Mechatronics & Integration Engineer II

Job Description

Job Title: Mechatronics & Integration Engineer

Location: Folsom, California – USA

Time Type: Full Time

Nextpower is a global leader in intelligent solar tracker and software solutions, optimizing solar power plant performance worldwide. Within Nextpower, the Robotics and Autonomy team develops and deploys intelligent robotic systems operating in live solar environments. These systems combine mobility, perception, embedded compute, autonomy algorithms, and cloud intelligence to increase inspection capacity, improve safety, and scale operations.

We are seeking a Mechatronics & Integration Engineer to accelerate robotics development through rapid prototyping, system integration, testing, debugging, and deployment. This role sits at the intersection of mechanical engineering, electrical engineering, software, and robotics. You will work directly on robots, prototypes, engineering test systems, and field deployments, helping transform concepts into reliable, working systems. This role is based in Folsom, California and requires regular hands‑on work with robotic systems.

We move quickly and build real systems. This role is focused on turning ideas into working robots. You will work across mechanical, electrical, software, and robotics domains to rapidly prototype, integrate, test, and deploy new capabilities onto robotic platforms. The objective is to get them working quickly, learn from real‑world testing, and iterate. This hands‑on engineering role requires CAD, soldering, programming, debugging, and field work.

You will collaborate with autonomy, software, hardware engineers, technicians, and contractors to accelerate development and improve team velocity.
