Senior/Staff Full Stack Engineer
About the role
About Ethos
Ethos is on a mission to bridge the human readiness gap by transforming how training is developed, consumed, and aligned with strategic business outcomes. As a well-funded Series A startup ($40M+ raised), we're a trusted partner to 150+ enterprise customers across the U.S. military, life sciences, manufacturing, supply chain, and professional sports.
We're expanding our engineering team to deliver a best-in-class learning platform—smarter, faster, and more optimized. We've gone all-in on AI tooling in our development process, and we're accepting and expanding upon the best new practices for creating software in this era.
About the Role
This is a backend-leaning full stack role. You'll work across Go backend services and React/TypeScript frontend, to continue modernizing our platform in an AI-friendly architecture. We're looking for engineers who treat AI tools as integral to their workflow, and as force multipliers that fundamentally change how software gets built.
As a Senior engineer, you'll own end-to-end feature delivery across the stack and shape architecture. As a Staff engineer, you'll also be a key leader on our team, guiding others and driving technical strategy.
