Description
We are seeking an experienced Firmware Validation Engineer to join a long-term embedded systems programme supporting a global leader in access control solutions.
The role focuses on validation and verification of BLE, Wi-Fi, wired-protocol, and IoT-enabled embedded devices, covering both a substantial portfolio of legacy products and recent product development.
The successful candidate will have strong hands-on experience in firmware and hardware validation, wireless and wired protocol testing, security validation, power and performance testing, and test automation. The role requires the ability to work effectively across multiple chipset and MCU platforms, including Texas Instruments (TI), Nordic Semiconductor, STMicroelectronics, Renesas, and Silicon Labs.
This is a hands-on engineering role suited to someone comfortable working in a hardware lab environment, debugging firmware-level issues, analysing protocol traces, and developing automated validation solutions.

Responsibilities
Validate Bluetooth Low Energy (BLE) functionality, including GATT, GAP, advertising,



pairing, bonding, and connection behaviour.
Perform Wi-Fi validation, including device provisioning, roaming, connectivity, and Wi-Fi/BLE coexistence scenarios.
Validate MQTT message delivery, QoS levels, reliability, and integration with AWS IoT Core.
Validate Matter device commissioning, connectivity, and interoperability.
Verify SPI, I2C, and UART drivers, interfaces, communication behaviour, and edge cases.
Validate firmware Over-the-Air (OTA) update flows using MCUboot and TI OAD, including interrupted updates, recovery, rollback, and failure scenarios.
Verify firmware signature validation, secure boot processes, and anti-rollback protections.
Perform security validation covering secure boot chains, TrustZone-based key storage, secure element access controls, and anti-tamper scenarios.
Assess product security implementation against applicable guidance and standards, including UL 2900 and N
