Sound is an essential and compelling facet of the customer experience. Apple has assembled a world-class Acoustics team that enables our customers to experience music with delight, communicate with clarity and appreciate our products without disturbance from noise. In Apple Acoustics we work with obsessive attention to detail, directly contributing to products that ship to millions of people around the world.\nThe Audio System Tuning team is looking for an Acoustics DSP Engineer to ensure the correct marriage between audio software and acoustic hardware in Apple’s HW devices. The successful candidate will be responsible for all Audio DSP optimization for Voice Recognition applications in various iOS, MACOS and Wireless Apple products.\nDescription\nThe candidate will be a member of Acoustic Hardware Team, and work day-to-day with the Audio Tuning Engineers, DSP algorithm & ML teams. This role will require attention to details and excellent HW and SW debugging skills. You will be interacting with different teams at Apple regularly, and as such, you should have great communication and collaboration skills. You will tune, optimize and listen to different internally developed algorithms for Apple HW with focus on advanced techniques to deliver the best Voice Recognition experience across all Apple HW. This role might require some international traveling as well. Apple delivers world class products and Audio should just make these products even better with superb sound.\nMinimum Qualifications\nBS/MS or equivalent, preferably specializing in Audio or Electrical Engineering.\nSolid understanding of acoustics and signal processing fundamentals.\nExperience executing and debugging scripts with Python and MATLAB.\nFamiliarity with acoustic measurement equipment such HeadAcqua Test System, Soundcheck, and Audio Analyzers.\nPreferred Qualifications\nIn-depth Audio DSP knowledge for audio applications, such as Echo and Double Talk, Microphone Array Processing, Beam-Forming, Multi-Band Compression, Equalization, Noise Suppression in portable devices.\nExcellent coding and debugging skills (Python and C/C++ preferred).\nStrong background in applying Machine Learning methods and frameworks for Audio applications.\nExperience with tuning of echo cancellation algorithms, providing the correct tradeoff between echo return loss and double talk performance, and speech intelligibility.\nKnowledge on transducers and their Acoustic integration is preferred.\nOutstanding written and verbal communication skills, ability to work optimally in multi-functional teams.","description_format":"text","description_chars":2680,"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":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Operating Systems","Laptops","Smartwatches & Fitness Trackers","Tablets"],"lifecycle":[{"event":"open","at":"2026-10-24T01:42:34Z"}],"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":"2026-10-15T11:24:14+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":1,"expected_fill_days":102,"reasons":["conf:3","urgency","velocity","win:early","comp:brand"],"computed_at":"2026-10-25T05:49:26Z"},"pay":null,"html_url":"https://alion.io/job/apple-acoustics-dsp-engineer","json_url":"https://alion.io/job/apple-acoustics-dsp-engineer.json","meta":{"generated_at":"2026-10-25T15:58:17Z","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":22987,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-26T00:00:00Z"}},"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-acoustics-dsp-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%2Fapple-acoustics-dsp-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%2Fapple-acoustics-dsp-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/apple-acoustics-dsp-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fapple-acoustics-dsp-engineer"}]}
