Overview

We are looking for senior software engineers focusing on the backend to join the Bastion engineering team.

We are mostly based in New York, but are open to amazing engineers anywhere in the United States as long as you are effective working remotely.

Instead of a list of requirements, we want to give you a directional look into the first 30, 90, and 180 days on the job.

We are a startup, so the pace is fast and the specific work will change. You need to be okay with that.

If you think this is something you can handle, we will be excited to speak with you.
