Job description

About Us

We’re a VC-backed stealth-mode company building behavioural AI solutions for the retail industry. Our platform is designed from the ground up — no legacy, no patchwork systems — just a clean slate and a clear vision. Our mission is to bring the intelligence of modern machine learning directly to the in-store experience, powering real-time, context-aware interactions in physical retail environments through beautifully engineered mobile experiences and developer tooling.

Role

We're looking for an experienced Mobile Engineer to lead and scale the development of consumer-facing mobile applications and client SDKs designed to transform the shopping experience from home to store. You’ll collaborate closely with our team of ML engineers, backend platform teams, and product designers to deliver high-performance, cross-platform mobile experiences that feel fast, personalized, and deeply responsive.

Responsibilities

Craft High-Grade UI/UX: Partner closely with product designers to build fluid, highly polished, and responsive user interfaces that translate complex AI-driven capabilities into intuitive user interactions.
SDK & API Design:. Design and build cross-platform mobile applications and reusable client SDKs and libraries using frameworks like Kotlin Multiplatform (KMP).
Performance & Architecture: Champion modern mobile architectural patterns (MVVM/MVI, Clean Architecture) to optimize app rendering, memory efficiency, and frame rates for a premium user experience.
Cross-Functional Ownership: Collaborate with backend and ML teams to seamlessly integrate edge intelligence models and APIs into fluid, user-facing features.

Essential Qualifications:

Cross-Platform Expertise: Proven experience building and deploying production-grade mobile applications using cross-platform technologies like Kotlin Multiplatform (KMP), Flutter, or React Native.
UI/UX Craftsmanship: A passion for mobile design, polished animations, micro-interactions, and building high-performance, native-feeling user interfaces.
SDK Development: Practical experience designing, versioning, and supporting client SDKs, mobile libraries, or developer tools.
Modern Architecture: Deep knowledge of mobile architectural patterns, modularization strategies, and writing clean, scalable, and testable codebases.
Product-Driven Mindset: Comfort working in fast-paced startup environments where you actively collaborate with product and design to make high-level technical decisions.

Nice to Haves:

Understanding of real-time protocols (eg. WebSockets, SSE) and managing complex, reactive asynchronous application states.
Familiarity with integrating client-side machine learning interfaces (e.g., executing models locally via TFLite/CoreML or lightweight ML SDKs).
Background in early-stage product development, building design systems, or creating developer-facing API documentation.
Native platform experience (Android/Kotlin or iOS/Swift) alongside cross-platform framework.
