Today everything we use in orbit - fuel, water, materials - is launched from Earth, which keeps every mission slow, expensive and small. Asteroids already hold those resources in orbit. We build the spacecraft and systems to go get them.\nOur first mission launches in 2028 to rendezvous with the asteroid Apophis - a deep-space mission designed, built and tested by our team in Broomfield, Colorado, on a startup timeline and budget. We develop most of our own hardware, from power and propulsion electronics to RF systems and payloads, and we test it in our own facilities.\nThe role\nYou will own the spacecraft’s electrical backbone: an ~8 kW solar array feeding a high-voltage bus that drives electric propulsion, a low-voltage bus that runs everything else, and the power conditioning, battery management and distribution hardware in between. Most of it is designed here. You’ll be responsible for making it work as a system - from the array’s peak-power tracking through the HV bus to the PPU, down through the HV-to-LV conversion to the 28 V loads.\nRequirements\nDay to day you will\nOwn the power architecture and budget end to end: array, peak-power tracking, HV bus, battery and charge/discharge regulation, HV-LV conversion, and distribution - and keep the budgets closed as the spacecraft evolves.\nDesign the array-to-bus interface: MPPT strategy, string configuration, and the behaviour of an unregulated HV bus feeding a 5 kW electric-propulsion load as the array degrades through the Van Allen belts and the vehicle flies power-limited.\nSet and defend the bus specification against the loads: PPU input range, inrush and ripple at thruster ignition, bus stability at the PCDU-PPU interface, and the cold-eclipse-exit overvoltage case that sets the HV design point.\nLead the PCDU and power electronics development with the avionics team across board-level design, power switching and protection, telemetry, and the fault-protection behaviour that lets the vehicle recover on its own at 150 million kilometres.\nBuild the power flatsat with an array simulator and a propulsion load simulator, and carry the subsystem through integration, EMC and environmental qualification in our own facilities.\nYou'll fit if you have\nDelivered a spacecraft power subsystem, or a major part of one, through test - including hands-on power-electronics design, not only architecture.\nStrong fundamentals in DC power conversion, control-loop and bus-stability analysis, battery systems and solar-array electrical behaviour across temperature and radiation.\nExperience with high-voltage spacecraft buses or high-power EP interfaces; GEO electric orbit-raising background is directly relevant.\nWorking knowledge of radiation effects and derating practice for power parts.\nThe habit of owning the whole thing: requirements, design, suppliers, test and documentation.\nComfort with a small team where you’ll make the calls.d hand to a committee.\nNice to have\nMPPT/direct-drive array architecture\nPCDU/EPS board design for flight\nEMC test experience\nFamiliarity with F Prime or similar flight software frameworks for telemetry and fault protection\nRequired\nUS work authorization\nBenefits\nSalary Range: $150k-200k annually\nBenefits:\nMedical plans\nDental & Vision plans\nLife insurance\nShort-term and Long-term Disability Insurance\n401(k) Retirement Plan\nEquity Incentive Plan","description_format":"text","description_chars":3434,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity","Life insurance","Retirement plans"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Electrical & Electronic Engineering","Satellite Manufacturing","Earth Observation"],"lifecycle":[{"event":"open","at":"2026-10-20T00:03:49Z"}],"visa":[],"liveness":{"score":79,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.788,"p_room":1,"age_days":8,"expected_fill_days":30,"reasons":["conf:1","win:early"],"computed_at":"2026-10-27T05:46:45Z"},"pay":{"stated_usd_annual":200000,"is_top_pay":true},"html_url":"https://alion.io/job/karman-power-systems-engineer","json_url":"https://alion.io/job/karman-power-systems-engineer.json","meta":{"generated_at":"2026-10-27T11:47:00Z","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":13969,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-28T00:00:00Z"}},"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":2335634},"rest":"https://alion.io/mcp/rest/get_company?id=2335634"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fkarman-power-systems-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%2Fkarman-power-systems-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%2Fkarman-power-systems-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/karman-power-systems-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fkarman-power-systems-engineer"}]}
