We're part of a 400-person global company, but the UK team operates with startup energy: small enough that your work is visible, big enough that you're backed by serious investment.

What You'll Need • 6+ years of professional software engineering experience, with significant experience designing and operating backend services, distributed systems, and system integrations. • Demonstrated technical leadership on complex engineering projects, including architecture, design reviews, implementation strategy, and mentoring other engineers. • Strong hands-on experience with APIs, webhooks, asynchronous messaging, data pipelines, and technologies relevant to our stack such as Java, TypeScript/JavaScript, RESTful services, SQL/MySQL, and cloud-native systems. • Experience leading engineers through a mix of technical direction, coaching, project leadership, and people management, with the judgement to know when to guide, delegate, or step in directly.
