Lead Controls & Firmware Engineer (Austin, TX)

Controls (PLC Path)

Develop and test PLC programs (Siemens, Rockwell, or equivalent) for system,

module, and site-level controllers.

Implement safety interlocks, alarms, and operational sequences for energy storage

modules.

Configure and validate industrial communication protocols (Profinet, Ethernet/IP,

OPC UA, DNP3, MQTT).

Integrate different system components with Microcontroller based devices.

Set up and maintain a test bench / HIL environment for PLC validation.

Firmware (Microcontroller Path)

Design and implement embedded firmware in C/C++ (Rust optional) for

microcontrollers if we migrate from PLC-based controls.

Develop and test communication stacks, device drivers, and OTA update

mechanisms.

Ensure deterministic, real-time operation in power and energy storage applications.

Set up and maintain a test bench / HIL environment for validation.

DevOps & CI/CD

Build and maintain CI/CD pipelines (GitHub Actions or similar) for PLC code, firmware,

and test automation.

Implement version control best practices for branching, releases, and tagging

safety-critical builds.

Develop infrastructure to run automated test suites including regression, simulation,

and hardware-in-the-loop.

Energy Storage Integration

Apply knowledge of utility-scale energy storage systems (battery management, PCS

interfaces, dispatch logic).

Participate in the development of control panel design for various components of energy

storage system.

Design & develop EMS/SCADA application to map controls data into historians, HMIs,

and cloud telemetry systems for monitoring & management of the system.

Support system integration, commissioning, and field validation.
