Infrastructure Tech Lead

About the role

We're seeking an experienced infrastructure engineer to join us as a technical leader who will shape the future of our platform architecture! You'll work directly with our engineering leadership to drive infrastructure strategy, mentor our growing team, and build systems that scale with our ambitious growth plans. We recently raised a Series C and are experiencing rapid growth not just in the number of customers and users, but also in the kinds of data workflows we can support with our kernel compute backend.

This isn't a hands-off leadership role – you'll be deeply technical while providing strategic direction. We need someone who has strong opinions backed by experience and isn't afraid to make the hard decisions that come with rapid scaling.

• Experience with multi-region deployments and disaster recovery planning

Our stack

Our product is a web-based notebook and app authoring platform. Our frontend is built with Typescript and React, using a combination of Apollo GraphQL and Redux for managing application state and data. On the backend, we also use Typescript to power an Express/Apollo GraphQL server that interacts with Postgres, Redis, and Kubernetes to manage our database and Python kernels. Our backend is tightly integrated with our infrastructure and CI/CD, where we use a combination of Terraform, Helm, and AWS to deploy and maintain our stack.

In addition to our unique culture, Hex proudly offers a competitive total rewards package, including but not limited to, market-benched salary & equity, comprehensive health benefits, and flexible paid time off.
