We're looking for an experienced software engineer to help build and scale a performance testing platform used across the org - one that gives developers confidence that results measured in a dev environment reflect what will happen in production. You'll work closely with product and information intelligence teams to deliver infrastructure that's reliable, scalable, and efficient, powering Apple products for billions of users.\nDescription\nWe build the infrastructure that lets developer teams across Search test, measure, and validate the performance of features before they reach billions of Siri users. Our platform captures and replays production-scale traffic so developers can load-test changes in a dev environment and trust that the results are indicative of production behavior. We apply statistical analysis to model how latency, throughput, and resource usage shift from dev to production, helping teams catch performance regressions before they ship. You'll have the opportunity to work with systems processing massive volumes of traffic and results data, with a scale and complexity few teams encounter.\nMinimum Qualifications\n5+ years of experience in software development, including designing, building, and operating large-scale distributed systems and backend infrastructure\nStrong interest in building performance tooling\nStrong software engineering fundamentals in data structures, algorithms, and system design\nExcellent communication and collaboration skills to work effectively with cross-functional teams\nBS, MS, or Ph.D. in Computer Science or a related field, or equivalent experience\nPreferred Qualifications\nStatistical/analytical experience projecting how dev-environment results map to production behavior (regression analysis, capacity modeling)\nHands-on experience designing load test frameworks: traffic capture/replay, configurable load shapes, concurrency control\nExperience with observability tooling for root-causing performance regressions\nFamiliarity with Kubernetes, workflow orchestration and CI/CD pipelines for automating test infrastructure","description_format":"text","description_chars":2272,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":true},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Operating Systems","Laptops","Smartwatches & Fitness Trackers","Tablets"],"lifecycle":[{"event":"open","at":"2026-10-12T10:57:34Z"}],"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":"2026-10-03T21:08:04+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":2996}],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":10,"expected_fill_days":138,"reasons":["conf:2","win:early","comp:brand"],"computed_at":"2026-10-12T19:17:00Z"},"pay":null,"html_url":"https://alion.io/job/apple-staffsr-software-engineer-performance-testing-platform-2","json_url":"https://alion.io/job/apple-staffsr-software-engineer-performance-testing-platform-2.json","meta":{"generated_at":"2026-10-12T19:17:00Z","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":31247,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-13T00:00:00Z"}},"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-staffsr-software-engineer-performance-testing-platform-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-staffsr-software-engineer-performance-testing-platform-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-staffsr-software-engineer-performance-testing-platform-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-staffsr-software-engineer-performance-testing-platform-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fapple-staffsr-software-engineer-performance-testing-platform-2"}]}
