The Mint.com personal financial management service has largely been in cruise control since the Intuit purchase since 2009 for $170 million. Sure, there have been enhancements to Mint, the leading digital PFM, but they have been, what we would consider, around the edges: a budgeting enhancement here, a tweak of the view of account balances there.

That might be changing. It appears that Mint is stepping up to do more substantial development.

Five days ago Intuit posted a job ad for a “senior software web engineer” specifically for Mint. This is unique in and of itself, because Intuit tends not to hire for particular products.

Further, the senior software web engineer will be charged with “designing and developing new website enhancements that work across devices.” Considering Mint’s relatively thin enhancement history, that task deserves note. Last November, Mint did an update to its iOS app, adding a function it calls Trends. That was the first new function in Mint’s iOS app since June 2012.

A spokeswoman for Intuit declined to comment.

All this comes as rumors abound that Intuit is in talks to acquire Check, formerly known as PageOnce, for $350 million. Check has largely been the only venture actively pushing the PFM envelope with Mint in its development stupor.

Check has around 10 million users; Mint more than 14 million. Check was founded in 2007.
