Senior Java Full-Stack Developer

Project Description:

Join a Team Redefining Modern Banking Technology!

Our client is a Swiss bank focused on delivering advanced online trading and financial services. Unlike traditional financial institutions heavily dependent on legacy systems, this bank invests in a lean, modern, and continuously evolving technology stack.

What the Project Is About
The project focuses on building and evolving a large‑scale trading platform used by a wide range of clients - from private investors to active traders.
The platform enables:
* Trading across multiple financial instruments: Shares, ETFs, Options, Futures, Funds, Bonds, CFDs
* Support for complex order types: Market, Limit, FoK, OCO, Trailing, and more
* Order Routing Systems (ORS) that intelligently route trades to the correct broker and marketplace
* FIX‑based integrations with multiple brokers and exchanges
* Direct connectivity and maintenance for key markets: SIX, Eurex, Bern, Scoach
* Tools for internal Derivatives teams to manually manage and recover orders when needed
* Accurate commission calculation and management per order

The platform is business‑critical and operates under strict performance, reliability, and correctness requirements, serving as the backbone of the client's trading ecosystem.

Technology & Engineering Culture
We continuously evolve our systems toward:
* Atomic, independently deployable microservices
* Self‑contained applications with clear ownership
* Dockerized environments
* Automated CI/CD pipelines
Engineering decisions focus on reliability, transparency, and scalability, supporting business‑critical banking systems.

How We Work
Scrum teams of 7-8 cross‑functional engineers. Each team member contributes to both backend and frontend components.

Daily collaboration with client stakeholders through:
* Stand‑ups
* Refinement and design sessions
* Status and planning meetings
Agile best practices applied across delivery

Primary communication tools:
* Microsoft Teams
* Outlook and internal collaboration platforms
