Job Description
We’re hiring a software engineer to work with our small, full-stack team to build products to test, monitor, and improve predictive and generative AI systems.
You’ll be responsible for building our products with a focus on backend, such as working with web servers, SQL databases, AI/ML libraries (e.g. LangCheck), API design, multi-cloud architecture, integrating with external services (e.g. SSO), and general functionality to test AI models and datasets.
Our backend is primarily in Python. Some technologies we use are: Docker, SQLite, Redis, RQ, Gunicorn, Flask, Pytest, and many Python AI/ML libraries.
As an early employee, you’ll own a significant equity stake in addition to your base salary.
Qualifications
Our company, technology, and market are new and changing rapidly, so a large part of the job is to adapt and learn new things. We value learning fast over pre-existing knowledge (“slope is more important than y-intercept”).
You should have at least 2 years of experience with web backends or AI/ML applications in production. Some background in AI/ML is preferred, but not strictly required. We don’t require past experience with specific programming languages or frameworks.
English is required, Japanese is optional. We prioritize candidates in Tokyo, but may consider remote for exceptional candidates.
About the Company
Citadel AI builds software products to test and monitor high-risk AI systems. Our mission is to make the world’s AI systems more reliable and trustworthy.
We’re located in Tokyo, but we have an international team and global customers. Our goal is to build a world-class startup from Japan, and our team members have previously worked at leading companies such as Google, Waymo, Paidy, Toyota, Apple, and Stripe.
This is a unique opportunity to build new products for a global market from Tokyo. As an early employee at Citadel AI, you’ll have significant impact and ownership over the growth of our startup. We raised a Series A last year from Japan’s top investors, and are currently scaling our business in the 1 → 10 stage.
