Senior Firmware Engineer

GuRu Wireless Inc. is leading the innovation in high frequency RF wireless power transfer systems and is developing one of a kind long range wireless power solutions for UAVs. We are building a team of passionate thinkers and doers to support this vision. If you are highly motivated and interested in tackling the most challenging problems, we’d love to hear from you.  

GuRu has a highly talented, focused engineering team and is looking for a passionate senior firmware engineer with expertise in implementing real-time embedded systems. As a firmware engineer, you will play a crucial role in developing and optimizing embedded software for our innovative products. 

Responsibilities 

• Own firmware subsystems end-to-end, driving technical decisions on architecture, module decomposition, and interface design. 
• Design, develop, and maintain production-quality firmware for embedded systems using C. 
• Debug and optimize firmware for performance, reliability, power consumption, and real-time constraints. 
• Develop and maintain automated test frameworks, unit tests, and hardware-in-the-loop test infrastructure. 
• Manage source code using version control systems (e.g., Git) and champion best practices for branching, code review, and release workflows. 
• Document system and firmware behaviors, design rationale, and interface specifications for multidisciplinary teams. 
• Collaborate closely with hardware, systems, and applications engineers to ensure seamless firmware-hardware integration and to influence hardware design where firmware implications exist. 
• Contribute to technical roadmap planning and effort estimation for firmware deliverables. 

Necessary Qualifications 

• B.S. in Computer Science, Computer Engineering, Electrical Engineering, or equivalent industry experience. 
• 8+ years of professional experience developing firmware in C for embedded systems. 
• Strong understanding of real-time operating systems (RTOS) and their application in resource-constrained embedded environments. 
• Strong proficiency in C programming for embedded systems. 
• Deep knowledge of low-level hardware interfaces such as I2C, SPI, UART, and GPIO. 
• Proficiency in debugging embedded systems using tools such as JTAG/SWD debuggers, logic analyzers, and oscilloscopes. 
• Solid understanding of processor architectures, memory models, and the hardware fundamentals that embedded systems are built on. 
• Ability to diagnose and resolve complex issues spanning firmware, hardware, and system-level interactions. 
• Strong knowledge of software design principles including modularity, abstraction, and common design patterns. 
• Experience with version control systems (Git) and collaborative development workflows. 

Preferred Qualifications 

• Advanced degree (M.S. or Ph.D.) in Computer Science, Computer Engineering, Electrical Engineering, or a related field. 
• Experience with digital signal processing (DSP) algorithms and their embedded implementation. 
• Experience designing and tuning control loops (PID, state-space, or similar) in embedded real-time systems. 
• Proficiency in Python scripting for automation, testing, data analysis, or tooling. 
• Familiarity with wireless communication protocols such as Bluetooth (BLE), Wi-Fi, or Zigbee. 
• Knowledge of continuous integration / continuous delivery (CI/CD) pipelines and practices for firmware projects. 
• Experience with functional safety standards (e.g., IEC 61508, ISO 26262) or quality-regulated development environments. 
• Familiarity with Unix/Linux environments and cross-compilation toolchains. 
• Track record of mentoring engineers or leading small technical teams.
