Professional Summary
Lead Embedded Software Engineer with 18 years of experience designing and delivering production Embedded C firmware for real-time, hardware-integrated automotive and industrial products. Strong hands-on experience on ARM Cortex-M and 8/16-bit PIC platforms, STM32CubeMX-driven HAL bring-up and Zephyr RTOS driver integration. Experienced in ISO 26262 functional-safety processes, ASIL-rated hazard reviews and supplier safety-requirement implementation for lighting and industrial modem programmes. Practised in embedded security (secure boot, mbedTLS, SHA-256), static analysis (Coverity/Black Duck) and CI/CD gated releases. Delivered firmware-level reliability and power optimisations, led threat modelling and vulnerability closure, and mentored engineering teams while owning V&V (HIL, lab-car, rig) and supplier coordination for shipped products.
Technical Skills
Work Experience
- Implemented driver- and peripheral-level firmware for adaptive driving beam, DRL and rear-lamp functions using Embedded C, delivering deterministic, interrupt-driven control for lamp peripherals.
- Operated within ISO 26262 functional-safety workflows to define safety goals, review lamp behaviour against ASIL-rated hazards and translate safety requirements into supplier software tasks.
- Owned verification and validation for supplier-released software; reviewed supplier test results and release notes and validated behaviour through rig-based and lab-car/HIL testing prior to sign-off.
- Diagnosed hardware-integration and firmware failures to root cause using schematic-level analysis and on-target debugging, then produced corrective firmware fixes and coordinated supplier implementation.
- Integrated LIN bus communication for lighting modules and validated inter-module messaging alongside existing CAN and serial protocol expertise to support vehicle network requirements.
- Evaluated supplier software quality using defect-rate and test-coverage criteria, feeding actionable findings into design and code reviews to raise release maturity and compliance.
- Architected cellular embedded system designs including component selection and multi-carrier reliability features, improving overall system reliability by ~20%.
- Led threat modelling and vulnerability assessment for connected products; prioritised findings with CVSS scoring and translated results into security requirements and mitigations, resolving 10+ high-risk vulnerabilities.
- Implemented secure boot and SHA-256 based firmware integrity verification and secure code-signing to harden device boot chains and enable authenticated firmware updates.
- Ran Coverity (Black Duck) static analysis on modem codebases, triaged and closed Major/Medium findings and validated fixes via development test-cases before gating through CI/CD.
- Authored design requirements, architecture documents and test procedures; mentored a team of engineers and directed design/code review cycles across internal and outsourced teams.
- Delivered a short-term onsite firmware design programme for a next-generation industrial cellular modem; implemented OTA capability and optimised interrupt/power-management logic to significantly reduce field power draw and improve serviceability.
- Developed board bring-up firmware and HAL-driven peripheral drivers on STM32 (ARM Cortex-M) using STM32CubeMX-generated code for a 4G LTE modem product.
- Implemented UART-based AT-command control for Telit ME910 cellular RF modules to enable SIM/network activation and TCP/IP connectivity for data transfer.
- Built Zephyr RTOS-based firmware for Cloudlink 5G using Nordic nRF9160 (Cortex-M33), implementing low-level device drivers and board support package integration.
- Wrote Python test scripts to accelerate bench validation and to integrate into CI/CD regression test workflows for modem firmware verification.
- Debugged issues across kernel, middleware and application layers during integration and validated RF module behaviour against vendor specifications.
- Partnered with hardware engineers on schematic-level bring-up and resolved cross-layer defects through targeted firmware fixes and test validation.
- Led rapid prototyping activities to validate embedded hardware/software concepts and translated results into proof-of-concept demonstrations for stakeholder review.
- Designed and implemented bare-metal firmware prototypes in Embedded C to evaluate peripheral performance and control strategies on target boards.
- Produced technical documentation and POC reports detailing design choices, test observations and recommended next steps for engineering teams.
- Integrated peripheral sensors and performed schematic-level debugging to demonstrate reliable data acquisition and control loops on prototype hardware.
- Developed test rigs and automated bench test scripts to reproduce and measure prototype performance under representative conditions.
- Presented prototype demonstrations to engineering leadership and captured feedback to prioritise feature maturation and potential productisation.
- Implemented closed-loop charge-control firmware for a 3.5kW battery charger using Embedded C; sampled voltage/current via ADC and regulated PWM duty on MOSFET switching stages.
- Applied moving-average and trimmed-mean (outlier-rejection) filtering algorithms to ADC samples to improve measurement stability for precise current regulation.
- Designed and tuned control loops that governed PWM-driven MOSFET switching to meet charge-profile requirements and thermal constraints.
- Produced SRS, design documents and test plans; coordinated hardware/firmware integration and executed system-level test procedures.
- Established CAN communication on the Phoenix programme, enabling in-vehicle diagnostics and signalling and earning Associate of the Month recognition.
- Partnered with test engineers to reproduce issues, close JIRA PARs and validate firmware fixes through bench and system testing.
- Prototyped firmware features in Embedded C to validate application interfaces and performance targets on evaluation hardware.
- Designed and documented clean APIs and module interfaces to simplify integration between application and middleware components.
- Performed schematic- and board-level debugging to isolate peripheral issues during bring-up and validation.
- Delivered integration test cases and participated in system validation to confirm feature readiness for release.
- Partnered with cross-functional engineers to translate product requirements into implementable firmware modules.
- Maintained prototype codebases and produced handover documentation to downstream engineering teams.
- Backed global customers on PIC microcontroller peripherals, toolchains and evaluation boards to accelerate time-to-market.
- Authored application notes and reference examples demonstrating peripheral configuration and common firmware patterns.
- Troubleshot customer designs at schematic and firmware level, diagnosing root causes and recommending corrective actions.
- Delivered technical trainings and demos on PIC architectures and development tools to internal and external stakeholders.
- Coordinated with product and QA teams to escalate customer issues and drive resolution of toolchain or silicon-related defects.
- Captured customer feedback and collaborated with engineering to enhance evaluation materials and documentation.
- Authored firmware design documents and specifications to guide implementation and ensure traceability to requirements.
- Developed embedded firmware modules in C and participated in hardware/firmware integration testing on target boards.
- Performed schematic review and debug to resolve peripheral-level issues during bring-up activities.
- Created and executed unit and integration test cases to validate firmware behaviour against specifications.
