Optiver - Low latency C++ workshop

Patrick Kostjens

21 October 2021, 17:30 CEST

Do you want to learn how to write the fastest and best performing code possible? Are you ready to dive into assembly, cache internals and squeeze the last nanosecond out of your code? If so, then join our low-latency workshop on code optimisation!

During this workshop one of our engineers will demonstrate some of the profiling and micro-benchmarking techniques used when developing low-latency code. Through concrete code examples, we will share some of the performance tips and tricks attained from our vast experience in writing fast, maintainable and modern C++ code. We will look into assembly generated by the compiler to understand how seemingly small code changes affect the work a processor needs to do.

Jane Street's Upcoming Tech Talks

You are invited to attend the following talks:

Tuesday, October 12th 2021

17:00-18:00 BST / 18:00-19:00 CEST 

Title: Feedback Directed Optimization for OCaml

Speaker: Greta Yorsh

OCamlFDO is a tool that uses information about frequently-executed program parts to guide compile-time optimization decisions. Code layout optimization is a classic example of why this information is useful, how hardware and compilers interact, and how (not to) measure performance. In this talk, we will explore the design of OCamlFDO and how it was influenced by practical needs to fit in with different built systems, developers' workflows, and the open-source compiler itself.

Speaker Bio:
Greta Yorsh works on OCaml compiler here at Jane Street, having previously worked on GCC compiler at ARM. She is passionate about low-level optimizations that present the combined challenges of ensuring correctness and achieving the best possible performance on modern hardware. She studied Computer Science at Tel Aviv University and has been involved in several academic and industrial research projects in the areas of software verification, program synthesis, and superoptimization.


Thursday, October 14th 2021

17:00-18:00 BST / 18:00-19:00 CEST 

Title: Algorithmic challenges in build systems and incremental computation

Speaker: Andrey Mokhov

Build systems are used by every software developer on the planet, but they are far from being a solved problem. For years the venerable Make dominated, but more recently the challenges of scale have driven large software firms to develop their own build systems, such as Google's Bazel or Facebook's Buck. Jane Street is not as large, but we are not in exception; in fact, we developed not one, but two build systems! In this talk, you'll learn about the build system called Dune and about the incremental computation library that powers it. As an example of a tricky algorithmic problem that we recently needed to solve, we'll look at concurrent cycle detection in build graphs comprising millions of nodes.

Speaker bio:
Andrey Mokhov works in Jane Street's build systems team, trying to keep our build times under control despite the rapidly growing population of software developers. Before joining Jane Street, he was an academic researcher at Newcastle University (UK), working on asynchronous circuits, functional programming, and build systems.

Please RSVP to either, or both of these talks using the link below by Sunday 10th October at 23:59 BST. 

Final information including dial in details will be sent on Monday 11th October.

Jane Street is currently actively recruiting for our 2022 Summer Internship in Software Engineering. To find out more and apply. Click here.

This event will look to give some general tips on CV writing and interview techniques, and offer some one-to-one sessions with our recruitment team.
In the one-to-one sessions we can discuss your questions around any roles you're interested in, at G-Research or otherwise. Your session could include a personal CV review, a run through of interview best practice, or anything about general job applications.

If you are interested in attending, please fill out your details before 12pm on Wednesday 6th October, here:


Student Coding Challenge:

Join us for the G-Research Coding Challenge, where we'll have multiple teams from universities across London compete in a series of progressively more difficult software development challenges.

Tuesday 22nd November, 6:00 - 8:00 pm (GMT)

Open to all CompSci/Mathematics students, the event will have teams of up to 5 people competing to build a natural language calculation engine (no prior NLP experience required). The challenges will cover things like evaluation of arithmetic expressions to unit conversions and equation solving.

To register, fill out the form at

We will be allocating teams the day before the event, so please ensure you have registered by 12pm on Monday 21st November. If you would like to join as a team with friends, please email

Once you have registered you will receive a unique link to join the event which you should use to log in by 5:45 pm (GMT), so that you can meet your teammates and learn how to navigate the online event space. More information on the event will be emailed to you one day before.

Once the game is complete, you will have the opportunity to stay online for some virtual networking where you can discuss the event and life at G-Research with members of our team.

We'll be handing out prizes to the top three teams, with each member getting an Amazon voucher (£100 for first, £50 for second, £20 for third).


Palantir Fall Events

We will be hosting a series of virtual events throughout the fall for students to learn more about Palantir’s work, opportunities and to prep for applying to open positions. This page will be continuously updated, so please do check back throughout the fall! Once students either RSVP for an event or submit an application, someone from the recruiting team will reach out with next steps.
