• Translate architectural patterns into concrete platform implementations that enforce agreed boundaries, contracts, and standards.
• Evaluate technical trade-offs and recommend appropriate solutions.
• Identify and resolve cross-cutting technical debt, and flag scalability, reliability, security, and performance risks early.Hands-On Engineering & Quality
• Own and evolve critical platform components in production.
• Write clean, testable, maintainable, and production-ready code.
• Perform deep code reviews on platform-facing changes and establish engineering best practices.
• Troubleshoot complex production issues and perform root-cause analysis.
• Support CI/CD, automated testing, monitoring, logging, and overall operational readiness.

Required Experience

• 12–16 years of overall hands-on software engineering experience.
