We are seeking a Firmware Validation Engineer to join a long-term embedded systems programme supporting a global access control leader. The role covers BLE, Wi-Fi, and wired-protocol IoT devices across a portfolio spanning legacy hardware (10+ years of shipped devices) and new product development. Hands-on hardware lab work, security validation, and multi-platform testing — and can context-switch efficiently across chipset families including TI, Nordic, STMicro, Renesas, and Silicon Labs. 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 Languages & Frameworks Python —robust experience in programming with Python and preferably in test automation scripts. C/C++ — test harness and driver-level work Experience in firmware development using FreeRTOS, TI RTOS — task scheduling and interrupt handling concepts Wireless & Connectivity BLE — GATT, GAP, pairing, bonding, advertising Wi-Fi 802.11 — provisioning, roaming, co-existence testing MQTT, Matter — protocol-level validation experience SPI, I2C, UART — wired protocol debugging with logic analysers Hardware & Debug Tools Hands-on experience with TI, Nordic Semiconductor, STMicro, Renesas, or Silicon Labs platforms JTAG/SWD debuggers, logic analysers, BLE sniffers, Wireshark MCUboot, TI OAD — OTA and bootloader validation GCC, TI Clang toolchains
