• Champion engineering excellence through clean, maintainable and well-tested code, promoting best practices through code reviews, pair programming, documentation and continuous improvement initiatives.
• Drive operational excellence and observability by designing effective monitoring and alerting, leveraging tools such as Dynatrace and participating in support activities to ensure critical supply chain and pricing data remains available and accurate.
• Collaborate closely with Product Managers, Engineering teams, Supply Chain and Commercial stakeholders to solve complex business problems and accelerate value delivery through effective cross-functional working.
• Mentor and support colleagues by providing coaching, technical guidance and feedback, helping to grow engineering capability and foster an inclusive, high-performing engineering culture.

Who You Are

Your skills and experience will include:

• Significant experience building and scaling data-intensive distributed systems, ideally supporting large datasets, high transaction volumes and mission-critical business processes.
• Strong proficiency in JVM-based technologies, particularly Java, with experience developing scalable backend services and ideally working with Micronaut.
• Hands-on experience implementing DevOps practices, CI/CD pipelines and engineering automation, including tools such as GitHub Actions and Infrastructure as Code technologies like Terraform.
• Strong knowledge of cloud platforms, preferably Azure, alongside modern data integration technologies including Kafka, SFTP, relational databases, MongoDB and SaaS integrations.
• Experience designing data models, data contracts and schema evolution strategies, with a strong understanding of domain-driven design and enterprise integration patterns.
• Ability to balance strategic thinking with pragmatic delivery, making effective technical decisions that meet both long-term architectural goals and immediate business needs.
• Strong focus on software quality, security and operational excellence, with experience using tools such as Snyk, Semgrep and other modern security and code-quality platforms.
• Interest and practical experience in AI-assisted development, leveraging tools such as GitHub Copilot and Claude to improve productivity while maintaining engineering quality.
• Broad engineering awareness across the full technology stack, including an understanding of frontend technologies such as React and Angular to support effective collaboration across teams.

Desirable Experience
