  Design, develop, execute, and update structure-aware fuzz tests against complex embedded system components using both traditional and non-traditional approaches.
• Build System Engineering:
  Read, understand, and modify complex build scripts within the CMake and Waf build systems to interpret and tune how specific software components compile.
• Containerization & Environment Management:
  Author, modify, and maintain Container files and utilize Podman commands to build secure images and manage execution environments.
• Scripting & Automation:
  Read and write robust scripts to automate software testing, verification pipelines, and deployment tasks.
• Collaboration & Communication:
  Partner cross-functionally with systems engineers and product teams to translate model characteristics and system requirements into test plans, and articulate technical findings clearly to both business and technical users.

Required Skills:

• Bachelor s Degree in Computer Engineering, Computer Science, Electrical Engineering, Systems Engineering, or an equivalent technical field.
• Ability to obtain or possess a current/or recent U.S. Government Security (DoD) Clearance. U.S. citizenship is required to obtain clearance
• Minimum of 3+ years of experience in engineering or software development working collaboratively as part of a high-functioning team.
• Deep proficiency in C and C++ programming, including expert-level management of macro definitions, raw pointers, and manual memory buffers.
• Strong understanding of Build Tools & Version Control. Tools such as Git, Git Lab workflows, and navigating/reading CMakeLists.txt files.
• Work is based in Dayton, Ohio with periodic days at WPAFB
• Travel required up to 25% for customer support and presentations

Preferred

Skills:

• Concurrent Architecture:
  Ability to design and implement multi-threaded C and C++ applications, including message-based communication and synchronization mechanisms between concurrent applications.
• Embedded & Real-Time Systems:
  General understanding of embedded systems architecture and Real-Time Operating Systems (RTOS), with an emphasis on scheduling, timing constraints, and low-level transport protocols.
• Advanced Fuzzing & Networking:
  Ability to design structure-aware fuzz tests capable of executing against in-process and remote targets.
• Networking & Communication:
  Strong proficiency in IPv4 network configuration (subnets, gateways, and routing) and experience utilizing TCP/UDP, serial interfaces, and ZeroMQ messaging patterns.
• Secure Connectivity:
  Solid understanding of SSH usage and configuration, network communications technology, and secure remote execution framework implementations.

• Ability to travel by air, car, or other transportation methods
• Prolonged periods of sitting at a desk and working on a computer (up to 8 hours/day)
• Ability to lift and carry lightweight items (e.g., laptops, demo equipment, marketing materials) up to 25 lbs.
• Frequent use of hands and fingers for typing, using a mouse, writing, and handling equipment.
• Visual acuity to read detailed technical documents, view computer screens, and operate software systems
• Auditory ability to participate in meetings, customer demos, and conference calls, including in potentially noisy environments (e.g., trade shows or military facilities)
• Mobility to move between office spaces, customer sites, conference venues, and manufacturing or lab environments
• Flexibility to adapt to varying work environments (e.g., corporate offices, government buildings, industrial or lab spaces)

• Hybrid work options
