About:

This is one of the world’s largest market-makers, trading more than $17 trillion securities. An incredibly tech-focused company, they hire some of the best developers from around the world (open to any coding language background). Well-known users of OCaml and a large open-source presence means engineers here can see their code being utilised as part of these huge trades, as well as having a life beyond the company in the developer community – one of the main draws for the many engineers that have joined from both tech and other financial firms.

• Engage in projects that range from machine learning to systems administration and beyond.

What They’re Looking For:

• Programming Skills: Top-notch programming abilities in any object-oriented (OO) language. While they primarily use OCaml, experience with functional programming is not required.
• Passion for Technology: A deep love for and understanding of technology, with an interest in diverse areas like programming language design, systems engineering, and more.
• Collaboration: Strong interpersonal skills to work effectively within small teams.

About You:

Candidates from any OO programming background who are eager to learn new languages and technologies are welcome. No prior experience in finance is necessary; they are more interested in your problem-solving skills and your ability to learn.

Why Apply:

• Work in a high-impact role with a direct influence on business outcomes.
• Be part of a team that values autonomy and responsibility, offering a broad perspective on how the business operates.
• Engage with a company that values open-source contributions and innovative technology.
