• Drive knowledge sharing across the engineering organization through Communities of Practice and communicate technical decisions and trade-offs to both technical and non-technical stakeholders.

• Solid understanding of automated testing, CI/CD pipelines, and modern software delivery practices, with experience using or adopting AI-assisted development tools. 
• Proven ability to independently solve complex and ambiguous technical challenges, selecting and adapting the most appropriate solutions. 
• Experience mentoring and coaching engineers, with exposure to technical interviews, promotion reviews, or other engineering talent processes.
