You will be working with our systems and security team on various customer projects.
The team size ranges between 2 to 5 engineers on one project.
You will design, harden and ship Linux-based system software
from kernel and userspace components to secure boot chains, TPM integration and attestation
always aligned (and upstreamed back) with/into the community.
Your mission is to shape the security of this ecosystem with us and break the ties to the proprietary world. 9elements and you have one mission: Change how we build secure systems and make open-source the standard for trustworthy computing.

(Embedded) Linux is your home turf
You're comfortable building, debugging and shipping Linux systems, from the kernel down to drivers and up through userspace, and you're not afraid to read source code (or write it).
You care about security
You think about threat models, attack surfaces and trust boundaries, and you want to make systems that are secure by design instead of secure by hope.
Being able to deep dive into technical issues
You love code and love debugging issues down to the core (which can be hardware
sometimes).
You're fluent in English
English is our business language, internal and external and you should be able to communicate with it.
You like working with Open-Source
sounds obvious but working with the open-source communities can be challenging sometimes. You have to be able to find the best possible solutions for our customers and the community.
Be engaged
At 9elements we help each other. Our mission is big: We transform the firmware industry
it takes dedication and team effort to tear down this ecosystem and build it up from scratch again.

Linux Kernel Development
Hypervisor experience
You've worked with KVM, Xen, or smaller research hypervisors and understand virtualization from the bare metal up? We'd love to hear from you.
Hands-on experience with TPMs, secure boot, measured boot or remote attestation.
Yocto, Buildroot or custom distro experience for embedded targets.
Low-level languages are your friends
C is a given, Rust is a plus.

Regularly visit industry conferences like OCP EMEA/Global Summit/Linux Plumbers or others
Be part of our own conference
the Open-Source Firmware Conference (https://www.osfc.io)
Choose your platform: Lenovo or Framework? We got you! You want to run Arch? Sure thing. Choose your platform where you can work best.
Full Remote: We are headquartered in Germany and all the hardware is in our labs here. You can be around the world
we enable you to fully develop remotely.
Your schedule: We need your work time to overlap a couple of hours with the German work time. Other than that
shape your work time as you need it to be as long as you get the job done.
