Embedded Software Engineer - Platform & Hardware Integration

Quest Defense Systems & Solutions, Inc. builds next-generation, safety- and mission-critical systems. This hybrid role in Endicott, NY offers competitive pay and an environment focused on teamwork, innovation, and balance.

You will help develop foundational embedded platforms that enable system bring-up and deterministic real-time communication with complex hardware. Work spans processor-level development, SoC initialization, and hardware/software integration for avionics and other safety-critical applications.

Responsibilities

• Develop, implement, and maintain very low-level embedded software, including processor-level C, C++, and assembly
• Lead SoC hardware initialization, board bring-up, and platform-level hardware/software integration
• Work with FPGA/ASIC components to support timing-critical and deterministic communication
• Integrate and support avionics and real-time protocols including TSN, PCIe, and AFDX
• Contribute to highly reliable embedded systems for avionics, safety-critical, or deterministic real-time environments
• Use ARM DS IDE, DSTREAM, and Python-based tooling for debugging and automation
• Collaborate with hardware, systems, and verification teams to ensure seamless integration and compliance with platform requirements
• Participate in design reviews, documentation development, and continuous improvement of embedded software processes

Requirements

• U.S. citizenship is required
• Bachelor’s degree in software engineering or a related engineering discipline
• 4+ years of relevant Software Engineering experience in avionics or electronic controls embedded development in a safety- or mission-critical environment (examples: aerospace, military)
• Proven expertise in low-level embedded development using C, C++, and assembly
• Strong background in SoC initialization, hardware, board bring-up, and system-level integration
• Hands-on experience interfacing with FPGA/ASIC logic and working with timing-critical embedded communication
• Practical knowledge of deterministic communication protocols including TSN, PCIe, and AFDX
• Experience developing software for avionics, safety-critical, or other deterministic real-time systems
• Proficiency with ARM DS IDE, DSTREAM hardware debug tools, and Python for automation and tooling

Technologies

Preferred Qualifications

• Experience developing board support packages, boot code, device drivers, or other platform-level embedded software
• Hands-on experience with new board bring-up, processor initialization, hardware debug, and early-stage system integration
• Experience supporting DO-178C, DO-254, or other safety-critical development and verification processes
• Familiarity with timing analysis, deterministic execution, latency-sensitive communication, or real-time performance optimization
• Experience using lab-based debugging equipment such as trace tools, oscilloscopes, and logic analyzers
• Experience developing Python scripts or automation tools for debugging, testing, integration, or workflow improvement
• Prior experience in aerospace, defense, avionics, automotive, industrial controls, or another regulated embedded systems environment
• Experience adopting or integrating emerging technologies (examples listed: generative AI, automation platforms, digital assistants) to improve day-to-day operations
• Active security clearance or ability to obtain a clearance
