Middle/Senior Backend Software Engineer (NestJS / Node.js)

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. We are scaling quickly across Asia and MENA and are assembling a high‑calibre engineering team to power our next phase of growth.

Why this role matters

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.
