We are looking for a strong Java Payment Integration Engineer / Lead with hands-on experience building and integrating payment solutions across US and/or India payment ecosystems. Candidate must be a hands-on Java engineer with deep payment-domain expertise who can independently design, implement, troubleshoot and scale complex payment integrations-not just consume a payment API.

Responsibilities

• Own payment integration architecture and technical design.
• Lead integrations with multiple external payment providers.
• Mentor engineers and drive code and design reviews.
• Work directly with product, security, operations and external payment-provider teams.
• Lead production troubleshooting, payment incident resolution, certification and integration readiness

Requirements

• 10+ years of software engineering experience, with Java as the primary programming language.
• Strong hands-on experience with Java, Spring Boot, REST APIs, microservices, SQL, Git and automated testing.
• Proven experience integrating multiple payment gateways, processors, acquirers, wallets, or payment service providers.
• Strong understanding of the end-to-end payment lifecycle, including:
  • Authorization and capture
  • Settlement
  • Refunds and reversals
  • Recurring payments
  • Tokenization
  • Chargebacks
  • Reconciliation
• Experience with payment webhooks, asynchronous processing, retries, idempotency, timeout handling and payment failure scenarios.
• Knowledge of PCI-DSS, API security, encryption, tokenization, OAuth/API authentication and secure payment-data handling.
• US payment experience with Stripe, Adyen, Braintree, Authorize.net, Worldpay, Fiserv, Cybersource, PayPal, or similar providers is highly desirable.
• India payment experience with Razorpay, PayU, Cashfree, CCAvenue, BillDesk, UPI, or similar providers is highly desirable.
• Experience with ACH, card payments, 3DS, network tokens, card-on-file, account updater, recurring payments and payment orchestration is a strong plus.
• Experience with Kafka/messaging, AWS/Azure, Docker/Kubernetes, CI/CD and observability is preferred.
