If you are evaluating a Humanoid Robotics Engineer offer in St. Louis, MO, here is the reality: $131,000 to $232,000, with $176,000 as the midpoint. 6% below the national average. Expertise in bipedal locomotion, whole body control, and human robot interaction drives top compensation. Do not accept the first number. These figures are Orbyt estimates, computed rather than measured, and must not be cited as Bureau of Labor Statistics figures; the published BLS wage for the occupation this role maps to is shown separately on this page.

Why this differs from the estimate above. The Orbyt estimate of $176,000 is 75% higher than this published figure. That is usually not an error in either number: BLS reports by occupation code, and Mechanical Engineers covers a different population than the Humanoid Robotics Engineer title as it is typically advertised. Both are shown, unreconciled, so you can judge which one describes the job you mean.
BLS publishes wages by occupation code, not by job title, so this figure covers every role mapped to Mechanical Engineers (SOC 17-2141) rather than Humanoid Robotics Engineer specifically. The St. Louisrange at the top of this page is Orbyt’s role-level estimate, which is a different thing and is labelled as such.

What you should know.
The Humanoid Robotics Engineer landscape in St. Louis is not what most salary sites will tell you. 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. Expertise in bipedal locomotion, whole body control, and human robot interaction drives top compensation. Engineers who can integrate perception, planning, and manipulation into coherent humanoid behavior are extremely rare. Experience with reinforcement learning for locomotion, sim to real transfer, and compliant control for safe human proximity adds significant premiums.
Junior humanoid robotics engineers start at $115,000 to $145,000. Mid level engineers with physical robot deployment experience earn $168,000 to $210,000. Senior engineers reach $215,000 to $270,000. Technical leads at leading humanoid robotics companies can exceed $360,000 in total compensation. 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. Equity at humanoid robotics startups adds 25 to 50% of total compensation given venture capital valuations. Performance bonuses of 15 to 25% are standard. Signing bonuses of $30,000 to $75,000 are common. Benefits include hardware lab access, testing facility time, and conference travel. 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 $176,000, ask what the total package looks like. The gap between base and total comp is where real money hides.
On negotiation: Emphasize your willingness to work in person at Cortex or the BJC campus. St. Louis employers offer higher packages for candidates who commit to the local innovation hubs. The range for Humanoid Robotics Engineers in St. Louis runs from $131,000 to $232,000. That is not a narrow window. Where you land inside it depends almost entirely on whether you negotiate and how well you prepare.
