Embedded Engineer

About the project

We build an embedded compute module around NXP i.MX8MP for real-time video capture, processing in a constrained field environment.

You will own the Linux stack: BSP, kernel, device tree, userspace services and the video/networking pipeline.

Responsibilities

• Maintain and extend the Linux BSP for NXP i.MX8MP (U-Boot, kernel, DT, low-level drivers).
• Bring up and debug new hardware revisions.
• Tune drivers / DT for CSI camera, I²C/SPI, GPIOs and storage.
• Improve boot performance, reliability and recovery.
• Maintain Yocto layers and recipes for a custom distribution.
• Add/patch third-party components (GStreamer, networking, debug tools).
• Design and maintain image update workflows (e.g. uuu, scripted updates, integrity checks).
• Ensure reproducible builds and clear separation of BSP vs application layers.
• Implement and debug GStreamer pipelines for CSI v4l2 capture, H.264 streaming and SD card recording.
• Integrate camera-adapter firmware update tools and ensure safe update procedures.
• Profile and optimize CPU/GPU/VPU load, memory bandwidth and latency.
• Design and maintain systemd services (recorder, monitoring, watchdogs).
• Handle power events, removable media and degraded conditions (I/O errors, low space, link loss).
• Add health monitoring, metrics and logging for field diagnostics.
• Configure and debug network links for throughput and latency.
• Integrate the compute module with other modules via UART and similar interfaces.
• Work with MCU/firmware developers on interfaces and update flows.
• Develop CLI tools and scripts (Bash/Python) for flashing, testing and diagnostics.
• Maintain concise technical documentation (bring-up, updates, troubleshooting).

Requirements

• Proven experience as an Embedded Linux engineer on real hardware.
• Strong C skills in a Linux/embedded environment (kernel or low-level userspace).
• Hands-on Yocto experience:
• Writing/modifying recipes and classes
• Maintaining custom layers
• Building and debugging board-specific images
• Experience with U-Boot and Linux kernel on ARM SoCs (preferably NXP i.MX).
• Confident with device tree (nodes, bindings, enabling peripherals).
• Practical GStreamer experience for capture/encode/stream pipelines.
• Solid systemd knowledge (units, targets, dependencies, journald, boot debugging).
• Confident with Linux CLI and debugging tools: dmesg, journalctl, strace, gdb, perf, etc.
• Basic hardware-level debugging (UART console, logic analyzer/oscilloscope).
• Ability to read schematics and understand SW—HW interactions (power, reset, muxing).
• Good written and spoken English for technical communication and documentation.

Nice to have

• Direct experience with NXP i.MX8MP or similar multimedia SoCs.
• Experience with wireless links in constrained/outdoor setups.
• Experience with OTA update frameworks such as swupdate, Mender or similar (A/B updates, rollback strategies).
• Exposure to UAV / robotics (MAVLink, UDP telemetry, etc.).
• Experience with OpenWrt, Armbian or other embedded Linux distributions.
• Python for tooling and data analysis (log parsing, small utilities).
• Experience with MCUs (STM32, etc.) and firmware updates from Linux host.
• Work on field-deployed systems with strong reliability and diagnostics requirements.

Personal profile

• Methodical and skeptical: you rely on measurements and logs rather than assumptions.
• Comfortable working end-to-end, from bootloader and kernel to services and scripts.
• Willing to take ownership of a complex embedded Linux platform and keep it robust, debuggable and maintainable.
