• Talk to customers regularly to surface workflows, pain points, and unarticulated needs
• Collaborate with product, design, and commercial teams to shape the roadmap and translate customer insight into technical solutions
• Prototype and ship quickly using AI coding assistants (e.g., Claude Code) to accelerate development
• Build scalable APIs and backend services for document processing and data extraction
• Design reliable streaming and event-driven architectures for real-time experiences
• Develop polished frontend experiences that make AI capabilities accessible
• Implement integrations with enterprise systems and third-party platforms
• Implement privacy and security by design
• Champion engineering best practices: testing, observability, CI/CD, and infrastructure-as-code
• Mentor engineers and help instill product-thinking across the team
