Your Role
We're hiring a lead, hands-on Solutions Engineer to support our payments and financial infrastructure products. You will operate at the intersection of product, engineering, & BD. Your role will be to translate complex, legacy payments systems and customer constraints into clear, workable integrations using Polygon’s payments stack and broader Web3 infrastructure.
This is not a pure sales role and not a pure engineering role. You are expected to independently scope integrations, unblock deals, and guide customers through ambiguity.

Requirements

• Strong background in payments, fintech, or financial infrastructure
• Hands-on familiarity with fund flows, settlement, reconciliation, disputes, and money movement
• Deep familiarity with legacy payment systems, fund flows, and real-world integration constraints
• Prior experience in Solutions Engineering, Sales Engineering, or highly technical pre-sales roles at payments companies
• Proven ability to operate independently with minimal guidance
• Strong customer empathy and the ability to explain complex systems clearly
• Comfortable coding and building small technical solutions or prototypes
• Solid understanding of APIs, webhooks, payment integrations, and system architecture

Nice To Haves

• Experience working with wallets, on-chain payments, or blockchain-based infrastructure
• Knowledge of global payment regulations (PSD2, SCA, Open Banking)
• Exposure to regulated environments and compliance-driven system design
• Experience working across time zones and with globally distributed teams

• Design and explain integrations for: Wallets Payments APIs KYC/KYB, onboarding, risk, and compliance Widgets, SDKs, hosted components, and embedded payment experiences
• Develop reference architectures, integration diagrams, payment flow documentation, and technical walkthroughs
• Serve as the technical authority in customer discussions when needed
• Demonstrate expertise in payment authorization rates, conversion optimization, and transaction success metrics
• Identify gaps between current product capabilities and customer needs
• Clearly separate what exists, what’s on the roadmap (and can be accelerated), and what requires custom or speculative development
• 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
• “Vibe code” small systems or applets to rapidly prototype and unblock integrations or demonstrate feasibility
• 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
