Senior Software V&V Engineer - DO-178 / Multicore SoC

Engineers are the reason we exist—they’re the core of who we are. Embark on a journey with EXB Solutions at the forefront of technological innovation as we seek talented Engineers to shape the future of cutting-edge projects and contribute to a culture of excellence and creativity.  What we do matters.   

Quest Defense Systems & Solutions is seeking Senior Software V&V Engineers with experience in safety-critical embedded systems to support advanced aerospace and defense programs.

You’ll be verifying and validating software running on RTOS-based, multicore SoC architectures, ensuring compliance with DO-178C and alignment to system-level requirements. This includes hands-on work across integration, system test, and software verification (HLR/LLR) in complex hardware/software environments.

This role is ideal for engineers who understand the added complexity multicore introduces in certification, including timing, determinism, and partitioning concerns.

Location: Endicott, NY (potential to be hybrid)
Due to the nature of this work, all applicants must be U.S. Citizens.

• Familiar with data transfer protocols (ARINC 615A, ARINC 429, MIL-STD-1553, PCIe, LIN, CAN). 
• Familiar with security concepts (authentication, authorization, confidentiality). 
• Familiarity with actuators and sensors like stepper/torque motors, solenoids, relays, VDT, VRT, etc. 
• Experience BVA (boundary value analysis), SCA (structural coverage analysis), DCCA (data and control coupling analysis). 
• Experience with DO-330 Tool Qualification. 
• Good soft skills: communication, ability to perform active listening, self-manage, raise/elevate roadblocks and hiccups, communicate clearly, and take direction. 
• Good general understanding of engineering principles to be able to adapt to new projects/environments and come up to speed quickly. 
• Team leadership experience, including project technical leadership and/or software functional leadership. 
• Experience in the adoption and/or integration of emerging technologies (e.g., generative AI, automation platforms, digital assistants) into day-to-day operations for continuous improvement.
