About the Role

You will translate complex legacy payments systems and customer constraints into clear, workable integrations using Polygon’s payments stack. You will independently scope integrations, lead technical discovery, build lightweight prototypes and middleware to demonstrate feasibility, and unblock deals. You will guide customers through ambiguous technical requirements, support initial implementations, and act as a technical escalation point when integrations face complexity.
