MGNR | Senior (Quant) Developer | Full-time | Remote (worldwide)

MGNR is a small, highly successful proprietary trading firm. Our fully-automated trading system executes hundreds of thousands of transactions every day, totaling billions of dollars in volume. Our team (currently 10) is fully distributed across many timezones and came together over the past three years. Our tech stack is a microservice-based architecture hosted in the cloud (AWS), written primarily in Rust and some Python.

We are looking for a senior (quantitative) developer to take ownership of everything performance-related at the company. The role will consist of two aspects:

(i) War on latency: Use every trick in the playbook to improve the speed with which our system reacts to information. Optimize our software, hardware, and network topology to minimize our reaction time across all percentiles. Build the instrumentation necessary to monitor our system performance, identify bottlenecks, and squash them.

(ii) System Architecture: Design and implement robust trade gateway frameworks as we expand our trading to new venues and roll out new strategies.

Desired skillset: experience in a low-level programming language (ideally Rust), strong understanding of Unix and network protocols, a keen eye for benchmarking and tuning critical software services to achieve maximum performance, knowledge of exchange architectures, and a passion + understanding of the markets and trading

Competitive salary and bonus, flexible work hours, no customers to please, result-driven no-bullshit tight knit team, flat structure, no commute, lots to love.

How The Economic Machine Works by Ray Dalio

https://www.youtube.com/watch?v=PHe0bXAIuk0

I don't agree entirely but good signal-to-noise ratio on this content


That's not bad intro, but it's very rudimentary. It has necessary errors of omission. It really don't teach teach how economy works

Btw. his site https://www.economicprinciples.org/ has good reading if you scroll down below the video.


"Ray Dalio says 'cash is trash' and advises investors hold a global, diversified portfolio" - Jan 21 2020

Had you have listened to him, you would have just been taken out back, shot, and put in one of wuhans finest crematoriums… better off reading "Statistical Consequences of Fat Tails"[0]

[0] https://arxiv.org/abs/2001.10488


His advise is still sound if you are an investor and not speculator.

The part of your investment that is in stock should be determined your investment horizon. If you don't need to sell your stock in next 15 years, don't hold cash.


Yeah, would have played out very well for those top ticking n225 in 1989, esp with every global CB's trying to follow in the footsteps of the BOJ, while everyone is crowding into "diversification" and searching for yield…

I consider investors to be the same as speculators, just speculators who think their beliefs will remain valid over long time frames… cause that's the gamble.


investor who does

- dollar cost averaging,

- diversification, small cost investing,

- has sufficiently long time-horizon

has never lost money on 15 year timescale, at least past WWII.


Even assuming that's true, one can't say the sort of risk and investor took on 15 year look-backs since WWII has been evenly distributed to get some sort of acceptable return, nor can one say that this will continue hold true for the next 15 years. You may believe it hold true though, and many do… but very few will do their homework on the risks to their "diversification" and their own changing liquidity constraints that will occur over the "sufficiently long time-horizon"


> assuming that's true,

Don't assume. You can calculate it in spreadsheet.

> You may believe it hold true though,

In the long run we are all dead. We don't need to believe they hold true. Certainty is not part of this world. Because you never know is just rhetorical argument. Quantifying risk and going on that is good enough.


>Quantifying risk and going on that is good enough.

Because most people who are blindly buying indexes around the world thinking they are diversified and DCA are certainly doing that…


So if you don't believe in investing then what are your plans for retirement? Just to save enough money into a bank account?


I didn't say I didn't believe in investing, just that I don't consider it any different from speculating, just the time frame typically involved.


> ...except the transactions come first...

one need to buy a ticket _before_ boarding the train

here the ticket is Tether, and the train are exchanges (mostly Bitfinex)


Except the circular argument that their ticket is bought because of optimism, that is created by them buying the ticket... hence the chicken-egg statement in the article.


With all due respect, requests to BitMEX during times of high load have >50% probability of hitting a 503 Service Unavailable error. Meanwhile, competitors with similar volume/activity don't have this problem.


They've done studies, you know. They say 60% of the time, it works every time.
