Embedded Software Engineer - Multicore Platforms & Avionics Networking

Summary

Quest Defense Systems & Solutions is an aerospace and defense engineering company focused on safety- and mission-critical systems. The Embedded Software Engineer will develop low-level software for multicore processors and SoC platforms, deterministic avionics networking, and DO-178-compliant environments. The role also involves hardware/software integration, debugging, testing, and collaboration across engineering teams.

Responsibilities

• 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

• * 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
• 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
• * 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
