• Work with Databricks to develop, optimize, and operate large-scale data-processing workloads.
• Develop cloud-native applications and data-processing solutions using AWS.
• Work closely with architects to translate solution designs and technical requirements into production-quality software.
• Contribute to technical design discussions and recommend implementation approaches based on performance, scalability, reliability, and maintainability.
• Implement deterministic and probabilistic matching logic, fuzzy matching, data normalization, identity linking, and related Identity Resolution capabilities.
• Optimize application code, Spark workloads, SQL queries, and data pipelines for performance and scalability.
• Troubleshoot complex application, distributed-processing, data-quality, and production performance issues.
• Develop automated tests and validation processes to ensure the accuracy and reliability of identity-matching logic.
• Build monitoring, logging, metrics, and observability into production applications and data-processing workloads.
• Participate in code reviews and help establish strong software engineering practices across the team.
• Mentor junior and mid-level engineers and provide technical guidance on complex development tasks.
• Collaborate with architects, engineering teams, data engineers, product teams, security teams, and other stakeholders.
