ECU Software Flashing & Embedded Systems Engineer – Manufacturing Engineering

Job Description

Global Manufacturing Electrical & SDV is looking for innovators who thrive in tough challenges and are passionate about tackling meaningful work that will shape the future of the automotive industry. This isn’t a role for those looking for an easy path—it’s for those who embrace change, push through obstacles, and take ownership of complex problems. While there will be long days and moments that test your resilience, you’ll find purpose in your work, flexibility to prioritize your family, and the support of a people-first culture. If you’re ready to grow, thrive, and make a real impact, we’d love to hear from you.

Work Arrangement - Onsite

The successful candidate is expected to report to the Warren Tech Center on a full-time basis. This role requires up to 50% domestic and international travel.

WHY: The purpose of this role is to reduce vehicle yard holds, ensure product quality, and optimize the reflash process by designing, implementing, and deploying an ECU reflash solution across our manufacturing facilities. This role will be responsible for launching a productionized solution at each site and enabling successful startup and execution.

WHAT: As a reflash solutions engineer, you will build reflash hardware and software tooling solutions to program ECUs at the bench level then take it to GM production facilities.

HOW: Design, build, and deploy end-to-end ECU flashing and embedded tooling solutions—owning the full lifecycle from bench development through plant implementation, while working directly with manufacturing teams to troubleshoot issues, refine processes, and ensure reliable execution at scale.

This role is ideal for engineers with experience in ECU flashing, vehicle diagnostics, embedded systems, or manufacturing test environments who enjoy building and deploying solutions from lab to plant.

What You’ll Do (Responsibilities):

• Design and build hardware and software tooling to support programming of multiple ECUs.

• Execute ECU flashing activities across GM manufacturing sites.

• Collaborate with manufacturing, engineering, and suppliers to understand and improve current reflash processes.

• Develop and deliver training for new team members and contractors, and create clear, standardized documentation.

• Promote a safe work environment and ensure compliance with all company policies, procedures, and regulatory requirements.

• Foster a forward‑thinking work culture that embraces change and proactively addresses future organizational and industry challenges.

• Build and maintain strategic relationships across software, manufacturing, and program management teams to align efforts and drive future innovation.

Your Skills and Abilities (Required Qualifications):

• Hands-on experience with ECUs, embedded systems, or in-vehicle software programming/flashing.

• Experience designing or working with hardware/software tools used for ECU communication, diagnostics, or reprogramming.

• Strong understanding of automotive communication protocols (e.g., CAN, CAN FD, Ethernet).

• Experience using vehicle diagnostic and calibration tools (e.g., NeoVI, vSPY, DPS, or equivalent).

• Experience developing or supporting ECU reflash or software deployment workflows (bench or vehicle-level).

• Working knowledge of manufacturing and end-of-line (EOL) processes, including software flashing, validation, and issue resolution.

• Proven ability to troubleshoot software, hardware, and network interaction issues in vehicle or production environments.

• Experience collaborating across software, electrical engineering, and manufacturing teams to deliver integrated solutions.

• Willingness to travel (up to 50%) to support deployment across GM manufacturing sites.

What Could Give You a Competitive Edge (Preferred Qualifications)

• Experience developing custom reflash tooling (hardware interfaces, scripts, automation frameworks).

• Familiarity with software release processes, versioning, and breakpoint management.

• Experience working in vehicle assembly plants, launch environments, or manufacturing engineering.

• Understanding of SDV architecture and vehicle software integration in production environments.

• Experience creating standard work, technical documentation, or training materials.

• Exposure to automation, scripting, or data analysis (e.g., Python, test automation, logging tools).

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, or related technical field (or equivalent hands-on experience).



This role is categorized as onsite. This means the selected candidate is expected to report to a specific location on a full-time basis.

The selected candidate will be required to travel on a regular basis (25-50%) for this role.

This job may be eligible for relocation benefits.
