Full Stack Engineer (C# / .NET & React) – Investment Banking

We are working with a leading global investment bank to hire a hands‑on Full Stack Engineer to help build a brand‑new, high‑impact web application from the ground up.

, taking it from concept through to production.

This role requires someone who can hit the ground running
, build the entire development pipeline
, and take ownership across the full software lifecycle—not just individual development tasks.
