We design systems that evolve through use, reflecting and amplifying the judgment of expert users. By owning the full stack, from silicon to interface, we ensure intelligence and interaction evolve in lockstep.\nWe’re starting with expert software developers, but the platform we’re building will adapt to experts across fields: engineering, research, planning, and beyond.\nAbout the Role\nWe’re hiring a Product Engineer to lead the design and implementation of our most critical user-facing systems: interfaces where real-time model behavior becomes structured, intuitive experience.\nThis is not frontend-as-polish. It’s frontend as product. You’ll work closely with model, infrastructure, and design leads to build tools where adaptive intelligence becomes actionable, visible, and trusted. You’ll define how these surfaces behave, not just how they look. Our users aren’t casual, they’re experts: engineers, researchers, and high-agency builders who demand clarity and precision.\nTypeScript, React, Next.js, Tailwind, Node.js. Bonus points for experience across the stack with Python or Rust, and with model-adaptive or real-time UIs.\nResponsibilities\nArchitect and build responsive, real-time product experiences\nDesign opinionated interfaces grounded in user judgment and model feedback\nShape UI logic that evolves with system capabilities\nPrototype and iterate interaction paradigms that adapt through use\nDefine workflows that support deep users, from onboarding to power use\nYou May Be a Good Fit If You:\nHave deep experience with React, TypeScript, and dynamic frontend architectures\nThink in flows and system constraints, not just layout or state\nHave built structured tools for technical users or high-leverage domains\nCare about performance, clarity, and long-term architectural health\nThrive in zero-to-one product environments and high-agency teams\nBonus Points For:\nWorking across the stack (TypeScript, Python, Rust)\nBuilding editors, structured planning tools, or real-time UIs\nDesigning for data-heavy or model-driven applications\nEngineering feedback loops between system use and behavior\nWhy This Role Matters\nThis is the surface layer of Noumena’s intelligence engine, the space where capability becomes clarity. Every interaction you shape becomes a site of adaptation, trust, and refinement. You’re not just building a product, you’re defining how usable intelligence feels.\nTeam & Culture\nWe’re a small, senior team of researchers, engineers, and builders. We value deep ownership, curiosity, and deliberate thinking. We care about coherence, from silicon to syntax, and we move with quiet urgency.\nWe’re remote-flexible and invest in real-world time together, especially during pivotal build phases. We’re radically deliberate: open to experimentation, allergic to drift, and committed to systems that matter.\nLocation & Compensation\nRemote-flexible (with travel covered for quarterly in-person gatherings)\nOpen to candidates spending time in the Bay Area during key build phases\nIncludes meaningful equity : high-impact work means high ownership\nSeniority level Seniority level Mid-Senior level\nEmployment type Employment type Full-time\nJob function Industries Technology, Information and Internet\nReferrals increase your chances of interviewing at Stealth AI Startup by 2x\nInferred from the description for this job Medical insurance\nVision insurance\n401(k)\nPaid paternity leave\nPaid maternity leave\nGet notified when a new job is posted.\nSign in to set job alerts for “Software Engineer” roles.
