Join our team of experienced SW engineers and debuggers in validating Apple's world class silicon. In this highly visible role you will be writing functional validation SW for the CPUs, caches, and memory subsystem of our SoCs, with the aim of identifying logic design and circuit bugs. You will be a SW developer for a system validation tool used widely across Apple's Silicon Engineering group, and will collaborate with SoC design and product engineering teams to debug and drive silicon issues to root-cause.\nDescription\nWork with designers and architects to understand the functionality of various blocks in the SoC\nCreate validation test plans, ensuring all key features are covered\nDevelop SW workloads to validate various CPU and memory subsystem features - Integration of these workloads into an existing system validation tool\nMake enhancements to the tool's SW framework to support new CPU architectures\nDrive the bring-up and execution of our validation SW in pre-silicon (FPGAs) and post-silicon (development boards)\nDebug workload failures using a variety of tools and hooks\nRelease and distribute our system validation SW to cross-functional teams across Apple\nMinimum Qualifications\nExperienced C and assembly programmer.\nExperience with scripting languages such as Python, Perl, or Tcl\nKnowledge of software tool chains including including compilers, assemblers, and source control tools\nExperience with GenAI tools (like Claude code)\nAbility to work well in a team, but to be responsible and self-driven\nStrong understanding of micro-processor architecture - a plus\nGood knowledge of ARM or another CPU instruction set architecture - a plus\nFamiliarity with memory technologies and power management - a plus\nBackground in silicon bring-up and debug experience - a plus\nPreferred Qualifications\nA minimum of a BS degree and a minimum of 3 years of relevant industry experience in silicon validation software engineering or related field.","description_format":"text","description_chars":2051,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Operating Systems","Laptops","Smartwatches & Fitness Trackers","Tablets"],"lifecycle":[{"event":"open","at":"2026-11-12T23:26:24Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":148,"reasons":["conf:2","win:early","comp:brand"],"computed_at":"2026-11-13T02:12:00Z"},"pay":null,"html_url":"https://alion.io/job/apple-silicon-validation-software-engineer-cpu-and-memory-hierarchy-5","json_url":"https://alion.io/job/apple-silicon-validation-software-engineer-cpu-and-memory-hierarchy-5.json","meta":{"generated_at":"2026-11-13T02:12:00Z","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":4587,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-14T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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-silicon-validation-software-engineer-cpu-and-memory-hierarchy-5"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"free","price":{"credits":0,"usd":0},"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-silicon-validation-software-engineer-cpu-and-memory-hierarchy-5"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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-silicon-validation-software-engineer-cpu-and-memory-hierarchy-5"},{"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-silicon-validation-software-engineer-cpu-and-memory-hierarchy-5\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fapple-silicon-validation-software-engineer-cpu-and-memory-hierarchy-5"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4205294}},{"tool":"search_jobs","arguments":{"company":"apple.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4205294},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
