Description

As a Senior Software Engineer in Team Autopsy, you will build automation and optimization capabilities that help our customers save time, improve campaign performance, and reduce the manual work required to manage advertising campaigns at scale.

Team Autopsy owns several core services at the heart of the Smartly platform, including Triggers, Ad Rotation, Smartly Actions, and Action Router. These systems enable customers to automate campaign management, optimize advertising performance, and reliably execute changes across multiple media platforms.

Our technology stack includes TypeScript, Python, Node.js, NestJS, Koa, PostgreSQL, Redis, Kubernetes, Temporal and React. We are a data-heavy team and rely extensively on strong typing and shared TypeScript definitions that support development across Smartly.
