Senior Full-Stack Software Engineer (Webfuse)

• As a Senior Full-Stack Software Engineer, you will join our Product Engineering team in Amsterdam. This is a genuinely full-stack role: projects regularly cross frontend and backend boundaries
• You will own production features from technical design and implementation through testing, release, and maintenance. Your work will include a mix of:
• Building in-session interfaces and tools using TypeScript and Vue.js
• Developing APIs and backend services using Python, Django, Django REST Framework, Node.js, and Go
• Building real-time collaboration features using WebSockets and WebRTC
• Developing browser automation, in-session extensions, and security controls
• Building integrations with customer and partner systems
• Developing MCP and WebMCP capabilities that allow AI agents to interact with Webfuse sessions
• Testing, debugging, deployment, and production maintenance are part of owning a feature - not separate responsibilities handed to another team
• As part of a small engineering team, you will have direct influence over technical decisions and how features are built
