Subramanian is excited for Lahtiranta's arrival, and declared: "Citadel's success has always been underpinned by both our engineering expertise and ability to attract and develop exceptional talent. We look forward to welcoming Atte as we continue to strengthen our industry-leading engineering team." Lahtiranta will have some other ex-Goldman friends at his Citadel job. Also new to the fund is Ruslan Kharitonov, a former Goldman Sachs technology fellow and global head of network and storage software engineering, who joined Citadel as head of compute engineering in July. Citadel's recent H1B hires suggest senior engineers are on salaries alone of $300k. Crowdsourced and unverified information from Levels.fyi suggests total compensation for experienced engineers can exceed $665k. Citadel CEO Ken Griffin has spoken of his admiration for people from Goldman Sachs.
