If you enjoy working in a startup environment, and are passionate about developing leading-edge hardware for satellites, spacecraft, and aerospace systems, we would like to hear from you.\nIn this position, you will be responsible for the mechanical design of CesiumAstro products through all phases of the development process. The ideal candidate will have extensive experience in electronics packaging design, mechanical simulations and analyses, computer-aided design (CAD), spacecraft mechanical interfaces, and environmental qualification of electronic assemblies.\nAs a staff mechanical team member, you will be responsible for mechanical designs from initial concept design through requirements definition, detailed design, simulation, analysis, manufacturing, testing, qualification, and in-orbit support of CesiumAstro's products. Required skills and experience include thermal management design, precision machining principles, thermal simulation and analysis, shock and vibration simulation and analysis, electromagnetic interference/compatibility (EMI/EMC) mitigation techniques, geometric dimensioning and tolerancing (GD&T), finite element analysis (FEA), and cost analysis to develop, validate, and optimize mechanical designs. Principal engineers also serve as technical and professional mentors in their field.\nThe successful candidate will also present engineering design review materials to our customers and executive team, as well as participate in proposal-writing efforts. As such, excellent written and verbal communication skills are required.\nJOB REQUIREMENTS AND MINIMUM QUALIFICATIONS\nA Bachelor of Science (BS) or Master of Science (MS) degree in Mechanical or Aerospace Engineering from an accredited university or institution.\n8 years of industry experience in design and analysis of electronics packaging, including thermal, vibration, and stress dynamics.\nDemonstrated expertise in packaging high-power and high-density electronic assemblies.\nStrong understanding of thermal management techniques for spaceborne and/or high-power electronics. \nExperience designing hardware for launch and spaceflight environments (or similar). \nExpertise in finite element analysis and thermal simulation tools (Ansys or similar).\nExpert-level proficiency with professional mechanical CAD tools (SolidWorks or similar).\nExperience with precision machining, advanced manufacturing processes, and tolerance analysis. \nExperience with EMI/EMC mitigation techniques.\nStrong understanding of GD&T and aerospace drawing practices. \nExcellent written and verbal communication skills.\nPREFERRED EXPERIENCE\nExperience packaging digital, power or RF printed circuit board assemblies. \nExperience with spacecraft payloads, avionics, or power systems. \nKnowledge of NASA, DoD, ESA, or commercial space qualification standards. \nExperience with thermal vacuum testing and spacecraft environmental qualification. \nFamiliarity with materials selection for radiation and outgassing environments.","description_format":"text","description_chars":3057,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Embedded
