What You’ll Do As part of a collaborative engineering organization, you will:

• Design, develop, integrate, and test embedded software in C/C++ for embedded processors and advanced System-on-Chip (SoC) platforms
• Lead the development of software solutions for mission-critical sensing, processing, and control systems
• Collaborate with Systems, Electrical, RF, DSP and Firmware engineers to develop integrated system solutions
• Support architecture definition, software design reviews and technical trade studies
• Perform and oversee software integration, debugging, optimization, and verification activities
• Contribute to system-level performance analysis, resource allocation, timing analysis, and reliability assessment
• Support products through development, qualification, production, deployment, and operational support
• Mentor and provide technical guidance to early-career engineers
• Participate in proposal development, technology road mapping, and new-product initiatives as opportunities arise, This role is ideal for engineers who enjoy remaining hands-on while expanding their technical leadership responsibilities. You will have opportunities to:
• Own major software subsystems from concept through deployment
• Influence system architectures and technology selections
• Lead small technical teams and development efforts
• Mentor and develop junior engineers

• Experience developing software for embedded processors, microcontrollers, or SoC-based systems
• Experience with Linux-based development environments and GNU toolchains
• Familiarity with software integration, debugging, and verification methodologies
• Hands-on experience with automated version control, CI pipelines, and bug tracking systems to support reliable software development, release and maintenance processes
• Ability to work effectively in multidisciplinary engineering teams
• Strong analytical, communication and problem-solving skills

Preferred Qualifications Experience in one or more of the following areas is highly desirable:

• Software architecture and system design
• Embedded Linux development
• ARM-based processors and SoC architectures
• Real-time operating systems (RTOS)
• Device drivers and low-level hardware interfaces
• Signal processing or sensor systems
• Model-based development and automated test frameworks
• Debugging tools such as GDB, JTAG, oscilloscopes and logic analyzers
• Aerospace, defense, space, or high-reliability systems development
• Working knowledge of CMMI or equivalent process maturity frameworks in support of disciplined software development and delivery
