Develop a deep understanding of upstream and downstream systems to maintain end‑to‑end data quality, proactively identifying risks, resolving root causes, and preventing data‑induced defects.
Break down ambiguous technical problems, identify root causes across complex systems, and deliver incremental improvements with clear milestones.
Collaborate with cross‑functional partners across product, design, platform, security, and data to ensure system accuracy, streamline interactions, and drive continuous improvements to reliability, performance, and customer experience.
Establish and champion engineering best practices, mentor engineers, driving measurable improvements across SCORP engineering excellence pillars.

Experience building and optimizing cloud‑native platforms using modern cloud services (preferably AWS), CDK, DevOps practices, GitHub Actions or equivalent CI/CD platforms, and infrastructure automation.
