Temporary Software Engineer Jobs in Orange, CA (NOW HIRING)

Job Title: Senior Software Engineer (Embedded Firmware & Connected Vehicles)
Role Overview
We are seeking an experienced, visionary, and hands-on Senior Software Engineer to play a pivotal role in the design, development, testing, and release of advanced software-defined vehicle platforms and embedded firmware solutions. In this role, you will partner with skilled developers and cross-functional engineering teams to drive our digital and vehicle engineering roadmap from concept to production.
This is a senior technical leadership role combining low-level embedded firmware development with connected vehicle telematics and cloud architecture. You will design real-time controls for ECUs and TCUs, implement secure vehicle-to-cloud data pipelines, ensure compliance with functional safety standards (ISO 26262), and mentor junior engineering talent. If you are passionate about building cutting-edge mobility technologies and leading by example, we want to hear from you.
Key Responsibilities
Embedded Firmware & Real-Time Controls
• Firmware Development: Design, code, test, and maintain real-time embedded firmware for automotive Electronic Control Units (ECUs), Telematics Control Units (TCUs), and microcontrollers.
• Low-Level Architecture: Implement device drivers, Hardware Abstraction Layers (HAL), bootloaders, and Board Support Packages (BSPs) across bare-metal, RTOS, FreeRTOS, and Linux environments.
• Bus Integration: Integrate complex automotive communication protocols including CAN, CAN-FD, LIN, Ethernet (100BASE-T1), and FlexRay.
• Functional Safety: Ensure software strictly complies with functional safety standards (ISO 26262 / ASIL) and coding guidelines (MISRA C/C++, AUTOSAR).
Connected Vehicle Platforms & Telematics
• V2X Pipelines: Architect and implement TCU software to handle secure vehicle-to-cloud (V2X/V2C) data pipelines utilizing LTE/5G, GPS/GNSS, Bluetooth, and Wi-Fi.
• IoT Messaging: Develop secure, lightweight IoT messaging protocols (e.g., MQTT, gRPC, Protobuf, HTTP/REST) for real-time vehicle telemetry and edge diagnostics.
• OTA & Edge Analytics: Architect reliable Over-The-Air (OTA) update systems with rollback capabilities and build edge data caching mechanisms to optimize cellular bandwidth.
Testing, Security & Leadership
• Cybersecurity: Implement robust security safeguards including Hardware Security Modules (HSM), Secure Boot, end-to-end encryption (TLS), and key management.
• Validation & Debugging: Utilize Hardware-in-the-Loop (HIL) test beds, oscilloscopes, logic analyzers, and Vector tools (CANoe, CANalyzer) to debug low-level hardware/software interactions.
• Technical Mentorship: Lead from the front in Agile scrum ceremonies, mentor junior and offshore engineers, and foster a culture of innovation and engineering excellence.
Qualifications & Requirements
Minimum Qualifications
• Education: Bachelor's degree in Computer Science, Software Engineering, or a related technical discipline (or equivalent professional experience).
• Experience Baseline: Minimum of 8+ years of relevant experience in firmware and software development within automotive, mobility, logistics, or related hardware-software industries.
• Technical Mastery:
o5+ years of deep expertise in Embedded Firmware & Real-Time Controls (ECUs, TCUs, HAL, BSPs, RTOS, and CAN/Ethernet protocols).
o5+ years of hands-on experience in Connected Vehicle Platforms & Telematics (V2X pipelines, MQTT, OTA update systems, and edge telemetry).
o2+ years of specialized experience in automotive cybersecurity (HSM, Secure Boot) and hardware testing/debugging utilizing HIL test beds and Vector tools (CANoe).
oProven adherence to functional safety standards (ISO 26262 / ASIL) and coding standards (MISRA C/C++, AUTOSAR).
• Core Competencies: Strong communication skills to align cross-functional teams on complex architectural decisions; ability to "lead by doing" across coding, design, and execution; passion for mentoring and maximizing team potential.
