Overview

Accountability Key Initiatives

• Design and maintain secure, PCI-compliant payment processing systems 
• Lead technical conversations with payment processor engineering teams (Stripe, payment gateways, ACH processors) 
• Establish patterns and frameworks for payment initiation, processing, and reconciliation 
• Drive initiatives to improve payment success rates, reduce failed transactions, and optimize retry logic 
• Implement comprehensive payment reconciliation systems to ensure transaction integrity 
• Provide support for payment-related escalations from tech support 
• Stay on top of current trends in payment technology and processing patterns, proposing innovative solutions to enhance our platform 

• Quality code that follows established patterns and best practices 
• Zero payment processing errors resulting in incorrect fund movements 
• Payment success rate >98% (excluding legitimate declines) 
• Payment reconciliation discrepancies resolved within 24 hours 
• Proactive use of AI development tools (Cursor, Claude, Devin, etc.) to accelerate development and improve code quality 
• Enthusiasm for leveraging AI to move fast and work efficiently 
• Consistent velocity set by manager 
• Average return rate from QA should be 2 or less 

Responsibilities

• Architect, design, and develop robust, scalable, and secure payment processing systems supporting multiple payment methods (ACH, credit card, wire transfer) 
• Partner with payment processors and gateways to understand API capabilities, fee structures, settlement timelines, and roadmaps 
• Lead the end-to-end payment processing lifecycle from initiation through settlement and reconciliation 
• Implement comprehensive payment reconciliation systems that match transactions across multiple systems (gateway, bank, internal ledger)

• Implement security best practices including PCI DSS compliance, tokenization, and secure credential management 
• Design and implement payment failure analysis and auto-retry strategies 

• Complete development tasks on time with exceptional attention to quality, performance, and regulatory compliance 
• Collaborate within a scrum team environment, translating product manager requirements into technical payment solutions 
• Create detailed runbooks for payment processing incidents (stuck payments, reconciliation gaps, processor outages) 
• Collaborate with Finance/Accounting teams to:  
• Validate payment data accuracy and resolve discrepancies 
• Support month-end reconciliation processes 
• Investigate payment exceptions and chargebacks 
• Maintain audit trails for all payment operations to support compliance requirements 
• Conduct code reviews with emphasis on payment integrity and security 
• Mentor junior and mid-level developers on payment processing best practices 
• Troubleshoot payment issues across the full stack (UI → API → processor → bank) 
• Document payment workflows, processor integrations, and reconciliation processes in Guru 
• Assist with bi-weekly production deployments (occurs after hours) 
• Participate in technical support ticket bashes for payment-related issues 
• Keep Integrations Engineering Manager updated on payment processing metrics and barriers 
• Develop comprehensive unit and integration tests for payment flows 
• Contribute to code reviews and maintain high code quality standards
