A Software Engineering Role With Real Impact
Not all engineering roles are created equal. Some let you write code in a corner. Others put you at the center of something much bigger.
At Donnelley Financial LLC (DFIN), the Senior Software Development Engineer in Test (SDET) role is the latter. You won't just be catching bugs. You'll be helping protect the integrity of software that guides critical financial decisions for clients around the world.
DFIN is a leading global risk and compliance solutions company. It delivers software, data analytics, and domain expertise to clients navigating complex regulatory environments. When the stakes are this high, quality engineering matters — and that means you matter.
