What you should know
If you are interviewing for Mobile 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. Native iOS (Swift) and Android (Kotlin) developers earn 10 to 15% more than cross-platform specialists in React Native or Flutter. Experience shipping apps with millions of active users, complex offline sync, or real-time features commands the highest rates. Fintech and health tech apps pay the strongest premiums.
Junior mobile developers start at $75,000 to $95,000, progressing to mid-level at $105,000 to $145,000 within three years.

In St. Louis, 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. RSUs at major tech companies add $30,000 to $80,000 annually for senior mobile roles. Signing bonuses of $15,000 to $40,000 are common, and many employers offer device stipends plus annual Apple and Google developer account fees. And on the tax side: missouri's top income tax rate is about 4.8%, and St. Louis City adds a 1% earnings tax. The low base cost of living means your after tax salary still stretches further than in most metros. When someone quotes you $124,000, ask what the total package looks like. The gap between base and total comp is where real money hides.
