Job description:

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 strong 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 Job Description

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 skilled 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.
