About Us

We're a custom software development company that partners with clients across industries to design and build high-quality mobile applications. Every project brings a new problem, a new domain, and a new set of users — so we're looking for a versatile native mobile developer who can adapt quickly, deliver reliably, and bring modern AI capabilities into the apps we build for our clients.

About the Role

As a Senior Mobile Developer, you'll work across multiple client engagements, building native iOS and Android applications from the ground up. You'll be hands-on through the full delivery lifecycle — translating client requirements into robust, production-ready apps — while leveraging the latest AI-intensive technologies to build smarter products and work more efficiently.

What You'll Do

Build and ship native mobile applications for a variety of clients using Swift (iOS) and Kotlin (Android)
Take features and projects end to end — from understanding client requirements through architecture, development, testing, and release
Integrate AI-driven capabilities into client apps (on-device ML, LLM-backed features, intelligent UX)
Use AI-assisted development tools to accelerate delivery timelines and improve code quality
Adapt to different project domains, tech stacks, and client expectations
Collaborate closely with project managers, designers, QA, and clients in a distributed, remote-first setup
Maintain high standards for performance, security, and code quality across every deliverable

What We're Looking For

5+ years of professional native mobile development experience, ideally in a services, agency, or consulting environment
Strong, demonstrable expertise in Swift and Kotlin
Solid command of native platform fundamentals (iOS SDK, Android SDK, lifecycle, concurrency, memory management)
Hands-on experience with recent AI-intensive technologies — working with LLMs, AI coding assistants, and/or integrating AI/ML into applications
Experience with modern architecture patterns (MVVM, Clean Architecture) and UI frameworks (SwiftUI, Jetpack Compose)
Comfort context-switching across multiple projects and client requirements
Familiarity with CI/CD, automated testing, and the full app store release process
Excellent communication skills and the ability to work directly with clients and distributed teams
