Software Engineer

LDN Summer Internship

About the Programme

Our internships center around hands-on mentorship and a robust educational curriculum that includes challenging classes, interactive sessions, and small group discussions. Over the course of 10-12 weeks, you’ll be matched with full-time employees in your role who will mentor you as you tackle real-world projects they design. You’ll also be able to access our physical and virtual educational resources, attend guest speakers and social events, and hopefully get a real sense of what it would be like to work here full time.

If you’ve never thought about a career in finance, you’re in good company—many of us were in the same position before working here. If you have a curious mind, a collaborative nature, and a passion for solving interesting problems, we have a feeling you’ll fit right in.

About the Position

As a Software Engineering intern, you’ll learn how we use OCaml (our primary development language) in our day to day work, and gain exposure to the libraries and tools that are foundational to our internal systems.

During the programme you’ll work on two projects, mentored closely by the full-time employees who designed them. Some projects consider big-picture questions that we’re still trying to figure out, while others involve building something new. Your mentors will work in two distinct areas, so you’ll gain a better understanding of the wide range of problems we solve every day, from machine learning to systems administration to programming language design.

About You

We don’t expect you to have a background in finance, OCaml, functional programming, or any other specific field—we’re looking for smart people who enjoy solving interesting problems. We’re more interested in how you think and learn than what you currently know. You should be:

  • A top-notch programmer with a passion for technology
  • Collaborative and courteous with strong interpersonal and communication skills
  • Eager to ask questions, admit mistakes, and learn new things
  • Fluent in English
