Full Stack Engineer

Responsibilities

• Ship end-to-end features: Design APIs, build UIs, write backend logic, own data models, and deploy to production.
• Build for scale & speed: Optimize latency, caching, and query patterns; keep pages snappy and backends reliable.
• Own quality: Write tests, enforce typing/linting, review PRs, and maintain clean, well-documented code.
• Collaborate deeply: Work with Design for great UX, with Research to integrate new memory capabilities, and with customers to refine requirements.
• Operate what you build: Add observability, set alerts, debug prod issues, and drive continuous improvements.
• Lead with product sense: Prioritize ruthlessly, make tradeoffs explicit, and iterate based on data and feedback.
• Go beyond your lane: Unblock teams, learn new tools on the fly, and do what it takes to deliver.

Requirements

• 2+ years proven experience shipping full-stack web applications at scale. Our stack is Next.js/React and Python .
• Strong Python skills and familiarity with modern web stacks (REST/GraphQL, Postgres, Redis, Celery/queues).
• Solid front-end chops: component architecture, state management, forms, accessibility, SSR/ISR.
• Track record of owning features E2E : from design docs to rollout and post-launch iteration.
• Code quality mindset: testing (unit/integration), type safety (TS/pyright/mypy), CI/CD, and thoughtful review culture.
• Excellent communication and teamwork; comfortable working cross-functionally with design, research, and GTM.
• Comfortable operating production systems (logs, metrics, tracing) and meeting low-latency requirements.
• No CS Degree required-we care about impact and craftsmanship .
• Experience integrating LLM/memory features (RAG, embeddings, vector DBs) into products.
• Familiarity with vLLM , model serving, or lightweight ML infra integrations.
• Real-time features (WebSockets/Server Actions/streaming), file uploads, and background jobs at scale.
• Infra awareness: Docker, IaC, basic K8s/Vercel/AWS/GCP deployment patterns and cost thinking.
• Product/UI polish: Tailwind/Design Systems, charts, empty states, error UX, and performance budgets.
• Security & privacy basics (PII handling, audit/logging).
• About Mem0
• 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.
