Prompt Engineer I LangChain Developer
Etonwood Limited is hiring two AI Engineers for an Innovative Systematic Trading firm.

Candidates should have strong Python, NLP, and ML skills, with a keen interest in Quantitative Trading.
Our long-standing client, an Innovative Systematic Trading firm, is looking to invest in 2 AI Engineers. The Head of Research & Development seeks two individuals who will have input into the training of LLMs and transformers. A core focus will be the productionisation of these models and the development of APIs to enable both the Quantitative Research and Trading communities’ access to bespoke X-Asset Analytics ‘on the fly’.
For one role, they desire a hybrid ML Engineer and Data Scientist with deep NLP models knowledge, coupled with expert Python programming skills including NLTK, SpaCy, Bert and Hugging Face, for the design and build of GPT Extensions / Plugins.
For the second role, a marriage of true Software Engineering, ML as core with Data Engineering (at scale, Hadoop, Spark, Kafka) and proven experience building Python-based APIs to enable access to existing and future Cloud Based Pre and Post Trade Analytics data via the Chatbot.
Given this is truly cutting-edge, existing Markets domain knowledge is not required. However, a genuine interest in Quantitative Trading is essential, so previous experience in Quant Research/Development before pivoting to Machine Learning, or education in Math / Finance with retained knowledge is required.
