Job description

Lead Mobile Engineer London, United Kingdom (Remote) 120k - 180k Base + Significant Equity

Our client is building the operating system for finance.

While businesses rely on modern tools for almost everything, finance teams are still largely dependent on outdated software built decades ago. This AI-native ERP platform is changing that by automating accounting workflows from data entry through month-end close, helping businesses move faster, reduce costs, and operate with greater confidence.

In just two years, the company has raised over $100M from leading investors and is already trusted by customers ranging from high-growth startups to publicly listed enterprises.

Why This Opportunity?

This isn't another mobile engineering role where you're maintaining someone else's codebase.

You will be the company's first dedicated mobile hire, responsible for building and owning the mobile experience from the ground up. You'll have the opportunity to shape architecture, influence product direction, and define how mobile fits into the future of the platform.

You'll join a high-performance engineering culture built around speed, ownership, and execution.

What You’ll Be Doing

• Build and ship production-grade iOS and Android applications using React Native and TypeScript
• Own mobile architecture decisions from concept through deployment
• Manage the entire release process across the App Store and Google Play Store
• Build and maintain Expo and EAS deployment pipelines
• Collaborate closely with product and design teams to turn Figma designs into exceptional user experiences
• Integrate seamlessly with backend services and APIs
• Optimize application performance, reliability, and scalability
• Drive best practices across testing, monitoring, and mobile development standards

What We're Looking For

• 5+ years of Android development experience
• Proven experience owning products and features end-to-end
• Experience taking products from ideation through production release
• Experience with Expo and Expo Application Services (EAS)
• Deep understanding of App Store and Google Play release processes
• Experience integrating with backend systems and APIs
• Strong focus on performance optimization and app quality

You’ll Thrive If You Are

• Highly autonomous and proactive
• Comfortable making decisions without constant direction
• Someone who takes complete ownership of outcomes
• A strong communicator with excellent English skills
• Passionate about building products rather than simply writing code
• Able to solve engineering problems without relying solely on AI tools
