# Embedded Software Engineer - Multicore Platforms & Avionics NetworkingUnited States4 hours agoID 5839816Price on request## DetailsEmployment type: Full-timeRemote: YesCompany: Quest Defense Systems & Solutions, Inc.Level: Any## DescriptionWe don’t just build technology—we engineer the future. From next-gen aerospace to cutting-edge defense systems, we tackle the toughest, mission-critical challenges that keep people safe and push the limits of innovation. This is where problem-solvers, innovators, and big thinkers thrive. Quest Defense Systems & Solutions is seeking an Embedded Software Engineer with experience developing low-level software for multicore processors and System-on-Chip platforms. This role requires hands-on experience with deterministic avionics networking—particularly Time-Sensitive Networking, ARINC 664 Part 7/AFDX, or related ARINC communication standards—as well as development within a DO-178 environment. You will work at the intersection of software and hardware, developing processor-level software, enabling new hardware platforms, and integrating multicore systems with FPGA, ASIC, and other custom hardware. Location: Remote candidates will be considered provided they are available for an initial onboarding period in Endicott, NY and can travel to the site on a quarterly basis thereafter. Citizenship: U.S. citizenship is required W hat You’ll Do • Design, develop, and maintain low-level embedded software using C, C++, and Assembly. • Develop software for multicore processors and SoCs, including processor initialization, inter-core communication, synchronization, shared-resource management, and deterministic execution. • Develop and integrate deterministic avionics networking solutions using TSN, ARINC 664 Part 7/AFDX, PCIe, and related real-time communication technologies. • Develop board support packages, boot code, device drivers, and other platform-level software. • Support new hardware bring-up, board initialization, and hardware/software integration. • Integrate embedded software with FPGA, ASIC, and custom hardware components. • Develop software in accordance with DO-178B/C processes and applicable safety-critical requirements. • Analyze and troubleshoot timing, latency, concurrency, and real-time performance issues. • Debug processor- and board-level software using hardware debuggers, trace tools, oscilloscopes, logic analyzers, and related laboratory equipment. • Develop Python-based tools to support debugging, testing, automation, and integration. • Collaborate with software, hardware, FPGA, ASIC, systems, and verification engineers throughout the development lifecycle. • Participate in software architecture, design reviews, testing, technical documentation, and continuous process improvement. Required Qualifications • Bachelor’s degree in Computer Engineering, Software Engineering, Electrical Engineering, Computer Science, or another relevant STEM discipline. • 4+ years of embedded software or firmware development experience in aerospace, avionics, defense, or another safety- or mission-critical environment. • Strong programming experience with embedded C and C++. • Experience developing very low-level, real-time embedded software, such as BSPs, boot code, device drivers, processor initialization, or platform software. • Hands-on experience developing software for multicore processors or multicore SoCs. • Experience with deterministic avionics networking or communications, including at least one of the following: • Time-Sensitive Networking • ARINC 664 Part 7 or AFDX • Related ARINC avionics communication standards • Experience working within a DO-178B/C software development lifecycle. • Experience with board bring-up, hardware initialization, or hardware/software integration. • Experience interfacing embedded software with FPGA, ASIC, or other custom hardware. • Experience debugging embedded systems using hardware debugging or trace tools. • U.S. citizenship. Preferred Qualifications • Experience with ARM processor architecture and ARM-based SoCs. • Experience with PCIe or other high-speed hardware interfaces. • Experience with RTOS, bare-metal, or embedded Linux development. • Experience analyzing timing, latency, concurrency, WCET, or deterministic system performance. • Experience with ARM Development Studio, DSTREAM, or comparable processor-debugging tools. • Experience using oscilloscopes, logic analyzers, and other laboratory equipment. • Experience developing Python scripts for debugging, testing, or workflow automation. • Familiarity with DO-254 and hardware/software design assurance activities. • Active security clearance or the ability to obtain one.
