Back End Engineer Needed

About Project: Multi-tenant exhibition platform that powers AI-guided, gamified visitor experiences for live venues.

✅ Experience: • Strong production experience on AWS (Lambda, ECS, Aurora or RDS, and the surrounding services) • Deep PostgreSQL: schema design, query performance, and hands-on experience with row-level security or another rigorous approach to multi-tenant data isolation • TypeScript fluency on the server side • Experience designing event-driven or streaming systems (SQS, Kinesis, WebSocket, or equivalent) • A track record of operating production services: metrics, tracing, alerting, on-call response

✅ Nice to Have: • LLM integration in production: prompt engineering, streaming inference, latency and cost optimization • Real-time audio or TTS pipelines • B2B multi-tenant authentication (Stytch, Auth0, Cognito, or similar) • Reading Rust (one Rust service in production) • Headless CMS integrations • Beacon, BLE, or other sensor-data ingestion pipelines • Background in cultural, museum, live-event, or exhibition technology

✅ Tech: AWS end-to-end. Lambda and ECS Fargate for compute, Aurora PostgreSQL with pgvector and row-level security for data, ElastiCache Redis, S3 + CloudFront, SQS for fan-out, API Gateway in front. TypeScript on the services, Rust on the streaming layer. Stytch for authentication. PostHog and Mixpanel for analytics. Terraform per service, GitHub Actions for CI/CD.

✅ English level: Upper intermediate (Must be able to speak fluently!)

❌ We don't work with RF or RB!
