Описание

Investbanq is an AI-powered wealth operating system for family offices, asset managers and banks. We are empowering traditional financial institutions to rapidly transform into AI-driven WealthTech players, enabling them to effectively capitalize on the growing wealth transfer to affluent millennials and other digital natives across emerging Asia and MENA.

Why this role matters

Our backend is the heart of the platform – processing trades, crunching analytics, and securing sensitive data in real time. You’ll own critical services built with NestJS and AWS serverless, shaping everything from data models to deployment pipelines. If you thrive on clean architecture, low‑latency code, and “everything‑as‑code” DevOps, you’ll feel right at home.

Tech stack

• Backend – NestJS / Node 20, TypeScript
• APIs – REST, GraphQL
• Data – PostgreSQL (TimescaleDB), Redis Cluster, S3
• Messaging – AWS SQS (DLQ), Redis pub/sub
• Compute – AWS ECS (Fargate), AWS Lambda
• Edge & Auth – AWS API Gateway, Cognito (OIDC)
• IaC & CI/CD – Terraform, GitLab CI, Docker
• Security – AWS KMS, envelope encryption, least‑privilege IAM
