Senior Security Engineer

Loft Orbital is revolutionizing access to space by building reliable, shareable satellites that drastically reduce the time and complexity traditionally required to get to orbit. We operate satellites, fly customer payloads, and handle entire missions from end-to-end. We’re a close-knit team of space enthusiasts, software experts, and cutting-edge technologists, all working together to make space simple for our customers.

As a Senior Security Engineer on our Security and Compliance Team, your mission will be to ensure that our highly automated, containerized, and globally distributed infrastructure remains secure throughout its lifecycle, from architecture to incident response.
