About the Role

You’ll own the full-stack development of the Better Auth Infrastructure dashboard, the control plane our customers use to manage their auth deployments. You’ll build, ship, and evolve the product end to end, shaping architecture, defining patterns, and making tradeoffs across product experience, frontend implementation, backend systems, and data flows. You will help define what we build next and why.

Responsibilities

  • Feature development — designing and shipping end-to-end capabilities across the platform, from API contracts and data models to polished UI for users, organizations, events, security, billing, branding, and plugins
  • Product architecture — defining patterns for how the dashboard is built across frontend, backend, data fetching, permissions, analytics, and operational workflows so the system stays coherent as it grows
  • Product UX — turning complex auth and infrastructure concepts into interfaces that feel clear, trustworthy, and fast; improving navigation, hierarchy, states, and interaction quality across data-dense workflows
  • Analytics and observability — building dashboards for usage, activity, audit logs, security events, and operational insight, backed by real event and reporting pipelines
  • Performance and reliability — improving rendering, caching, query behavior, and system responsiveness across the web app and the services behind it
  • Security and enterprise readiness — implementing secure defaults, access controls, auditability, abuse prevention, and operational workflows that enterprise customers expect

Requirements

  • You can take an ambiguous product area, define the right direction, and drive it to a high-quality result
  • You think about what the user is trying to accomplish, not just what you were asked to build
  • You can create clean, functional, high-signal UI without a designer handing you every pixel
  • You’re comfortable moving across the stack, from API routes and database queries to production debugging and performance work
  • Loading states, empty states, error handling, permissions, responsiveness, and polish matter to you
  • You move quickly, make sound decisions with incomplete information, and know how to balance craft, scope, and momentum
  • Experience with design tools like Figma
  • Experience with developer tooling or infrastructure products
  • Prior work at a small startup where you owned a product surface end-to-end

About the Company

  • Better Auth is the most comprehensive authentication framework for TypeScript.
  • We're the most upvoted YC Launch in history and are used by thousands of developers shipping everything from startup projects to enterprise products.
  • We’re a small team building foundational infrastructure that other developers depend on, so the bar is high: every decision we make affects security, correctness, and developer experience at scale.
  • We’re also building an enterprise layer on top of the open-source framework for teams that need more operational, organizational, and compliance-oriented capabilities.

Equal Opportunity

  • Better Auth is an equal opportunity employer. We believe diverse teams build better security infrastructure.
