Job descriptionModel Quality in Real‑World Workflows : Improving synthesis, summarization, grounding, and structured reasoning in a government contracting and proposal context. Custom Evaluation and Feedback Loops : Designing robust ways to evaluate relevance, completeness, hallucination risk, and user‑centric performance. Latency, Scale, and Control : Balancing performance and cost across open and closed models while building a testbed for fine‑tuning and long‑context optimization. Build and improve model‑powered product features that help federal contractors reason faster and act with confidence. Enhance grounding, summarization, and generation systems across Vultron’s modular proposal workflows. Develop and refine retrieval systems using RAG, vector search, and knowledge graphs. Design evaluation pipelines that go beyond BLEU or ROUGE — measuring utility, accuracy, and synthesis quality in noisy, complex documents. Work closely with federal domain experts to translate expertise into scalable model strategies. Conduct experiments with fine‑tuning, synthetic data generation, and in‑context learning to improve performance across retrieval and summarization tasks. Experience fine‑tuning and prompting large models — particularly agentic or task‑specific systems — and improving performance through grounding, context window optimization, or RAG. Experience researching and building LLM‑based systems, including both training and deployment. Significant contributions to the AI field via top‑tier conferences or open‑source projects. Proven ability to work closely with engineers, product teams, and non‑technical experts to ship fast and stay aligned. Ph.D. or M.S. in Computer Science, Machine Learning, or a related field (or equivalent industry experience). Must be located in the SF Bay Area or be willing to relocate. 5+ years of experience in ML research, applied LLMs, or model infrastructure. Experience with scalable LLM systems using LangChain, LlamaIndex, Hugging Face, or similar frameworks. Familiarity with GPU‑based experimentation and cloud model deployment (e.g., vLLM, DeepSpeed, Ray Serve). Experience with RAG pipelines and evaluation frameworks like RAGAS, DSPy, or LLaMAEval. Background as an early engineer in a rapidly growing startup.
