Mem0 is looking to hire a backend engineer to own and develop the backend systems that power their memory platform for AI agents, enabling AI to remember conversations, learn from interactions, and build context over time.
Requirements
- 3+ years building backend systems and shipping REST APIs to production.
- Strong Python fundamentals; experience with async programming and a major web framework (FastAPI/Django/Flask).
- Solid data modeling and SQL skills; hands-on with query tuning and performance debugging in Postgres/MySQL.
- Experience with graph databases (e.g., Neo4j or Amazon Neptune) and appropriate data modeling trade-offs.
- Comfortable running services on AWS with Docker and Kubernetes.
- Demonstrated root-cause analysis and ownership from incident to prevention.
- GraphQL/gRPC; event-driven systems (SNS/SQS/Kafka) and background workers (Celery/RQ).
Responsibilities
- 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/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/Starlette, 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 metrics, structured logging, tracing; set SLOs and alerts (CloudWatch/Prometheus/OpenTelemetry).
Other
- Collaborate tightly with frontend and research to deliver fast, reliable features.
- Clear communicator and effective collaborator with frontend, research, and customers.
- Office-first collaboration - We're an in-person team in San Francisco.
- Extreme ownership - Everyone at Mem0 is a builder-owner.
- High bar, high trust
