Own complex technical deliverables, identify architectural risks, and drive solutions to production issues.
Collaborate with architects, technical leads, and stakeholders to translate business requirements into scalable technical solutions.

Candidate Profile:

A highly experienced Java developer with strong architectural and problem-solving capabilities, able to independently own complex deliverables, influence technical decisions, and provide technical guidance to other developers.
