Experience in a regulated industry (medical, automotive, or aerospace) is preferred., * Strong proficiency in C/C++ on resource-constrained embedded targets. * Hands-on microcontroller and SoC development on ARM-based architectures, such as NXP i.MX processors and ARM Cortex-M4 microcontrollers. * Board bring-up and hardware debugging with oscilloscopes, logic analyzers, and JTAG/SWD debuggers. * Solid command of low-level I/O and serial protocols (I2C, SPI, UART, USB, GPIO). * Working knowledge of embedded Linux internals, including the kernel, device drivers, device trees, and board support packages, and/or real-time and bare-metal firmware. * Experience with a Yocto build environment; Buildroot or PetaLinux also applicable. * Ability to read schematics and datasheets and determine whether an issue is rooted in hardware, firmware, or software. * Proficient in source code management and CI workflows (e.g., Git and GitLab), with scripting in Python or Bash. * Familiarity with wired and wireless connectivity, including TCP/IP, Wi-Fi, Bluetooth/BLE, and 5G. * Familiarity with medical device standards and lifecycle processes (IEC 62304, ISO 14971, ISO 13485, IEC 60601) is preferred. * Experience ordemonstratedability to work in middleware and user-space components, includinginterprocesscommunication, service design, and system-level integration on embedded Linux is preferred. * Clear communication and disciplined documentation habits, which matter in a regulated environment. -Or- An equivalent competency level acquired through a variation of these qualifications may be considered. ## Description The role spans the firmware stack: embedded Linux on NXP i.MX processors and low-level firmware on the NXP ARM Cortex-M4 microcontrollers used in current TBCT designs. The Firmware Engineer delivers firmware for products in the field today and helps advance future platform generations built around more capable processors and emerging on-chip technologies. The firmware produced in this role directly shapes device reliability, performance, and compliance with medical device quality and regulatory standards. Collaboration is central to the role. The Firmware Engineer works closely with Electrical Engineering, Systems Engineering, Software, DevOps, and Quality to bring up new hardware, integrate firmware into the larger system, and turn product requirements into testable, verifiable firmware that performs dependably in the field., * Own board bring-up on new and revised hardware, verifying power sequencing, clocks, memory, and peripherals on the first boards and working with Electrical Engineering to contribute to architecture/schematic reviews, board bring-up, and resolving hardware and firmware issues. * Write, port, and debug device drivers and low-level interfaces (I2C, SPI, UART, USB, GPIO, ADC/DAC, PWM, DMA) for on-board sensors, actuators, and communication peripherals. * Develop firmware for the control systems that operate physical hardware such as motors, valves, pumps, and heaters, including real-time, timing-sensitive control loops. * Develop and maintain the embedded Linux stack on NXP i.MX platforms, including board support packages, device trees, kernel configuration, operating system integration, and userspace services, within a Yocto build environment. * Help evaluate and choose microcontroller architectures for future platforms, including parts with advanced on-chip processing capabilities, by building prototypes, benchmarking performance and power, and writing up the trade-offs. * Optimize firmware for speed, memory footprint, and power on resource-constrained targets. * Develop and maintain bootloaders, secure boot, and firmware update paths so devices start reliably and stay current in the field. * Translate system and product requirements into firmware designs, and produce the design documentation required by regulatory and quality processes (IEC 62304, ISO 14971, ISO 13485). * Plan and execute firmware verification and validation, and resolve issues found in development, integration, and the field. Create and execute automated unit tests, integration tests, and hardware-in-the-loop (HIL) testing. * Participate in and lead code and design reviews, and mentor engineers earlier in their careers. * Participate in software risk assessments, hazard analyses, SWFMEA and implement cybersecurity principles for connected devices * Partner with Systems, Electrical, Mechanical, and Quality Engineering across the full product lifecycle, from first prototype through production., * Help improve firmware development and test processes so they meet industry standards and internal benchmarks, and support inspection readiness with clear documentation and traceability. * Keep firmware maintainable, reusable, and scalable so it integrates cleanly across projects and platforms. * Stay current with embedded tools, techniques, and security practices, and bring useful improvements back to the team., Hybrid position reporting to the Lakewood, CO headquarters a minimum of 3 days a week. ## Related Videos - [Prototyping with Hardware and the Web](https://www.wearedevelopers.com/videos/651-prototyping-with-hardware-and-the-web) - [Blueprints for Success: Steering a Global Data & AI Architecture](https://www.wearedevelopers.com/videos/1577-blueprints-for-success-steering-a-global-data-ai-architecture) - [How a Small Team Shrank a Microsoft Monorepo by 94%](https://www.wearedevelopers.com/videos/1236-how-a-small-team-shrank-a-microsoft-monorepo-by-94) - [From Bedside Beeps to Interoperable Bytes – Getting your medical devices ready to talk the IEEE 11073 language](https://www.wearedevelopers.com/videos/771-from-bedside-beeps-to-interoperable-bytes-getting-your-medical-devices-ready-to-talk-the-ieee-11073-language) - [Project Fugu: Extending the web](https://www.wearedevelopers.com/videos/832-project-fugu-extending-the-web) - [Git for Code Reviews](https://www.wearedevelopers.com/videos/429-git-for-code-reviews) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Where to Find Entry-Level Software Engineering Jobs](https://www.wearedevelopers.com/magazine/397-where-to-find-entry-level-software-engineering-jobs) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [Is Software Engineering Hard?](https://www.wearedevelopers.com/magazine/448-is-software-engineering-hard)
