Our technology and resources are combined to build a single, powerful platform for researching algorithmic trading strategies. We use rigorous scientific methodology, robust statistical analysis, and pattern recognition to analyse an extensive and varied financial data ecosystem, extracting deep insights from truly massive datasets. Our platform provides the ability to test your mathematical models in action and get instant results using real world data.

Fabian - Quantitative Researcher

"Before joining G-Research, I completed an Applied Mathematics PhD at Oxford, where I worked on modelling flows of customers inside supermarkets (in collaboration with Tesco). As a Quantiative Researcher, I work on producing forecasts of market returns using mathematical models and various data feeds.

The two biggest things that I like about working at GR are the smart and incredibly friendly colleagues as well as being able to strike a really good work-life balance (in contrast to a lot of the finance industry)."



Annie - Software Engineer

"I was 2 years into my BA in Computer Science at Cambridge when I first joined G-Research as an Software Developer Intern. I then came back to G-Research after I finished my degree, returning to the data development division as a Software Developer.

I first came across G-Research at a careers fair, where I was looking for something to fill my summer and get some valuable experience. After interning here for three months I knew that I wanted to come back.

I love the fact everyone continues to learn and adapt with the changes in technology. You have the freedom to try out new technologies and find the best fit for each application. The company is also very sociable, with monthly company drinks, a summer ball, and an annual weekend away, which is a great way to meet other people around the company. This creates a very friendly work environment. "



Ross - Cloud Engineer

"I studied Computer Network Management and Design at the University of Portsmouth, following this I worked at a small UK hosting company for several years, running their OpenStack-based public cloud platform. I’ve been at GR for around 18 months and in this time I’ve been solely focused on engineering and operating an internal compute platform based on open-source software. 

My favourite thing about working at G-Research is the people. G-Research strive to hire not only the brightest minds, but good people, which in turn creates a brilliant collegiate and social atmosphere at the company."



Charlotte - Security Support Specialist Team Lead

"I studied Forensic Computing and Security at Bournemouth University and completed a placement year here at G Research in the Security Operations team.  I knew GR had access to a lot interesting and innovative technologies so I was very excited and pleased when I received the internship. After a successful year on placement, I was delighted to be offered a graduate role when I completed my degree.

Being a part of a central support team means you get to learn about multiple areas of the company and see what others teams are involved in. It’s the people here at GR which make it an amazing place to work, everyone is very helpful and nothing is too much trouble. With new technology being developed all the time there’s so many new projects to be involved in and always more to learn. "

    Positive Experience
    Average Interview


    I applied online. I interviewed at G-Research.


    It was a video conference with one person. They asked me about my research (I am a PhD student), why I want to go into finance, then asked some math/statistics questions, then asked a programming question.

    Interview Questions

    • - How would you approximate sqrt(110)?
      - Describe linear regression, in particular what it is optimizing.
      - What would be the best fit line for the points (0,4), (2,4) and (2,6)?
      - There is a group of n people, and you are given a function know(i,j) that outputs True if person i knows person j. Note that this is not necessarily symmetric, i.e. person i may know person j, but person j may not know person i. A celebrity is a person that everyone knows, but who knows no one else. Write a function that outputs a list of all the celebrities.   Answer Question
