Connect user workflows to embedded services, control software, and physical hardware.
Make practical UI decisions using React and Material UI, partnering with the in-house designer as needed.
Work with Go, Python, gRPC, MQTT, and related messaging and service technologies.
Own features from requirements through implementation, testing, deployment, and field feedback.
Collaborate with software, firmware, electrical, mechanical, field, and test engineers.
Required
7+ years of professional software engineering experience.
Strong full-stack experience building and supporting production applications.

Ability to work across application, backend, integration, and deployment layers.
Strong ownership, initiative, and ability to make sound technical and UI decisions independently.
Experience with industrial controls, SCADA, energy storage, power systems, manufacturing, robotics, or other hardware-connected products.
Familiarity with OPC UA, Modbus, DNP3, CAN, or similar industrial protocols.
Experience integrating software with physical devices, sensors, or control systems.
