Developer/Senior Developer, FlexNOW

Job description

FlexTrade Systems

Founded in 1996, FlexTrade Systems is the global leader in high performance, multi asset order and execution management solutions.

FlexTrade introduced the first trading system that enabled clients to control and customize their proprietary algorithms while maintaining the confidentiality of their trading strategies via a vendor-provided, broker-neutral platform.

Our worldwide client base spans more than 175 buy- and sell-side institutions, including investment banks, hedge funds, asset managers, commodity trading advisors and institutional brokers.

Located in Great Neck, NY with offices in North America, Europe and Asia, FlexTrade maintains an experienced staff of developers, programmers, strategists and product specialists, who work hand-in-hand with our clients' technologists and traders to break new ground in the field of electronic trading.

We offer competitive salaries, bonuses and a comprehensive benefits package.

The Team

The FlexNOW team is building a new, cloud-based EMS platform that aims to shake up and disrupt the industry. We work in a modern, agile way focusing on lightweight processes and rapid feedback backed by a strong DevOps culture. We’re a fast-paced, yet relaxed team who deploy new features releases to production at least 1-2 times per week.

We operate as a multi-functional delivery team, meaning we have everyone we need to deliver the product sitting together – Dev, QA, Ops, UX, Support, Client Relationships and Sales. This reduces friction and allows us to deliver at pace.

Our product is new to the market, so we are still primarily working on new features to make sure we are the best choice for clients. All this gives us a startup feel to the team but as part of a wider company, avoiding the usual pressures startups feel.

Whilst we do support the product as a team, our rapid delivery means that our live environment is very stable so this takes very little effort. 

About You

We are looking for an amazing, flexible and pragmatic developer with some good experience under their belt. You will have worked on a variety of interesting and well-built systems giving you a great perspective on building quality software without over-engineering.

You will have a passion for software development, from coding to CI/CD to the team processes needed to get things done. You will be up to date on modern technology choices, not necessarily because you need them now but because you simply love learning about them. You will have a strong delivery focus, understanding the value of the work you do and how much time and effort should be spent on it. Overall, whilst you have a great love of development, what you enjoy more is getting working software into the hands of people that want it.


  • 3+ years experience as a software developer but we know that number of years isn’t everything so the quality of your experience counts the most
  • Ideally good experience working with .Net technologies including .Net core (although we value good devs over specific language skills)
  • Ability to work on a sizeable codebase and integrate with a modern workflow i.e. agile processes, automated testing, CI/CD, etc
  • Able to constructively review other team members code
  • Not scared to take on aspects of other roles and get stuck in e.g. devops, analysis, qa, etc

Does this sound like you? We would love to hear from you. You can apply on the link on this page and we will get back to you as soon as we are able. For more information visit or follow us on twitter and LinkedIn for the latest updates.
