Position Description:

As a Senior Software Engineer, you will play an instrumental role in realizing and supporting several customer-facing Payments journeys using AI-first development workflows combined with modern software engineering practices.

As our Senior Software Engineer, you will get under the hood of a Cloud / Serverless-based tech stack (Digital Product Layer) to realize secure, scalable and reliable backend software that facilitates seamless data journeys originating from mobile applications and/or core banking systems, whether onboarding new customers, initiating and receiving payments, provisioning digital wallets, or checking transactions.

For realizing and supporting such mission-critical data journeys on AWS Cloud, you will adopt modern software engineering practices including AI-first development workflows, DevOps, shift-left practices and test automation.

You will work primarily with TypeScript, GraphQL (backend), and React Native in a distributed microservices environment with extensive exposure to AWS Serverless technologies (API Gateway, Lambda, DynamoDB,



SQS, SNS, Step Functions, Secrets Manager, KMS and more), alongside Azure DevOps for building and releasing software components.

This is not just a backend role. The features you build touch cryptographic boundaries: you will work with JWE/JWT-based integrations, PCI-scoped Lambda environments, certificate lifecycle management, and mTLS, applying security thinking from the ground up rather than as an afterthought. You will be expected to carry a DevSecOps mindset into your daily work, treating security as a first-class engineering concern across design, implementation, and operations.

Responsibilities

• Responsible for the technical delivery and support (build and maintain) of selected customer journeys in the Payments space, involving integrations with third-party card schemes, wallet providers, and core banking systems.
• Actively participate in technical refinement, bringing clarity
