Morning Coffee: How AI is changing demand for developers at Citadel Securities. Bad news about the deal rebound

If you're an engineer looking for a software development job in finance, Citadel Securities is one of the more aspirational and highest paying places (alongside Jane Street) you could work for. But, being a brilliant software developer is no longer enough. As large language models and AI permeate financial services, the kinds of people Citadel Securities needs to work on its electronic trading platform is changing. 

"The days of 'I'm a good programmer' are becoming numbered," Ken Griffin, Citadel Securities' founder, told the interns there this summer, according to Business Insider. Now that large language models can create code, it's less about translating problems into code than about solving problems themselves. Those problems can be ambiguous, and they often have commercial constraints.

Costas Bekas, a technologist who heads up Citadel Securities' research platform, told Business Insider that cloud platforms, for example, can be cumulatively expensive and that people need to be aware of this and to "become owners of what they do."

As developers increasingly rely upon AI to do coding work, Damien Neff, Citadel Securities's head of systematic trading technology, said it's simultaneously becoming more difficult to find people who can still do the really low level coding that's needed to interact with hardware and to process trades in the fastest possible way.  AI means that technologists see things at a "high level" said Neff, and they're losing this really low level coding ability. 

If you want to get a technology job at Citadel Securities in the age of AI, therefore, you either need to be excellent at solving problems in a commercial way, and communicating about that, or you need to be deep in the machine code weeds. The latter is probably harder to replicate. A previous generation of machine code veterans are nearing retirement - in 2019, Citadel hired Stuart Feldman, a veteran scientist from Bell Labs and creator of the first Fortran compiler, to advise its CEO on CTO on coding on the metal. Feldman is still there and by our reckoning he's approaching his 60s now. 

Separately, if you were hoping that the recent spate of IPOs signalled a recovery in deals and an improvement in the investment banking jobs outlook, then bad luck. Bloomberg reports that war in the Middle East, surging treasury yields, and a series of underwhelming IPOs are all putting the brakes on the new issuance rebound. There's some expectation that the IPO window might reopen from March '24. In the meantime, the most excited people are in convertible debt, which should thrive in a world where rates are higher for longer.

Under basis trades, a hedge fund will sell Treasury futures and simultaneously buy the corresponding bonds. By buying cheaper bonds in one market and selling expensive ones in the other, traders can profit from the small price differences. However, the trades can be leveraged 50 times and if funding costs suddenly rise or Treasuries become volatile (as in the pandemic), hedge funds can be in trouble. It's causing regulators a headache.
