Position Summary:

Our partner is a technology company focused on transforming traditional vehicles into autonomous systems used in defense and industrial environments. They are seeking a C++ Software Engineer to join their team. This opportunity sits between systems engineering and user-facing software, with a focus on building and maintaining Linux-based applications that process real‑time data and present it through Qt and QML interfaces. The goal of this engineer is to improve the reliability, performance, and clarity of a live C++ application by evolving real‑time systems and user‑facing interfaces without disrupting production operations.

Experience and Education:

• BS in Computer Science, Information Technology or equivalent experience/field
• Experience building and maintaining production C++ applications used in operational, mission‑critical, or customer‑facing environments
• Hands‑on work in Linux‑based systems, including debugging, performance analysis, and working with real‑time data flows
• Experience developing operator‑facing or desktop applications where performance, clarity, and reliability matter
• Experience integrating UI layers with backend or systems components
• Practical use of modern C++ (C++11 and newer) in multi‑threaded, concurrent systems
• Experience working in existing, complex codebases, improving features without disrupting live systems
• Familiarity with domains such as autonomous systems, robotics, automotive, aerospace, or defense software

Skills and Strengths:

• C++
• Qt
• QML
• Multithreading
• Concurrency
• RAII
• Qt Widgets
• gdb
• POSIX APIs
• CMake
• Publish‑subscribe architectures
• DDS
• ROS
• Performance profiling

Primary Job Responsibilities:

• Design, build, and maintain production‑grade C++ applications running in Linux environments
• Develop and enhance Qt and QML‑based user interfaces that present real‑time system state, telemetry, and operational data
• Integrate application‑layer software with distributed systems, autonomy platforms, and real‑time messaging layers
• Debug and resolve issues in live Linux systems, including performance, concurrency, and stability problems
• Implement and optimize multi‑threaded components to support reliable real‑time data handling
• Improve system clarity and responsiveness, ensuring users can trust what the software is showing them
• Work within large, existing codebases, delivering new features without disrupting deployed systems
• Collaborate closely with cross‑functional engineering teams, including systems, autonomy, and operations
• Apply proven design patterns with an emphasis on reliability, maintainability, and operational safety
• Evaluate failure modes, edge cases, and performance risks before changes are released
• Participate in code reviews focused on production readiness and long‑term support
• Document system behavior and technical decisions to support ongoing operational use
• Support evolving requirements as platforms, integrations, and customer needs change
• Communicate technical tradeoffs clearly with both engineers and non‑technical partners
