Position: Founding Software Engineer in San Francisco - Athina AI

Skills:Node.js, Python, React, SQL

Overview:

Athina is building an IDE to enable the development of AI-powered products. We are on a mission to build the new stack for AI product teams. This means defining how teams will prototype, experiment, train, evaluate and monitor GenAI products.

The next decade will enable AI-powered products and features that areradicallydifferent from the software we have been building until now. This is an open-domain unsolved problem, and we’re looking for tinkerers, hackers, and creatives who want to build the toolkit for the next decade of software.

The role:

Minimum requirements:

  • Min. 5+ years of experience as a SWE
  • Strong frontend + backend skills (if you're more frontend or backend-leaning, that's fine!)
  • Experience creating complex software systems from the ground up
  • A strong IC who is a self-starter and can work independently

Ideal requirements:

  • You are excited about GenAI and are tinkering and hacking
  • You are excited about the challenge of figuring out unsolved problems
  • Based in SF, or willing to relocate (on-site but flexible working)
  • Start-up or founding engineer experience is ideal
  • Experience with AI is a plus but not a hard requirement

What we look for:

We're a small team, so we’re looking for someone who can tackle complex problems end-to-end. The job is not to write code. We are looking for someone to create a product that solves the problem and delights users!

What you'll be building:

GenAI development is an open-domain problem and requires a lot of creativity, tinkering and experimentation. We require a strong work ethic, and in return we promise you the same.

Problems we're solving:

  • How to generate, curate and annotate data for training and testing
  • How to evaluate complex AI products
  • How to prototype and test complex AI agents

Stack:

  • Postgres DB
  • (Node.js + Typescript) API server
  • (Python) Workers for running evaluations and background jobs
  • (Python) Open-source evaluations library
  • (React.js + Typescript) Frontend
