You will be responsible for power distribution, battery management, charge regulation, and power conditioning circuits across multiple avionics boards. The role demands deep analog and power design expertise, combined with the rigor required for space-grade hardware.\nKey Responsibilities:\nDesign DC/DC converter power stages including switching device selection, filter design, driver circuits, and magnetics.\nDevelop battery management and charge regulation circuits with appropriate safety, cycle-life, and charging-profile considerations.\nPerform control-loop modeling and compensation for analog and digitally controlled power supplies.\nDesign fault-protection circuits including overcurrent break, current clamp, overvoltage clamp, crowbar, and foldback protection.\nImplement current, voltage, and temperature sensing circuits with filtering, threshold triggers, and ADC integration.\nPerform component derating analysis and design for radiation tolerance across all power subsystems.\nDevelop load accounting, mode-based power consumption estimates, and concept-of-operations power budgets.\nDesign power distribution networks with DC load switches, telemetry, and protection for multiple subsystem loads.\nCollaborate with PCB layout engineers on power supply layout optimization (loop area minimization, noise reduction, switching node management).\nSupport FPGA and digital teams with power supply sequencing, support circuitry, and power integrity requirements.\nRequired Qualifications:\nBachelor’s or Master’s degree in Electrical Engineering or related field.\n5+ years of experience in power electronics design for aerospace, defense, or high-reliability systems.\nProven experience designing DC/DC converters, LDOs, and power distribution systems.\nStrong understanding of control-loop theory (analog and digital compensation, stability analysis).\nExperience with fault protection design and safe operating area analysis.\nProficiency with circuit simulation tools (SPICE, LTSpice, or equivalent).\nKnowledge of component derating standards and radiation tolerance considerations for space applications.\nPreferred Qualifications:\nExperience with satellite or spacecraft power subsystems (PDU, BMS, BCR, solar array interfaces).\nBackground in lithium-ion battery performance, safety, and packaging considerations.\nExperience with motor-drive design and inductive-load drivers (solenoids, magnetorquers).\nFamiliarity with orbit-geometry analysis for power-balance and eclipse-cycle planning.\nUnderstanding of solar panel I-V characteristics, harvesting topologies, and degradation modeling.\nSupply-chain awareness including long-lead component identification and pre-buy strategies.\nTools & Technologies:\nSPICE-based circuit simulation (LTSpice, PSpice, or equivalent)\nAltium Designer (schematic capture)\nHyperLynx PI (power integrity analysis)\nMATLAB or Python for control-loop modeling and power budget analysis\nAdditional Requirements\nThis is a fast-paced, high-impact environment - flexibility to occasionally work extended hours or weekends during critical periods is expected.","description_format":"text","description_chars":3213,"description_truncated":false,"requirements":{"experience_years_min":5,"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":["Electrical & Electronic Engineering","Space & Aerospace","Satellite Manufacturing"],"lifecycle":[{"event":"open","at":"2026-09-01T08:47:55Z"},{"event":"reopen","at":"2026-10-14T07:11:13Z"}],"visa":[],"liveness":{"score":8,"band":"cold","label":"Long shot","p_open":1,"p_active":0.3,"p_room":0.28,"age_days":203,"expected_fill_days":61,"reasons":["conf:3","velocity","ghost","win:tail","crowd:brand"],"computed_at":"2026-10-23T05:54:15Z"},"pay":{"stated_usd_annual":250000,"is_top_pay":true},"html_url":"https://alion.io/job/espace-power-electronics-engineer","json_url":"https://alion.io/job/espace-power-electronics-engineer.json","meta":{"generated_at":"2026-10-24T04:20:54Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":6826,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-25T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":2438005},"rest":"https://alion.io/mcp/rest/get_company?id=2438005"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fespace-power-electronics-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fespace-power-electronics-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fespace-power-electronics-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/espace-power-electronics-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fespace-power-electronics-engineer"}]}
