FlexTrade Systems is a provider of customized multi-asset execution and order management trading solutions for buy- and sell-side financial institutions. Through deep client partnerships with some of the world’s largest, most complex, and demanding capital markets firms, we develop flexible tools, technology, and innovation that deliver a competitive edge. Our globally distributed engineering teams focus on adaptable technology and open architecture to build highly sophisticated trading solutions that can automate and scale with evolving business strategies.

At FlexTrade, our values guide everything we do. We are dedicated to client success, ownership, flexibility, integrity, continuous improvement, and strong collaboration, while fostering an environment where teams grow together and enjoy the work they do.


Core Application Development Team:

The core application development team works on our main desktop applications: FlexTRADER EMS, FlexONE OEMS, and FlexOMS. This is a highly collaborative and rewarding area, which combines many business functions in one spot. While spending most of the time on development, we also help to resolve and fix issues in client setups and support our client services team.

  • Resolve the complex technical issues and challenges of a multi-asset trading application both independently and in close collaboration with your team
  • Provide guidance and documentation on product features and technical specifications
  • You will spend most of your time working on the underlying implementation of the front end with infrequent excursions into GUI work. This role is flexible enough to find what aspects of our stack you’re interested in and focus on them


What we would like to see from you:

  • Proficiency in C++ programming (cross platform Windows/Linux) with knowledge of the advantageous features of the C++17 and C++20 standards
  • Solid algorithm, data structure, and system design fundamentals with a good understanding of software engineering principles
  • Strong debugging and problem-solving skills
  • Detail oriented and willing to grow into taking ownership of parts of the product
  • Good attitude and appetite to learn and grow


Nice to haves:

  • Experience with debugging tools on both Linux and Windows
  • Experience working with C++ GUI frameworks like GTK or Qt
  • Experience working on networking stacks in C or C++
  • Comfortable working in and maintaining large and legacy codebases
  • Experience with event-driven architectures and system design

OR

  • Equivalent non-academic qualifications (work experience or independent learning)
