You will:

• Set direction for a technical team, ensuring architectural excellence and long-term solution maintainability.
• Lead and mentor junior and senior engineers, raising the technical bar across projects.
• Stay hands-on with high quality code contributions to data processing, modeling and deployment pipelines while delegating effectively.
• Partner with clients to translate complex business challenges into clear technical roadmaps and deliver measurable business outcomes.
