• Perform coding, debugging, testing, and troubleshooting across all phases of the software development lifecycle.
• Conduct requirements analysis and translate business needs into technical specifications and high-quality code.
• Develop utilities and migration tools to support data and system transitions from legacy environments.
• Lead solution design discussions and contribute to architectural decisions in partnership with architects and product teams.
• Analyze and optimize system performance, scalability, reliability, and availability while ensuring adherence to engineering and security standards.
• Document system designs, integrations, workflows, and operational procedures (runbooks).
• Identify, diagnose, and resolve complex technical issues; recommend sustainable long-term solutions.
