Beginning with Axiom Station, successor to the International Space Station, the company is pioneering a next-generation orbital settlement that will foster groundbreaking innovation and research in microgravity and drive the global space economy of tomorrow. Today, guided by the vision of leading humanity's expansion off planet, Axiom Space is the principal provider of commercial human spaceflight services and developer of advanced spacesuits for the Moon and beyond. For more information about Axiom Space, visit www.axiomspace.com.\nAxiom Space fosters a work environment inclusive of all perspectives. 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 Power System 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.\nPOSITION SUMMARY\nSince Axiom Space is a very complex work environment, we are looking for a resilient, high-energy early career Electrical Power System Engineer (up to a level III) who already knows what a converter does and why a control loop can be unstable, and who wants to learn the rest on a program that is building real flight hardware for a commercial space station. You will own real work, with a senior engineer reviewing it, and the scope of what you own will grow as fast as you can carry it.\nThe Axiom Space Station power architecture is a regulated 120 V dual bus system: solar array regulation as the first bus forming stage, isolated conversion as the second, high voltage energy storage with charge and discharge regulation, secondary conversion to 120 V and 28 V, and protected load distribution through latching current limiters, all of it distributed across module boundaries and across berthing and docking interfaces. You will work inside that architecture on requirements, analysis, interface definition, supplier data, and test.\nKEY DUTIES & RESPONSIBILITIES\nDraft and maintain electrical power requirements under the direction of a senior engineer, including verification methods and traceability in the program requirements management tool, and track TBD and open item closure.\nBuild and run system models and analyses: power and energy budgets, load lists and load profiles, voltage drop and harness sizing, fault current and protection sizing calculations, efficiency and dissipation rollups, and basic transient studies.\nSupport the development of interface control documents and power quality documentation, including data collection, table construction, consistency checking, and reconciliation of numbers across documents.\nMaintain the configuration data that the system runs on: equipment master lists, load databases, connector and harness data, and the version and change history behind them.\nSupport supplier technical exchanges: prepare question sets, track answers and actions, review supplier data packages against the specification, and flag inconsistencies.\nSupport laboratory and engineering model testing: test setup, instrumentation, execution support, data reduction, and test report drafting.\nPrepare material for SRR, PDR, CDR, Test Readiness Review, and Manufacturing Readiness Review, and support action closure.\nGrow toward ownership of a requirement set, an analysis area, and an interface, with mentorship from senior team members.\nCommunicate progress, status, and issues honestly and early, including when something is not working.\nPerform additional job duties as assigned.\nQUALIFICATIONS:\nTo 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.\nEducation & Experience\nBachelor's degree from an accredited college or university in Electrical Engineering or equivalent.\nLevel 2: 2 or more years of relevant experience, which may include internship, co-op, or research experience.\nLevel 3: 5 or more years of relevant experience. An equivalent combination of education and experience may be considered.\nWorking knowledge of power electronics fundamentals: isolated and non-isolated DC to DC conversion, basic control loop and stability concepts, magnetics, and protection devices.\nAbility to build and run engineering calculations and models in MATLAB and Simulink, Python, Excel, or equivalent, and to explain the assumptions behind them.\nLaboratory competence with oscilloscopes, multimeters, electronic loads, programmable power supplies, and data acquisition.\nClear technical writing. You will write documents that external organizations read, and the ability to write a precise sentence matters as much here as the ability to run a simulation.\nCuriosity, initiative, and the willingness to ask a question early rather than deliver a wrong answer late.\nComfort working in an ambiguous, fast-moving environment where the answer is often not yet written down.\nPreferred Qualifications\nInternship, co-op, or project experience in spacecraft, aerospace, defense, or other high reliability power systems.\nHands on converter design, build, or test experience, including academic projects and competition teams.\nExposure to requirements management tools such as Jama or DOORS, and to formal verification practice.\nExposure to space power standards and practices, including SSP 30237, SSP 52051, or NASA-STD-4003.\nExposure to EMC testing, grounding and bonding practice, or environmental test campaigns.\nEngineer in Training certification, or progress toward professional licensure.\nCore Skills\n· Passion for space and the mission\n· Entrepreneurial, growth mindset\n· High EQ and ability to collaborate within teams and cross-functionally\n· Tech-solutioning in using systems and tools to move smarter and faster\nCore Competencies:\nEmbody our core values of leadership, innovation, and teamwork. In addition, to perform the job successfully, an individual should demonstrate the following competencies:\n· Accountability\n· Technical Rigor\n· Execution Discipline\n· Pride of Delivery\nWORK ENVIRONMENT:\nGenerally, an office environment, but can involve inside or outside work depending on the task.\nRequirements\nThis 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.\nManagement has the prerogative to select at any level for which the position is advertised\nMust be willing to work evenings and weekends as needed to meet critical project milestones\nPhysical Requirements\nWork may involve sitting or standing for extended periods (90% of the time)\nMay require lifting and carrying up to 25 lbs. (5% of the time)\nEquipment and Machines\nStandard office equipment (PC, phone, printer, etc.)\nAxiom Space is proud to be an equal opportunity employer.
