Leading Microsoft is arguably the toughest (and most up-for-grabs) job in tech right now, but salvaging a catastrophic government website launch is a close runner-up. The White House has tapped Kurt DelBene, the outgoing Microsoft Office President, to head up a revamp of its notoriously glitch-ridden HealthCare.gov. US Secretary of Health and Human Services Kathleen Sebelius announced the appointment today, and Microsoft commented on the move via its official blog. DelBene, who spent 20 years at his former employer, stepped down as part of an internal reorganization early this year. He certainly won't have a gap in his resume; his final day at Microsoft was yesterday, December 16th.
