What you should know
The AI Supply Chain Optimization Engineer landscape in Portland is not what most salary sites will tell you. Portland, Maine is a small but growing tech and creative economy hub. The city attracts remote workers and small companies seeking quality of life on the New England coast. Healthcare, marine industries, and a craft food and beverage sector round out the local economy. Compensation reflects the ability to apply ML to complex supply chain problems including demand forecasting, inventory optimization, and logistics network design. Engineers who can reduce supply chain costs by measurable percentages through AI-driven decisions earn premiums. Experience with operations research combined with ML provides the most valued skill combination.
Junior supply chain AI engineers start at $90,000 to $110,000. Mid-level engineers building production forecasting systems reach $130,000 to $158,000. Senior engineers designing network-wide optimization platforms earn $165,000 to $200,000. Directors of supply chain AI at major retailers or manufacturers can reach $220,000 to $280,000. In Portland, cost of living sits near the national average, so the numbers you see are roughly what you keep.
Base salary is not the full picture. Performance bonuses of 12% to 20% tied to cost reduction or service level improvements are common. Equity at supply chain tech companies adds $15,000 to $55,000 annually. Benefits at large retailers and manufacturers include comprehensive packages and product discounts. And on the tax side: maine's top income tax rate is 7.15%. Portland has no city income tax. The state rate is above average but offset by quality of life and access to rural New England. When someone quotes you $143,000, ask what the total package looks like. The gap between base and total comp is where real money hides.
On negotiation: Negotiate remote work flexibility. Portland employers know they compete with Boston and New York for talent and may offer location flexibility to attract top candidates. The range for AI Supply Chain Optimization Engineers in Portland runs from $107,000 to $181,000. That is not a narrow window. Where you land inside it depends almost entirely on whether you negotiate and how well you prepare.
