Overview

We seek a highly skilled and technically capable Senior Embedded Linux Software engineer (security focused) to join the Linaro Professional Services team. Applicants should have a proven record of developing and delivering system software for production-grade consumer electronics and industrial IoT devices. As an experienced senior developer, you will cover the role of a technical leader in customer projects, developing end-to-end operating system (Yocto/OpenEmbedded/Debian) support, bringing up BSPs for devices, and serving as firmware, kernel and OS, embedded security technical expert on the project.

A successful candidate will develop, support, maintain, and document software functionality; identify and evaluate new technologies for implementation; analyze code to find causes of errors and revise programs as needed; participate in software design and analyze user needs to determine technical requirements; and consult with the end user to prototype, refine, test, and debug programs to meet needs. Requires expert skill set, proficiency, and a proven record of open-source contributions.

Main Duties

• Design and development of custom operating system solutions based on Yocto, Android, and/or Debian platforms.

• Enable Linux support for various hardware blocks

• Strong knowledge of ARM SoCs and hardware security features, with particular emphasis on NXP i.MX SoCs.

• Bring up hardware platforms from scratch.

• Threat model and security hardening of embedded systems from firmware to OS.

• Enable and test end-to-end use cases on new platforms.

• Provide technical support and implement bug fixes.

• Provide technical leadership in your areas of expertise for the project. Influence others, including through engineering best practices and/or specialist knowledge.

• Drive forward significant features or improvements and increase the quality of the product.

• Collaborate within a team and with the upstream community.

• Presence and talks at open-source conferences.

Key Technical Skills & Experience

• Minimum five years of relevant practical experience working with production-grade embedded Linux (Yocto/Debian or Android) for Embedded/Consumer Electronics/IIoT Devices.

• Minimum of 5+ years of Embedded Linux experience, including SoC bring-up, BSP upgrades, platform security hardening or Secure boot (measure boot), remote attestation and linux security internals.

• Understand ARM CPU ISA & microarchitecture and experience of developing secure firmware on TrustZone, Trusted firmware - A/M or OP-TEE or equivalent secure OS.

• Experience with full boot chain and bootloaders like U-Boot, GRUB, and UEFI security hardening to establish root of trust on NXP i.MX series SoC.

• Good knowledge with applied cryptography.

• Familiar with OS image generation (Yocto/Debian or AOSP), packaging, release methodology, upgrades and updates, CVEs tracking and fixing, and CI/CD

• Participated in upstreaming of Linux projects like Linux kernel or maintaining open source projects is highly desired

• Knowledge of hardware protocols such as USB, PCIe, UART, I2C, SPI, and GPIO, as well as prior experience with Bluetooth and wireless technologies, is a plus.

• Hands-on experience with embedded hardware and software debugging using PC software tools, oscilloscopes, logic analyzers, etc…

• Track record of open source contributions to Linux kernel, userspace, or open source projects in general

Desirable Skills & Experience

• Familiarity with NXP iMX series (eg. iMX8xx & iMX9x) SoCs and internal architecture of different IP blocks especially security subsystem, how to securely provisioning SoCs for production

• Experience in enabling end-to-end security hardening solutions, eg. hardware assisted user data protection.

• Active Linux kernel developers or maintainers, particularly NXP SoCs.

• Published in open source forums, blogs, articles, etc

• Ideal candidates for this role would be curious, dependable, and adaptable, as well as pragmatic and capable of outreach.
