# Mengmeng Ji > ML, LLM @ Sambanova Location: San Francisco Bay Area, United States Profile: https://flows.cv/mengmengji Machine Learning Engineer & LLM Researcher focused on inference-time optimization and model-level efficiency. My work centers on improving efficiency–accuracy tradeoffs in large language models through speculative decoding, speculative prefill, and long-context optimization. I design and evaluate new inference-time methods, supported by scalable training, benchmarking, and experimental pipelines. My experience spans model development, finetuning strategies, and evaluation infrastructure, enabling end-to-end optimization from training to test-time behavior. I have also worked on agentic LLM systems and diffusion-based text models. Always looking forward to exploring exciting research topics and collaborations. ## Work Experience ### Senior Software Engineer @ SambaNova Systems Jan 2025 – Present | Palo Alto, California, United States ### Software Engineer and NLP Researcher @ SLB Jan 2024 – Present | Menlo Park, California, United States ### Software Engineer @ Gridspace Jan 2022 – Jan 2022 | Los Angeles, California, United States MarketingWebsite Overhaul • Designed and implemented new features focusing on user conversion and enhancing first-time visitor experiences for company’s marketing website using Django and React. • Implemented a secure and low-friction registration process, including cross-domain (CORS) authentication utilizing Django with dynamic URL construction and secure cookie handling. • Utilized JavaScript, Bootstrap and SASS with the React framework to implement dynamic client-side pages for chatbot demo and personalized pop-up page. Phoneme Precision Tracker: TTS Attention Analysis & Enhancement • Developed a Python-based Text-to-Speech (TTS) tracking tool for chatbots, pinpointing pronunciation errors at the phoneme level to boost speech clarity. • The tool achieved a runtime 1/100th of the TTS model’s, ensuring easy integration. • Implemented sentence and paragraph processing algorithms, conducted extensive testing with NumPy for reliability and accuracy. Data Preprocessing Tool • Enabled the prevailing Tacotron2 TTS model to utilize FastSpeech2 capabilities by creating an automatic data labeling preprocessor. ### Global Campaign Marketing Strategist @ Indiegogo Jan 2021 – Jan 2021 | San Francisco Bay Area • Consulted with companies on Indiegogo, guiding product marketing strategies and providing comprehensive feedback on digital launch strategies, marketing assets, and copywriting, signicantly enhancing the performance of 8 campaigns, with some achieving fundraising of over $500k. • Leveraged Python and Pandas for data analysis and conducted comprehensive interviews across departments to research and implement strategies for optimizing campaign performance, ensuring a balanced decision-making process between quantitative data and experiential insights. • Supported product management e orts, including shadowing a product manager to establish operational lines and goals for new projects and facilitating cross-functional team meetings. • Participated in the quality assurance process, conducting performance testing on several projects to ensure product excellence and reliability. ## Education ### Doctor of Philosophy - PhD in East Asian Languages and Cultures Stanford University ### Harvard Yenching Visiting Fellow in East Asian Languages, Literatures, and Linguistics Harvard University ### Bachelor's degree in Chinese Language and Literature Fudan University ## Contact & Social - LinkedIn: https://linkedin.com/in/mengmeng-ji --- Source: https://flows.cv/mengmengji JSON Resume: https://flows.cv/mengmengji/resume.json Last updated: 2026-04-01
