These are two separate published estimates, not a time series. The Bureau of Labor Statistics does not encourage the use of OEWS data for time-series analysis. Differences between releases reflect changes in occupational classification, survey methodology, and the three-year pooled sample as well as any change in pay, so the two figures should not be read as a rate of wage growth.
Why this differs from the estimate above. The Orbyt estimate of $209,000 is 74% higher than this published figure. That is usually not an error in either number: BLS reports by occupation code, and Data Scientists covers a different population than the Staff LLM 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 Data Scientists (SOC 15-2051) rather than Staff LLM Engineerspecifically. The national range at the top of this page is Orbyt’s role-level estimate, which is a different thing and is labelled as such.

The salary figures on this page are computed estimates, not observed wages. Each one is a national role baseline scaled by a Bureau of Economic Analysis Regional Price Parity cost-of-living multiplier (2025 index) and rounded to the nearest $1,000. No published wage percentile is consulted and no wage survey response enters the calculation, so an Orbyt estimate must not be cited as a Bureau of Labor Statistics figure or as measured pay. The published wage data Orbyt holds is Bureau of Labor Statistics Occupational Employment and Wage Statistics, and Department of Labor H-1B Labor Condition Application filings, which record a filed minimum visa base wage rather than market pay. Where BLS publishes a wage for the occupation a role maps to, it is shown on that role's page as a separate benchmark, labelled with its occupation code, metro area and the number of employed workers it covers. Last updated August 2026. This role maps to BLS occupation code 15-2051. Full methodology.
Orbyt estimates the average Staff LLM Engineer salary in the United States at $209,000 in 2026, within a range of $170,000 to $270,000. 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. San Jose is the highest of the 81 cities at $297,000, while Jersey City offers the best purchasing power after cost-of-living adjustments. Model complexity, data pipeline scale, and infrastructure cost optimization are the primary drivers.

What you should know.
Model complexity, data pipeline scale, and infrastructure cost optimization are the primary drivers. Staff LLM Engineers with experience across the full ML lifecycle, from research prototyping to production serving, earn more than those focused on a single phase. Domain expertise in high-stakes verticals like healthcare, finance, or autonomous systems adds measurable premiums.
Staff LLM Engineers earn $206,000 to $343,000. This is an advanced individual contributor track. Progression leads to distinguished engineer or fellow titles at $412,000 to $480,000, or transitions to engineering leadership at comparable compensation.
Equity at top-tier companies adds 30% to 60% above base salary. Annual bonuses of 15% to 25% are standard. Signing bonuses of $25,000 to $75,000 are common when changing roles. Refresher equity grants vest annually. Relocation packages and executive benefits like financial planning are typical.
