Firmware Engineer

About the Company:

Our mission, in a single line, is to help people live longer and healthier lives. This mission defines and guides everything we do and everything that we hope to do. Our aim is not only to expand lifespans, but more importantly, to expand health spans, by enabling people to live life of the quality that they desire.

Prior to the 21st century, the three traditional frontiers were considered to be land, sea and air. We believe that the most important frontier in the 21st century is the human body itself, and therefore the focus of our company is to look inwards, into the human body - which for us is the Fourth Frontier.

We have picked heart health as our primary focus area, since cardiovascular disease is the leading cause of mortality across the globe. Despite its importance, affordable products and services to monitor and improve heart health from the comfort of your home have not been available to consumers. Fourth Frontier is committed to solving this important problem.

Position summary

Fourth Frontier offers pioneering products and services for monitoring and improving heart health across the globe. As an embedded firmware engineer, you will design, implement and release firmware for low-power, resource-constrained projects. You will be responsible for developing and optimizing firmware using Zephyr RTOS with a strong focus on Bluetooth Low Energy (BLE) communication. You will also develop automation and manufacturing test applications, validate system designs with the hardware team, and use measurement tools for firmware verification. You will collaborate with various stakeholders to enhance system quality, reliability, security, and automation.

Key Areas of Responsibility:

The key responsibilities of this role will include:

• Participate in design, implementation, release, and debugging of embedded firmware to run on real-time operating systems.
• Architecting and maintaining firmware applications within the Zephyr RTOS, including board porting, device tree configuration and driver development.
• Develop firmware applications for automation tests and manufacturing tests.
• Work with the hardware team on system design validation and compliance.
• Use test and measurement apparatus, including oscilloscopes, logic analyzers, communication protocol analyzers, and signal generators, to ensure that firmware functions per design requirements.
• Interface with application owners, developers, QA, project managers, support teams and end users.

Essential skills, qualifications and experience:

• Experience: 4+ years of experience in embedded software development, with at least 2+ years of hands-on experience specifically with Zephyr RTOS.
• Qualifications: Bachelor's/Master's Degree in Electronics or Computer Science Engineering.
• Expert level Embedded C knowledge.
