BLS publishes wages by occupation code, not by job title, so this figure covers every role mapped to Data Scientists (SOC 15-2051) rather than Reinforcement Learning Engineer specifically. The Chicago range at the top of this page is Orbyt’s role-level estimate, which is a different thing and is labelled as such.

Salary by role in Chicago.
What you should know.
Before you negotiate a Reinforcement Learning Engineer offer in Chicago, understand the terrain. Chicago's economy is anchored by finance, manufacturing, and a rapidly expanding tech sector. The city has become a major hub for fintech, enterprise SaaS, and e-commerce. With lower living costs than coastal cities and a deep talent pool from top universities, Chicago offers strong salary to cost of living ratios for professionals across industries. Compensation is driven by expertise in RL algorithm design, reward modeling, and simulation environment development. Engineers with production RLHF experience for language models command the highest salaries. Specialization in multi-agent RL, offline RL, or safety-constrained optimization adds 15 to 25% above standard ML engineering compensation.
Junior RL researchers start at $115,000 to $140,000. Mid-level RL engineers earn $150,000 to $200,000. Senior RL engineers reach $225,000 to $310,000, and principal RL engineers or research leads at top labs command $330,000 to $470,000 in total compensation. In Chicago, 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. Equity at frontier AI labs can equal or exceed base salary. Signing bonuses of $50,000 to $100,000 are common for experienced RL engineers. Annual bonuses of 15 to 20% are standard, with research publication bonuses at some organizations. And on the tax side: illinois has a flat 4.95% state income tax. Chicago does not levy a separate city income tax, making the overall burden moderate compared to coastal metros. When someone quotes you $121,000, ask what the total package looks like. The gap between base and total comp is where real money hides.
On negotiation: Reference the Bay Area or NYC salary band for your role, then negotiate a modest discount. Chicago employers routinely offer 85 to 90% of coastal pay. The range for Reinforcement Learning Engineers in Chicago runs from $83,000 to $173,000. That is not a narrow window. Where you land inside it depends almost entirely on whether you negotiate and how well you prepare.
