The team aims to establish state-of-the-art (SOTA) models while delving deeply into these areas to optimize algorithms for e-commerce data, thereby enhancing business outcomes. By refining algorithms and collaborating with business operations, the team strives to govern the quality and ecosystem of ByteDance's e-commerce products comprehensively. This includes addressing issues such as risks, violations, and low-quality content, while also fostering the e-commerce ecosystem. The ultimate goal is to maximize platform governance efficiency and effectiveness.\nJob Responsibilities\n- Large language Model Algorithm Development: Build domain-specific large language models (LLM/MLLM) for e-commerce, integrating domain knowledge to rapidly apply models to business scenarios.\n- E-commerce Governance Optimization: Understand e-commerce governance scenarios deeply to improve merchant/product/video/live-stream/IPR governance through algorithm optimization. Develop state-of-the-art intelligent review systems capable of “knowing why to reject” decisions.\n- Model Enhancement: Handle tasks like data construction, foundational model enhancement, instruction fine-tuning, chain-of-thought (CoT) , and parameter-efficient fine-tuning (PEFT) to achieve optimal model performance in the e-commerce domain.\n- Problem Solving for Governance Applications: Address challenges such as long text/sequence modeling, few-shot learning, content moderation, violation detection, and policy recommendation using large models and multimodal approaches.\n- Model Development and Optimization: Research and optimize e-commerce-specific NLP and multimodal large models to improve multilingual, multi-task, and multi-modal algorithm performance across various e-commerce scenarios.\n任职要求 / Requirements\nMinimum Qualifications\n- Strong Technical Background: Solid foundation in machine learning and familiarity with cutting-edge AI technologies. Preference for candidates with high-quality academic publications or competition experience.\n- Big Data Proficiency: Familiarity with big data frameworks and applications like MapReduce/Spark is preferred.\n- Model Training Expertise: Experience with training and deploying TensorFlow/PyTorch models. \n- Model Compression and Inference Optimization: Understanding of research and techniques for model compression and inference acceleration, including quantization, pruning, distillation, and TensorRT optimization.\nPreferred Qualifications\nExpertise in One of the Following Areas:\n- Computer Vision (CV) & Multimodal:\nIn-depth knowledge in fields such as image search, classification, segmentation, detection, OCR, graph neural networks, multimodal learning, unsupervised/self-supervised learning, etc.\nExperience in CV/multimodal large model projects is preferred, especially for e-commerce scenarios like video/product multimodal modeling.\nStrong practical abilities, with achievements in competitions such as Kaggle, COCO, ImageNet, ActivityNet, ICPC, etc.\nPublications in top-tier conferences (e.g., CVPR, ICCV, ECCV) are a plus.\n- Natural Language Processing (NLP):\nExpertise in areas such as pretraining, NLU, multilingual and cross-lingual learning, NLG, transfer learning, and semi-supervised learning.\nExperience in LLM-related projects and applying them to unify e-commerce NLP tasks is a plus.\nStrong practical abilities, with achievements in competitions like Kaggle, GLUE, Super GLUE, CLUE, etc.\nPublications in top-tier conferences (e.g., ACL, EMNLP) are a plus.\n- Knowledge of training acceleration methods such as mixed precision training and distributed training is a plus.","description_format":"text","description_chars":3739,"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":["Commerce","Advertising","Recommendation Systems","Digital Media"],"lifecycle":[{"event":"open","at":"2026-09-25T16:14:41Z"}],"visa":[],"liveness":{"score":58,"band":"ok","label":"Likely open","p_open":1,"p_active":0.799,"p_room":0.72,"age_days":202,"expected_fill_days":429,"reasons":["conf:1","velocity","win:mid","crowd:brand"],"computed_at":"2026-10-16T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/bytedance-llmmllm-algorithm-engineer-global-e-commerce","json_url":"https://alion.io/job/bytedance-llmmllm-algorithm-engineer-global-e-commerce.json","meta":{"generated_at":"2026-10-17T04:56:34Z","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":6456,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"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":13},"rest":"https://alion.io/mcp/rest/get_company?id=13"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fbytedance-llmmllm-algorithm-engineer-global-e-commerce"},{"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%2Fbytedance-llmmllm-algorithm-engineer-global-e-commerce"},{"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%2Fbytedance-llmmllm-algorithm-engineer-global-e-commerce"},{"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/bytedance-llmmllm-algorithm-engineer-global-e-commerce\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fbytedance-llmmllm-algorithm-engineer-global-e-commerce"}]}
