Lead Software Verification Engineer

We 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 a highly skilled and detail-oriented Lead Software Verification Engineer to support verification & validation tasks for the Small Engine Control Program (SEP).  The successful candidate will independently evaluate plans, requirements, implementation, test artifacts, and processes to ensure alignment with industry standards, regulatory requirements, and internal design specifications. This role will perform V&V activities in parallel with capturing the necessary information to onboard, integrate, and become familiar with client project infrastructure, standards, processes, tools, environment, architecture, and so forth.  

This role is located in Endicott, NY, and requires 100% onsite presence for 1–2 months, with the possibility of hybrid thereafter. Due to the nature of this role, US Citizenship is required.  

Key Responsibilities

• Perform software verification & validation (V&V) activities for the SEP project, including requirements-based testing and software integration.
• Support system-level HW/SW integration testing and software-level HLR/LLR verification.
• Ensure compliance with DO-178C and other relevant aerospace software standards.
• Collaborate with Systems engineers to integrate into existing infrastructure, processes, and toolchains.
• Document results, identify issues, and communicate findings clearly to both QDSS and customer leadership.
• Contribute to training and onboarding processes for future V&V team members.

Qualifications: 

• Bachelor’s degree in software engineering or a related engineering discipline  
• 6+ 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 Asymmetric Multiprocessing 
• Experience with developing software to DO-178C standards. 
• Experience with C and Python.

Preferred Qualifications: 

• 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 with complex multicore SoC, Bare-Metal Development, Cast-32A, Interference testing, worst-case execution time & Determinism, debug concepts. 
• Experience with 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/hiccups, communicate clearly, 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.
