Build systems that power trade execution for millions of investors
HL Tech is the technology hub of Hargreaves Lansdown, a privately owned UK financial services group trusted by approximately 2 million clients and supporting more than £172 billion in savings and investments.
We are part of HL's product and engineering organisation, not an outsourcing company or shared service centre. Our teams in Poland and the UK jointly design, build and run the platforms used by HL clients.
You will join Trade Execution, the team responsible for systems connecting clients with financial markets, including trade routing, order execution and broker integrations. The role combines new development with the modernisation and support of established trading components.
What makes this role different?
Your work directly supports trade routing and execution for millions of investors.
Own services end-to-end, from design and implementation through deployment, monitoring and continuous improvement.
Work with distributed, highly available and event-driven systems where reliability and observability matter.
Contribute to technical decisions, service boundaries and implementation approaches, not just feature delivery.
Help modernise an established trading platform while building new functionality.
Work directly on HL products in a collaborative Poland-UK engineering team.
We are looking for engineers who take ownership beyond delivery, enjoy solving production problems and care about reliability as much as they care about building new features.
