Our Approach
This editorial hiring guide starts with sourced Durham business context. Durham's FY 2025 Strategic Plan Impact Report tracks workforce activity around life sciences and health care, information technology, and advanced manufacturing. The mix gives local hiring briefs concrete research, service, and production settings without implying that every employer is recruiting. 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 Durham 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
Ask candidates to show how they moved technical work into a maintained system. Record the handoff, monitoring, documentation, and operating constraints. 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
1,320
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 3.841 jobs per one thousand across the metro workforce.
Employment concentration
2.28 location quotient
Durham-Chapel Hill, NC reports more than twice the national employment concentration for this proxy occupation. Treat that as occupational context, not proof of available candidates.
Annual wage reference
$60,060 to $182,020
The metro median is 11% below the national Data Scientists median. Do not use the gap to discount niche platform or domain experience. BLS reports a $106,500 median for the proxy occupation in Durham-Chapel Hill, NC.
Hiring brief scenarios
These scenarios connect location context to role responsibilities. Use them as prompts to verify with the employer, not as measures of Durham demand, clients, or candidate supply.
Sourced life sciences and health care context
Durham's FY 2025 Strategic Plan Impact Report identifies life sciences and health care as high-demand industries used to align workforce programs and employer engagement. 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. Life-sciences and care platforms may join research samples, clinical records, laboratory instruments, trials, patient access, quality events, validation, and regulated retention.
Evidence to request: Request an evaluation set, retrieval diagram, or redacted design note that shows how the candidate tested grounding and access boundaries. Define the research or care workflow, sample or patient identity, protected fields, instrument or clinical interface, validation evidence, quality gate, retention rule, and approval owner.
Sourced information technology context
The Durham report also identifies information technology as a high-demand industry in the city's workforce and business-support work. 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. Information-technology roles can sit in product engineering, enterprise applications, data platforms, security, managed services, or public systems with different delivery evidence.
Evidence to request: Use a design exercise with a fixed quality target and cost limit. Score the tradeoffs, measurement plan, and fallback behavior. State the product or service boundary, users, data ownership, production authority, integration surface, reliability target, release evidence, and after-launch responsibility.
Sourced advanced manufacturing context
Advanced manufacturing is another high-demand industry named in Durham's FY 2025 impact report and related workforce alignment 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. Advanced production can connect designs, bills of material, suppliers, equipment, work orders, quality results, serial or lot records, inventory, maintenance, and cost.
Evidence to request: Ask for an incident or regression account with the signal, diagnosis, change, and post-release check the candidate owned. Trace the product from released design and sourced material through equipment, production, inspection, traceability, inventory, shipment, variance, and accountable process owner.
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 Durham.
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 experiment design, evaluation, reproducibility, deployment, monitoring, and product ownership. The research and technical commercialization context is an editorial scenario, not a measured claim about Durham.
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 Durham.
