What you should know
If you are interviewing for Full Stack AI Developer roles in St. Louis, here is what you are walking into. St. Louis offers one of the most affordable major metro areas in the country, with a strong base in healthcare, financial services, and manufacturing. The region's anchor employers include Boeing, Centene, and Washington University's medical campus. A growing biotech and plant sciences corridor centered on the Cortex Innovation District is attracting new investment and talent. Pay depends on breadth of skills spanning frontend development, backend APIs, and ML model integration. Developers who can build complete AI-powered applications end-to-end without handoffs are highly valued. Expertise in LLM integration, vector databases, and real-time inference serving alongside strong web development skills drives 10 to 20% premiums.

The low base cost of living means your after tax salary still stretches further than in most metros. When someone quotes you $149,000, ask what the total package looks like.
