Application Software Engineer

As an Application Software Engineer, you contribute to the development of applications that capture, process, and visualize human motion data.

You will work in a multidisciplinary team and report to the Manager Software Engineering. You work closely with the Software Architect and senior engineers who provide technical direction and guidance. Within this team, you are responsible for developing high-quality software and contributing to technical solutions that deliver real value to customers. You go beyond implementing requirements: you seek to understand the problem, challenge assumptions where needed, and improving solutions to robust, scalable, and maintainable solutions.

We actively leverage modern development tools, including generative AI, to accelerate development, improve code quality, and streamline engineering workflows. You are expected to be comfortable adopting these tools and exploring how they can enhance productivity and engineering outcomes.

You take ownership of your work end-to-end - from design to implementation and validation - while collaborating with your team on more complex challenges in an environment where not all requirements are fully defined., * Design, develop, and maintain application software in C++

• Translate product requirements into effective technical solutions together with the team
• Deliver high-quality, maintainable, and well-tested code
• Contribute to system behavior across UI, data processing, and application workflows
• Ensure reliability through unit testing, functional testing, and thoughtful design
• Collaborate closely with Lead Engineers, Embedded Software, Hardware, and QA teams
• Identify improvements in existing systems, performance, and developer workflows
• Take ownership of your work and deliver reliably within agreed scope and timelines

Key challenges:

• Working in a high-tech environment with evolving and partially defined requirements

• Building software that operates within a complex system of hardware, sensors, and real-time data
• Making pragmatic trade-offs between speed, quality, and scalability
• Ensuring your work contributes to meaningful user and customer outcomes

We are looking for engineers who combine strong technical skills with a proactive and solution-oriented mindset. You bring:

• Proven experience in application software development

• Strong C++ programming skills (Python is a plus)
• Solid understanding of object-oriented design and software design principles
• Experience with GUI frameworks (preferably Qt)
• Affinity with user experience and building usable applications
• Experience working on complex software systems or product environments
• A bachelor’s or master’s degree in computer science or a related field
• Strong communication skills in English (Dutch is a plus)
• Experience using generative AI tools to support software development and improve productivity is a plus

What we value in this role

• You take ownership and deliver reliable, high-quality results
• You are curious and seek to understand the user and system context
• You think in terms of solutions and outcomes, not just tasks
• You proactively contribute ideas and improvements
• You collaborate effectively and seek alignment when needed
• You are comfortable operating in an environment with ambiguity and evolving requirements
