About Hadrius

As a Founding Senior Software Engineer at Hadrius, you will own the software protecting our financial markets. From leading AI development efforts automating workflows for billions in AUM to building the pipelines streaming millions of data points, or iterating the interface used by employees at some of the biggest firms in the world. The work can change day to day and week to week, but will always involve hard technical challenges from frontend to AI to data.

You will work directly with the founding team to design and build the future of the financial system from the ground floor of a high growth startup. As we grow, there are plenty of opportunities for leadership and we pride ourselves on having a hands off culture by having very few meetings while giving engineers a broad scope of responsibility. Work alongside an elite team of engineers from Google, Chime, Microsoft, Zynga, Ivy league universities, and founders with previous exits. You'll be on a team that works incredibly hard and seeks other exceptional people excited to do the same.
