Job Level

About the role

  • Develop LLM-powered intelligent experiences that interpret and generate insights from both tabular and unstructured data.
  • Build and optimize personalized Q&A systems using large language models, enabling context-aware responses tailored to user needs.
  • Design and enhance conversational talent recommendation systems, combining autonomous agent architectures with personalized recommendation algorithms.
  • Advance traditional recommendation systems by evolving them from simple ranked lists to multi-topic, interactive experiences that better reflect user intent.
  • Construct multi-agent intelligent workflows that translate natural language inputs into complex, goal-directed task sequences.
  • Collaborate within a highly cross-functional team, including data scientists, machine learning engineers, product managers, and UX designers.
  • Partner with fellow data scientists to design, prototype, and iterate on AI/ML models and system architectures.
  • Work closely with machine learning engineers to deploy, monitor, and optimize scalable AI/ML solutions in production environments.
  • Collaborate with product managers to design intuitive user experiences, define feedback loops, and analyze user telemetry to guide product improvements.
  • Engage in end-to-end AI/ML product development, from ideation to deployment, while continually expanding your technical and product skillset.
  • Follow and help define robust development standards to ensure the creation of trustworthy, safe, and responsible AI systems.
  • Contribute to internal and external AI/ML research through experimentation, whitepapers, and collaboration with the broader AI community.

Requirements

  • Proven experience deploying high-risk NLP applications in real-world, production environments—such as those involving regulatory compliance, privacy, safety, or fairness.
  • Demonstrated ability to advance and implement Trustworthy AI and Responsible ML practices, working cross-functionally with engineering, legal, policy, and product stakeholders across a large enterprise.
  • Track record of mentoring and coaching junior data scientists, especially in navigating ambiguous or novel problem spaces.
  • Strong applied machine learning experience, with solid foundational knowledge in statistics, optimization, and deep learning—preferably gained at leading technology companies (e.g., Google, Meta, Microsoft) or AI-first startups.
  • Excellent communication skills with the ability to synthesize complex technical work into accessible insights for executive briefings, research publications, and external presentations.
  • Advanced proficiency in Python and common ML/DS libraries such as NumPy, pandas, scikit-learn, as well as deep learning frameworks like TensorFlow, PyTorch.
  • Experience designing and deploying scalable deep learning systems, including neural network architecture optimization, model distillation, quantization, or on-device inference.
  • Strong understanding of machine learning infrastructure, including experience with Kubeflow, MLflow, Airflow is a plus.
  • 12+ years of industry experience, with a demonstrated ability to take ownership of complex projects and deliver impactful AI/ML solutions from concept to production.
