Quest Defense Systems and Solutions is seeking to hire Software Verification 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.

Location: Remote (Strong preference for hybrid/onsite in Endicott, NY)
Due to the nature of this work, all applicants must be U.S. Citizens.

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

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.
