He previously held finance leadership roles at Advent Software, Vitria Technology, Nuance Communications and Oracle (ORCL).
In the same announcement, Splunk said two-decade technology industry veteran Sri Viswanath will serve on its board.
He is currently the chief technology officer at Atlassian and previously held positions at Groupon, VMware (VMW), Sun Microsystems, Siemens and Ning.
