* Improve CI/CD pipelines, automate testing, and enhance developer productivity

through modern engineering practices.

* Identify bottlenecks, debug complex production issues, and perform root-cause

analysis to drive long-term fixes.

* Design systems with a focus on scalability, resilience, observability,

monitoring, logging, and alerting.

* Contribute to cloud-native transformation initiatives, including

containerization, infrastructure as code, and auto-scaling architectures.

* Influence technical direction by challenging assumptions and proposing

innovative, pragmatic solutions.

* Take accountability for delivering high-impact outcomes aligned with team and

organizational goals.

QUALIFICATIONS

* Basic understanding of AI/ML concepts and Generative AI technologies,

similar technologies.

* A proactive and collaborative mindset with a strong desire to document

technical knowledge and improve team productivity.

Core Competencies

* Systems thinking and the ability to reason about edge cases, failure modes,

and operational behavior.
