About The Position

We are seeking a Senior Firmware Engineer who will serve as a high-impact technical contributor within our Engineering & Test team. This position is ideal for an experienced embedded systems professional who combines deep hands-on development expertise with strong architectural thinking and cross-functional collaboration skills.

This role goes beyond feature implementation. You will help shape firmware architecture, influence hardware/software integration decisions, anticipate technical risks, and elevate engineering standards across embedded products. You will be expected to operate with a high degree of autonomy, take ownership of complex firmware initiatives, and contribute meaningfully to long-term product reliability and scalability.

The ideal candidate is a strong systems thinker who understands how firmware, hardware, and product requirements intersect and can proactively guide development efforts to deliver stable, production-ready solutions.

Requirements

• Bachelor’s degree in Electrical Engineering, Computer Science, or a related field required.
• A minimum of 5 years of progressive experience in embedded systems development required.
• Advanced proficiency in embedded C/C++ programming required.
• Strong experience developing firmware within RTOS environments and real-time systems required.
• Demonstrated expertise in hardware/software integration and low-level debugging required.
• Proven ability to independently own firmware components from concept through production required.
• Strong analytical, troubleshooting, and communication skills required.

Nice To Haves

• Experience working with microcontroller platforms such as Renesas, MSP430, Nordic, or similar preferred.
• Experience implementing communication protocols including I2C, SPI, UART, USB, and Bluetooth preferred.

• Knowledge of cellular communication technologies such as GSM, LTE, CDMA, and RS485 preferred.
• Familiarity with Agile development methodologies and tools such as JIRA and SVN preferred.
• Exposure to higher-level languages such as Python, Java, or C# for tooling, test automation, or system integration preferred.
• Experience in regulated, safety-sensitive, or hardware-centric product environments preferred.

Responsibilities

• Design, develop, and maintain embedded software and device drivers using C/C++ for production hardware systems.
• Architect and enhance firmware for real-time systems using RTOS environments, state machines, and event-driven design patterns.
• Lead development of communication interfaces including I2C, SPI, UART, USB, Bluetooth, and other wired/wireless protocols.
• Develop and optimize software for displays, sensors, control systems, and closed-loop systems such as PID controllers.
• Interpret schematics, datasheets, and hardware specifications to drive low-level software implementation and hardware/software integration decisions.
• Utilize lab equipment (oscilloscopes, logic analyzers, multimeters, etc.) to perform advanced debugging, validation, and root cause analysis.
• Collaborate closely with hardware, firmware, and application teams to integrate new features and ensure system-level reliability.
• Identify architectural improvements, technical debt, and performance constraints, and proactively implement scalable solutions.
• Contribute to development planning by forecasting technical challenges, hardware dependencies, and resource needs.
• Document firmware architecture, workflows, and design decisions using modeling tools such as UML, sequence diagrams, and flowcharts.
• Implement and advocate for best practices in code quality, static analysis, environmental testing, and secure embedded development.
• Serve as a senior technical resource within the team, elevating engineering standards through code reviews, mentorship, and design input.

Benefits

• A comprehensive health plan that includes medical, dental, and vision coverage to ensure you and your family have access to the care you need
• A 401(k)-retirement plan with a generous company match to help you save for your future and achieve your financial goals
