Principal Software Engineer (Data Ingest Platform)

Are you the kind of engineer who gets more satisfaction from building a platform that makes other developers 10x more productive than you do from building a single product feature? Do you enjoy designing elegant frameworks and APIs that other engineers love to use? Do you see tough orchestration and scalability problems as puzzles waiting to be solved?

If you're nodding your head, we’re looking for a Principal Engineer to lead the technical vision and architecture of our Data Ingest Platform. This is more than just a job building pipelines; it's an opportunity to own the 'front door' for all the security data that fuels Expel’s services and to create a world-class developer experience for the engineers who build our hundreds of integrations.

At Expel, we’re on a mission to make security easy to understand, easy to use, and easy to continuously improve. The data that flows through our platform is the lifeblood of our security operations, and you’ll be at the heart of ensuring that flow is scalable, reliable, and efficient.
