Quest Defense Systems & Solutions is seeking 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: Remote (Strong preference for hybrid/onsite in Endicott, NY) Due to the nature of this work, all applicants must be U.S. Citizens. Required Qualifications: - Bachelor's degree in software engineering or a related engineering discipline - 2+ years of relevant Software Engineering experience in avionics or electronic controls embedded development in a safety or mission-critical environment (ie: aerospace, military). - Experience developing or developing on top of an RTOS (real-time operating system), as well as familiarity with RTOS concepts. - Experience with developing software to DO-178C standards. - Experience with C, Python. - Experience with Integration and Test at both system levels (HW/SW integration) as well as software test (HLR/LLR). Preferred Qualifications: - Experience with Asymmetric Multiprocessing - Experience with debug concepts on complex multi-core SoC. - Master's degree in software engineering or a related engineering discipline. - Experience with ARM processors, associated System on Chip features, and ARM toolsets like ARM Dev Studio IDE and ARM DStream Probe. - Experience developing device drivers/board support packages. - 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. The QDSS Advantage: At QDSS, our advantage is purpose-driven work, collaborative teams, and complex challenges that push boundaries and build lasting impact. You'll grow your career while contributing to mission-critical programs that demand excellence and shape the future. What You'll Find Here - Work That Matters - Next-generation, safety- and mission-critical projects where your contributions have real-world impact. - Growth That's Supported - Competitive compensation, employer-matched 401(k), certification assistance, and clear opportunities for advancement. - A Culture That Works - A flexible, collaborative, and people-first environment where teamwork, innovation, and balance are valued. Benefits Include - Competitive pay, comprehensive medical/dental/life and disability coverage, 401(k) with employer match, professional development support, and a flexible, friendly workplace. Full compensation package is based on candidate experience and certifications Pay Ranges $100,000-$140,000 USD
