  • Direct experience leveraging LLMs in production, and an in depth understanding of prompt design, agentic workflows, eval harnesses, retrieval pipelines, etc.
  • Exposure to LLM inference stack fundamentals such as KV Caching, Speculative Decoding, Parallel Decoding, and test-time compute ideas.
  • Excellent programming, technology, and system design skills, including an in-depth understanding of and recent programming experience with Python and ideally one of C++, Java, or .Net
  • Experience working with SQL databases
  • Azure or AWS experience
  • A strong enthusiasm for programming and technology and an appetite to work in a dynamic and integrated team
  • An entrepreneurial nature, willing to take ownership and run towards problems and someone who thrives on innovation
  • The ability to own all aspects of an AI project from start to finish
  • A desire to understand and solve business problems, build domain knowledge and increase market understanding
  • The ability to communicate clearly and professionally with our clients as well as team members
  • Financial Services experience a bonus, but is not essential
  • Bachillerato grades of 9.0 and above, and at least a 7.0 in a bachelor’s degree in computer science, mathematics, a hard science, or a related field from a top university

Why join us?

  • Push the boundaries of what is possible, and re-imagine how bleeding edge AI can be used to deliver commercial value

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
