Goldman Sachs’ chief technology officer, Atte Lahtiranta, is leaving for Citadel, Bloomberg reported Tuesday.

Lahtiranta, whom Goldman hired in 2019, will run the hedge fund’s core engineering group, and be responsible for the technology on which its trading and risk functions rely, according to the wire service.

Neither Goldman nor Citadel had issued a press release or filing on Lahtiranta’s move, and Bloomberg did not give a start date for the executive. But Citadel’s CTO — and Lahtiranta’s predecessor as Goldman’s chief tech exec — Umesh Subramanian told the wire service “we look forward to welcoming Atte.”

Lahtiranta wouldn’t be the first Goldman vet to jump to Citadel this year. Jim Esposito, the bank’s former co-head of global banking and markets, is set to join Citadel Securities as president next month.

As in recent years, 2024 has seen a rash of high-level departures from Goldman. But unlike many recent alums, who came aboard before David Solomon became CEO in 2018, Lahtiranta is a Solomon-era hire.

Lahtiranta saw his first wide-scale test as CTO when the early days of the COVID-19 pandemic forced the bank to operate remotely. More recently, tech roles at large financial institutions have put much focus on the embrace of burgeoning artificial intelligence — a prospect Citadel founder Ken Griffin says has “got the attention of the CEO.”

While at least one of Goldman’s recent departures, Stefan Bollinger, left to lead another bank (in his case, Julius Baer), several have moved to nonbank roles in finance.

Stephanie Cohen, former head of Goldman’s Platform Solutions unit, left the bank this year to become chief strategy officer at IT firm Cloudflare.

Peter Mintzberg, Goldman’s former global head of strategy for asset and wealth management, left to become CEO of crypto asset manager Grayscale last week.

Goldman’s ex-treasurer, Philip Berlinski, left the bank to become co-chief operating officer at hedge fund Millennium Management.

Others have moved into central banking. Beth Hammack, once a contender to become Goldman’s CFO, left the bank in February to succeed the retiring Loretta Mester as president of the Federal Reserve Bank of Cleveland.
