Job Responsibilities :

The Senior Software Engineer, Payweb is responsible for designing, building, and operating full‑stack web‑based payment systems using a .NET backend and modern frontend technologies. This role focuses on correctness, reliability, and operational ownership of money‑moving workflows, including integration with external payment service providers and handling asynchronous and failure scenarios.

This position supports revenue‑critical systems and requires strong engineering judgment, end‑to‑end ownership, and accountability. The role also leverages AI‑assisted development tools to improve productivity while maintaining strict standards for financial correctness and system safety.

Key Responsibilities

• Design, implement, and maintain end‑to‑end payment flows using a .NET backend and web frontends, including checkout, top‑ups, subscriptions, refunds, and reversals

• Build and operate APIs and services using C# / .NET (e.g. ASP.NET Core)

• Develop and maintain frontend components using modern web frameworks (e.g. React or equivalent)

• Integrate and operate third‑party payment service provider (PSP) APIs

• Collaborate with backend, frontend, and platform engineers on payment state management, idempotency, and reconciliation

• Handle asynchronous workflows including webhooks, retries, and partial failures

• Ensure systems are observable through logging, metrics, and alerting

• Participate in on‑call rotations and lead investigation and resolution of payment‑related production incidents

• Review designs and implementations with a focus on failure handling, data integrity, security, and operational readiness

• Apply AI‑assisted development tools (e.g. code generation, testing, debugging, analysis) to improve productivity, while ensuring all money‑related logic is reviewed, validated, and production‑safe

• Contribute to continuous improvement of engineering standards, reliability practices, and development tooling

Minimum Qualifications

• Bachelor's degree in Computer Science, Engineering, or equivalent practical experience

• 5+ years of professional software engineering experience

• Strong experience building full‑stack web applications with .NET (C#) on the backend

• Experience developing modern web frontends (e.g. React, Angular, or similar frameworks)

• Hands‑on experience integrating payment systems or financial APIs

• Solid understanding of distributed systems concepts, including idempotency, retries, and eventual consistency

• Experience diagnosing and resolving production issues in revenue‑critical systems

• Experience using modern developer productivity tools, including AI‑assisted coding or analysis tools, in a professional environment

Preferred Qualifications

• Experience working with payment service providers (e.g. Stripe, Adyen, Braintree, or local PSPs)

• Familiarity with wallets, balances, or ledger‑adjacent systems

• Exposure to chargebacks, refunds, disputes, or fraud workflows

• Experience operating high‑availability, revenue‑generating systems

• Knowledge of compliance or regulatory requirements related to payments (e.g. PCI)

• Experience with Southeast Asia payment methods (e.g. PayNow, GrabPay)

Working Relationships

• Work closely with backend, frontend, platform engineering, product management, and customer support teams

• Interface with external payment providers during integrations and incident resolution

Additional Information

• This role is responsible for systems where accuracy and reliability are critical

• Participation in after‑hours incident response may be required

• AI tools are used to augment development, but all production changes require human review and ownership
