Junior Research Scientist

Junior Research Scientist - Series E AI Unicorn | NYC | On-Site

I'm working with one of the fastest-growing enterprise AI companies in the US as they continue to scale their core Research team in New York.

This isn't another early-stage AI company experimenting with LLMs. This business is already operating at serious scale:

• $250M Series E led by Andreessen Horowitz (a16z)
• $400M+ raised to date
• Recently surpassed $200M ARR
• 100% YoY growth for 5 consecutive years
• Technology used across 1 in 6 US apartments
• More than 1B AI-powered conversations processed

They're now looking for a Junior Research Scientist to work directly on the machine learning and LLM systems powering that scale.

You’ll join a high-calibre research group working across LLMs, machine learning, predictive modelling and applied AI research
, taking ideas from research through to production.

• Developing and improving ML architectures for sophisticated conversational AI systems
• Working with the latest large language models on production-scale datasets
• Building predictive models around user behaviour and engagement
• Applying advanced mathematics, statistics and ML to difficult real-world problems
• Experimenting with new research and translating it into production systems
• Working closely with Engineering, Product and Data Science to deploy models at scale

This is particularly well suited to someone coming from a highly quantitative academic background:

PhD in Mathematics, Theoretical Physics, Computer Science or a closely related field

• Strong foundations in machine learning, statistics and mathematical modelling
• Excellent quantitative problem-solving ability
• Strong Python skills and experience with modern ML frameworks
• Genuine interest in LLMs / generative AI / applied ML research
• The ambition to work in an intense, high-ownership startup environment
