- Apply strong PDLC experience to move initiatives from concept through validation to production readiness.
- Partner with Product and Engineering teams to clarify technical requirements, dependencies, and risks.
- Ensure architecture decisions account for real-world delivery, supportability, and platform evolution.
- Build prototypes and proofs of concept to validate architecture assumptions and demonstrate feasibility.
- Use AI-assisted coding to accelerate exploration and development.
- Explore emerging technologies, with particular attention to agentic commerce, AI agents, non-network intelligence, modern APIs, and cloud-native platforms.
- Distinguish prototype work from production-grade implementation while informing product and engineering direction.
- Create clear architecture diagrams, technical narratives, and decision materials for varied audiences.
- Present concepts and recommendations to engineers, product leaders, and senior stakeholders.
- Drive cross-functional alignment and serve as a trusted technical advisor.

- Comfortable using AI-assisted coding tools to accelerate development and validation.
- Skilled at translating complex needs into practical technical approaches.
- Strong communicator across engineering, product, business, and executive audiences.
- Able to influence technical direction across teams without direct authority.
- Experience in payments, commerce, fraud, identity, cybersecurity, or trust platforms preferred.
- Experience with agentic commerce, AI agents, or generative AI is a strong plus.
