• Collaborate effectively with cross‑functional teams, including Group IT Architecture and global stakeholders to deliver integrated solutions.
• Champion best practices in software engineering, including OO principles, SOLID design, and CI/CD pipelines.
• Research and evaluate emerging technologies, particularly in the DBT and data engineering space, to keep our stack cutting‑edge.
• Optimize performance and scalability across microservices and data pipelines.
• Mentor and guide junior developers, fostering a culture of continuous learning and improvement.
• Troubleshoot and resolve complex technical issues, ensuring minimal disruption to business operations.
• Contribute to architectural decisions, influencing the future direction of our platform and data strategy.
• Communicate clearly and proactively, translating technical concepts into business‑friendly language for stakeholders.
• Promote an automation‑first mindset, identifying opportunities to streamline processes and reduce manual effort.
• Ensure security and compliance in all development activities, adhering to industry standards and internal policies.
