Our Approach
This editorial hiring guide starts with sourced Greenville business context. Greenville City Economic Development Corporation materials show local activity in aerospace, automotive and advanced manufacturing, life sciences, and the knowledge economy. Those settings create separate physical-product, laboratory, and digital-service hiring requirements. 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 Greenville 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
An industrial brief should show how software, data, and infrastructure connect to plants, equipment, schedules, quality, and frontline users. 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
660
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 1.523 jobs per one thousand across the metro workforce.
Employment concentration
0.90 location quotient
Greenville-Anderson-Greer, SC sits near the national employment concentration for this proxy occupation. Use role evidence and work-model requirements to set the sourcing radius.
Annual wage reference
$61,110 to $138,280
The metro median is 24% below the national Data Scientists median. Do not use the gap to discount niche platform or domain experience. BLS reports a $91,490 median for the proxy occupation in Greenville-Anderson-Greer, SC.
Hiring brief scenarios
These scenarios connect location context to role responsibilities. Use them as prompts to verify with the employer, not as measures of Greenville demand, clients, or candidate supply.
Sourced aerospace, automotive, and advanced manufacturing context
A 2025 city economic-development report says the South Carolina Technology and Aviation Center supports continued growth in aerospace, automotive, and advanced manufacturing. 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. These operations can connect approved designs, parts, suppliers, equipment, production orders, inspections, serial records, maintenance, safety evidence, and release authority.
Evidence to request: Request an evaluation set, retrieval diagram, or redacted design note that shows how the candidate tested grounding and access boundaries. Trace the aircraft, vehicle, or component from approved configuration and material through production or maintenance, inspection, serial history, discrepancy, delivery, and authorized release.
Sourced life sciences context
Greenville's economic-development site describes Main Street Labs as a downtown laboratory hub for life-sciences companies. 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. Life-sciences platforms may join samples, experiments, instruments, protected clinical data, laboratory results, product records, validation, quality events, and regulated retention.
Evidence to request: Use a design exercise with a fixed quality target and cost limit. Score the tradeoffs, measurement plan, and fallback behavior. Set the scientific or product question, sample lineage, protected fields, instrument interface, reproducibility or validation test, quality decision, retention rule, and approval owner.
Sourced knowledge economy and industrial technology context
Greenville's economic-development materials connect the local knowledge economy to research, product development, technology, and manufacturing activity. 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. Knowledge-economy roles can span digital products, engineering research, client delivery, industrial software, analytics, intellectual property, production systems, and continuing support.
Evidence to request: Ask for an incident or regression account with the signal, diagnosis, change, and post-release check the candidate owned. Name the research, product, or client boundary, technical artifact, data and intellectual-property ownership, production interface, release evidence, delivery decision, and support obligation.
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 sensor or production data, edge constraints, model drift, operator review, and measurable process outcomes. The manufacturing and operational systems context is an editorial scenario, not a measured claim about Greenville.
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 sensor or production data, edge constraints, model drift, operator review, and measurable process outcomes. The manufacturing and operational systems context is an editorial scenario, not a measured claim about Greenville.
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 sensor or production data, edge constraints, model drift, operator review, and measurable process outcomes. The manufacturing and operational systems context is an editorial scenario, not a measured claim about Greenville.
