/or testing MIL-STD-461 experience across the full range of EMC test (radiated susceptibility, radiated emissions, conducted susceptibility, conducted emissions) standards Experience in high power avionics system designs for spacecraft including: LDO Regulators, Buck/Boost converters, power line filters and various spacecraft grounding schemes for high voltage systems Experience in motor controller system designs for brushless DC motors (BLDC) and permanent magnet synchronous motors (PMSM) in both low and high voltage systems Ability to read, interpret and follow circuit schematics, PCB layouts, engineering drawings, BOMs, cable harnesses, wiring schematics, interface diagrams, layout drawings, mechanical drawings, and CAD software Benefits and Perks Join a team of best-in-class engineers building the foundation of planetary surface exploration Equity ownership in the company Comprehensive health benefits, including medical, dental, vision, and mental health support 401(k) plan with company match Flexible PTO and parental leave Weekly lunch stipend, plus complimentary snacks and beverages on-site Once a month social hour on-site with food and drinks
