Software Engineer - Systems

About SFC

At SFC, we are building a GPU market which necessitates bringing the software functionality of the hyperscalers to GPU neoclouds. The work in this role spans provisioning and monitoring bare metal servers with our VM orchestration software all the way to coordinating with our GPU marketplace to enable users to configure the VMs, networks, and storage running on their rented compute. Parts of this include building a Linux OS image with our software tools along with maintaining a tool to ensure that our golden image is able to be consistently (applied across nodes along with per-data-center tweaks such as networking configuration), and helping design the API protocol and server that users interact with in order to configure VMs.

We primarily use Rust as it enables us to write code that operates at almost every layer of our system (from the web server to coordinating with the kernel, and BIOS), but if you are familiar with a language that requires manual memory management (such as C) and have experience with a higher-level language then you would also be a great fit.
