Citadel
- Citadel CTO Umesh Subramanian is stepping down after 7 years on the job.
- He will remain with the firm but work on initiatives outside technology, an internal memo said.
- Andrew Janian is returning to Citadel to serve as CTO on an interim basis.
Citadel’s top technology executive is stepping down.
Chief technology officer Umesh Subramanian is leaving the role he’s held since 2018, but he’ll stay on at the firm in a different capacity, the company said in an internal memo from COO Gerald Beeson on Wednesday.
“Umesh Subramanian will be taking on new challenges and opportunities at Citadel. After more than seven years as our Chief Technology Officer, Umesh will be working with me on important initiatives outside of technology, and we will also support his personal interest in pursuing new endeavors outside of Citadel,” Beeson said in the memo, a copy of which was seen by Business Insider.
Andrew Janian, who joined in 2021 as head of equities engineering after a long career at Two Sigma, left in early 2025 but is returning to the firm and will step into Subramanian’s role on an interim basis, effective immediately, according to the memo.
A Citadel spokesman declined to comment.
Subramanian joined in 2018 from Goldman Sachs, where he spent 13 years and rose to partner and co-CTO.
Subramanian is the second exec to vacate Citadel’s C-suite in recent months. Former CFO Andrew Philipp left in late November to join Schonfeld as co-president.
Citadel returned 10.2% in its flagship Wellington fund last year, below its peers and its recent run of industry-leading performance.
