About Ethos

Ethos is on a mission to transform how banks govern their AI and machine learning models. We're an early-stage startup in NYC backed by leading investors, including Better Tomorrow Ventures and Capital One Ventures.

AI and machine learning models are already used today for many of the most critical decisions in society. Especially in financial services, this technology comes with deep questions around testing and governing these models to make sure their behaviors are trustworthy.

We started Ethos because we saw firsthand the critical need for a modern platform for Model Risk Management in financial services. Changing technologies and regulatory requirements pose huge challenges for the industry, as well as enormous opportunities for positive change. At Ethos, you will be a fundamental part of this change.

The opportunity

We’re looking for a Full-Stack Founding Engineer to join as one of our first hires. You’ll be on the ground floor of building a fast-growing startup. We have an early product, amazing design partners, and an exciting road ahead.

We value collaboration, learning, and the challenging journey of building something from scratch together. We prioritize quality and meaningful change.

You’ll be tackling the financial industry's toughest problems with craftsmanship and innovation. You’ll be developing a groundbreaking product and facing new challenges head-on every day.

You will become a foundational part of the Ethos journey, directly influencing every aspect of product, engineering, and culture as we grow. You might know a lot about AI, machine learning and the financial industry, or very little—we will meet you where you are.

About you

• You want to be one of the first hires at an early-stage startup. You want to make a significant impact on hard problems. You might even dream of starting your own company one day.

• You are self-motivated and a completionist. Given a goal, you move fast, manage tradeoffs well, and communicate when plans change.
