• Contribute to functional safety strategy and compliance efforts (ISO 26262, IEC 61508, etc.)
• Communicate technical status and risks to the engineering team and leads

Qualifications You'll Bring

• 5+ years of professional embedded software development experience
• Strong experience defining software architecture using object-oriented principles
• Deep understanding of embedded C++ toolchains (build systems, compilers, debugging environments)
• Strong experience developing production-quality software in Modern C++
• Deep understanding of microcontroller architecture and real-time operating systems
• Experience leading technical efforts or serving as subsystem owner
• Strong systems integration experience (sensor integration, actuator control, power control, etc.)
• Experience debugging using oscilloscopes, logic analyzers, signal analysis tools, and power supplies
• Solid understanding of electronics fundamentals and electrical calculations

What Makes You Stand Out

• Experience working with electric vehicle powertrains
• Strong familiarity with BMS systems and SOX algorithm development
• Experience with functional safety standards (ISO 26262, IEC 61508, ISO 13849)
• Experience mentoring engineers or leading small technical teams
• Experience interfacing directly with customers in technical capacity
