This has already been answered correctly by [R. Daughtry][1]R. Daughtry, but as per the comments, a few clues were not fully understood. So this answer only serves to fill in those blanks for anyone who wants to know.
Line 5: half way to becoming a maestro
A maestro is a talented and distinguished conductor, and another word for half is semi, so we get semi-conductor, which is part of the name and also the primary industry.
Line 8: my ambition guided me, and those I supported, in giant leaps
The clue here is giant leaps, like the "...one giant leap for mankind" in Neil Armstrong's moon-landing speech. Fairchild's chips were used in the guidance computer for the Apollo missions, an ambitious project. Thus, they guided both the company and literally supported the astronauts' lives in making such leaps.
Line 9: when things got too noisy I went one way
Noise was an issue in logic circuits, but diodes (a one-way conductor) were used to manage this noise.
Line 10: is this fair
