Five Rings Quantitative Researcher Internship 2027

A nine-week paid summer internship in New York on the research side of Five Rings, a proprietary trading firm with offices in New York, Boca Raton, London and Amsterdam. Interns work closely with the research team on development projects and are given a mentor fully dedicated to them for the duration, alongside classroom instruction, in-house built strategy games and a series of talks introducing key trading concepts. The 2027 programme runs from the beginning of June to the beginning of August.

You need to be working towards one. The posting states that candidates must be working towards a PhD in computer science, mathematics, physics, statistics, economics, or another qualifying field, and the official job title carries PhD in brackets. Master's and undergraduate students should look at the Five Rings quantitative trader internship, which sets its bar by expected graduation date between winter 2027 and summer 2028 rather than by degree level.

The posting lists an annual base salary of $300,000, the same figure as the quantitative trader internship. Because the programme runs nine weeks, that annualised number works out at roughly $52,000 for the internship itself. Interns also receive a sign-on bonus and corporate housing in New York, which matters more than it sounds given how expensive and difficult short-term summer accommodation in the city is.

The posting does not say, and that silence is the point. The sibling quantitative trader listing states directly that students outside the US are eligible to apply, and this researcher listing carries no equivalent sentence. Both application forms ask whether you are legally eligible to work in the US and whether you would require sponsorship now or in future. International PhD candidates should answer accurately and ask a recruiter about sponsorship rather than reading the trader policy across.

Four things. The researcher role requires working towards a PhD, while the trader role is set by graduation date and takes undergraduates. Researchers sit with the research team on development projects, traders with the trading team. The trader programme includes mock trading, which does not appear on the researcher listing. And the trader posting welcomes applicants from outside the US, while the researcher posting is silent on it. Pay, length, location and the housing package are the same on both.

Basic programming experience through internships or academia is listed as a requirement rather than a preference. Five Rings is not asking for a software engineering background, but research at a trading firm is done in code, so your CV needs to show the languages you use and something concrete you have built with them: a simulation, a solver, an analysis pipeline, a package for your own field.

No deadline appears on the posting. Quantitative trading firms recruit on a rolling basis and close a requisition once the cohort is full, which in practice means the season runs from late summer through autumn for the following summer. Treat the absence of a date as a reason to apply in September or October rather than as permission to wait until the new year.

The posting does not describe the stages, but quantitative research recruiting follows a recognisable pattern: probability, statistics, linear algebra and stochastic processes, coding exercises, and a serious conversation about your own thesis work. Expect to derive results rather than recall them and to defend the modelling choices in your research. The posting's emphasis on wanting people hungry for the hardest problems is a fair signal of the depth involved.
