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.

This is a hybrid role requiring in person work 4 days per week in our Great Neck or NYC offices with one flexible remote day.

What will you be doing:

  • As a member of the development team, you will be responsible for designing and implementing solutions in the FlexTRADER EMS, FlexONE OEMS, and Sell Side FlexOMS products

  • Work closely with client services and implementation teams to provide new features and fixes to clients

  • 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
