About the role
Do you want to do work that matters, alongside supportive leaders who will help you grow faster than you ever thought possible? Are you a creative problem-solver who is energized by challenges? You’ve come to the right place.
YOUR IMPACT
You’ll blend advanced analytics with semantic modeling to transform raw data into actionable intelligence that shapes products and business strategy.
You’ll design predictive models, run large scale experiments, and surface insights, while also helping define ontologies and knowledge graphs that connect and contextualize enterprise data.
Partnering with engineers and domain experts, you’ll establish data standards, ensure quality, and operationalize models and graph services at scale. The solutions you deliver will accelerate innovation, improve client experiences, and enable faster, more confident decision making across the Platform.
As a member of the Platform team, you will collaborate with the Client Capabilities Network team to deliver state-of-the-art generative AI automations.
You will experience what it’s like to develop a generative AI product with a firm-wide impact. You’ll join a cross-functional team of data scientists, engineers, designers, and product managers working on a high-priority initiative. Leveraging cutting-edge technology, we aim to revolutionize how we conduct and synthesize knowledge research, enabling firm members to deliver impactful stories effortlessly.
You will work hands-on with the latest multimodal LLMs, conducting experiments and deploying production pipelines that utilize generative models (such as GPT-like models) for automating knowledge search, curation, and synthesis processes. This includes model training, fine-tuning, evaluation, and iteration, enhancing creativity and content generation.
