Principal Applied Scientist

Invent, implement and deploy state-of-the-art machine learning and/or specific domain industry algorithms and systems. Build prototypes and explore conceptually new solutions. Work collaboratively with science, engineering, and product teams to identify customer needs in order to create and implement solutions, promote innovation and drive model implementations. Applies data science capabilities and research findings to create and implement solutions to scale. Responsible for developing new intelligence around core products and services through applied research on behalf of our customers.

Develops models, prototypes, and experiments that pave the way for innovative products and services.

We are seeking an exceptional Principal Applied Scientist with deep expertise in Responsible AI to join our fast‑growing AI/ML research team. In this role, you will drive the development and evaluation of scalable safeguards for foundation models, with a focus on large language or multi‑modal models (LLMs/ LMMs). Your work will directly influence how we design, deploy, and monitor trustworthy AI systems across a broad range of products.

• Conduct cutting‑edge research and development in Responsible AI, including fairness, robustness, explainability, and safety for generative models
• Design and implement safeguards, red teaming pipelines, and bias mitigation strategies for LLMs and other foundation models
• Contribute to the fine‑tuning and alignment of LLMs using techniques such as prompt engineering, instruction tuning, and RLHF/DPO.
• Define and implement rigorous evaluation protocols (e.g., bias audits, toxicity analysis, robustness benchmarks)
• Collaborate cross‑functionally with product, policy, legal, and engineering teams to ensure Responsible AI principles are embedded throughout the model lifecycle
aangek
• Publish in top‑tier venues (e.g., NeurIPS, ICML, ICLR, ACL, CVPR) and represent the company in academic and industry forums

• Ph.D骑 in Computer Science, Machine Learning, NLP, or a related field, with publications in top‑tier AI/ML conferences or journals
• Hands‑on experience with LLMs including fine‑tuning, evaluation, and prompt engineering
• Demonstrated expertise in building or evaluating Responsible AI systems (e.g., fairness, safety, interpretability)
• Proficiency in Python and ML/DL frameworks such as PyTorch or Tensor rapped
• Strong understanding of model бараva evaluation techniques and metrics related to bias, robustness, and toxicity
• Creative problem‑solving skills with a rapid prototyping mindset and a collaborative attitude

• Experience with RLHF ( Query which) or other alignment methods
• Open‑source contributions in the AI/ML community
• Experience working with model guardrails, safety filters, or content moderation systems

You’ll be working at the intersection of AI innovation and Responsible AI, helping shape the next generation of safe and trustworthy machine learning systems. If you’re passionate about ensuring AI benefits everyone—and you have the technical depth to back it up—we want to hear from you.

This role is critical to advancing our AI strategy by accelerating the development and deployment of scalable, production‑grade machine littering solutions that directly support customer use cases and drive differentiation in our core products. By combining cutting‑edge research with applied innovation
, this role will enable us to:

• Address high‑priority technical gaps in areas such as model safety, bias mitigation, explainability, and performance optimization
• Increase customer trust and adoption through more robust and responsible AI systems
đều
• Strengthen our IP portfolio and thought leadership through novel model development and peer‑reviewed publications

This position not only supports innovation but directly impacts revenue, customer satisfaction, and competitiveుఖ advantage by ensuring our AI systems are performant, responsible, and aligned with user needs.
