About Hark Hark is an artificial intelligence company building advanced, personalized intelligence. One that is proactive, multimodal, and capable of interacting with the world through speech, text, vision, and persistent memory. We're pairing that intelligence with next-generation hardware to create a universal interface between humans and machines. While today's AI largely operates through chat boxes and decade-old devices, Hark is focused on what comes next: agentic systems that interact naturally with people and the real world. To get there, we're developing multimodal models and next-generation AI hardware together - designed from the ground up as a single, unified interface for a new era of intelligent systems. About the Role You'll build the iOS experience for Hark: a native app that brings a real-time, multimodal AI agent into people's pockets. That means shipping an app that feels instant, handles streaming AI responses gracefully, and integrates voice, text, and vision into a single coherent experience. The bar is high: this is the primary way millions of people will interact with Hark. This is a high-ownership role on a small team. You'll work directly with designers, platform engineers, and the people building the models. What you ship will define how Hark feels in someone's hand. Responsibilities Build and own the Hark iOS app. Architecture, UI, performance, and the end-to-end experience. Ship features that integrate real-time AI capabilities: streaming responses, voice input, tool invocations, and multimodal interactions. Work closely with designers to craft interfaces that feel fast, polished, and trustworthy. Sweat the details. Optimize for performance at every layer: startup time, animation smoothness, memory efficiency, and network latency. Own components end-to-end, from design and implementation through testing, launch, and iteration. Collaborate with platform and backend engineers on APIs, data contracts, and integration with the agent runtime.

You will: Design and implement secure scalable backend systems for Public Sector customers, leveraging Scale's modern and cloud-native AI infrastructure. Own services or systems and define their long-term health goals, while also improving the health of surrounding components. Re-architect the stack to run in compliant or restrictive environments. This requires designing swappable components (auth, storage, logging) to meet government/security mandates without breaking the product. Collaborate with cross-functional teams to define and execute the vision for backend solutions, ensuring they meet the unique needs of government agencies operating in secure environments. Participate actively in customer engagements, working closely with stakeholders to understand requirements and deliver innovative solutions.
