- Prior experience building internal platforms, shared services, developer tooling, or reusable technical foundations
- Strong understanding of system design, reliability, scalability, and security considerations
- Demonstrated ability to take ownership of ambiguous technical problems and drive them from design through implementation
- Experience defining technical patterns, processes, or standards that other builders rely on
- Practical experience working with AI-powered applications, agent architectures, LLM-based workflows, or adjacent systems
- Strong communication skills and the proven ability to work cross-functionally in a fast-moving environment
- Comfort with ambiguity and a strong builder mentality, and a bias toward practical execution
