Software Engineer (Golang) – Telco Experience

About the position As a Software Engineer in the Telco Experience Team, you’ll help build and integrate APIs that power stakeholder-facing telco journeys, working closely with product managers, frontend engineers, and business stakeholders to deliver customer-focused features. While this role sits within our Telco Experience Team to meet immediate hiring needs, we’re also growing our engineering function more broadly and are keen to hear from engineers interested in building products across multiple domains. We value solid engineering fundamentals and transferable skills, and you’ll have opportunities to work beyond telco as our platform and teams continue to scale. You’ll collaborate with core platform teams responsible for supplier integrations and shared infrastructure, contributing to projects that shape how our telco products are experienced end-to-end. You’ll work primarily with Go, Kafka, Kubernetes, Postgres and MongoDB, gaining hands-on experience with event-driven systems and modern observability practices. We're looking for a backend-focused engineer who enjoys learning, collaboration, and contributing to frontend-heavy initiatives while building reliable services. You’ll thrive here if you’re curious, proactive, and comfortable working in a fast-moving, evolving team. Experience in regulated consumer services or consultancy, and an interest in digitalisation and whole-product thinking, are a plus, but above all, we value a growth mindset and a desire to build great customer experiences together.
