Personal scope
What I owned
- Initiated the embedded BMS program and continued its integration after progressing to Engineer III.
- Connected monitoring, communication, diagnostics, and safety configuration across the firmware and hardware boundary.
- Supported system bring-up and issue investigation with observable state and diagnostic readback.
- Now provide technical guidance to junior engineers contributing to embedded implementation and validation.
Engineering approach
How I reasoned about it
- 1
Keep measurement, control, protection, and reporting responsibilities explicit so faults can be traced to the correct layer.
- 2
Make safety behavior configurable and visible rather than burying thresholds and state transitions in scattered code paths.
- 3
Treat bring-up as an interface problem: verify electrical behavior, device communication, firmware state, and host interpretation together.
Validation
How the signal was checked
- Interface and communication checks during board and system bring-up
- Diagnostic readback for system measurements, charge state, communication, and configured status
- Integrated-system validation of configurable safety behavior
