If you are great at what you do, enjoy working in a startup environment, and are passionate about developing leading-edge electronics for satellites, spacecraft, and aerospace systems, we would like to hear from you.\nAt the Senior II level, you will be tasked with full-stack hardware development for complex modules and small systems. You will have the opportunity to start at concept development and progress through detailed design, analysis, layout, build, test, and delivery, doing hands-on work at each phase. The Senior II level also introduces technical leadership opportunities, gaining responsibility for small teams of hardware engineers developing new products and systems.\nAt a small company and a startup, your work will make direct contributions to the success of the business. The work is challenging and impactful, requiring both breadth and depth of technical knowledge. Our products are made for high-reliability space and airborne applications, so designs require high levels of technical rigor while maintaining the agility of a startup environment.\nThe successful candidate will also present engineering design review materials to our customers and executive team. As such, excellent written and verbal communication skills are required.\nSUMMARY OF RESPONSIBILITIES\nDesign and develop RF, mixed-signal, and digital hardware for electronically steered antenna (AESA) communication systems.\nSupport the adaptation of existing hardware designs for new customer platforms, operational environments, and regional requirements.\nDevelop RF front-end, power distribution, control, and interface circuitry for phased-array communication terminals.\nOwn the development of hardware modules and subsystems from requirements through schematic capture, layout, integration, verification, and production release.\nDevelop hardware requirements, perform trade studies, and support subsystem architecture development.\nPerform detailed schematic design for complex RF, mixed-signal, and high-speed digital circuit boards.\nSupport PCB layout activities in Altium Designer, including stack-up definition, component placement, routing reviews, and design-for-manufacturing considerations.\nPerform engineering analyses including worst-case circuit analysis, signal integrity, power integrity, thermal, and reliability assessments.\nDevelop and execute hardware bring-up, integration, debugging, and design verification activities.\nSupport RF characterization, system integration, troubleshooting, and root-cause investigations using laboratory test equipment.\nDefine and execute environmental, qualification, and compliance testing activities, including EMI/EMC verification.\nCollaborate closely with all the relevant engineering teams throughout the product lifecycle.\nSupport technical design reviews, engineering documentation, requirements traceability, and customer-facing technical activities.\nContribute to product qualification, certification, manufacturing transfer, and production support activities.\nProvide technical support for field trials, demonstrations, customer evaluations, and deployment activities.\nMentor junior engineers and technicians while promoting engineering best practices and technical rigor.\nApply knowledge of adjacent disciplines, including software, systems, RF, and mechanical engineering, to support efficient product development and integration.\nJOB REQUIREMENTS AND MINIMUM QUALIFICATIONS\nBachelor of Science (BS) degree or higher in Electrical Engineering from an accredited university.\nMinimum of 6 years of relevant experience in board-level electronics design, analysis, and test.\nDirect experience designing high-reliability electronics for space or defense applications, including part derating, worst-case analysis, and thermal constraints.\nExperience owning the design phase of complex board-level electronics, including trade studies, key part selection, and detailed design.\nExperience delivering hardware designs through production and deployment.\nExpertise in PCB layout, including high-density interconnect (HDI) stackup design and high-speed routing.\nExperience running board-level signal integrity and/or power integrity simulation tools such as Ansys SIwave, ADS SIPro, or Mentor Hyperlynx.\nStrong working knowledge of adjacent fields, such as software and mechanical, that guides hardware design and system design\nExpert-level proficiency in electronics design tools such as Altium.\nExtensive lab experience for bring-up and verification of new hardware.\nExcellent written and spoken communication skills.\nWHAT WE OFFER\nExperience leading small teams of hardware engineers to develop multi-module assemblies, including hardware architecture, requirements, make/buy decisions, and interconnects.\nDesign for space radiation
