Our Approach
This editorial hiring guide starts with sourced Madison business context. Madison's CONNECT MADISON strategy identifies food systems, information technology with health IT and gaming, biotechnology, and precision manufacturing as target sectors. That local mix gives technical searches distinct product, research, and production constraints. 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 Madison 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 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
1,290
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 3.163 jobs per one thousand across the metro workforce.
Employment concentration
1.87 location quotient
Madison, WI reports an above-national employment concentration for this proxy occupation. Confirm current availability through the active search.
Annual wage reference
Not published
BLS did not publish an annual median for this proxy occupation in Madison, WI. Set compensation from the role scope and a current salary source rather than filling the gap with an estimate.
Hiring brief scenarios
These scenarios connect location context to role responsibilities. Use them as prompts to verify with the employer, not as measures of Madison demand, clients, or candidate supply.
Sourced information technology, health it, and gaming context
The City of Madison's economic-development strategy identifies information technology as a target sector, with a specific focus on health IT and gaming. 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 and game products can require very different evidence across protected records, identity, clinical workflows, real-time services, content, telemetry, release cadence, and user safety.
Evidence to request: Request an evaluation set, retrieval diagram, or redacted design note that shows how the candidate tested grounding and access boundaries. State whether the work supports care, administration, a game, or a shared platform, then name the data, user interaction, latency, access model, release cycle, safety check, and support owner.
Sourced biotechnology context
Madison's CONNECT MADISON strategy identifies biotechnology as one of the city's four target economic sectors. 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. Biotechnology work can cross experiments, samples, instruments, laboratory systems, genomic or clinical data, reproducibility, validation, regulated products, and manufacturing transfer.
Evidence to request: Use a design exercise with a fixed quality target and cost limit. Score the tradeoffs, measurement plan, and fallback behavior. Name the scientific or product question, sample and data lineage, instrument interface, reproducibility test, protected boundary, validation record, transfer step, and approving scientist or quality owner.
Sourced food systems and precision manufacturing context
The Madison strategy also targets food systems and precision manufacturing, with precision-manufacturing attention to custom fabrication and bicycle-related equipment. 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. These settings may join recipes or engineering definitions, source materials, production orders, equipment, lots or serials, quality checks, inventory, suppliers, and delivery.
Evidence to request: Ask for an incident or regression account with the signal, diagnosis, change, and post-release check the candidate owned. Trace the food or fabricated product from specification and source material through production, inspection, traceability, inventory, shipment, exception, and cost, with each control 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 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 Madison.
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 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 Madison.
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 Madison.
