They do pay extremely well, but are also very selective. The kind of talent they are looking for can earn similar salaries at large tech companies like Google ($400K-500K TC is pretty common at staff+ levels).

a high performer at citadel or JS can make 1m in 5 years. i don't know many people at google make that much.

Citadel has 2600~ people, Jane street 2000~ while google has 150,000~.

Do you have a source on the $1mn+ figure? I would be curious to read more about this.

I mean, not really. This is personal knowledge. You can't really look up salaries because the base is like $175k but even in mediocre years they're getting high six-figures in bonus. Take a peek at what Wolverine, Radix, or Jump are paying new grads though. It's generally like $500k+. Even Jane Street, which is a larger place that hires people who aren't published mathematicians (see: Sam Bankman-Fried) pays $750k

Yeah the numbers he posted were also base from JS and Citadel websites, so they're not reflective of how much one could (or even guaranteed will with the early career bonus floors) actually make at those places.

This is for traders and researchers though. You can get pretty similar early career salary + bonus as a SWE at JS or Citadel, which is probably what more people on HN would be considering. Do you know what kind of pay the smaller shops offer for pure SWE?

The context here is that Sam Bankman-Fried of FTX and a number of the other executives (Caroline Ellison and Brett Harrison) were previously traders at Jane Street. This video is from 2017, a couple of years prior to the FTX launch. It makes you wander if any of them were in attendance.

While I wouldn't be surprised to see some proactive PR from the company in the wake of recent events, perhaps including the post on the zkSNARK competition last month; which was in my humble opinion one of the few submissions that has truly moved me since the late 2000's on this site: I feel obliged to attest that the people I knew working at Jane Street at that time were some of the straightest shooters one could kn…

Can you link zkSnark convo mentioned here?

Really? Isn't FinTech getting hit harder than just about any other industry right now?

First, i dont consider Citadel, JS, etc "fintech" because they are not in the same line of work. " Fintech, a portmanteau of "financial technology", refers to firms using new technology to compete with traditional financial methods in the delivery of financial services. " This is NOT what people like CIT, JS, etc. do. So maybe FinTech is being hit very hard, but from what i hear Cit, JS are doing just fine (no real l…

Haha yea FinTech would be a pretty derogotory term to call a HFT firm

I’m afraid that’s out of my purview. Only familiar with quant traders and researchers.

I’m sure it’s as good or better than big tech. But you don’t get to live in San Francisco and the work is a lot more boring.

Yeah, as an exchange FTX was pretty terrible. The matching engine was notorious for being high latency, unreliable, and having all sorts of undocumented issues. Every algo trader there will tell you horror stories about trying to cancel an open order, getting a cancel confirmation, then getting notified that the order was executed. Sometimes seconds later. What really gave FTX a competitive advantage was its cross-ma…

The main advantage of FTX's exchange was that it was far better than Binance's but that's barely saying anything. I'm not sure why crypto exchanges have such lousy technology. Lost acks, weird parser errors, missing order id fields, sessions giving no indication that the matching engine is down, etc. It seems like any conceivable way an exchange can break will be encountered after only a couple months of trading. It'…

Because it was all a scam and didn't need to polish details ?

I agree that Two Sigma, Jane Street, Renaissance, etc. are NOT Fintech. Fintech is a really large umbrella which seems to includes people like Paypal or Bloomberg and things like robotraders or companies that deal with some financial product. Hedge Funds / HFT / Algo traders can be really sophisticated with their technology, but I wouldn't call them "Fintech".

@dang could we get a (2017) added to this? Changes the context quite a bit given FTX folks worked at Jane Street previously and a modern version of this talk would have a much different context.

FTX's Gary Wang worked at Google.

It's intriguing how Forbes 400 list includes criminals. If someone tricks people into "investing" with them and they accumulate enough billions of US dollars, and it takes a few years for the authorities to act, then do they get a spot on the Forbes 400. What are the rules.

I don't think the context changes at all. This talk is about high performing systems (millions of requests per second) written in OCalm. There is nothing here related to the criminality of FTX or what its non-technical founder decided to do with customer funds as a business decision. It matters very little that one or more of them used to work as an analyst at Jane Street.
