Lead iOS Engineer

Finance is the engine of the global economy. It decides which ideas get built, which companies rise, and how resources are allocated. Yet it runs on slow tools and outdated technology.

Our mission is to transform finance. We’re building the AI analyst that makes every banker, investor, and executive smarter, faster, and more creative. When finance works better, capital flows more efficiently, innovation accelerates, and progress compounds across the entire economy. We’re not building generic AI. We are purpose-built for financial services, already working with the world’s largest banks, hedge funds, and private equity firms. Ten years from now, every financial institution will run on Rogo.

We’re looking for a Founding iOS Engineer to lead the development of Rogo’s native iOS app. You’ll play a foundational role in building out our mobile experience—from setting development standards and processes to launching user-facing features used daily by finance professionals. You’ll collaborate closely with engineering, product, and customer teams to shape the future of how users interact with AI on mobile.
You’ll own core features end-to-end: designing intuitive UX, implementing high-performance Swift code, and optimizing app performance. This is a high-impact role where your work will ship quickly, be used immediately, and drive meaningful value for our customers.
What You’ll Do

• Architect, build, and maintain Rogo’s iOS application using Swift, SwiftUI, and UIKit

• Establish and refine mobile development practices: planning, testing, releasing, and monitoring

• Collaborate cross-functionally with product, engineering, and domain experts

• Own major product features from concept to launch

• Work closely with users and Customer Success to iterate quickly and ship improvements

• Contribute to the overall architecture and direction of our mobile and frontend platforms

What You'll Need

• 5+ years of professional iOS development experience

• Strong command of Swift, SwiftUI (iOS 16+), and UIKit

• Experience building polished, high-performance apps with a focus on great UX

• Comfortable working across concurrency, threading, and performance optimizations

• Excited about crafting elegant interfaces and reusable, testable components

• Self-starter who thrives in fast-paced, high-ownership environments

• Passionate about building delightful AI-powered experiences

Bonus

• Experience integrating with backend services (REST APIs, gRPC, Server-Sent-Events)

• Familiarity with cloud platforms like AWS or Azure

• Experience deploying apps in an enterprise context (Microsoft Intune, enterprise App Store etc)

• Previous experience at a fast-growing startup

• Background at a design-forward product company (e.g. Notion, Figma)

• Strong interest in AI and how it can shape modern mobile workflows

• You thrive in fast-paced environments. You are high-intensity and care a lot about what you do, and you're ecstatic to work at a startup.

• You are ambitious. You have fun solving problems that others think are impossible.

• You are curious. You find joy in learning about AI, technology, and finance.

• You are an owner. You are autonomous, self-directed, and comfortable working with ambiguity.

• You are collaborative, organized, thoughtful, and kind.

• Exceptional traction: strong PMF with the world's largest investment banks, hedge funds, and private equity firms.

• World-class team: we take talent density seriously. We like working with incredibly smart, driven people.

• Velocity: we work fast, which means you learn a lot and constantly take on more.

• Frontier technology: we're developing cutting-edge AI systems, pushing the boundaries of reinforcement learning and published research, redefining what's possible, and inventing the future.

• Cutting Edge Product: Our platform is state-of-the-art and crazily powerful. We're creating tools that make people smarter, reinventing finance works.
