Nice to Have: * GraphQL/gRPC; event-driven systems (SNS/SQS/Kafka) and background workers (Celery/RQ). * Caching, rate limiting, multi-tenancy, and feature-flag strategies. * Security & privacy best practices (PII handling, secrets management). * Deep observability experience (OpenTelemetry, SLO-based alerting). * Prior work with search/retrieval or memory systems. * On-call experience and running blameless postmortems. ## Description * 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). * Collaborate & ship: Work with frontend and research to scope APIs and deliver features to production., * 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.
