The posting

About the team We are a small, collaborative software development team supporting market-making and brokerage systems. The role’s primary responsibility will be maintaining and improving an automated market-making process. In addition, you will contribute to a variety of backend development projects across the brokerage environment. These projects may involve improving existing applications, investigating issues and developing new functionality. Our systems are primarily written in C++ and run on Linux. What you’ll do

Maintain, enhance, and support an automated market-making application Develop and maintain C++ and python backend applications and services used in brokerage-related systems. Investigate issues in existing software, identify root causes, and implement reliable fixes. Use AI-assisted development tools, such as Claude and Codex, responsibly to support design, implementation, testing, debugging, and code review. Write clear, maintainable, and well-tested code. Work primarily in a Linux environment using GCC and common command-line development tools. Collaborate closely with other developers and stakeholders to understand requirements and deliver practical solutions.

What we’re looking for Required

Good programming ability in C++ appropriate to your level of experience. Understanding of object-oriented programming, common data structures, algorithms, and the C++ Standard Library. Strong logical and analytical problem-solving skills. Ability to read, understand, debug, and improve an existing C++ codebase. Familiarity with Linux or a strong willingness to work in a Linux-based development environment. Familiarity with version control. Care and attention to detail, particularly when working on systems that support trading and market-making activity. Ability to communicate clearly, ask good questions, and work effectively as part of a small team. Willingness to take ownership of tasks and follow them through to completion. A degree in Computer Science, Mathematics, Physics, Engineering, or a related field—or equivalent practical experience.

For junior candidates

University-level knowledge of C++, object-oriented programming, data structures, algorithms, and the STL is sufficient. Relevant personal, academic, internship, or professional programming experience is welcome. You should be eager to learn from an existing codebase and develop your skills in production software development.

For mid-level candidates

Professional experience developing and maintaining C++ applications. Experience debugging production issues and working with existing, long-lived codebases. A practical understanding of software design, testing, performance, and maintainability. Ability to work independently on well-defined tasks while knowing when to involve others.

Nice to have

Experience with financial systems, trading systems, market making, prediction markets, or other data-intensive backend systems

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
