Graphics Engineer

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.

The Embedded Software team is looking for a Senior/Staff Graphics Engineer to own the graphics stack behind Hark's device display. You will share the ownership of kernel GPU driver and userspace graphics stacks, building the rendering engine and the UI framework that everything else on the product is drawn with, on resource constrained platforms with novel form factors.

This is the layer underneath the product experience. Design and our UX engineers define what the interface does; you define the capabilities of  the interface.

• →Own Display & Graphics stack: Design, develop, and maintain the display pipeline across different embedded platforms
• →Work directly with Design and with the UX engineers to get real designs onto the device at full fidelity.
• →Performance Optimization: Analyze and optimize the graphics pipeline to ensure high performance, low latency, and efficient memory bandwidth across different graphics pipelines and architectures
• →Establish the practices for graphics development, testing, performance regression, and CI.

• 7+ years of industry experience in graphics or UI engineering.
• Deep hands-on experience with Vulkan and OpenGL ES, including shader authoring (GLSL/SPIR-V) and render pipeline design.
• Strong experience with vector graphics rendering and animation.
• Proven track record on embedded or resource-constrained systems: limited RAM, limited GPU, real thermal envelope.
• Solid C++ and familiarity with Linux userspace development.
• Experience owning a UI framework or rendering engine that other engineers built on top of.
• Strong cross-functional communication. 

• Familiarity with low level display HW including Serializer/Deserializer, video links and display interfaces
• Familiarity with display virtualization
• Experience with both retained-mode and immediate-mode  rendering frameworks..
• SVG or other vector formats and their GPU-accelerated rendering.
• Understanding of display hardware interfaces (MIPI DSI, HDMI) and display driver integration on embedded Linux.
• Game engine experience (Unreal, Unity).
• Shipped a custom system-level UI framework or graphics stack on a commercial device.
