The team is composed of experts with deep experience in microarchitecture, ISA definition, performance modeling, power modeling, and workload analysis. We are seeking a highly motivated, innovative, and confident individual to join the CPU Platform Architecture team to help drive advanced exploration for next-generation iPhone, iPad, Mac, and server CPU designs.\nDescription\nAs a CPU Performance Architect with a focus on the memory subsystem, you will be part of a team that is defining and optimizing CPU and cache micro-architecture. Working collaboratively, you will seek out areas of the design for improvement by identifying performance bottlenecks and evaluate ideas to address them. You will engage with experienced CPU and SoC designers in micro-architecture and RTL to assess the feasibility of ideas through modeling, refine ideas and model correlation, and seed new ideas. The role requires the analysis of single-threaded and multi-threaded workloads across existing and new product categories to identify bottlenecks and opportunities for improvement. We collaborate as a larger CPU architecture and performance team to maintain and improve the simulation environment to enable data-driven decisions and always look for ways to boost the productivity of the entire team.\nMinimum Qualifications\nBS degree\nExperience in CPU and SOC architecture and micro-architecture\nExperience with performance simulation environments\nObject-oriented programming experience in C/C++\nExperience in a scripting language such as Perl or Python\nPreferred Qualifications\nKnowledge of memory latency tolerance techniques or other aspects of CPU memory subsystem (i.e. prefetching, caching policies)\n20+ years of relevant industry experience\nMS or PhD in Electrical or Computer Engineering or Computer Science\nUnderstanding of common data structures and algorithms\nFamiliarity with SIMD, vector, or accelerator architectures\nFamiliarity with MP performance\nComfortable in an environment of uncertainty and able to navigate through ambiguities\nExperience in a research-driven environment","description_format":"text","description_chars":2270,"description_truncated":false,"requirements":{"experience_years_min":20,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Operating Systems","Laptops","Smartwatches & Fitness Trackers","Tablets"],"lifecycle":[{"event":"open","at":"2026-10-13T19:26:50Z"}],"visa":[{"country":"GB","licensed_sponsor":true,"evidence":"Licensed UK visa sponsor (Skilled Worker, Graduate Trainee, Senior or Specialist Worker)","filings_12m":null,"filings_prev_12m":null,"green_card_filings_12m":null,"median_offered_wage_usd":null,"route":"Skilled Worker; Global Business Mobility: Graduate Trainee; Global Business Mobility: Senior or Specialist Worker","cap_exempt":false,"checked_at":"2026-10-14T06:20:30+00:00","sources":["UK Home Office: register of licensed sponsors (workers)"],"filings_for_role_12m":0}],"liveness":{"score":60,"band":"ok","label":"Likely open","p_open":1,"p_active":0.602,"p_room":1,"age_days":0,"expected_fill_days":40,"reasons":["conf:3","stale_co","win:early","comp:brand"],"computed_at":"2026-10-14T06:34:16Z"},"pay":null,"html_url":"https://alion.io/job/apple-cpu-performance-architect-platform-architecture-4","json_url":"https://alion.io/job/apple-cpu-performance-architect-platform-architecture-4.json","meta":{"generated_at":"2026-10-15T02:07:01Z","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":3037,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-16T00:00:00Z"}},"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":12},"rest":"https://alion.io/mcp/rest/get_company?id=12"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fapple-cpu-performance-architect-platform-architecture-4"},{"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%2Fapple-cpu-performance-architect-platform-architecture-4"},{"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%2Fapple-cpu-performance-architect-platform-architecture-4"},{"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/apple-cpu-performance-architect-platform-architecture-4\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fapple-cpu-performance-architect-platform-architecture-4"}]}
