Role Description

As a Senior Backend Engineer you will join a product team building payment infrastructure for merchants and partner platforms.

Qualifications

• 6+ years of professional software engineering experience.
• At least 3 years of hands-on experience with payment systems or payment processing.
• Strong backend engineering experience with Go, TypeScript, and Node.js.
• Direct experience owning production payment flows rather than only performing basic payment API integrations.
• Experience integrating payment processors, gateways, or acquirers such as Stripe, Adyen, Braintree, Checkout.com, Worldpay, Fiserv, or similar providers.
• Strong understanding of the card payment lifecycle, including authorization, capture, settlement, refunds, chargebacks, and disputes.
• Understanding of bank payment rails and preferably ACH/NACHA concepts, including returns and transaction timing.
• Experience with payment reconciliation and settlement.
• Strong understanding of webhooks, retries, idempotency, asynchronous processing, and distributed-system failure scenarios.
• Experience designing relational data models for transaction-heavy systems.
• Understanding of PCI DSS and payment-security patterns such as tokenization and isolation of sensitive payment data.
• Strong attention to correctness and edge cases, especially in financial systems.
• Fluency with modern AI-assisted development tooling.
• Strong English communication skills and confidence working directly with a US-based team.
• Ability to work with 4–6 hours of daily overlap with US Central Time.

Requirements

• Experience with platform, marketplace, or facilitator models (split payments, sub-merchant onboarding, multi-party flows).
• Experience with payouts and disbursement rails, including bank-account collection, verification, and payout status handling.
• Experience with fraud and risk tooling, and bank-account validation services.
• Experience with e-commerce plugin or SDK development (WooCommerce, Shopify, Magento).
• Knowledge of multi-currency, cross-border, or alternative payment methods.
• Experience with event sourcing applied to financial state, and double-entry ledger design.

Benefits

• Reveal great tech solutions: Join the team of experts who create custom, cutting-edge tech solutions for world-renowned businesses, fueling clients' growth.
• Experience an agile and flexible working environment: Work fully remote or in a hybrid model from our office hubs, enjoy a flexible working schedule.
• Embrace the opportunity for personal and professional growth: Take advantage of performance reviews, mentorship programs, and personal development plans.
• Feel cared about: Be among like-minded people and feel supported with collaboration, open communication, and mutual respect.
