• Leadership Capabilities: A proven track record of mentoring and developing other engineers, with the ability to make pragmatic technical decisions balancing quality and delivery.
• Communication Fluency: Strong communication skills with the ability to explain complex technical concepts clearly to both technical and non-technical stakeholders.
