Real-Time Firmware Engineer
About The Position
ConnectDER is seeking a Real-Time Firmware Engineer to work on challenging, meaningful problems at the intersection of hardware, software, and clean energy. This role involves building a new product from the ground up, contributing directly to firmware that powers electrification, grid resiliency, and distributed energy resources (DERs). The ideal candidate enjoys deep technical work, solving real-world problems, and seeing their code move from concept to deployed product. This is a full-time hybrid position requiring 3 days on-site at their Philadelphia office.
Requirements
- 5+ years experience as a Real-Time Firmware engineer designing, implementing, and testing embedded software/firmware for microcontrollers based products
- Professional experience developing software applications in C/C++
- Experience using RTOS to create software/firmware for multi-threaded, timing critical applications. Good understanding of timing budgets in critical systems
- Proficient with debugging/troubleshooting techniques, including JTAG Debuggers, trace analyzers, and use of electronics lab equipment such as Multimeters, Oscilloscopes, Logic analyzers, and Signal/Function Generators
- Professional experience using Source Control Management systems (e.g. Git)
- Understanding of static source code analysis tools/methods
- Experience in developing design documentation (requirements, flowcharts, data flow diagrams, state transition diagrams, etc.)
- Basic understanding of electronics concepts
- Must have the ability to work on a computer for extended periods of time with or without accommodation.
