Senior Software Engineer

About the Team
Global Manufacturing IT delivers innovative technology solutions for GM's vehicle manufacturing plants worldwide.
Our EOL (End of Line) development team, based primarily in Dublin with additional support in the US, is responsible for multiple mission-critical applications, including the wiring harness tester solution.
Why Join Us
At GM, we are committed to our vision of
Zero Crashes, Zero Emissions, and Zero Congestion
.
We are shaping the future of mobility by advancing safety, sustainability, and continuous innovation.
About the Role
As a Senior Software Engineer, you will play a key role in the development and maintenance of multiple EOL applications.
You will lead hardware and software development for the
Low-Cost Continuity Tester (LCCT)
solution, evolving production firmware for ESP32-based microcontrollers to ensure reliable operations, secure provisioning, and seamless integration with enterprise systems.
Working closely with global stakeholders and suppliers, you will help bring solutions from concept to production in GM plants and approved supplier sites.
What You'll Do
Embedded Systems (LCCT/Continuity Tester):
Contribute to hardware design reviews and collaborate with internal and external teams on product iterations.
Design, implement, and maintain production-grade firmware in C/C++ for ESP32-based devices, covering board bring-up, drivers, and feature development.
Optimize FreeRTOS-based solutions across SPI, I2C, UART, GPIO, and memory/power management for manufacturing duty cycles.
Implement secure provisioning and configuration flows (barcode-based setup, APIM credentialing, key exchange via serial/USB) aligned to enterprise security standards.
Develop robust Wi-Fi networking and enterprise service integration (REST, message queues) with resilient error handling.
Enable observability with structured logging, metrics, and diagnostics; participate in on-call rotations supporting global plant operations.
Collaborate on API contracts, device state models, and secure endpoints; influence architecture for scalability and operability.
Ensure quality with unit/integration testing, hardware-in-the-loop validation, and CI/CD pipelines (GitHub Actions).
Document processes, propose improvements, and mentor peers in embedded standards and deployment practices.
Full Stack Applications (EOL Systems):
Lead end-to-end delivery of EOL applications, from requirements to production.
Develop scalable backend services using
Java Spring Boot
(REST APIs, data persistence, messaging/streaming integration).
Build and maintain
Angular front-end applications
(TypeScript, RxJS) with responsive, accessible, and performant UIs.
Establish observability across services and UIs (logging, metrics, tracing, SLOs, dashboards).
Apply security best practices (OWASP, OAuth2/OIDC, secrets management).
Drive coding standards, testing strategies, and design reviews; mentor engineers and guide architecture decisions.
Collaborate with product, UX, and manufacturing teams to prioritize features and de-risk deployments.
Optimize CI/CD workflows (quality gates, dependency scanning, release patterns such as blue/green or canary).
Troubleshoot complex issues spanning embedded devices, networks, backend services, and UIs.
Required Skills & Behaviors
6+ years
embedded software development (C/C++ on microcontrollers, RTOS, multithreading, hardware debugging).
3+ years
hands-on with ESP32 and ESP-IDF (board bring-up, drivers, Wi-Fi, NVS, SPI flash, OTA strategies).
6+ years
backend development with Java/Spring Boot (REST APIs, data persistence, production operations).
3+ years
front-end development with Angular/TypeScript/RxJS (testing, accessibility, performance).
Proven experience with secure device provisioning/configuration (serial/USB workflows).
Track record of delivery in manufacturing or mission-critical environments with strong diagnostics.
Experience with Git workflows and CI/CD pipelines for firmware and applications.
Solid foundation in software engineering best practices, agile methodologies, and cross-timezone collaboration.
Strong ownership mindset across the full device and application lifecycle.
Effective collaboration across firmware, backend, UI, platform, and manufacturing teams.
Clear communicator in technical proposals, design reviews, and plant-facing documentation.
Continuous learner who constructively challenges the status quo with data-driven insights.
Preferred Qualifications
Expertise in device security (encryption, secure boot, key management, secrets handling).
Familiarity with plant networks and resilient device connectivity patterns.
Experience with barcode/RFID peripherals and label/receipt printing.
Exposure to event-driven systems and real-time data processing (Kafka, MQTT).
Knowledge of IoT wireless technologies (LoRaWAN, RFID, BLE).
Experience with containerization/orchestration (Docker, Kubernetes).
Background in automated testing frameworks and BDD approaches.
Work Location & Schedule
Primary Locations:
Dublin or Limerick, Ireland
Hybrid -
This role is categorized as hybrid.
This means the successful candidate is expected to report to the Dublin/ Limerick office three times per week, at minimum.
Business hours aligned with EU/US time zones; occasional weekend/holiday support for deployments (shared within the team).
