Polygon Labs is a software development company building and developing a network of aggregated blockchains via the Agglayer, secured by Ethereum. As public infrastructure, the Agglayer will bring together user bases and liquidity for any connected chain, and leverage Ethereum as a settlement layer. Polygon Labs has also contributed to the core development of several widely-adopted scaling protocols and tools for launching blockchains, including Agglayer CDK, Polygon PoS & Katana.
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.
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
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
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
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
