Linux Systems Engineer

9elements is the leading open-source firmware vendor in the world. Our engineers deliver production-grade open-source firmware for millions of servers everyday - and we are dedicated to open-source! We love being part of the community and we understand our responsibility to shape and drive the whole ecosystem forward!

Linux is at the heart of modern infrastructure - from the smallest embedded device to the largest data center fleet. At 9elements we help our customers build secure, trustworthy platforms based on open-source Linux stacks - from the firmware up. Whether it's hardening a Linux-based bootloader, integrating measured boot, or bringing a hypervisor to a new platform, we make sure open-source becomes the secure foundation that the industry can rely on.

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.

You are open-source at the heart. 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.

We love open-source and we want you! We think our employees are our biggest benefit that we have compared to the rest of the industry. We will try to make everything possible so that we can craft the job that you need to be happy.

As part of this role you will be working with some top-notch industry experts in the open-source systems and firmware field. We know how important open-source work is and we reserve time within your work time to interact with the community, review patches and be part of working groups. Every employee at 9elements also gets the chance to:
 
- 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.
