In this role, you will bridge the gap between cutting-edge academic research and production-grade AI infrastructure. You will build, design, and fine-tune large-scale architectures (including LLMs, Multimodal, and Tabular Foundation Models) while applying them to complex, real-world domains like agentic behavior, coding and decision making.\nIn your day-to-day, you will:\nConduct pioneering research in deep learning and generative AI, specializing in Foundation Models, NLP, alignment, and multimodal learning \nDeal with the impact of the models on production traffic, cost quality and latency\nTrain and scale state-of-the-art architectures using techniques like Post-Training SFT, Knowledge Distillation, LoRA, and sparse/hybrid model architectures \nOwn the AI lifecycle-from algorithmic prototyping and synthetic data generation to deploying production-grade AI features in fast-paced or big-data environments\nDrive research initiatives, author publications/patents, and collaborate with other research teams to integrate intelligent capabilities into core products \n 5+ years of experience as a Research Scientist or Algorithm Developer within world-class AI labs or high-growth GenAI startups \nPh.D. or Master’s degree with honors in computer science, data science, statistics, or a highly quantitative field from a top-tier institution \nExpert-level proficiency in PyTorch and deep learning training/inference optimization \nHands-on experience training, fine-tuning, or optimizing large-scale LLMs in research or production environments \nAdvanced programming skills in Python and/or C/C++ with experience in production-grade code and big data infrastructure \nA portfolio of peer-reviewed publications in top-tier AI/ML venues or granted patents in advanced machine learning systems \n We're Base44, a newly acquired part of Wix, on a mission to redefine how software is built. Our AI-powered platform enables anyone to create custom software applications using natural language-no coding required. Operating like a startup within Wix, we're fast, collaborative, and focused on solving complex problems with simple, powerful solutions.\nWe exist to empower creators, solo founders, startups, entrepreneurs, and side hustlers to bring their ideas to life. Whether you're launching a product, validating a concept, or exploring a new idea, Base44 is here to help you build it.\nWe're growing rapidly, the potential is immense, and with your expertise, we can drive user-driven growth to new heights.","description_format":"text","description_chars":2645,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"All levels","optional":false}]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Website Builders"],"lifecycle":[{"event":"open","at":"2026-06-17T10:09:43Z"}],"visa":[],"liveness":{"score":10,"band":"cold","label":"Long shot","p_open":1,"p_active":0.348,"p_room":0.28,"age_days":140,"expected_fill_days":26,"reasons":["conf:1","velocity","win:tail","crowd:"],"computed_at":"2026-11-05T05:54:30Z"},"pay":null,"html_url":"https://alion.io/job/wix-ai-researcher-foundation-models-generative-ai-base44","json_url":"https://alion.io/job/wix-ai-researcher-foundation-models-generative-ai-base44.json","meta":{"generated_at":"2026-11-05T06:03:00Z","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":7433,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-06T00:00:00Z"}},"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":3668},"rest":"https://alion.io/mcp/rest/get_company?id=3668"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fwix-ai-researcher-foundation-models-generative-ai-base44"},{"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%2Fwix-ai-researcher-foundation-models-generative-ai-base44"},{"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%2Fwix-ai-researcher-foundation-models-generative-ai-base44"},{"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/wix-ai-researcher-foundation-models-generative-ai-base44\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fwix-ai-researcher-foundation-models-generative-ai-base44"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":31088}},{"tool":"search_jobs","arguments":{"company":"wix.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":31088},"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.
