Exowatt is revolutionizing the energy landscape for the AI era with our groundbreaking P3 system that captures solar energy, stores it as heat, and generates electricity on demand.
Key Responsibilities
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.
Requirements
Bachelor’s in Electrical, Controls, Computer Engineering, or related field.
2–6 years of experience in PLC programming and/or embedded firmware development.
Proficiency with Siemens TIA Portal / Rockwell Studio 5000 (or similar).
Strong coding skills in C/C++ (Rust/Python a plus).
Experience with GitHub workflows, CI/CD pipelines, automated testing.
Familiarity with utility-scale energy systems or DERs.
Understanding of industrial networking and protocols (Profinet, Ethernet/IP, OPC UA,
DNP3, MQTT).
Exposure to energy storage standards (UL 9540, IEC 62443, IEC 61131-3, IEEE
1547).
Knowledge of cloud-integrated controls (AWS IoT Core, InfluxDB, Timestream,
CloudWatch).
Experience setting up test benches, simulators, or hardware-in-the-loop systems.
