• Stay hands-on with cutting-edge tools and models, particularly LLMs and generative AI, and integrate them into production systems when they solve real problems.

What you Bring:

• 5+ years of experience in data science, with a track record of leading and delivering impactful, production-level projects.
• Demonstrated ability to work independently: proactively identify problems, design solutions, and push projects forward with minimal oversight.
• Strong experience with full-stack data science: data wrangling, modeling, validation, deployment, and monitoring.
• Comfortable setting up your own experiments, pipelines, and direction while ensuring alignment with customer and business goals.
• Experience working with LLMs or generative AI in real-world applications.
• Proficient in Python, SQL, and ML frameworks (e.g., Pandas, Scikit-learn, PyTorch, Hugging Face, LangChain, spaCy/NLTK).
• Deep understanding of experimentation techniques: A/B testing, causal inference, and how to interpret results in a business context.
• Ability to balance scientific rigor with business pragmatism—understanding which experiments are worth running and which aren’t.
• Excellent communication skills and the ability to advocate for data-driven decisions across disciplines.
• A mindset of ownership, resourcefulness, and continuous improvement.
