ABOUT THE CLIENT

You will be joining a major engineering programme for a global financial technology business modernising the infrastructure behind institutional trading and capital markets.

Much of the financial industry still relies on technology built decades ago. This organisation is helping replace that legacy infrastructure with modern, cloud native systems built around real time data, scalability and the demands of today's global markets.

The technology operates across sophisticated areas of the financial markets, creating an engineering environment where performance, reliability and technical quality are fundamental.

This is a technology led environment with an exceptionally high engineering bar.

THE ROLE, PRINCIPAL REACT ENGINEER

This is more than a very strong React individual contributor role, but it is not a conventional Engineering Manager position either.

You need to remain technically credible with exceptional React engineers while taking responsibility for people, delivery and senior client relationships.

From a leadership perspective, you will line manage engineers, including around two to three team leads, help decide how engineering capability is deployed and become involved when difficult delivery or client issues need resolving.

You will also work closely with account management and carry genuine responsibility for the success of the engagement.
