team.blue hub
team.blue hub is a new internal startup within the team.blue group, created to deliver a unified, intelligent experience across all team.blue brands. Six months ago, we started building this small, top‑tier team with complete autonomy, using AI as leverage across every workflow to ship fast, think clearly, and achieve measurable results. Now, after six months in the market with the first squad,



we are growing from 1 to 3 squads to deliver a complete Hub experience.

Position
Build and maintain the core back-end systems that power the Hub: the notification engine, identification layer, data pipelines, integrations, MCP servers and clients, and the supporting AWS infrastructure. Focus on reliability, scalability, and simplicity using modern TypeScript, Python, Go, and AWS tooling.

Responsibilities
- Design and develop secure, scalable services and REST/GraphQL APIs
- Implement notification logic, identification flows, and brand integrations
- Build and maintain data pipelines (Aurora Postgres, ClickHouse, ETL flows)
- Deploy and maintain infrastructure on AWS (ECS, Lambda, S3, CloudWatch, RDS)
- Implement MCP (Model Context Protocol) servers and clients for the Hub’s agent-readiness layer
- Ensure test coverage, monitoring, and documentation
- Contribute to CI/CD pipelines and automation tooling
