You are passionate about pushing distributed query engines to their limits and getting every ounce of performance out of them, while matching Spark’s results exactly. We are looking for engineers with in-depth knowledge of Spark internals and of related technologies such as Apache Iceberg, Parquet, Arrow, and DataFusion. You are also excited about working in the open, collaborating with teams across Apple that run Spark at scale and contributing upstream to these open-source communities.\nDescription\nAs an engineer on our team, you will advance Apple Data Platform by making Apache Spark faster and more efficient with Apache DataFusion Comet. You will design and implement operators and expressions in a native language on Apache DataFusion and Apache Arrow, extend Comet’s Spark integration across Spark versions, and accelerate reads and writes of Apache Iceberg and Apache Parquet data, all while keeping results identical to Spark’s. You’ll collaborate closely with a dedicated team of open-source data experts, including committers to Apache Spark, DataFusion, and Iceberg, among others, and contribute that work upstream. You will also profile and benchmark real workloads and tune memory, shuffle, and I/O to roll Comet out reliably across both data centers and cloud services. Your work will directly contribute to the resilience, scalability, and performance of systems that support millions of users worldwide.\nMinimum Qualifications\n3+ years of professional software engineering experience.\nA proven track record of building distributed systems.\nContributor or committer to Apache Spark and/or Apache DataFusion, Comet.\nBS, MS, or PhD in Computer Science or a related field, or equivalent practical experience.\nPreferred Qualifications\nExperience with columnar or vectorized query execution, or with performance profiling and optimization of query engines.\nGood knowledge of Apache Iceberg and Apache Parquet internals.\nExperience working on or building Spark connectors to external data sources.\nKnowledge of Kubernetes, or other compute platforms.","description_format":"text","description_chars":2261,"description_truncated":false,"requirements":{"experience_years_min":3,"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":"2026-10-12T17:08:32Z"}],"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":60,"band":"ok","label":"Likely open","p_open":1,"p_active":0.602,"p_room":1,"age_days":0,"expected_fill_days":36,"reasons":["conf:1","stale_co","win:early","comp:brand"],"computed_at":"2026-10-13T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/apple-senior-software-engineer-apple-data-platform","json_url":"https://alion.io/job/apple-senior-software-engineer-apple-data-platform.json","meta":{"generated_at":"2026-10-13T10:44:01Z","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":16503,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-14T00:00:00Z"}},"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-senior-software-engineer-apple-data-platform"},{"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-senior-software-engineer-apple-data-platform"},{"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-senior-software-engineer-apple-data-platform"},{"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-senior-software-engineer-apple-data-platform\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fapple-senior-software-engineer-apple-data-platform"}]}
