## About the Role

* Degree in Computer Science, Electrical/Electronic Engineering or a related field, or equivalent practical experience.
 * 5+ years of professional software development, with a substantial portion on embedded systems.
 * Expert knowledge of modern C++ (C++17/20) with memory and performance awareness on constrained systems.
 * Hands-on experience building and customising embedded Linux with the Yocto Project (layers, recipes, bbappends, SDKs, BSPs).
 * Practical experience designing APIs with Protocol Buffers and implementing gRPC services and clients.
 * Strong understanding of IPC mechanisms and concurrent, multi-process system design on Linux.
 * Demonstrable experience applying secure-by-design principles: secure boot, code signing, TLS/mTLS, and secure coding practices.
 * Firmware development for STM32 or comparable ARM Cortex-M microcontrollers, including RTOS usage, low-level peripheral work.
 * Comfortable with Git, CMake and/or Cargo, CI systems, and debugging tools., * Experience with robotics or software-defined / reconfigurable machines.
 * Experience in laboratory automation, chemistry, life sciences or other regulated industries (helpful but not required).
 * Experience with functional safety standards (IEC 61508, ISO 13849) and safety-aware software development.
 * Knowledge of cybersecurity standards and regulations.
 * Experience with fleet management and remote telemetry.

## Description

* Translate architecture requirements into robust, scalable and testable software.
 * Design, develop and maintain embedded software in C++, including inter-process communication (IPC) on Linux Yocto OS for Raspberry Pi and STM32 series microcontrollers.
 * Integrate with cloud and on-prem communication channels using communication protocols like gRPC, MQTT, HTTPS and others.
 * Implement over-the-air (OTA) update mechanisms (e.g. A/B partitioning with RAUC, SWUpdate or Mender) and rollback strategies.
 * Develop real-time firmware for STM32 MCUs in C++ and (bare-metal, FreeRTOS, Zephyr).
 * Work with peripherals and buses such as RS-485, RS232, UART, USB and Ethernet, including interrupt-driven designs.
 * Define and evolve interfaces using Protocol Buffers, with a disciplined approach to schema versioning and backward/forward compatibility.
 * Design and implement inter-process communication on the Linux side (e.g. Unix domain sockets, shared memory, message queues, with clear latency, throughput and isolation guarantees.
 * Design efficient, robust communication between the Linux host and MCUs, including framing, error detection, and compact serialisation (e.g. nanopb or similar).
 * Establish a hardware root of trust, secure boot, signed firmware and images, and secure key storage (TPM, secure element, TrustZone or STM32 security features).
 * Apply least privilege and process isolation (e.g. dedicated users, Linux capabilities, seccomp, namespaces, SELinux / AppArmor).
