Why have you been on many juries?
Reforms expanded the pool, for instance in NY.
From a 1996 NY Times article:
"As of Jan. 1, all 27 former exemptions and disqualifications for jury duty in New York State have been repealed"
"...as many as one-third of Long Island's residents have been exempt from jury duty because of their white-collar professions, particularly doctors, dentists and lawyers"

Also, I’m fortunate to have a job where there is no financial penalty for service, I find it interesting, and I’m not comfortable hamming up some nonsense to avoid it. I’m always surprised I’m picked because of my job (lawyers don’t like engineers on juries), and I am friends or relatives with a bunch of attorneys and policemen.
Consider a legal trial to be a giant machine executing a huge set of detailed and arcane and sometimes arbitrary instructions. Either the machine does the right thing (one side arguing there was no crime) or the wrong thing (the other side arguing there was a crime). What engineer doesn't love figuring out why the machine's behaviour is correct or incorrect?
That's not universal -- two of the most religious people I've met were some flavor of engineer; they never bother to challenge their own biases -- but in aggregate they're a riskier jury pick than a teamster or housewife or cashier.
Trial lawyers present a narrative to the jury, and thus prefer jurors who are more likely to believe the presented narrative. Your typical engineer believes themselves to be capable of discerning truth independent of expert opinion. This could be an advantage or a disadvantage, depending on how the trial lawyer plans to present their narrative.
