Please prioritize candidates with strong bare-metal embedded firmware experience. This is a key requirement for the client and will be a major factor in candidate selection.

Candidates whose backgrounds are primarily focused on Embedded Linux, application software, cloud development, or higher-level systems engineering without significant bare-metal firmware experience are less likely to match the client's requirements.

Position Summary

We are seeking a highly capable Senior Firmware Engineer with 8+ years of embedded firmware development experience to take ownership of product firmware, features, and firmware lifecycle execution across microcontroller-

based products. The ideal candidate is a hands-on engineer with solid software development discipline, deep bare-

metal firmware expertise, and proven ability to deliver robust production-ready firmware from concept through field support.

This role is best suited for an engineer who can independently define firmware architecture, develop features, debug hardware/software interaction issues, support validation and manufacturing, and drive long-term firmware maintainability. RTOS experience is a plus, but bare-metal embedded development is the primary focus.

Role Emphasis

This is not only a coding role. The successful candidate must own firmware outcomes: requirements clarification,

architecture decisions, implementation, validation, release readiness, field issue resolution, and ongoing product improvement.

Key Responsibilities

Firmware Ownership

 Own firmware architecture, design, implementation, verification, release, and maintenance for assigned products or product platforms.

 Take responsibility for firmware feature development, bug fixes, reliability improvements, and future roadmap enhancements.

 Translate product and system requirements into clear firmware designs, modules, interfaces, and testable deliverables.

 Drive technical decisions related to code structure, timing behavior, peripheral usage, communication interfaces,

diagnostics, and firmware upgrade strategy.

 Maintain firmware quality, readability, performance, and long-term serviceability across product generations.

Embedded Software Development

 Develop embedded firmware primarily in C / Embedded C, with C++ used where appropriate.

 Design and implement low-level drivers, hardware abstraction layers, control logic, state machines, bootloaders,

communication handlers, diagnostics, and fault handling.





 Apply strong software development practices including modular design, version control, code reviews,

documentation, defect tracking, and structured release discipline.

Senior Firmware Engineer

 Optimize firmware for memory usage, execution time, reliability, startup behavior, and deterministic real-time response on resource-constrained microcontrollers.

Hardware Integration & Debugging

 Support hardware bring-up, prototype validation, design verification, production launch, and field issue investigations.

 Debug firmware and hardware interaction issues using oscilloscopes, logic analyzers, protocol analyzers,

multimeters, signal generators, and JTAG/SWD debuggers.

 Analyze timing issues, peripheral behavior, communication failures, sensor/actuator interface problems,

interrupts, resets, watchdog events, and intermittent system faults.

 Collaborate closely with electrical, software, manufacturing, quality, product, and service teams to resolve technical issues quickly and systematically.

Verification, Release & Product Support

 Create and execute firmware test strategies, validation plans, bench-level test procedures, and regression checks.

 Support firmware release documentation, version control, build artifacts, release notes, and traceability from requirements to validation results.

 Participate in root-cause analysis, corrective actions, design reviews, field issue reviews, and manufacturing test improvement activities.

 Mentor junior and intermediate engineers on firmware design, debugging, coding practices, and product ownership behavior.

Required Qualifications

 Bachelor’s degree in Electrical Engineering, Computer Engineering, Software Engineering, Computer Science, or equivalent technical discipline.

 Minimum 8 years of professional embedded firmware development experience.

 Strong hands-on experience with bare-metal microcontroller firmware development.

 Proven experience taking product firmware or major firmware features from concept through production release and long-term maintenance.

 Demonstrated ability to debug complex firmware, hardware, timing, communication, and system-level issues.

 Strong understanding of embedded software design principles, structured coding practices, interface design,

testing discipline, and documentation.
