Oscar is working with a leading AI solution for Semiconductor Manufacturing Process Optimization organization that is looking for an experienced Full Stack Engineer to join their team.
As the Full Stack Engineer , you will be responsible for helping define the technical foundation of the product. In this role, you will design and strengthen the core platform capabilities that transform the solution from a functioning prototype into a robust, enterprise-grade system.

- Design and maintain secure, distributed backend systems that support mission-critical enterprise workloads.
- Lead modernization, refactoring, and hardening efforts to elevate the platform from early-stage to Tier-1 enterprise readiness.
- Champion best-in-class security, compliance, auditability, reliability, and operational excellence.
- Define and document lifecycle best practices, including upgrade paths, backward compatibility, deployment automation, tenant onboarding, configuration management, and HA / DR strategies.
