iOS Developer

About Nexus

You don't have an AI story if you don't have your data story. That's where NexusOne comes in.

We're the converged data platform for the AI era — composable by design, built on an open-source foundation, and AI-native from the ground up. One identity, one governance envelope, one operational layer across every mainframe, data lake, warehouse, and streaming system in the business. For the first time, enterprises can bring their existing stack along instead of rebuilding it — and still give AI agents full context across the estate.

What we stand for is simple: sovereign data, interoperable systems, decoupled intelligence — delivered the way modern software should be. No rip-and-replace. No multi-year transformation. Our CEO Anu Jain puts it well: we turn the 'ball of yarn' of data integrations into a unified engine — less like assembling car parts, more like buying the car ready to drive.

It's working, and fast. We're tripling revenue year over year, backed by Insight Partners, and running in production in environments most vendors won't touch. Our platform processes credit risk data for 90%+ of US small businesses — 40M+ — every month.

• Design, build, and maintain native iOS apps in Swift using SwiftUI and UIKit.
• Turn Figma designs into smooth, accessible, pixel-accurate interfaces.

• Work with backend engineers to define API contracts and test endpoints with tools such as Postman or Charles Proxy.
• Write unit and UI tests with XCTest and keep the codebase clean and modular.
• Set up code signing, certificates, and provisioning profiles, and manage builds in Xcode.
• Maintain separate QA, UAT, and production builds using Xcode schemes and build configurations, following a branch-per-environment workflow.

• Strong proficiency in Swift, SwiftUI, and UIKit.
• Solid grasp of iOS architecture patterns such as MVVM, Clean Architecture, or TCA.
