Illinois

Feeny is tracking about 1,897 open tech roles in Illinois, from roughly 373 companies hiring across the state. Each comes from a company's own careers page, so a listing is a role being actively filled rather than a recycled aggregator entry. Chicago accounts for nearly all of it. Use the filters to narrow by role or seniority.

Chicago is where essentially all the openings are. The city's tech market mirrors its old commercial strengths: trading, logistics, and enterprise software. Manteno adds a small footprint outside the metro. Across the 2 Illinois cities we index, Chicago carries the weight almost entirely.

Chicago's quant trading firms hire heavily on the engineering side, with DRW, Jump Trading, and IMC pulling in low-latency and systems talent. On the software front, Stripe, Braze, and Harvey have planted downtown flags. Supply-chain startups like project44 lean into the city's logistics roots. Feeny lists roles from about 373 companies statewide, so the current set is worth scanning.

The range is wider than most people expect, running from high-frequency trading to logistics. The quant shops need C++ and low-latency engineers doing some of the most demanding work in the industry, while project44 and its peers hire for supply-chain software. Enterprise and product engineering fills the middle, with Stripe and Braze downtown. That HFT-to-logistics spread gives Chicago real breadth.

Chicago gives you a genuine big-city tech market without a coastal price tag. Cost of living runs about 6 percent below the national average, and housing stays moderate for a city this size, which is unusual. The scene is anchored by serious money in trading and a deep enterprise base, so the work skews technical and well-paid rather than trend-chasing. The honest trade is the winters, which are long and not for everyone.
