A 40-year-old engineer in South Dakota pays a median $725/month for a Silver plan before subsidies — 7th of 15 on cost. The cheapest plan in the state is $512 from Avera in Lincoln. On counties covered, South Dakota ranks 13 of 15 for this occupation.
Work that crosses county and state lines makes network geography the binding constraint. A cheap HMO that only contracts in one metro is worthless 200 miles away, so these pages rank states by network reach and flag the ones with no PPO on the exchange at all.
Occupational context: Sedentary strain; site-visit exposure depending on discipline.
Worth being clear about what this does and does not affect: a carrier in South Dakota cannot ask what you do for a living, cannot charge a engineer more than a librarian of the same age in the same ZIP, and cannot exclude anything you were already treated for. Occupation only tells you which plan structure to shop for.
Premium is set by rating area, so a engineer in one South Dakota county can pay materially more than one an hour away. Six counties from across the state, cheapest Silver plan for a 40-year-old:

South Dakota has PPO plans available. For a engineer covering distance, that single fact outweighs premium: 0 of 66 counties here are served by one carrier, so an HMO bought in one metro may leave you out of network for the rest of your route.

Read the comparison as context, not as a shopping list. Your county of residence determines what you can buy, and for a engineer that is fixed unless you relocate. Where it is actionable is a move already in progress — that is a qualifying life event, and you have 60 days on either side of it.
Expense categories that typically apply to this trade: PE licensing, software, professional dues, site travel. Premiums are generally deductible above the line under IRC §162(l) when no employer plan is available to you or your spouse — a question for your CPA, not your agent.
If your household income is above the subsidy range, ACA is not automatically the answer. There are other categories of coverage that may fit, and they work very differently. That is a conversation, not a web page.
