If you are interviewing for Feature Store Engineer roles in Indianapolis, here is what you are walking into. Indianapolis has a diversified economy led by healthcare, life sciences, and motorsports engineering. Eli Lilly's headquarters drives a major pharmaceutical and biotech cluster. The city's extremely affordable cost of living means that even moderate salaries deliver strong purchasing power, making it an underrated destination for professionals seeking financial stability. Feature store engineers build infrastructure that serves ML features at scale, a specialized role that combines data engineering with ML platform knowledge. Experience with systems like Feast, Tecton, or custom feature platforms drives salary above standard data engineering roles. Companies running real-time ML inference at scale pay the highest premiums.

Junior feature store engineers earn $130,000 to $155,000. Engineers with 3 to 5 years of ML infrastructure experience reach $172,000 to $225,000. Senior engineers and tech leads earn $230,000 to $300,000, while staff engineers and ML platform architects can command $310,000 to $400,000. In Indianapolis, 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. ML platform companies offer equity packages of 20 to 40% of base salary. Annual bonuses typically range from 12 to 20%. Some firms provide additional compensation for on-call rotations supporting production feature serving systems at $10,000 to $20,000 annually. And on the tax side: indiana has a flat 3.05% state income tax, one of the lowest in the country. Marion County adds about 2.02% in local taxes. The combined rate remains well below most major metros. When someone quotes you $161,000, ask what the total package looks like. The gap between base and total comp is where real money hides.

On negotiation: Benchmark against pharmaceutical industry pay scales. Eli Lilly and the biotech cluster set high compensation floors that ripple across all professional roles in Indianapolis. The range for Feature Store Engineers in Indianapolis runs from $122,000 to $211,000. That is not a narrow window. Where you land inside it depends almost entirely on whether you negotiate and how well you prepare.
