We are the pioneers of commercial space, leading the transformation of low-Earth orbit into a global space marketplace. Our mission-driven team is seeking a bold and dynamic Electrical Design Engineer, Senior who is fueled by high accountability, execution horsepower, and driven to understand our world, science/technology, and life itself, for the benefit of all on Earth and beyond. POSITION SUMMARY Since Axiom Space is a very complex work environment, we are looking for a resilient, high-energy Electrical Design Engineer, Senior to own the design and development of electrical and electronics components for the Axiom Extravehicular Mobility Unit (AxEMU) Portable Life Support System (PLSS). The AxEMU PLSS contains flight computers, radios, sensors, and network switches that enable communication and control during all aspects of a spacewalk. You will be responsible for creating the electrical and electronic components that manage commands, telemetry, and internal data flows, ensuring the suit operates reliably and meets mission objectives. Technical scope grows around that core as you learn the program: interface data checks, PCB card design, test readiness, supplier data intake, and review package preparation. KEY DUTIES & RESPONSIBILITIES - Conceptualization, design, development, testing, and integration of electrical systems. - Select and trade avionics architectures to balance performance, power, mass, cost, and reliability - Ensure designs meet radiation hardness, reliability, and resilience standards for space environments. - Lead requirements definition and develop Interface Control Documents (ICDs) for integration with other spacecraft systems. - Integrate with other vehicle and test functions including thermal control, flight software, power distribution, test facilities, and test support equipment. - Specify functional, performance, and environmental requirements for electrical systems. - Document design decisions, trade studies, and verification plans. - Provide technical oversight during integration, system-level testing, and acceptance testing. - Resolve technical issues and ensure the electrical systems meet all mission-critical performance goals. - Lead vendor selection and make/buy decisions, balancing technical risk, schedule, cost, and lifecycle support. - Evaluate commercial-off-the-shelf (COTS) components for suitability and reuse potential. - Communicate progress, status, and issues honestly and early, including when something is not working. - Perform additional job duties as assigned. QUALIFICATIONS: To perform this job successfully, an individual must be able to perform each essential duty satisfactorily. The requirements listed below are representative of the knowledge, skill, and/or ability required. Reasonable accommodations may be made to enable individuals with disabilities to perform the essential functions. Education & Experience - Bachelor's degree from an accredited college or university in Electrical Engineering, Computer Engineering, or equivalent. - Level 3: 5 or more years’ experience in circuit and PCB design. An equivalent combination of education and experience may be considered. - Experience with the design, analysis, and integration of spacecraft avionics, embedded systems, and data handling protocols. - Experience working in a lab setting and proficiency working oscilloscopes, multimeters, spectrum analyzers, VNAs, and related lab equipment. - Experience using EDA software such as Altium Designer. - Working knowledge of I2C, SPI, SpaceWire, Ethernet, RS422/485, UART, USB, and similar spacecraft communications protocols. - Experience implementing ADCs and analog sensing circuits such as radiometric, 4-20mA, and related. - Experience with high-speed and mixed-signal digital designs. - Familiar with IPC standards for board design; preference for experience designing IPC class 2 and 3 PCBs. - Experience with product life cycle and having worked on designs from concept through production. - Vehicle integration experience is a plus. - Has experience supporting EMI/EMC and other validation tests. - Experience designing and routing controlled-impedance and controlled-length signals. - Clear technical writing, and the ability to produce verification documentation, status material, and review packages that other people can act on. - Curiosity, initiative, and the willingness to ask a question early rather than deliver a wrong answer late. - Comfort working in an ambiguous, fast-moving environment where the answer is often not yet written down. Preferred Qualifications - Experience in integration and test in spacecraft, aerospace, defense, or other high reliability programs. - Familiarity with interface control documents, requirements management tools such as Jama or DOORS, or configuration management practice. - Exposure to laboratory or test operations, including equipment procurement, facility readiness, or test scheduling. - Familiarity with industry or space program standards such as NASA SSRI, IEEE-ISTO-MOSA-IF-S-001, MIL-STD-1553, NASA-STD-7002, or NASA-STD-3001. - Engineer in Training certification, or progress toward professional certification. Core Skills - Passion for space and the mission - Entrepreneurial, growth mindset - High EQ and ability to collaborate within teams and cross-functionally - Tech-solutioning in using systems and tools to move smarter and faster Core Competencies: Embody our core values of leadership, innovation, and teamwork. In addition, to perform the job successfully, an individual should demonstrate the following competencies: - Accountability - Technical Rigor - Execution Discipline - Pride of Delivery WORK ENVIRONMENT: Generally, an office environment, but can involve inside or outside work depending on the task. Requirements - This position may require access to export controlled technical data or technology subject to NASA regulations, International Traffic in Arms Regulations (ITAR), or Export Administration Regulations (EAR). In accordance with U.S. export control laws, final candidates may be required to undergo additional export control screening to determine eligibility for access. Meeting these requirements is a condition of employment. - Management has the prerogative to select at any level for which the position is advertised - Must be willing to work evenings and weekends as needed to meet critical project milestones Physical Requirements - Work may involve sitting or standing for extended periods (90% of the time) - May require lifting and carrying up to 25 lbs. (5% of the time) - Equipment and Machines - Standard office equipment (PC, phone, printer, etc. Axiom Space is proud to be an equal opportunity employer.
