Senior Software Engineer - Trading

Your team

At Swissblock, we are passionate about creating cutting-edge algorithmic trading strategies. Our institutional-grade trading solution delivers precision execution and deep market insights across multiple traditional financial markets.

The quant and platform engineers of our technology team create, run and maintain the automated trading platform by combining financial domain expertise, algorithmic precision, and robust engineering.

The TradFi Quant Engineering team is responsible to design, build and operate the infrastructure that powers our systematic trading business lines, as we progress towards becoming a regulated asset manager.

Your role

Our trading platform is running in production and serves two different business lines and set of strategies. The system covers data ingestion, strategy execution, order routing, portfolio management, operational workflows, post-trade processing and regulatory reporting, built on Python and Go microservices. As we grow towards full regulatory compliance, we need to extend and harden our platform across the whole trade lifecycle.

This role demands extreme ownership. You will work directly with portfolio managers, quant researchers, traders, operations, risk and compliance experts to understand business needs, translate them into technical solutions, and drive delivery from concept to production. As a Senior Software Engineer you will proactively engage stakeholders, gather and clarify requirements, identify gaps, and propose pragmatic but robust solutions before writing a single line of code.
