Welcome to Citadel

It shouldn’t be surprising that techies are turning to finance for innovation, fast-paced culture and connectivity with colleagues and end users. At Citadel, developers work in short life cycles on projects that create real impact. “Technology is a key component to how we out-think and out-execute those around us,” one team member said. Training opportunities in both technical and soft skills allow for continuous learning, and one of its core values, “winning,” means making the best better.

Where professional growth skyrockets

Consistent training means Citadel employees always have the opportunity to level up. And Dan would know: In his 11-year tenure, he has been promoted four times. Dan’s next move? “Mentoring and developing junior talent to give them the same opportunities I was afforded,” he said.

Fast-paced challenges lead to ample opportunities

Sam S.

Quantitative Developer

When Sam was looking for his next career move, he wanted fast-paced life cycles with more responsibility. “Citadel certainly didn’t disappoint,” he said. At Citadel, Sam develops software for a specific purpose — “out-think and outperform everyone else” — but stiff competition is saved for the competitors, not company culture. “Citadel is, without doubt, the most collaborative environment I have ever worked in.”

There is no other company out there where you can work on high-impact projects from day one and grow your career faster.
