Senior Software Development Engineer - Elasticsearch

This position is a day rate contract role that will last for 3 months, with the possibility of extending to 6 months. You will lead the engineering work that underpins search in our merchant dashboard 1 the primary interface through which thousands of businesses manage their customers and payments on GoCardless.

Search is a critical workflow for our merchants. Whether they re locating a specific customer, tracking down a payment, or reconciling transactions, they rely on search to get to the right information quickly. You will design and implement a robust, high-quality search solution that meets these needs: relevant, fast, and resilient at scale.

This is a hands-on engineering role. You will work closely with our Product Engineering and Platform teams, contributing production-ready code and pairing with engineers throughout the engagement. A key measure of success will be how well-equipped the team is to maintain and evolve the system after you leave.
