As the Lead Developer Experience Engineer, you'll be the technical anchor for our Internal Developer Portal - the platform that 600+ engineers rely on every day to discover capabilities, scaffold new services, and adopt platform best practices. Right now, this is the highest-leverage investment our Cloud Platform Engineering team can make. You won't just build a portal, you'll shape how developers work across the entire organisation, turning complex platform capabilities into an intuitive, self-service experience. This role is for someone who thinks deeply about user experience, can bridge frontend and infrastructure engineering, and wants to have a real impact on how a scaling engineering org works.

• Lead day-to-day development of the Internal Developer Portal: feature delivery, plugin development, catalogue design, and integration with platform APIs. You'll ship code, not just plan it.
• Build and maintain plugins that surface platform capabilities - infrastructure-as-code modules, CI/CD pipelines, shared services, observability dashboards, SLO definitions - as discoverable, self-service catalogue entries.
• Own the portal's component model: how services, APIs, resources, permissions, systems and golden paths are represented, related and presented to developers.
• Collaborate with Cloud Platform Engineering teams and product engineering to design and build self-service facilities that take developers from 'I need a new service' to a deployed, observable, SLO-defined service without manual work.
• Anchor the technical standards for the DX & Portals team: code review quality bar, plugin development patterns, frontend testing, accessibility and portal performance. Mentor DX Engineers joining the team and provide technical guidance on architecture and decision-making.
• Listen to developer feedback through surveys and conversations, continuously improve the portal and drive adoption of platform standards. Work with the Director to prioritise features and eliminate friction.

• Software engineering experience, including developing and deploying high-availability services to production.
• Strong experience with a modern frontend framework (React, Vue.js, or equivalent) and solid understanding of backend service patterns, ideally including Java.
• Familiarity with cloud-centric tooling: infrastructure-as-code (Terraform), CI/CD pipelines (GitHub Actions or equivalent), Kubernetes, and cloud platforms (GCP, AWS, or Azure).
• A product-thinking mindset: you design around user needs, treat platforms as products, and focus on adoption and feedback loops.
• Experience mentoring and leading engineers; you can set a technical quality bar and help others grow.
• Strong technical writing and communication skills. You can explain complex systems clearly and document decisions so others understand the reasoning.
• A Bachelor's or Master's degree in Computer Science, Engineering or related field, or equivalent professional experience.
• Experience building or contributing to developer platforms, Internal Developer Portals, or other internal tooling at scale (preferred)
• Exposure to platform engineering concepts: CI/CD, observability, SRE practices, and golden paths (preferred)
• Experience working with SaaS platforms for building developer portals or similar configuration-driven tools (preferred)
