Design, implement, and validate embedded firmware for resource-constrained devices (ARM Cortex-M) using C/C++/Rust and Zephyr. Develop device drivers, communication stacks (satellite, LTE, Bluetooth, mesh), optimize power and real-time performance, support board bring-up and hardware debugging, and build CI/CD and HIL test infrastructure.

Lead schematic capture, PCB layout, prototype bring-up and validation for small battery-powered consumer satellite-connected devices. Collaborate with RF, firmware, mechanical teams and vendors, design test fixtures and production test jigs, perform power analysis and optimizations, implement factory QA/automation, troubleshoot field hardware issues, and iterate engineering standards to bring features from concept to production.

Own end-to-end firmware QA for embedded satellite hardware: design and build HIL test rigs, automate regression suites with Python, correlate logs across debug probes and device interfaces, define release validation gates, and scale QA processes for hardware products.
