About Mem0
We're building the memory layer for AI agents: long-term memory that lets AI remember conversations, learn from interactions, and build real context over time, the difference between a chatbot and something that actually knows you. We're already powering millions of AI interactions for enterprise customers and a rapid-growing open-source community (160k+ developers and counting).
We're backed by top-tier investors through a $24M Series A & Seed, early enough that the systems you build now become the foundation everything else is built on.
This role owns the backend behind that platform. You'll design clean REST APIs, model data across relational and graph stores, and operate services in production. When customers hit issues, you'll chase them down to root cause, ship fixes, and harden the system, working closely with frontend and research to deliver fast, reliable features.
You'll design the core systems, decide how they're built, and stay with them through production. Our users are developers integrating us into their own agents,



which means the APIs you design are the product as far as they're concerned.
This role reports directly to Deshraj Yadav, our Co-founder and CTO, and works closely with the engineering team in San Francisco.
What you'll do
Design & ship REST APIs: Define contracts, versioning, auth, rate limits; write migrations and docs.
Model data & schemas: Relational (Postgres) and graph (e.g. Neo4j); enforce integrity and performance.
Debug customer issues end to end: Trace with logs, metrics and traces, reproduce, fix, and write preventative guardrails.
Optimize performance: Tune slow SQL with EXPLAIN/ANALYZE, indexes, partitioning, pagination, and caching (e.g. Redis).
Build services in Python: Async where it helps (FastAPI, Django/DRF, Flask), background jobs, queues, schedulers.
Operate in the cloud: Containerize with Docker, deploy on Kubernetes (EKS), and use AWS primitives (EC2, RDS/Aurora, S3, IAM).
Instrument everything: Custom metr
