BENGALURU: Another senior SAP executive has left the German company to work with former boss Vishal Sikka at Infosys, joining the procession of top talent finding its way to India’s second-largest software firm. Gordon Muehl , a 16-year veteran of SAP, who is the chief technology officer for security, is joining Infosys as its security czar, people aware of the matter said.The development underscores the growing need in the Indian IT industry to ensure safer internal systems and more robust software products as well as Sikka’s reliance on his former employer as he attempts to transform Infosys into a “nextgeneration services company.”“Muehl's expertise can be useful across different products in Infosys, especially (banking product) Finacle and (products unit) Edgeverve,” a person directly aware of the move said.“He has not yet joined, and as of now we are not looking at a chief security officer kind of a role--his expertise is tremendous from products point of view,” the person added. Infosys declined to comment.Since he joined the company in August last year as the company's first non-founder CEO, Sikka has hired some top talent from the world's biggest enterprise software maker. He has also moved quickly to position Infosys as a company that is being remodelled to for the challenges of the future by emphasising technical superiority.
