- Demonstrate expertise in payment authorization rates, conversion optimization, and transaction success metrics.
- Identify gaps between current product capabilities and customer needs.
- Clarify ambiguous customer requests into clear, marketable technical scopes.
- Negotiate tradeoffs with customers to close deals when requirements don’t fully align.
- Collaborate with Sales to resolve payment integration risks early and unblock deals.
- Work with Product and Engineering to guide roadmap decisions based on customer demand.
- Influence pricing, limits, and launch phases based on technical constraints.
- Build lightweight prototypes, middleware, or example implementations where helpful.
- Read and reason about customer codebases, API specs, and architecture diagrams.
- Help customers understand how to integrate with modern systems when their internal infrastructure is outdated or rigid.
- Anticipate scale, failure modes, and operational complexity in production payments systems.
- Support initial customer implementations and early production issues.
- Act as a technical escalation point when integrations hit complexity.
- Help define what scalable post-sales support should look like over time.
