About the Position

We're looking for Linux Engineers to join the team that maintains the critical infrastructure underlying the rest of Jane Street's technology. It's a broad role, and no two Linux Engineers look exactly alike.

You should expect to work in some (but not necessarily all) of these areas, and to go genuinely deep in a few.

That might mean:

• Building the in-house tools and systems that make up our platform, or integrating mainstream (often open-source) technologies so they feel native to our infrastructure
