Senior Software Engineer - Wallet

About the job

We are looking for a talented Senior Software Engineer to join our Product, Design, and Engineering organisation and help shape the future of spend management.

You will join our Wallet squad, part of the Payment Groups, helping build reliable, scalable, and user-friendly financial services for finance teams. This role is primarily backend-focused, with an expected split of approximately 70% backend and 30% frontend.

You will take ownership of functional and technical topics across the full feature lifecycle, from discovery and specification through technical design, development, testing, documentation, deployment, and maintenance.

As a Senior Software Engineer, you will also help shape the squad’s technical direction, lead initiatives, support strong engineering practices, and contribute to a positive and collaborative team culture.

Key responsibilities

• Design, develop, and maintain reliable services for wallet accounts, deposits, balances, cash movements, and payment flows.

• Build clear and trustworthy experiences that help finance teams understand current and future cash positions.

• Contribute to capabilities that improve liquidity, funding flows, and the movement of funds in, out, and between entities.

• Work on international and multi-entity use cases, including multi-currency wallet capabilities.

• Contribute to accounting, segregation, reporting, and operational workflows that support accurate and compliant financial services.

• Define and evolve robust architectures, applying principles such as hexagonal architecture, clear domain boundaries, and strong data consistency.

• Lead technical initiatives from discovery and design through implementation, delivery, and continuous improvement.

• Use AI-assisted development tools daily, share effective practices, and help promote responsible usage across engineering.

What we’re looking for

• Fluency in written and spoken English, our business language.

• At least 5 years of experience in software development, ideally in a product-focused environment.

• Strong expertise in TypeScript, particularly for backend development with Node.js.

• A proven track record of designing and delivering high-quality, scalable products.

• Strong architectural knowledge, including experience with micro-services and maintainable system design.

• The ability to lead initiatives and make sound decisions with a high degree of ownership and autonomy.

• A product-oriented mindset, with the ability to contribute to discovery, prioritisation, meetings, and squad rituals.

Nice to have

• Experience working in financial services, payments, fintech, or another regulated industry.

• Experience with wallet, treasury, cash management, accounting, reconciliation, or payment account products.

• Experience integrating with third-party providers through APIs, external services, and webhooks.

• Experience with ledgers, financial data consistency, event-driven systems, or event-sourcing patterns.

• Knowledge of compliance, security, banking operations, or maintaining reliable regulated platforms.

• Experience with AWS, Kubernetes, Terraform, or infrastructure-as-code.

• Experience supporting international, multi-entity, or multi-currency use cases.

As we are an international team, please submit your application and CV in English.
