Build and ship native iOS and Android applications using Swift and Kotlin across multiple client projects. Own work end to end from requirements and architecture through development, testing, and release. Integrate AI capabilities, maintain performance and security standards, collaborate with clients and distributed teams, and adapt across domains, technologies, and project requirements.
This is a remote position.
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
Nice to Have
- Experience delivering client projects across diverse industries
- Familiarity with Kotlin Multiplatform or shared cross-platform logic
- On-device ML experience (Core ML, TensorFlow Lite, ML Kit)
- A portfolio of shipped client apps or open-source contributions
What We Offer
- Fully remote role, based anywhere in India
- Exposure to varied, challenging projects across industries and domains
- The chance to work with cutting-edge AI tooling on real client products
