About ModelML
Model ML is an AI tool that speeds up research and due diligence for the financial sector: investment banks, family offices, private equity, VCs etc.

We're two brothers both building our second YC company. Arnie previously built Fancy (S17), raised ~$6 million in funding, and later sold to Gopuff. Chaz previously built FatLlama (S17), raised ~$15 million in funding, and later sold it to Hygglo.

We LOVE building cool stuff in HUGE markets.

About the Role
Full-stack / Backend Engineer

Backend: Python, FastAPI, Celery, Redis, AWS, Docker (optional)
Note, if you have used other Python Frameworks e.g. Flask/Django, or if you know python and are killer with node/golang backends, that can also work.

Frontend: Nextjs / React, Typescript
Fundamental knowledge of LLMs: embeddings, RAG, vector databases etc...

We are mainly looking for a profile with strong backend (and solid infra/devops) experience. However, given that we are still in the early stages, we are open to hiring a "generalist" if you impress us! You will be the third engineering hire, with full ownership over our backend business logic and architecture. You will also help grow our team culture and will work closely with the founders (obviously!).

What It Will Be Like

  • It won't be easy; in fact, it will be very hard.
  • BUT, it will be a lot of fun.
  • You will be directly involved in shipping incredible software to our customers, and you will see it make a difference in their daily lives.
  • You need to be comfortable in being uncomfortable; timelines will change, priorities will most likely shift
  • Be prepared to sacrifice your work-life balance in exchange for joining an incredible journey and learning a lot along the way.

Our Process
We're very conscious of everyone's time, so we want to make the process as efficient as possible.

  • Call 1: 20-minute intro call with Arnie/Chaz If you proceed:
  • Call 2: 20-minute follow-up with whoever you didn't speak to first
  • Call 3 (if required): 10-15 minute call to deep dive into specific areas if deemed necessary.

Your Application
If you apply, we'd love for you to tell us about the most impressive thing you've ever built in place of a cover letter. As well as this, please include your:

  • GitHub URL
  • LinkedIn URL
  • Tech stacks you are comfortable with (please grade them 1-5, with 5 being the best known)

Building on top of Open AI. AI expert desired but no essential. Front & backend skills bonus too.
