Build end-to-end features in Next.js/React: dashboards, complex forms, data visualizations, and reusable UI components.
Manage state confidently (Redux, Zustand) and design predictable data flows.
Own quality: write extensive tests (Jest/Vitest, Testing Library, Playwright/Cypress), type safety with TypeScript, and clean docs.
Create/share libraries: publish and maintain internal/external npm packages and component libraries.
Ship for performance: SSR/ISR, code-splitting, caching, accessibility (WCAG), and Lighthouse/Web Vitals budgets.
Integrate with backends: define API contracts, consume REST/GraphQL, and collaborate with backend engineers to deliver features.
Operate what you build: Deploy on Vercel, set up CI/CD, logging, basic analytics/feature flags, and monitor UX regressions.
Iterate with users: partner with Design and customers, run quick loops, and refine UX based on real usage.
Minimum Qualifications
Production experience with Next.js or React building modern SPAs/SSR apps.
Strong JavaScript/TypeScript fundamentals and state management expertise.
Proven track record shipping e2e features across the JS stack (frontend + API integration).
Experience writing robust tests across unit, integration, and E2E layers.
Experience deploying and operating apps on Vercel (or similar platforms).
Clear, proactive communication; comfortable collaborating with Design, Backend, and customers.
Attention to code quality: thoughtful architecture, linting/formatting, PR reviews, and maintainable components.
Nice to Have:
Built and published npm packages, Storybook-driven component systems, or design tokens.
Data viz and real-time UX (charts, streaming, websockets, server actions).
Performance tuning at scale (RUM, Core Web Vitals, bundle analysis).
Monorepos (Turborepo), module federation, or micro-frontends.
Basic backend fluency (Node/Edge functions) to unblock yourself when needed.
About Mem0
We're building the memory layer for AI agents. Think long-term memory that enables AI to remember conversations, learn from interactions, and build context over time. We're already powering millions of AI interactions. We are backed by top-tier investors and are well capitalized.
Our Culture
Office-first collaboration - We're an in-person team in San Francisco. Hallway chats, impromptu whiteboard sessions, and shared meals spark ideas that remote calls can't.
Velocity with craftsmanship - We build for the long term, not just shipping features. We move fast but never sacrifice reliability or thoughtful design - every system needs to be fast, reliable, and elegant.
Extreme ownership - Everyone at Mem0 is a builder-owner. If you spot a problem or opportunity, you have the agency to fix it. Titles are light; impact is heavy.
High bar, high trust - We hire for talent and potential, then give people room to run. Code is reviewed, ideas are challenged, and wins are celebrated—always with respect and curiosity.
Data-driven, not ego-driven – The best solution wins, whether it comes from a founder or an engineer who joined yesterday. We let results and metrics guide our decisions.
