Job Title

Job Description At Oracle Analytics, we are building the next generation of enterprise AI products to enable intelligent data analysis at scale. Leveraging our foundational strengths in data management and enterprise software applications, we are advancing our platforms and applications by deeply embedding cutting-edge agentic AI, generative AI, and innovations in machine learning and optimization.We are seeking a Senior Applied Scientist to perform innovation in learning from human feedback (LFHF) and user preference modeling, with a strong focus on in-context learning and post training for large language models. You will design data and feedback strategies, build preference/reward models, and develop post training pipelines (e.g., SFT, DPO, RLHF/RLAIF) that deliver safe, high-quality, and cost-efficient enterprise AI experiences. You will partner closely with research engineers and product teams to ship aligned models to production, instrument rigorous evaluation, and drive measurable customer and business impact. Responsibilities What you will dou2022 Perform end to end LFHF programs: define annotation rubrics, sampling strategies, and quality controls; design rater guidelines and human in the loop workflows in collaboration with product/UX and data engineering. u2022 Build preference and reward models: pairwise and listwise modeling, win rate optimization, uncertainty estimation, and active learning to improve sample efficiency and data quality. u2022 Develop post training pipelines: supervised fine tuning (SFT), direct preference optimization (DPO/IPO/ORPO), RLHF/RLAIF, and distillationu2014balancing quality, safety, latency, and cost for enterprise workloads. u2022 Advance in-context learning: retrieval augmented prompting, dynamic few shot selection, tool use/orchestration aware prompting, instruction following, and mitigation of ICL brittleness and context overflow. u2022 Optimize inference and efficiency: PEFT/LoRA/QLoRA, quantization, speculative decoding, caching, and distillation for scalable deployment on Oracle infrastructure. u2022 Evaluate rigorously: establish offline/online metrics, pairwise and rubric based human evals, red teaming, safety/guardrail tests, A/B experiments, and win rate tracking; perform offline policy evaluation where applicable. u2022 Ensure safety, privacy, and compliance: apply content safety policies, guardrail configuration, PII handling/redaction, differential logging, and model governance appropriate for regulated enterprise settings. u2022 Productionize solutions: collaborate with platform teams to ship models and evaluation services; implement observability, telemetry, canarying, rollback, and lifecycle management.u2022 Stay current with research and translate advances into production differentiators; mentor teammates and contribute to a culture of scientific rigor and impact.Minimum qualificationsu2022 MS, PhD (preferred) in Computer Science, Machine Learning, Statistics, Electrical Engineering, or related field with a focus relevant to LFHF, reinforcement learning, NLP, or human AI interaction. u2022 Experience (industry or applied research) building and deploying ML systems, including LLM post training and evaluation. u2022 Demonstrated expertise in learning from human or AI feedback: data/rubric design, preference/reward modeling, and optimization methods (e.g., SFT, DPO, RLHF/RLAIF). u2022 Strong background in in context learning, prompt/program design, retrieval augmented generation, and model alignment for accuracy, safety, and robustness. u2022 Proficient in Python and modern ML stacks: PyTorch/JAX, Transformers, and libraries for post training and evaluation; solid software engineering practices and experimentation discipline. u2022 Track record publications in top venues (e.g., NeurIPS, ICML, ICLR, ACL, EMNLP, NAACL).Preferred qualifications u2022 Experience designing at scale data pipelines for feedback collection, active learning, and rater operations; familiarity with label quality auditing and bias/variance trade offs.u2022 Knowledge of bandits/off policy evaluation, causal inference for policy changes, and statistical testing for online experiments. u2022 Familiarity with LLM efficiency and serving: tensor/graph optimization, KV cache management, batching strategies, and throughput/latency trade offs. u2022 Experience integrating safety/guardrails, policy enforcement, and privacy preserving telemetry into production workflows aligned with enterprise compliance. u2022 Comfortable collaborating across research, engineering, product, and legal/compliance; excellent communication skills to explain methods and results to technical and non-technical stakeholders. u2022 Practical experience with experiment tracking, model registries, and CI/CD for ML Career Level - IC3 Disclaimer: Certain US customer or client-facing roles may be required to comply with applicable requirements, such as immunization and occupational health mandates.
