probably just something like this:

[total year range] Name of Company

-> indent [year range of last position] position title

   duties, interesting projects

-> indent [year range of 2nd to last] position title

   duties, interesting projects

Maybe include months for the individual roles depending on how short the year ranges are

I'd recommend prioritizing impact over "duties, interesting projects", especially quantatative impact e.g. "built widget that increased x by y%"

I'd also always include months

Once you get fairly far into your career, covering each title separately adds up to a lot of uninteresting text. My two (now 3) long-term jobs, my titles varied but my fundamental role didn't--though my responsibilities increased. (And often didn't go by my official title anyway.)

I just looked at my (out-dated) resume and, for my first two long-term jobs, I just put the years, one of two specific titles, and a list of major accomplishments.

That said, I've never had to go through an HR screen so my resume probably never mattered much.
