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.

Your Responsibilities

Pre-Sales Solutions Engineering

• Support BD in late-stage deals and technical evaluations

• Lead technical discovery with customers, focusing on complex legacy payments, fund flows, and compliance

• Align customer business models (tradfi, fintech, platforms, embedded finance, global payments) with scalable payment architectures

• Translate customer business and system requirements into implementation plans

• 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
  

Integration & Deal Shaping

• 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
  

Technical Execution

• 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
  

Post-Sales

• 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

What You'll Need

• 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

• Distributed systems experience helpful but not required

Preferred Qualifications

• 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
