This role focuses on partitioning and structuring power domains within complex processor subsystems, with a strong emphasis on the aggressive duty cycling, ultra-low standby power, and constrained energy budgets inherent to satellite IoT end-node devices.\nKey Responsibilities:\n· Define and architect power domains within processor subsystems, including always-on, switchable, and retention domains optimized for low-power use cases\n· Design and implement power domain partitioning strategies for subsystems involving embedded processors, bus interconnects, and associated peripherals\n· Develop and integrate supporting logic for power domain separation, including power switches, isolation cells, level shifters, and retention registers\n· Define and implement power control sequencing and state machines for domain power-up/power-down flows, with emphasis on fast wake-up latency requirements for satellite link windows\n· Collaborate with SoC architects, physical design, and verification teams to ensure power domain intent is correctly captured in UPF\n· Drive definition of low-power modes (e.g., Sleep, Deep Sleep, Power-Off) and their interaction with system-level power management in battery- or energy-harvesting-powered IoT devices\n· Work with processor subsystem reference designs as a baseline and adapt the power architecture to the unique demands of satellite IoT SoCs\n· Support power-aware synthesis, place-and-route, and sign-off flows in coordination with the physical design team\n· Define and review power intent files (UPF/IEEE 1801) and ensure consistency with RTL implementation\n· Engage with verification teams to ensure power domain structures are properly tested and validated across all low-power operating modes\nRequired Qualifications:\n· Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, or related field\n· 7+ years of experience in ASIC/SoC design with a strong focus on low-power architecture\n· Deep hands-on experience with power domain definition, isolation strategies, and retention architectures\n· Proficiency with UPF (IEEE 1801) power intent format\n· Strong knowledge of RTL design using SystemVerilog or VHDL\n· Demonstrated experience optimizing for ultra-low power consumption in energy-constrained applications such as IoT, wearables, or similar\n· Familiarity with low-power synthesis and physical design constraints\nPreferred Qualifications:\n· Experience with Arm Corstone or similar processor subsystem IP, including Arm processor subsystems (Cortex-M series) or similar embedded processor architectures\n· Knowledge of AMBA bus protocols (AHB, APB, AXI) as they relate to power domain crossings\n· Experience with power analysis tools (e.g., Synopsys PrimeTime PX, Cadence Joules)\n· Understanding of battery-powered and energy-harvesting device constraints as they influence SoC power architecture decisions\n· Familiarity with power management ICs (PMICs) and their interface to domain control logic\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":3343,"description_truncated":false,"requirements":{"experience_years_min":7,"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":["Incident Response","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":161,"expected_fill_days":52,"reasons":["conf:0","stale_co","velocity","ghost","win:tail","crowd:brand"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/espace-soc-power-architecture-engineer-processor-subsystem","json_url":"https://alion.io/job/espace-soc-power-architecture-engineer-processor-subsystem.json","meta":{"generated_at":"2026-10-17T09:40:40Z","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":12708,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"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-soc-power-architecture-engineer-processor-subsystem"},{"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-soc-power-architecture-engineer-processor-subsystem"},{"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-soc-power-architecture-engineer-processor-subsystem"},{"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-soc-power-architecture-engineer-processor-subsystem\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fespace-soc-power-architecture-engineer-processor-subsystem"}]}
