Job description

Senior Software Architect | Hybrid | Amsterdam

Onlyne Group is recruiting for a client, a software agency that partners with ambitious organisations to deliver complex software projects. Their people work embedded with client teams, hands-on, solving real problems rather than sitting on the sidelines.

In this role you'll work on external client projects, designing high-level architecture and setting the technical standards and patterns for development teams to follow. You'll work across different technology stacks, many of the projects run on C#/.NET and/or Python on Azure, and you'll use AI-assisted tools where they genuinely speed things up.

What we're looking for:

• 5+ years of experience in software development, with a proven track record as an architect
• Hands-on experience across multiple languages and technologies, not tied to one stack
• Solid experience with cloud platforms (AWS, Azure)
• Bachelor's or Master's degree in IT or a related field
• Strong communication skills, comfortable working directly with client stakeholders. Dutch is a plus, not a requirement
