Role Summary
We have an existing Android-based POS application that needs to be migrated and rebuilt as a Windows
desktop application using WPF. You will re-architect the Android app's features, UI flows, and business logic
into a full-featured WPF application with SQLite local storage, EF Core, and existing REST API integration.
Responsibilities
Analyze the existing Android POS app and re-architect it as a WPF desktop application.
Rebuild all screens and workflows (billing, cart, product catalog, orders, reports) in WPF / XAML
following MVVM pattern.
Implement local data storage using SQLite + Entity Framework Core (Code First, migrations).
Integrate with the existing backend REST APIs (same APIs used by Android app) for product sync,
orders, payments, and authentication.
Ensure feature parity between Android and Windows versions.
Integrate Windows-specific hardware — barcode scanners, receipt printers, cash drawers.
Apply Dependency Injection, async/await, and SOLID principles throughout.
Required Skills
C# (.NET 6/8), WPF, XAML, MVVM
Entity Framework Core + SQLite
REST API consumption (HttpClient, JWT auth, JSON handling)
Ability to read and understand Android (Java/Kotlin) code and translate logic to C#
Git, Visual Studio
Good to Have
Prior Android-to-Windows or mobile-to-desktop migration experience
Payment gateway integration (Razorpay / Stripe / Paytm)
PDF / receipt generation (RDLC / FastReport)
POS, billing, or retail domain experience
AI-Assisted Development (Mandatory Mindset)
We expect the candidate to actively leverage AI tools to accelerate the migration and development process:
Use GitHub Copilot / Cursor / Claude to convert Android (Java/Kotlin) logic to C# WPF code
efficiently.
Use AI tools for boilerplate generation — ViewModels, EF Core models, API service classes, XAML
layouts.
Leverage AI for code review, refactoring suggestions, and identifying platform-specific differences
(Android vs Windows).
Use AI-assisted documentation and inline commenting to maintain code clarity during migration.
Comfortable evaluating, validating, and refining AI-generated code — not just accepting output blindly.

About Card91
Card91 is simplifying business payments by providing a plug and play issuance infrastructure to businesses for domestic and cross-border payments. Our full stack platform enables businesses to gain control and visibility into their payment flows, controlling the entire payment lifecycle from onboarding, to issuance, to transaction and data reconciliation. The platform aims to provide holistic solutions around payment issuance and distribution management. Our deep focus in payments will help us in bringing new issuance formats as well as technologies to businesses.
The company has been founded by seasoned technology entrepreneurs who have founded successful companies like Myntra, Mastiff Tech earlier. Headquartered in Bangalore, with presence in Mumbai and NCR, Card91 aims to disrupt the payment infrastructure space in the issuer-processor segment.
About the role
Our core issuance and processing system runs on Java. This system is responsible for powering the card issuance and management user experience as well. We are using Spring Boot stack for building our services.
The issuance backend team will be a small team of 2-4 developers, with a meaty responsibility to bring the user experience to life. It will be a hands-on role where every member of the team enjoys writing high quality code, and thrives on each other's experience.
If the following broad attributes sound like you, we would love to talk to you
-
4-6 years experience in backend services in Java.
-
Strong understanding of relational databases.
-
Ability to develop clean data models for complex problem domains.
-
Pragmatic approach to architecture and design - knowing when it is ok to deviate from
said best practices in the interest of practicality.
-
Above average writing and communication skills in English. Enjoy writing crisp and understandable documentation.
Why you should join
-
You enjoy working in smaller teams. We are a startup, and we believe that smaller teams are a super-power. There is lesser management overhead, and more talk about the work that matters.
-
You care about end-user and developer experience - and how the backend impacts that. Working backwards from what the user experience demands, rather than giving up to the path of least resistance.
-
We pay well (above market average). We are sufficiently capitalised by some prestigious investors in the Fintech space and we are looking at the long game. It is a fun and exhilarating journey ahead and we look forward to having some great team mates!
