Are you a highly experienced Software Engineer with a passion for secure firmware? This role offers the chance to work fully remotely, collaborating with some of the most skilled engineers on a global scale.

Imagine being part of a world-leading Consumer Electronics company renowned for its innovation and excellence. This organisation is expanding rapidly due to significant demand and growth from its clients, backed by excellent financial support.

In this role, you will have the chance to develop, maintain, and optimise ARM Trusted Firmware (TF-A), U-Boot, and secure boot implementations. You will also be responsible for developing and maintaining trusted execution environments using OP-TEE. Your expertise will be crucial in integrating and enhancing security features in the Linux kernel, including secure boot flows, cryptographic frameworks, and access control mechanisms.

Your day-to-day responsibilities will include:

1. Debugging and analysing security vulnerabilities, applying patches, and implementing mitigations to enhance system security.
2. Collaborating closely with hardware, security, and software teams to define secure boot and firmware update strategies.
3. Contributing to upstream open-source projects related to firmware, bootloaders, security, and the Linux kernel.
4. Providing technical documentation and guidance on security best practices for internal and external teams.

To be successful in this role, you should have:

1. Extensive experience in software engineering with a strong background in secure firmware.
2. Proficiency in developing, maintaining, and optimising ARM Trusted Firmware (TF-A), U-Boot, and secure boot implementations.
3. Experience with trusted execution environments using OP-TEE.
4. A solid understanding of integrating and enhancing security features in the Linux kernel.
5. Strong debugging and analytical skills for addressing security vulnerabilities.
6. Experience with Git for version control.

Core skills include:

1. Hands-on experience with systems based on Arm architecture.
2. Strong experience with ARM Trusted Firmware (TF-A), U-Boot, secure boot, OP-TEE, and Linux kernel development.
3. Deep understanding of secure boot flows, firmware signing, key management, and cryptographic protocols.
4. Proficiency in C programming.
5. Experience with Yocto/OpenEmbedded, Buildroot, or other embedded systems.
6. Hands-on experience debugging low-level firmware issues using tools such as JTAG, GDB, and tracing.
7. Familiarity with secure firmware update mechanisms (e.g., A/B updates, rollback protection).
8. Excellent organizational skills.
9. Strong English language communication skills.
10. Ability to be productive in a globally distributed team through self-discipline and self-motivation, delivering according to a schedule.

This is a unique chance to work on security-critical components for ARM Trusted Firmware (TF-A), U-Boot secure boot OP-TEE, and the Linux Kernel for Embedded Platforms. If you are passionate about secure firmware and want to work with a globally renowned company, this role could be the perfect fit for you.
