About Nuclei
Nuclei is an enterprise SaaS company building the Beyond Banking and Beyond Connectivity products for banks and telecom companies across India, the Middle East, and Europe. We work with 25+ leading BFSI and telecom enterprises.

Before we started Nuclei, we listed down a few guiding principles. These were essentially the learnings from our previous startups/companies:
- Think big, think global
- Build a sustainable company, from various perspectives
- Build for the long term, take long term decisions.
- Leverage distribution
- Make our team the core product

What are we looking for?
We are looking for a Senior System Engineer to join our iOS SDK team. You will work on our core mobile SDK that is integrated into partner banking and telecom applications.

This is not a typical app development role. You will build and maintain a modular SDK that runs inside other companies' apps - handling authentication, secure token management, configuration, theming, and native-to-web communication.



Your work directly impacts how millions of users experience lifestyle services inside their banking apps.

You will be part of a small, focused integration team working closely with Android and backend engineers.

What You Will Do
- Build and maintain the iOS Core SDK that partners integrate into their apps
- Design clean, well-documented public APIs for partner developers
- Handle SDK end-to-end code with enhancements and maintenance, following best practices and secure coding
- Work with WKWebView for communication between web modules and native code
- Integrate and support the SDK across different partner banking apps — host apps can be native iOS, or cross-platform frameworks like Kony, Flutter, React Native, etc.
- Collaborate with the Android team to keep SDK behaviour and APIs consistent across platforms
- Debug integration issues and support partner developers during onboarding
- Write unit and integration tests for SDK components
- Package and distribute the SDK via
