We are seeking a hands‑on, innovative Electrical & Firmware Engineer who is excited to work in a fast‑paced R&D environment and contribute to the development of next‑generation engine control systems.

The Electrical & Firmware Engineer will be responsible for end‑to‑end development of embedded control systems supporting LiquidPiston’s advanced engine platforms. The ideal candidate is a strong C programmer with deep experience on TI C2000 microcontrollers, capable of designing, implementing, and validating both hardware and firmware components. This role involves multidisciplinary collaboration and requires a self‑driven engineer comfortable working individually and in small teams.

Key Responsibilities

• Develop, implement, and optimize embedded firmware primarily in C for TI C2000 Series microcontrollers.
• Design and maintain control system architectures, including discrete and analog I/O, signal conditioning, PWM generation, and closed‑loop PID control.
• Create custom display and user interface solutions for character and graphical screens.
• Implement and troubleshoot communication protocols including CANbus, SPI, I2C, and RS‑232.
• Support design and testing of power electronics control systems, including exposure to four‑quadrant motor control and space vector modulation.
• Design, prototype, and debug analog and digital circuits; support PCB design using tools such as Altium or OrCAD.
• Conduct hands‑on testing using oscilloscopes, multimeters, power supplies, and other lab equipment.
• Document firmware, test results, and system architectures clearly and thoroughly; prepare presentations as needed.
• Collaborate with mechanical, electrical, and test engineers on engine, ECU, and control system development.
• Support continuous improvement, rapid prototyping, and integration of new technologies into control platforms.

Required Qualifications

• Bachelor’s degree in Electrical Engineering, Computer Engineering, or related field.
• Strong proficiency in C programming and embedded firmware development.
• Hands‑on experience with TI C2000 microcontrollers.
• Familiarity with discrete and analog I/O systems, signal conditioning, PWM, and closed‑loop control.
• Working knowledge of CANbus, SPI, I2C, and RS‑232 protocols.
• Strong analog and digital circuit design and troubleshooting skills.
• Proficiency with common lab/test equipment (oscilloscopes, multimeters, power supplies).
• Excellent verbal and written communication skills, including ability to clearly document and present technical work.
• Proficiency with MS Office.

Benefits:

• Flexible PTO to encourage work‑life balance and personal well‑being
• Comprehensive healthcare coverage: medical, dental, and vision plans
• Equity participation: RSUs for all permanent employees
• 401(k) with match: 100% up to 3%, plus 50% match for 3–5% range
• Growth opportunities: Mentorship, training, and leadership development
