##

Our Client is a Zurich-based boutique IT and digitalization company supporting Swiss businesses in delivering tailored software solutions and technology projects. For nearly 10 years, the company has combined strong software engineering expertise with IT project management, business analysis, and strategic technology consulting. Its core expertise includes professional Excel/VBA development, process automation, digital transformation, and custom software solutions. The company focuses on pragmatic, maintainable technologies that solve real business challenges and create long-term value for its clients.

We are looking for a professional software engineer with strong Excel/VBA expertise — not simply an advanced Excel user who has created macros as part of a finance, controlling or business analysis role.

##

Your role is:

• Design, build and support business applications based on Excel, VBA and other Microsoft Office technologies

• Build solutions using modular application architecture, classes and reusable components

• Write high-quality, maintainable and properly documented code within an established development framework and shared codebase

• Implement structured error handling, debugging and systematic testing practices

• Work with data structures, databases, external data sources and integrations with other systems

• Contribute across the full software development lifecycle, from requirements analysis and implementation to code review, testing and release

• Work collaboratively using Git-based development workflows

• Participate in development sprints and contribute to continuous improvements of engineering standards and shared components

• Make effective use of AI-supported development tools while remaining fully accountable for solution architecture, security, correctness and overall code quality

• Participate in client and project meetings, discuss technical and business requirements and present completed functionality together with the Product Owner

##

Your skills and experiences:

• Several years of professional software development experience, with significant commercial experience developing solutions in Excel/VBA

• Proven experience building and maintaining complex Excel/VBA business applications, rather than only scripts, reports or isolated macros

• Very good understanding of software engineering principles, including:
• modular application architecture
• object-oriented concepts and VBA classes
• reusable components
• structured error handling
• debugging and testing
• maintainable and documented code

• Experience working with databases and external data sources from Office/VBA applications

• Experience using Git or another professional version-control workflow

• Ability to understand and contribute to an existing framework and shared codebase

• Experience working within a structured development process involving reviews, testing and releases

• Strong analytical and problem-solving skills with a high level of ownership for delivered software

• Confidence working directly with customers and discussing both requirements and delivered solutions

• Strong spoken and written English — you will actively participate in project meetings and client presentations
