You will design, implement, and train a custom decoder-only Transformer from scratch -not fine-tune an existing LLM, but build a purpose\nbuilt architecture for financial time-series.\nThis is a long-term research project with significant computational resources. The successful candidate will have a PhD in machine learning or a related field and demonstrated ability to implement Transformer architectures from first principles.\nPrincipal Responsibilities\nDesign and implement a custom decoder-only Transformer architecture optimized for tokenized financial time-series data\nDevelop a novel tokenization scheme for intraday market data: price movements, volume, order flow, and cross-sectional features\nImplement efficient training pipelines using PyTorch with mixed-precision training, gradient checkpointing, and multi-GPU parallelism\nDesign attention mechanisms adapted to financial data: temporal attention patterns, cross-asset attention, and multi-scale representations\nBuild evaluation frameworks for next-token prediction accuracy, signal quality, and trading performance\nImplement inference optimization for low-latency production deployment: model quantization, KV-cache, speculative decoding\nConduct rigorous ablation studies to validate architecture choices and training methodology\nCollaborate with the team to integrate model predictions into the live trading pipeline\nDocument research methodology, experimental results, and architectural decisions\nRequired Skills / Qualifications\nPhD in Machine Learning, Computer Science, Statistics, Applied Mathematics, or a related field with a focus on deep learning\nDemonstrated ability to implement Transformer architectures from scratch (not just fine­tuning pre-trained models) • Deep understanding of attention mechanisms, positional encodings, tokenization strategies, and training dynamics • Expert-level PyTorch skills including custom modules, training loops, mixed-precision, and multi-GPU training • Strong mathematical foundations: linear algebra, probability theory, optimization, information theory • Experience training models at scale (100M+ parameters) • Strong programming skills in Python and C++ for performance-critical components • Self-directed researcher capable of defining and executing a multi-month research agenda • Familiarity with Al-assisted development tools (Cursor, Claude Code)\nPreferred Skills / Experience\nExperience applying deep learning to financial data or time-series forecasting\nFamiliarity with tokenizatlon approaches for continuous or non-text data\nPublished research in top ML venues (NeurlPS, ICML, ICLR) or equivalent industry experience\nKnowledge of market microstructure and intraday trading dynamics\nExperience with model compression, quantization, and inference optimization\nMillennium offers a total compensation package which includes a base salary, discretionary performance bonus, and comprehensive benefits. The estimated base salary range for this position is $150,000 to $200,000, which is specific to New York and may change in the future. When finalizing an offer, we take into consideration an individual’s experience level and the qualifications they bring to the role to formulate a competitive total compensation package.","description_format":"text","description_chars":3779,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"phd","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Hedge Funds & Alternative Investments"],"lifecycle":[{"event":"open","at":"2026-09-26T07:37:06Z"}],"visa":[],"liveness":{"score":22,"band":"cold","label":"Long shot","p_open":1,"p_active":0.496,"p_room":0.44,"age_days":134,"expected_fill_days":90,"reasons":["conf:3","velocity","win:tail","crowd:brand"],"computed_at":"2026-10-20T05:45:00Z"},"pay":{"stated_usd_annual":200000,"is_top_pay":false},"html_url":"https://alion.io/job/millennium-management-ml-research-scientist-deep-learning-transformer-architectures","json_url":"https://alion.io/job/millennium-management-ml-research-scientist-deep-learning-transformer-architectures.json","meta":{"generated_at":"2026-10-21T05:11:04Z","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":7662,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-22T00:00:00Z"}},"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":704283},"rest":"https://alion.io/mcp/rest/get_company?id=704283"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmillennium-management-ml-research-scientist-deep-learning-transformer-architectures"},{"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%2Fmillennium-management-ml-research-scientist-deep-learning-transformer-architectures"},{"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%2Fmillennium-management-ml-research-scientist-deep-learning-transformer-architectures"},{"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/millennium-management-ml-research-scientist-deep-learning-transformer-architectures\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmillennium-management-ml-research-scientist-deep-learning-transformer-architectures"}]}
