Responsibilities:

Wireless & Protocol Validation:

- Validate BLE (GATT, GAP, pairing/bonding) and Wi-Fi provisioning, roaming, and co-existence.

- Test MQTT delivery, QoS levels, and AWS IoT Core integration.

- Validate Matter commissioning and device interoperability.

- Verify SPI, I2C, UART driver behaviour and edge cases.

OTA & Bootloader:

- Validate OTA flows via MCUboot and TI OAD including rollback and interrupted update scenarios.

- Verify firmware signature checks and anti-rollback protections in the secure boot chain.

Security Validation:

- Test secure boot chain, TrustZone key storage, and secure element access controls.

- Execute anti-tamper scenarios and assess alignment with UL 2900 and NIST IoT guidelines.

Power & Performance:

- Measure power consumption across sleep, idle, active, and radio-on states.

- Validate battery life projections and RTOS task timing under load.

Hardware Lab & Automation:

- Execute tests on physical TI, Nordic, STM, Renesas, and Silicon Labs targets using JTAG/SWD and logic analysers.

- Capture BLE sniffer and Wireshark traces for protocol validation.

- Develop Python automation scripts integrated into Jenkins and AWS CodePipelines.

Requirements:
