Software Developer, C++ (m/f/d)

About the role

At ARX Robotics, you will help develop the software powering next-generation autonomous ground vehicles used in governmental and civilian missions. As a Software Developer (C++), you will build high-performance systems that enable robotic platforms to operate reliably in demanding real-world environments.

You will work closely with robotics, mission, controller, and deployment teams to develop scalable software architectures, integrate hardware and software systems, and deliver mission-critical functionality from concept through deployment. Your work will directly contribute to the performance, reliability, and evolution of advanced autonomous robotic systems.

What You’ll Build

• Design and develop efficient, maintainable, and scalable C++ software for autonomous robotic platforms
• Build software components and services that enable reliable communication between hardware and software systems
• Develop and maintain integrations across CAN, Ethernet, serial, and other communication interfaces
• Collaborate with cross-functional engineering teams to define software architecture, interfaces, and system functionality
• Contribute to embedded and distributed systems that support real-time robotic operations
• Support system integration, testing, debugging, and performance optimization across the robotics software stack
• Improve software reliability, maintainability, and security for mission-critical applications
• Contribute to modern development workflows including testing, CI/CD, code reviews, and version-controlled collaboration
• Document APIs, software architecture, and technical decisions to support long-term scalability and maintainability
• Help shape the next generation of autonomous robotic systems operating in complex field environments

What You Bring

• Strong expertise in modern C++ and solid software engineering fundamentals including object-oriented design and design patterns
• Experience developing software in Linux-based environments using tools such as CMake
• Familiarity with robotics frameworks, embedded systems, or real-time software development environments
• Understanding of hardware communication protocols including CAN, Ethernet, and serial interfaces
• Experience with modern development practices including Git, CI/CD pipelines, automated testing, and collaborative code reviews
• Strong analytical thinking and problem-solving skills with the ability to work effectively across multidisciplinary teams
• Interest in robotics, autonomous systems, and high-performance software engineering
• Academic background in Computer Science, Software Engineering, Robotics, or a related technical field
• Professional proficiency in English. German language skills are beneficial but not required
• A proactive and collaborative mindset with motivation to build reliable systems that operate in the real world

Please note: You do not need to meet every single requirement to apply. We welcome motivated candidates who are eager to grow into the role and develop their expertise further.
