We are looking for a Senior Embedded Software Engineer to develop firmware for our advanced VR/XR products on the Qualcomm and Android platform, working in an embedded environment. You have experience developing high quality software for resource-constrained systems. You have an understanding of electronics, and are able to navigate your way through schematics.

This is a highly technical space, and you will be working with some of the industry’s leading experts. You do not need to have a background in VR/XR, but you will need to show an interest and aptitude for bridging the gap between customers and deep technology. You can get into the detail of topics, but also to provide clear written and oral synthesis.

Experience building hardware products and/or products that require researching and inventing new technology is preferred. This position is based in Finland. Varjo uses hybrid work mode and you'll be able to choose either to work at the office or remotely. To effectively perform in this role, we expect that you will need to visit our Helsinki office whenever necessary to work with prototype hardware.

What you’ll be doing

• Android Platform Bring-up: Port and bring up Android (AOSP) on Qualcomm Snapdragon SoCs, including bootloader configuration, kernel integration, and device tree adaptation for new custom hardware.

• Embedded Software Development: Design, develop, and maintain low-level software for advanced embedded platforms, ensuring optimal performance on tightly constrained systems.

• Hardware Integration: Collaborate with hardware engineers to validate new boards, debug hardware/software interactions, and perform power/performance optimizations.

• Kernel & Driver Development: Customize and integrate Linux kernel drivers, board support packages (BSP), and HAL (Hardware Abstraction Layer) components.

• Debugging & Optimization: Use tools such as JTAG, serial console, and Android-specific debugging utilities to trace issues across the boot chain and runtime environment.

• Cross-Team Collaboration: Partner with other software teams to bridge the gap between hardware and software, ensuring cohesive system functionality.

• Production Support: Support manufacturing and production testing by providing reliable platform-level builds and diagnostics.

Our expectations

• 7+ years of software development experience, with 3–5 years focused on Android BSP, platform development, or AOSP bring-up on ARM/Qualcomm SoCs.

• Deep understanding of Android system architecture, from bootloader to framework.

• Strong experience with Linux kernel, device trees, and Qualcomm toolchains.

• Proven capability in debugging at multiple layers: bootloader, kernel, board initialization, and HAL.

• Proficiency with C/C++ and scripting (Python or Bash).

• Familiarity with Git, CI/CD, and embedded development toolchains.

• Experience with Yocto, U-Boot, or other embedded build systems is a plus.

• Exposure to XR/VR or multimedia pipelines on Android is advantageous.
