Lead Frontend Developer

Technical leadership across modern financial markets technology

Exceptional React engineering ability remains essential

Line management responsibility, including around two to three team leads

Client facing and commercial responsibility

Permanent employment contract only, no B2B

Salary flexible for exceptional candidates

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.

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.
