Our systems evolve through use, reflecting and amplifying the judgment of the people who work with them. We own every layer, from infra to interface, so intelligence and interaction can evolve in lockstep.\r\nWe're starting with expert software developers. But the platform we're building will adapt to experts across fields: engineering, research, operations, and beyond.\r\nAbout the Role\r\nWe're hiring a frontend systems engineer to shape the public and product-facing surfaces of Noumena's intelligence platform. This is a foundational role where UI isn't just presentation; it's how intelligence becomes legible, learnable, and trusted.\r\nYou'll build adaptive, real-time interfaces that sit directly atop our evolving models and runtime systems. You'll work across modeling, infrastructure, and product teams to ensure every surface you touch feels coherent, structured, and fast, even as it adapts in real time.\r\nThis isn't frontend-as-polish. It's frontend as interface logic, crafted for experts who think deeply and move quickly.\r\nTypeScript, React, Next.js, Tailwind, Node.js. Bonus points for experience across the stack with Python or Rust and with adaptive or model-facing UI architectures.\r\nWhat You'll Do\r\nArchitect and build production-grade UIs with real-time feedback loops\r\nLead implementation of developer-facing experiences (docs, onboarding, auth, billing)\r\nCollaborate with infra and model teams to align interaction patterns with backend logic\r\nShape internal tools that support structured planning and engineering workflows\r\nYou May Be a Good Fit If You\r\nHave deep expertise with React, TypeScript, and modern frontend architectures (e.g., Next.js, Vite)\r\nThink in systems, not stacks, designing flows and states that remain stable under complexity\r\nHave built production auth, billing, or IAM flows with performance in mind\r\nWrite maintainable, performant code that improves every system it touches\r\nKnow how to balance clarity and speed across evolving requirements\r\nLead through quality, setting standards and mentoring others by example\r\nValue developer UX, docs, onboarding, and long-term maintainability\r\nNavigate ambiguity with craft, ownership, and curiosity\r\nBonus Points For\r\nExperience building dev-facing platforms, SDKs, or public APIs\r\nFamiliarity with identity (Clerk, Auth0, NextAuth) and billing systems (Stripe, Metronome, Orb)\r\nOptimizing frontend systems for global, low-latency users\r\nExperience with SEO metadata, structured data, and indexing\r\nWhy This Role Matters\r\nThis is the surface where deep systems meet real people. It's the frontend of a frontier: the invitation to trust, to explore, to build. What you ship will shape how Noumena is seen, understood, and used.\r\nYou won't just polish a product. You'll craft the public intelligence layer of a vertically integrated system, where every pixel, prompt, and pattern is grounded in clarity, coherence, and control.\r\nTeam & Culture\r\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.\r\nWe're remote-flexible and invest in real-world time together, especially during pivotal build phases.
