AI Knowledge Engineer.

Knowledge engineers build structured knowledge bases that ground LLM outputs in verified facts. This includes designing ontologies for RAG systems, building entity resolution pipelines, creating knowledge graph schemas, and developing fact-checking systems. The goal is to combine the fluency of LLMs with the accuracy of curated knowledge, reducing hallucinations and improving reliability.

Yes. The rise of RAG architectures and the hallucination problem in LLMs has renewed interest in structured knowledge representation. Organizations need engineers who can build reliable knowledge bases that AI systems can query. The field has evolved from traditional expert systems to hybrid approaches that combine knowledge graphs with neural retrieval, creating strong demand for updated skills.

In Des Moines, large enterprises typically pay AI Knowledge Engineers 10 to 20% more in base salary than small companies, but startups often compensate with equity that can exceed base salary value. Equity at enterprise AI companies adds $15,000 to $55,000 annually. The $94,000 to $157,000 range reflects this entire spectrum.

Many Des Moines employers are shifting toward skills based hiring for AI Knowledge Engineer positions. While a degree can accelerate your path to the median salary of $123,000, demonstrated experience, certifications, and a strong portfolio carry significant weight. Candidates without degrees may start closer to $94,000 but can reach the 75th percentile with three to five years of proven results.

Compensation reflects expertise in designing knowledge representation systems that enhance AI reasoning. Engineers who can build ontologies, knowledge graphs, and structured data pipelines that improve LLM accuracy earn premiums. Experience combining symbolic AI approaches with neural methods is a rare and valued skill. Domain expertise in specific knowledge domains adds 10% to 15%. In Des Moines, these factors can push compensation from the 25th percentile of $94,000 to the 75th percentile of $157,000 or beyond.

Ask about equity structure, vesting schedule, annual bonus targets, 401(k) match, health insurance premiums, PTO policy, and remote flexibility.
