Design Lead - Future Openings

Join Cobalt Streamworks Help Build the Operating System for Better Long-Term Health Cobalt Streamworks is translating the principles of Medicine 3.0 into a practical, evidence-based product that helps people change the trajectory of their health. We focus on what matters most. Setting meaningful long-term goals, understanding the risks that can get in the way, and selecting the tactics that move the needle. Our approach is grounded in the ideas Peter Attia has spent his career developing. A deliberate practice with clear metrics and truly personalized plans that extend healthspan, not just lifespan. We’re building a system that takes the essential pillars of long-term health and makes them actionable. Our goal is simple. Give people a structured way to understand where they are today, what levers truly matter, and how to make durable progress over time. Why Cobalt Streamworks You will shape the foundation, not optimize at the margins We’re in the earliest stages of building something that doesn’t exist anywhere else. There are no templates. No inherited systems. The work requires people who want to solve first-principles problems and create frameworks built to last. Science and design sit at the center of everything We aim to convey complex ideas with clarity and precision. That means pairing rigorous scientific thinking with thoughtful, intuitive design; so users can understand why something matters and how to act on it. AI is part of how we work The product itself is grounded in science and behavior change. But as a team, we use AI to think, test, draft, explore, and accelerate our work. It’s a tool that enhances judgment and craftsmanship, not a replacement for either. We care about rigor, honesty, and high standards The team is small, driven, and aligned around a shared goal: build something that meaningfully improves long-term health. We challenge ideas respectfully, expect clear reasoning, and operate with a bias toward action. Precision matters. So does integrity. Join our candidate pool to be considered for future openings on our team! Note: We are not actively hiring for this role at this time. We are collecting candidate interest for future openings once we move forward with this position. About the Role We anticipate hiring a Design Lead who will own the entire Cobalt Streamworks product experience end-to-end. This is a foundational design role, very hands-on, deeply craft-driven, and essential to shaping the future of Medicine 3.0 in digital form. This is not a “brand designer” or a design manager who floats above the work. This is the person who creates the work. This role exists because: Cobalt Streamworks requires a designer who can translate extremely complex medical, behavioral, and scientific concepts into intuitive, elegant user experiences. We need a design leader who can shape visual systems, interaction patterns, and the emotional journey of the user — across iOS, web, and future surfaces. Our founders operate with high abstraction and rapid ideation; we need someone who can take abstract feedback (“this feels flat,” “this should feel more meaningful”) and turn it into precise, beautiful design decisions. As a zero-to-one product, Cobalt Streamworks needs someone who can build a design system from scratch, collaborate closely with engineering, and establish a design culture that sets the bar for years to come. You will define the visual and interaction language of Cobalt Streamworks and build the systems that allow it to scale. This is your canvas. How the Role Will Evolve Build (first 90 days) Absorb the existing Figma files, product flows, and scientific frameworks. Extend Cobalt Streamworks ’s design language including typography, color, spacing, motion, and interaction philosophy. Rebuild early designs as needed to meet a premium aesthetic and usability bar. Operate (post-launch readiness) Ship weekly product design across features, modules, and surfaces. Partner closely with Product and Engineering to scope, refine, and deliver features. Create intuitive, behaviorally-aware flows that bring Medicine 3.0 to life. Maintain high-quality handoff, documentation, and interaction fidelity. Scale & Reiterate (ongoing) Build the rituals and standards that define Cobalt Streamworks ’s design culture. Collaborate with scientific advisors to convert insights into UI and interactions. Participate in roadmap development and contribute to product strategic direction. Eventually help hire and mentor future designers as the team expands. What You’ll Do Product Design Leadership Define the end-to-end experience of the Cobalt Streamworks app. Translate complex medical and behavioral frameworks into intuitive UX flows. Lead design sprints, explorations, and high-fidelity execution. Drive clarity, simplicity, and science-backed behavior design across the product. Visual & Interaction Design Build and evolve Cobalt Streamworks ’s UX and visual identity across platforms. Own typography, layout, hierarchy, motion, color, iconography, and spatial rules. Create calm, premium, modern interfaces that feel inevitable and intent
