• You will work across different CS systems initiatives, applying your expertise to solve domain‑wide challenges and ensuring consistent architectural principles across our portfolio.

• You’ll mentor and collaborate with your peer Engineers and broader CS systems team, sharing architectural insights and fostering knowledge exchange across the organization.

• You are an excellent communicator in the English language.
