Our Approach
This editorial hiring guide starts with sourced Louisville business context. Louisville Metro's economic-development plan identifies health care, manufacturing, transportation and warehousing, professional and technical services, finance, and insurance as key sectors. Hiring teams can use the employer's sector to define the systems and evidence a candidate must understand. An LLM Engineer brief should name the model boundary, retrieval sources, evaluation method, and production owner. API use alone does not show that a candidate can design grounded responses, control model behavior, or support an AI feature after launch.
Source LLM engineers who have shipped production retrieval, fine-tuning, inference, or evaluation systems
Assess candidates through architecture decisions, model tradeoffs, and evaluation methods
target a first candidate slate within 48 hours for qualified exclusive searches in our core disciplines after a completed intake
Permanent placements include a 90-day replacement guarantee, subject to the signed agreement.
Start the search
Include the business context, systems, delivery phase, work model, compensation, and interview timeline. A Crosscheck search lead will use that context to calibrate the role before sourcing begins.
Local Market Brief
Decide whether the hire owns retrieval, model adaptation, application code, evaluation, or the full service. Record latency, cost, privacy, and failure-response requirements before sourcing so recruiter review can distinguish prompt experimentation from production engineering. The three sourced Louisville contexts below turn that scope into intake and screening decisions. They do not measure current vacancies, candidate supply, or Crosscheck client activity.
Editorial market scenario
Tie each must-have requirement to a task, system, risk, or deadline. Remove industry preferences that do not change how the person will perform the job. This is planning guidance, not measured local demand.
Editorial industry scenario
A health-sector brief should name the protected data, validation, availability, and user-workflow requirements the person will handle. Confirm that this context applies to the employer before using it in the search.
Screening focus
We test for model or application ownership, evaluation discipline, data judgment, and evidence that the candidate has shipped reliable AI systems.
Published labor benchmark
BLS does not publish an occupation matching LLM Engineer. Crosscheck uses Data Scientists (15-2051) as the closest published broad benchmark; it is not a count or pay estimate for this exact specialty.
BLS OEWS May 2025, published May 15, 2026
Published metro employment
650
BLS publishes fewer than one thousand metro jobs for the proxy occupation. Treat the estimate as a reason to define location flexibility before outreach. The estimate equals 0.945 jobs per one thousand across the metro workforce.
Employment concentration
0.56 location quotient
Louisville/Jefferson County, KY-IN reports a below-national employment concentration for this proxy occupation. Decide which requirements justify a wider regional or remote search.
Annual wage reference
$64,100 to $164,110
The metro median is 17% below the national Data Scientists median. Do not use the gap to discount niche platform or domain experience. BLS reports a $99,980 median for the proxy occupation in Louisville/Jefferson County, KY-IN.
Hiring brief scenarios
These scenarios connect location context to role responsibilities. Use them as prompts to verify with the employer, not as measures of Louisville demand, clients, or candidate supply.
Sourced health care and social assistance context
Growing Louisville Together identifies health care and social assistance as a key Louisville sector and describes health care as the city's largest employer category. Connect the local operating context to the data that may enter prompts or retrieval. Require a candidate to explain document preparation, permissions, citation behavior, evaluation cases, and the team that approves changes. Health operations can join consumer, patient, provider, facility, referral, workforce, claims, and finance records with restricted fields and services that continue through ordinary release work.
Evidence to request: Request an evaluation set, retrieval diagram, or redacted design note that shows how the candidate tested grounding and access boundaries. Specify the care or administrative process, user populations, protected records, system boundaries, access reviews, service window, integration recovery, and acceptance owner.
Sourced manufacturing context
Manufacturing appears among Louisville's key sectors, and the city plan connects its advanced manufacturing position to water, utilities, and supply-chain capacity. Set the model-selection decision around the workload rather than a preferred vendor. Ask how the engineer compared hosted and open models, measured quality, handled unsafe output, and controlled latency or token cost. Plant work may connect products, equipment, materials, quality, shifts, maintenance, suppliers, costs, and customer commitments with limited time for production changes.
Evidence to request: Use a design exercise with a fixed quality target and cost limit. Score the tradeoffs, measurement plan, and fallback behavior. Define the sites, products, production model, utility or equipment dependencies, quality checks, source systems, outage limits, fallback, and operational sign-off.
Sourced logistics and business services context
Louisville's plan lists transportation and warehousing, professional and technical services, finance, and insurance among the city's key sectors and describes major rail, airport, interstate, and river connections. Treat launch support as part of the role. The brief should cover observability, feedback review, version changes, rollback, and ownership when retrieval or model behavior produces a poor result. Partner and freight processes may involve accounts, contracts, orders, warehouses, shipment events, service timers, currencies, financial postings, and data from carriers or customer systems.
Evidence to request: Ask for an incident or regression account with the signal, diagnosis, change, and post-release check the candidate owned. Map the partner and shipment lifecycle, transaction volumes, system authorities, transport interfaces, exception timing, reconciliation, support coverage, and period-end dependency.
Interview scorecard
Ask each candidate the same core questions. Score the evidence, ownership, and judgment in the answer instead of relying on job-title or keyword matches.
1. LLM Engineer: OpenAI GPT-4o / o1
Choose an OpenAI GPT-4o / o1 decision from your work as LLM Engineer. Which constraint changed the design, and what evidence supported the result?
Use the answer to assess data provenance, evaluation by use case, human review, privacy, and production monitoring. The healthcare and life-science systems context is an editorial scenario, not a measured claim about Louisville.
2. Prompt Engineer: Anthropic Claude
Describe project work you completed as Prompt Engineer involving Anthropic Claude that did not follow the original plan. What did you own, and how did you correct it?
Use the answer to assess forecast or routing evaluation, changing inputs, latency, exception handling, and business review. The logistics and distribution operations context is an editorial scenario, not a measured claim about Louisville.
3. RAG Architect: Llama 3 / Mistral / Gemma
For a Llama 3 / Mistral / Gemma system you supported, explain the handoff, operating limits, and measures used after launch. Where did your responsibility begin and end?
Use the answer to assess data provenance, evaluation by use case, human review, privacy, and production monitoring. The healthcare and life-science systems context is an editorial scenario, not a measured claim about Louisville.
