About the Team The Future of Computing Research team is an applied research team within the Consumer Devices group focused on developing new methods, models, and evaluation frameworks that support our vision for the future of computing. We work at the frontier of multimodal AI, helping turn emerging model capabilities into product experiences that are useful, delightful, and worthy of long-term trust. Our work explores a new class of AI systems that can learn over time, adapt to individuals, and support people in the flow of daily life. This includes long-term memory, user modeling, and personalization systems that are aligned not just with immediate satisfaction, but with a person’s broader goals, values, and well-being. We work closely across research, engineering, design, product, and safety to define what it means to build AI systems that know you over time, act at the right moment, and help in ways that are context-aware, respectful, and demonstrably beneficial. About the Role We are looking for a Research Engineer / Scientist to join the Future of Computing Research team to work on RLHF and post-training for personalized, multimodal AI systems. This role will focus on building the learning and evaluation foundations that help models become more context-aware, adaptive, and useful over time.

The work is deeply product-grounded: success is not just higher benchmark performance, but better model behavior in real-world use. The ideal candidate is excited about pushing beyond one-turn assistant behavior toward systems that improve through feedback, learn from richer signals, and are trained against meaningful notions of user value. Internally, that maps closely to the need for careful reward design, feedback loops, and evaluation frameworks that test whether i

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 own Hark's hardware distribution metric. That means the strategy and the execution behind getting our device into the market at scale in its first months. You'll be the central quarterback across carriers, engineering, product, and the business teams, holding the single Concept of Operations that everyone works from and rewriting it when the data says the plan isn't working. This is a high-ownership role where the target is measurable and yours. Responsibilities Distribution Target Ownership: Carry the unit sales number end to end, and own the plan that gets Hark there on the launch timeline. Concept of Operations: Build and maintain the single central ConOps that defines how distribution runs — channels, sequencing, dependencies, and who owns what. Channel Strategy and Execution: Turn carrier and retail relationships into committed sell-in and real sell-through, from first conversation to units moving. Cross-Functional Alignment: Pull input from carriers, engineering, product, and business teams into one plan, and keep those teams working against the same commitments. Performance Review and Adaptation: Run a constant loop on data, results, and channel feedback, and change the plan the moment the numbers say it isn't working. Launch R
