About the Role

We are actively seeking an experienced client-facing front-office electronic trading technologist for a unique opportunity to join our sales team working with across our suite of highly customisable order and execution management systems used by some of the largest institutions in the world.

As Senior Sales Engineer your primary responsibility will be to ensure the sales team can demonstrate our product’s full capabilities and breadth of function across all supported asset classes and workflows.

You will be responsible for developing proof-of-concepts for both prospective clients, and in-house subject matter experts, as well as drawing on your own technical and electronic trading experience.

You will collaborate with 3rd party vendors and brokers, to incorporate their services into our product, to ensure we are continuously improving and extending our products.  Everything from vendor research, outreach, through to workflow design and implementation, and eventual production deployment is included.

Ideally, you should be confident to take your own initiative around product direction and join the sales team in pitches as technical consultancy.

Ultimately, this role is crucial to maintaining FlexTrade’s position as a best-in-class trading system and will directly contribute to the overall success of the business.
