We explore industry-leading AI technologies, including large language models (LLMs) and multimodal large models, with the goal of developing models that can understand multilingual content and vast amounts of video data, ultimately delivering a better content consumption experience for users. In the Code AI domain, we leverage the powerful code understanding and reasoning capabilities of LLMs to enhance program performance and R&D efficiency.\nProject Introduction:\nMultimodal foundation large models (VLM) represent a research hotspot in the industry and a critical technology for TikTok's business scenario applications. In 2024, TikTok's Innovation Center developed VFM V1, a multimodal large model tailored for TikTok's business scenarios. It matches the performance of the best open-source model Qwen VL on public test sets, while significantly outperforming all other foundation models on TikTok's business test sets. In the future, we aim to continuously develop foundation models with efficient perception and reasoning capabilities, capable of handling multilingual and massive video content understanding algorithms to deliver a better content consumption experience for users.\nProject Challenges:\nEnhance the multimodal perception encoder: The current encoder uses a fixed frame rate. We need to explore more efficient adaptive frame rates while considering the integration of modalities such as audio and user behavior.\nHow to fuse multimodal perception and thinking capabilities to promote stronger comprehensive perception and cognitive abilities of the model.\n任职要求 / Requirements\nMinimum Qualifications:\n- a PhD or Master’s degree in Computer Science, Machine Learning, NLP/CV, Systems, or related fields (or equivalent research experience).\n- Strong programming and debugging skills in Python and/or C/C++; solid data structures & algorithms foundation.\n- Hands-on experience in at least one:\n1. LLMs / generative AI training or adaptation (pretrain, SFT, RL, etc.)\n2. Code intelligence (code understanding/generation, static analysis, compilers/tooling, program repair)\n3. Agentic systems (tool-use, planning, multi-step reasoning, environment interaction)\n- Strong experimental rigor: hypothesis-driven iteration, reproducibility, and clear communication.\nPreferred Qualifications:\n- Publications in top venues (e.g., NeurIPS/ICML/ICLR/ACL/CVPR, and/or systems venues like OSDI/NSDI/SOSP, etc.).\n- Experience with one or more of:\n1. Long-context modeling, retrieval systems, RAG over code, repo-scale indexing\n2. RLHF / verifier-based RL / preference optimization for code tasks\n3. Multi-agent collaboration frameworks and evaluation\n4. Performance engineering: profiling (CPU/heap), latency optimization, cost optimization, or GPU kernel work\n- Programming / competitions (ACM/ICPC, IOI/NOI, Kaggle, TopCoder) is a plus.\nIf you have any questions, please reach out to us at ","description_format":"text","description_chars":3094,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":true},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","Advertising","Social Commerce","Streaming & OTT Platforms"],"lifecycle":[{"event":"open","at":"2026-09-26T11:45:02Z"}],"visa":[],"liveness":{"score":10,"band":"cold","label":"Long shot","p_open":1,"p_active":0.346,"p_room":0.28,"age_days":294,"expected_fill_days":99,"reasons":["conf:0","velocity","win:tail","crowd:junior,brand"],"computed_at":"2026-11-03T05:54:40Z"},"pay":null,"html_url":"https://alion.io/job/tiktok-llm-algorithm-research-scientist-code-ai-intern-ai-innovation-center-2026-soaring-star-talent-program","json_url":"https://alion.io/job/tiktok-llm-algorithm-research-scientist-code-ai-intern-ai-innovation-center-2026-soaring-star-talent-program.json","meta":{"generated_at":"2026-11-03T19:25:54Z","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":1656,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-04T00:00:00Z"}},"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":47},"rest":"https://alion.io/mcp/rest/get_company?id=47"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ftiktok-llm-algorithm-research-scientist-code-ai-intern-ai-innovation-center-2026-soaring-star-talent-program"},{"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%2Ftiktok-llm-algorithm-research-scientist-code-ai-intern-ai-innovation-center-2026-soaring-star-talent-program"},{"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%2Ftiktok-llm-algorithm-research-scientist-code-ai-intern-ai-innovation-center-2026-soaring-star-talent-program"},{"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/tiktok-llm-algorithm-research-scientist-code-ai-intern-ai-innovation-center-2026-soaring-star-talent-program\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ftiktok-llm-algorithm-research-scientist-code-ai-intern-ai-innovation-center-2026-soaring-star-talent-program"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":1301623}},{"tool":"search_jobs","arguments":{"company":"tiktok.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":1301623},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
