The Cellular RF Systems Engineering team sits at the very core of that mission, defining the wireless technologies that enable seamless experiences for hundreds of millions of users worldwide.\nWe are looking for a motivated and dedicated engineer to join our team and contribute to our Cellular RF architectures. In this role, you will be at the center of RF innovation, helping to drive the evolution of our RF architecture by optimizing current systems, defining next-generation transceiver and front-end solutions and setting critical system requirements.\nDescription\nIn your role as the Cellular RF System Architect you will contribute and be part of an elite Cellular RF Systems Engineering Team. We are tasked with driving cellular radio technologies addressing GSM, UMTS, LTE, 5G NR and upcoming 6G standards. You will work closely with Platform Architecture, RFIC and PMU design teams, and suppliers to assess, scope, and ultimately drive Cellular RF technology innovation to meet the challenges of next generation wireless products. Occasional travel including international may be required.\nMinimum Qualifications\nBS and a minimum of 10 years relevant industry experience\nYou have experience in deriving implementation requirements based on high level system requirements.\nYou have strong analytical, interpersonal and communication skills with a proven ability to work across diverse, cross-functional teams to solve highly complex, multi-disciplinary problems.\nYou have strong Technical Writing Skills.\nPreferred Qualifications\nWe value your 5+ years of relevant experience in RF including direct expertise in transmitter and receiver architectures. You should never be satisfied with your knowledge so continuous study, research and collaboration is needed from you to grow.\nYou have in-depth knowledge of cellular radio standards (GSM, UMTS, LTE, 5GNR and upcoming 6G), regulatory, and carrier requirements including their implications on overall radio architectures and RF system design.\nYou have experience in RF performance criteria and concepts such as EIRP, TRP, noise figure, sensitivity/desense, phase noise, EVM, spectral mask, spurious, harmonics, intermodulation, s-parameters, Smith charts, and tuning networks.\nYou have experience in RF line-up analysis, AGC and TPC concepts, calibration and compensation methods.\nYou have experience in understanding complex system use cases and derive corresponding implementation requirements for optimum user experience.\nYou have understanding of antenna array theory and associated measurement methods.","description_format":"text","description_chars":2660,"description_truncated":false,"requirements":{"experience_years_min":10,"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":"2026-11-05T01:01:35Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 6,350 · green card filings: 37","filings_12m":6350,"filings_prev_12m":6527,"green_card_filings_12m":37,"median_offered_wage_usd":177355,"route":null,"cap_exempt":false,"checked_at":"2026-10-29T16:27:21+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)","US Department of Labor: PERM disclosure data (green cards)"],"filings_for_role_12m":1366}],"liveness":{"score":99,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.993,"p_room":1,"age_days":0,"expected_fill_days":128,"reasons":["conf:4","urgency","velocity","win:early","comp:brand"],"computed_at":"2026-11-05T05:54:30Z"},"pay":null,"html_url":"https://alion.io/job/apple-cellular-rf-system-architect-2","json_url":"https://alion.io/job/apple-cellular-rf-system-architect-2.json","meta":{"generated_at":"2026-11-05T07:47:56Z","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":9806,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-06T00:00:00Z"}},"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-cellular-rf-system-architect-2"},{"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-cellular-rf-system-architect-2"},{"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-cellular-rf-system-architect-2"},{"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-cellular-rf-system-architect-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fapple-cellular-rf-system-architect-2"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3781576}},{"tool":"search_jobs","arguments":{"company":"apple.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3781576},"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);
