About The Role
At FINEXUS, we are building financial platforms that power digital payments and fintech services across Malaysia and the region.
We are looking for an Engineering Manager to lead the development of Cardworks and Kayaaku, our card and wallet payment platform. This role combines engineering leadership, backend architecture, and system design, ensuring our platform remains scalable, reliable, and secure as it continues to grow.
The Engineering Manager will lead a team of engineers responsible for building and operating core backend systems powering prepaid cards, digital wallets, merchant payments, and integrations with payment networks, as well as SDKs and APIs used by our partners. The role requires strong technical depth and the ability to guide engineers in designing robust financial infrastructure systems.
Why This Role Matters To Us
Cardworks and Kayaaku sit at the heart of FINEXUS digital payment ecosystem, and are strategically key for our future growth.
Kayaaku is a unique business opportunity. Finexus is currently the only e-money player in Malaysia focused on providing a platform for other businesses rather than promoting a consumer e-wallet. We believe every business should have access to a first-class cards and wallets ecosystem, with the ability to white-label their brand on it.
As adoption grows, the platform must support high transaction volumes, strong security standards, and complex integrations with financial systems. Equally important, it must provide a powerful developer experience to partners via its SDKs, and a friendly end-user experience.
This role ensures that our engineering teams design and build systems that are scalable, resilient, and capable of supporting the next generation of payment products.
