Job Title: Embedded Software Engineer (Firmware)
Job Description
This role focuses on designing, implementing, and delivering production-quality firmware for credential reader devices within an established embedded framework. You will independently own one or more subsystems, contribute hands-on code, and collaborate closely with other engineers to integrate cleanly into the existing architecture. The position emphasizes modern C++ development for microcontrollers, real-time performance on Cortex-M4F, and robust driver-level firmware for secure access and authentication products.
Responsibilities
+ Own the delivery of one or more embedded subsystems within the existing framework and credential reader application, from design through production release.
+ Design and implement components, threads, and modules in modern C++ (C++17 and above) using a defined Module/Thread/Component framework.
+ Implement ETL-based state machines and lifecycle hooks that meet hard real-time deadlines on Cortex-M4F microcontrollers.
+ Develop, extend, and harden Device Abstraction Layer drivers for STM32G474, including SPI, I2C, USB, UART, GPIO, timers, and DMA.
+ Extend and enhance the USB stack to support CCID and related functionality for secure credential readers.
+ Perform memory, timing, and power optimization, validating against budgets using static analysis, profiling tools, and on-target measurement.
+ Implement robust error handling, fault recovery, and safety-tolerant patterns consistent with a no-exceptions, no-heap-after-initialization policy.
+ Balance feature delivery with technical risk by making sound architectural decisions within an established framework without rewriting it.
+ Produce clean, maintainable code that meets established coding standards from the first day of engagement.
+ Collaborate with other embedded and firmware engineers to integrate new features and subsystems smoothly into the broader platform.
+ Validate firmware functionality through testing, debugging, and iteration to ensure reliable performance in production environments.
+ Contribute to the development of a new generation of secure NFC/RFID reader products by supporting key project milestones as a contracted engineer.
Essential Skills
+ Strong proficiency in modern C++ with experience in C++17 or later, and the ability to write high-quality, production-grade embedded code.
+ Minimum of 5 years of hands‑on firmware development experience focused on driver‑level and low‑level microcontroller programming (not application‑level development).
+ Demonstrated experience with real‑time operating systems (RTOS), with Zephyr RTOS highly preferred.
+ Practical experience developing firmware for microcontrollers, including Cortex‑M4F and STM32G474 or similar devices.
+ Strong understanding and practical experience with UART, USB, SPI, and I2C interfaces, with foundational to strong knowledge of USB as a core part of the work.
+ Experience implementing and maintaining Device Abstraction Layer drivers for peripherals such as SPI, I2C, USB, UART, GPIO, timers, and DMA.
+ Ability to implement ETL‑based state machines and lifecycle hooks that meet hard real‑time constraints.
+ Experience with memory, timing, and power optimization in embedded systems, including use of static analysis, profiling, and on-target measurement tools.
+ Proficiency in implementing error handling, fault recovery, and safety‑tolerant patterns under a no‑exceptions, no‑heap‑after‑init policy.
+ Good understanding of security concepts and secure firmware design, ideally ]]>
