Our Approach
This editorial hiring guide starts with sourced Columbus business context. Columbus economic-development materials describe a regional base that includes insurance, health care, education, research, technology, logistics, and manufacturing. A useful hiring brief should select the employer's real operating setting and name the records, controls, and support obligations attached to it. 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 Columbus 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 finance-facing brief should identify the transaction, reporting, audit, privacy, and availability requirements attached to the role. 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
1,480
BLS publishes a narrower metro employment estimate for the proxy occupation. Screen for adjacent experience that transfers without lowering the production bar. The estimate equals 1.339 jobs per one thousand across the metro workforce.
Employment concentration
0.79 location quotient
Columbus, OH reports a below-national employment concentration for this proxy occupation. Decide which requirements justify a wider regional or remote search.
Annual wage reference
$63,530 to $169,380
The metro median is 10% below the national Data Scientists median. Do not use the gap to discount niche platform or domain experience. BLS reports a $107,950 median for the proxy occupation in Columbus, OH.
Hiring brief scenarios
These scenarios connect location context to role responsibilities. Use them as prompts to verify with the employer, not as measures of Columbus demand, clients, or candidate supply.
Sourced insurance and finance context
The City of Columbus identifies insurance as a major employer category and describes finance and insurance as part of the city's economic base. 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. Insurance and financial work can join customer or member records, policies, accounts, transactions, calculations, approvals, reconciliations, access controls, and reporting deadlines.
Evidence to request: Request an evaluation set, retrieval diagram, or redacted design note that shows how the candidate tested grounding and access boundaries. Name the product and transaction lifecycle, systems of record, calculation owner, approval evidence, close or filing calendar, access model, and exception route.
Sourced health care and research context
Health care, education, government, and research also appear in Columbus's official description of its largest employers and economic anchors. 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. Institutional work may combine patient or participant data, grants, projects, suppliers, assets, laboratories, protected access, validation records, and several reporting calendars.
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 care, research, or administrative process, protected records, project or grant boundary, connected systems, validation steps, review roles, and retained evidence.
Sourced logistics and manufacturing context
Columbus site-selection materials describe interstate, rail, air, cargo, trucking, warehouse, logistics, and distribution connections across the region. 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. Distribution and manufacturing systems can connect facilities, products, equipment, inventory, transport, production, suppliers, shipment records, and finance feeds with tight operating cutoffs.
Evidence to request: Ask for an incident or regression account with the signal, diagnosis, change, and post-release check the candidate owned. Map the facility and product flow, volumes, transport partners, source systems, update timing, error recovery, support coverage, reconciliation, 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 model evaluation, sensitive-data handling, explainability, and controls around automated decisions. The finance and insurance systems context is an editorial scenario, not a measured claim about Columbus.
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 Columbus.
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 model evaluation, sensitive-data handling, explainability, and controls around automated decisions. The finance and insurance systems context is an editorial scenario, not a measured claim about Columbus.
