Developer Experience Engineer – DevEx

Role Overview

• Design, build, and maintain Arbor’s Internal Developer Platform (IDP), providing self-service tooling, consistent build pipelines, and standardised deployment workflows.
• Develop project scaffolding and templates that allow engineers to rapidly bootstrap new services with best practices built in.
• Integrate core engineering systems (CI/CD, observability, service catalogue, documentation) to provide a joined-up developer experience.
• Collaborate with the Platform Engineering and DevSecOps teams to ensure the IDP embeds security scanning, dependency management, and compliance controls by default.
• Embed AI-assisted tooling (e.g. Claude Code, Codex etc) into the developer workflow.
• Partner with the Head of Developer Productivity to define and measure AI efficiency metrics.
• Develop plugins, workflows, or integrations that help engineers use AI tools safely and effectively.
• Contribute to the continuous improvement of AI onboarding, training, and developer enablement.
• Consolidate and rationalise the engineering toolchain, ensuring consistency across teams.
• Build automations and command-line utilities to streamline repetitive development tasks.
• Maintain and improve shared build/test/deploy templates and scripts.
• Collaborate with teams to identify pain points in the development lifecycle and propose solutions.
• Collaborate with DevSecOps to build and maintain reusable secure coding templates, CI/CD guardrails, and compliance checks.
• Contribute to the collection and reporting of developer productivity data (e.g. build times, PR cycle times, deployment frequency).
• Support automation and observability for key developer metrics.
• Participate in post-implementation reviews to quantify the impact of new tooling or process changes.
