  • Description:
  • As part of a small, passionate, and accomplished advanced concepts team, you will contribute to the design of Electrical Power Systems for the Blue Moon lander, which includes power generation, storage, regulation, and distribution to vehicle subsystems and payloads. This position will directly impact the history of space exploration, and your dedicated commitment and detailed attention will further the cause of safe and repeatable spaceflight.
  • Responsibilities:
  • Maintain Electrical Power System (EPS) budgets that track power generation, consumption and storage during all relevant portions of a mission.
  • Conduct trades studies and contribute knowledge to help down-select electrical power system architectures appropriate for mission requirements.
  • Methodically estimate power consumption and account for margin of EPS components based on a combination of first principals, empirical information, and test data.
  • Create and maintain drawings and diagrams for power distribution, system grounding, and bonding.
  • Create models and simulation of the EPS to evaluate use cases and conditions.
  • Perform analyses such as voltage drop/line loss, component derating/stress analysis, and worst-case analysis.
  • Trade combinations of various power generation and storage solutions such as solar arrays, fuel cells, and battery modules (especially Li-Ion chemistries).
  • Specify and select power distribution, conversion, and control components. For example, centralized vs. point-of-load voltage conversion.
  • Estimate the size, weight, and location on vehicle of EPS components.
  • Effectively communicate development status, risks, and challenges to management.
  • Work closely with systems and design engineers to develop integrated design solutions, rapidly assess conceptual designs.
  • Select component supplier options based on technical capabilities that match program objectives.
  • Generate specifications and drawings that can be used to procure EPS component hardware.
  • Write cogent and succinct technical memos and devise innovative, intuitive, and delightful ways to visualize quantitative information.
  • Qualifications:
  • Minimum of a B.S. degree in Electrical, Mechatronics, or Aerospace Engineering or equivalent
  • 7+ years industry experience in electrical power system design and analysis
  • Engineering software experience in power simulation and analysis tools (SPICE, MATLAB, Simulink, Simscape, etc.)
  • Experience with high voltage space power systems
  • Experience with a scripting language or platform such as MATLAB or Python
  • Experience working collaboratively in small teams on fast-paced projects
  • Exhibit excellent judgement and be comfortable making high-quality and high-velocity decisions
  • Must be a 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.
  • Desired
  • M.S. in Electrical, Mechatronics, or Aerospace Engineering
  • Experience with electromagnetic interference and compatibility a plus, especially in the space environment
  • Experience in deep space radiation environmental compatibility and verification
  • Familiarity with version control, preferably Git.
  • Experience with collaboration tools such as Confluence and JIRA
  • Experience in low and high voltage wiring harness specification and design
  • Familiarity with embedded control techniques, executable code generation, and specification of controller communication protocols
