• Deliver roadmap features end to end, from technical planning and implementation through testing, deployment, and ongoing maintenance.
• Apply an AI-first development approach using Claude Code or similar AI coding agents to accelerate implementation, improve productivity, and support high-quality software delivery.
• Use agentic coding workflows to plan tasks, generate and review code, automate development activities, and validate AI-generated solutions against established engineering standards.
• Refactor and improve existing codebases and architecture to make systems more maintainable, reliable, and accessible to AI coding agents.
• Participate in the Content Layer Service Desk and internal request boards, investigating issues, resolving service requests, and supporting operational continuity.
• Write and maintain automated tests to ensure application reliability, prevent regressions, and validate new functionality.
• Participate in peer code reviews, share technical knowledge, and promote clean, maintainable, and well-tested code.
• Maintain and improve CI/CD pipelines to support reliable deployments, shorter feedback cycles, and continuous delivery.
• Collaborate with engineers and relevant stakeholders to understand requirements, troubleshoot technical challenges, and deliver solutions aligned with business needs.
• Contribute to continuous improvements in development workflows, production support, and AI-assisted engineering practices.

Requirements

• Between two and five years of professional experience in backend or full-stack software development.

• Experience writing automated tests, participating in code reviews, and working with CI/CD pipelines.
• A proven track record of delivering reliable, high-quality features to production and taking responsibility for their ongoing performance.
• Strong analytical and problem‑solving skills, with the ability to investigate issues and develop effective technical solutions.
• Excellent written and spoken English skills, enabling clear communication and effective collaboration within an international, distributed team.
• A proactive, independent working style, with a strong sense of ownership and a willingness to learn and experiment with emerging development tools.

Nice To Have

• Deeper knowledge of AI coding agent capabilities, including skills, Model Context Protocol (MCP) servers, subagents, and context engineering.
• Experience with Kafka or other message brokers and event‑driven architectures.
• Familiarity with Docker, Kubernetes, Amazon EKS, and AWS infrastructure.
