Job description

Senior Embedded Firmware Engineer

Permanent ¦¦ Hybrid (4 Days Onsite) ¦¦ Shannon, Co. Clare

TechHeads is currently seeking an experienced Senior Embedded Software Design & Verification Engineer to design, develop and verify low-level embedded software for advanced electronic control systems operating within a highly regulated environment.

This is a hands-on engineering role suited to someone who enjoys working close to the hardware, developing efficient bare-metal software and supporting projects from concept through to verification and delivery. While this is a senior technical position, the focus is on technical mentorship rather than people management.

Responsibilities

• Design, develop and verify embedded software for safety-critical electronic systems
• Develop efficient, reliable bare-metal firmware in C for microcontroller-based platforms
• Work closely with hardware engineers to bring up new boards and support hardware integration
• Produce low-level drivers and interface software for peripherals and communication buses
• Support software architecture, requirements capture and detailed technical design
• Plan and coordinate technical activities across the software lifecycle, ensuring delivery against project milestones
• Estimate work packages, identify technical risks and provide regular project progress updates
• Support software planning documentation (e.g. PSAC, SDP, SAS) where applicable
• Perform software integration, debugging and system verification using HIL/SIL and hardware test environments
• Participate in design reviews, code reviews and requirements reviews
• Ensure software is developed in accordance with DO-178C and other applicable aerospace standards
• Mentor and support junior engineers through technical guidance, design discussions and code reviews
• Work collaboratively with systems, electronics, verification and project teams to ensure successful project delivery

Essential Requirements

• Strong commercial experience developing embedded software in C
• Excellent understanding of bare-metal embedded development with minimal or no RTOS abstraction

Strong knowledge of:

• Microcontroller architecture
• Memory management
• Interrupt handling
• Bootloaders
• Experience with ARM Cortex-M or similar microcontroller architectures
• Experience developing low-level device drivers and hardware abstraction layers
• Strong understanding of communication interfaces including SPI, I2C, UART and CAN
• Strong debugging experience using embedded development tools
• Experience with software verification and validation within regulated environments
• Experience with HIL/SIL testing and embedded system integration
• Ability to plan technical work, manage priorities and contribute to successful project delivery
• Excellent communication skills with the ability to collaborate effectively across multidisciplinary engineering teams

Desirable

• Experience with digital signal processing or motor control applications
• Exposure to MATLAB/Simulink or other modelling tools
• Familiarity with requirements management tools such as IBM DOORS
• Knowledge of version control, CI/CD pipelines and automated embedded testing
• Experience supporting DO-178C or equivalent safety-critical development standards

Qualifications

• Bachelor's degree in Electrical Engineering, Electronic Engineering, Computer Engineering, Embedded Systems or a related discipline
• 7+ years' experience developing and verifying embedded software in a commercial environment
• Demonstrated experience mentoring less experienced engineers and contributing to the successful delivery of complex embedded software projects
