About The Company
EBR Systems, Inc. is driven to deliver superior treatment for millions of patients suffering from cardiac rhythm diseases by developing safe, clinically superior, cost-effective, and reliable therapies using wireless cardiac stimulation. The company’s initial product, the WiSE® CRT System, is a first-of-its-kind medical device developed to overcome the limitations of traditional Cardiac Resynchronization Therapy (CRT) in heart failure patients by eliminating the need for a lead to the heart’s left ventricle and the associated complications of that lead.

SUMMARY OF THE POSITION:

We are looking for a Sr. Firmware Engineer with experience in ARM-based microcontrollers and Bluetooth Low Energy (BLE) to help build the next generation of our connected hardware platform. In this role, you will design, optimize, and maintain embedded firmware that enables secure, reliable, real-time performance. 


You will collaborate with cross-functional partners in hardware engineering, product management, and QA to deliver high-quality features. 


In this role, you will not only contribute to foundational firmware components but also have the opportunity to pursue your long-term engineering ambitions. We foster an environment where personal dream achievements become part of the team’s shared success. 


ESSENTIAL AND OTHER DUTIES AND RESPONSIBILITIES: 

  • Design and implement embedded firmware for ARM Cortex-M and similar   microcontroller architectures. 
  • Develop and optimize BLE operation using vendor firmware stacks, and low-power firmware features. 
  • Build and maintain device drivers, hardware abstraction layers, and real-time components in C/C++. 
  • Establish a development platform based on IAR Workbench and Simplicity Studio, initially using vendor development boards and custom target boards. 
  • Debug complex hardware/firmware interactions using oscilloscopes, logic analyzers, and JTAG/SWD tools. 
  • Work closely with hardware teams on prototype firmware/hardware integration, firmware development, and system verification and validation. 
  • Implement power-efficient algorithms and low-power states for battery-operated systems. 
  • Participate in code reviews, design reviews, and documentation of firmware components. 
  • Support manufacturing, testing, and field diagnostics with robust tools and instrumentation. 
  • Influence the architectural direction of our embedded platform and contribute to long-term roadmap planning.
  • Other duties as assigned.  

QUALIFICATIONS:
