They combine technical deep learning, business acumen, and engineering expertise with an entrepreneurial mindset driven by rapid experimentation, first-principles thinking, and a passion for tackling complex real-world problems to deliver lasting impact.
As an applied scientist intern, you will identify the most impactful problems to solve, translating commercial objectives into technical solutions. You will combine and transform large multimodal datasets to run in-depth statistical analysis, and apply deep learning models to automate large-scale decisions, integrated into live business processes, designed to generate tangible economic impact.
We are looking for team players who have excellent quantitative abilities and:
- A degree in computer science, mathematics, statistics, physics, economics, or similar fields from a leading university
- In-depth understanding of mathematical and statistical concepts behind the most common machine learning techniques
- Familiarity with frontier lab APIs (Gemini, OpenAI, Anthropic), and their advanced features like structured outputs and tool calling
- Understanding of LLM inference considerations e.g. input vs. output tokens, prompt caching
- Experience working with deep learning models within natural language processing or computer vision (e.g. HuggingFace model import/fine-tuning /inference)
- Experience writing code in Python
- Experience and willingness to work through the challenges associated with large, unstructured, real-world data sets in a client-facing setting
- Ability to see solutions and opportunities that others do not see
- High level of commitment and reliability, good balance of pragmatism and perfectionism
Bonus if skilled in any of the following tools and/or languages:
- Cloud Infrastructure
