Senior Cloud/Backend Engineer

What Do We Do? Triple Whale is the AI operating system for e-commerce. More than 65,000 brands, including Kitsch, OUAI and True Classic, use it to measure what drives their business and act on it. We bring in data from every system a brand runs on their store, ad platforms, email, inventory and our own pixel. We model it into one measurement layer they can trust. On top of that sits Moby, our AI agent platform, which reasons over that data and takes action: it pauses ads, generates creative and raises inventory risks - he is managing your store for you. Behind that is a lot of infrastructure. We run hundreds of services on GCP and Kubernetes. Thousands of third-party integrations sync on a schedule. A wharehouse answers analytics queries in real time and AI agents orchestrate all of this at scale for the customers. All of it has to stay fast, cheap and secure while traffic jumps several times over during peaks like Black Friday. We get technologies to the edge.
