Our Approach
This editorial hiring guide starts with sourced Miami business context. Miami-Dade County materials identify international trade, aviation, financial services, information technology, and life sciences as separate economic-development targets. Hiring briefs need to distinguish border-spanning operations from regulated business systems and research work. 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.

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 Miami 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
List the production decisions the hire must own. Use those decisions to assess candidates whose prior title or industry differs from the opening. 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
3,040
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 1.079 jobs per one thousand across the metro workforce.
Employment concentration
0.64 location quotient
Miami-Fort Lauderdale-West Palm Beach, FL reports a below-national employment concentration for this proxy occupation. Decide which requirements justify a wider regional or remote search.
Annual wage reference
$62,590 to $199,130
The metro median is 6% above the national Data Scientists median. Test whether the role's scope and location requirement support that difference. BLS reports a $127,450 median for the proxy occupation in Miami-Fort Lauderdale-West Palm Beach, FL.
Hiring brief scenarios
These scenarios connect location context to role responsibilities. Use them as prompts to verify with the employer, not as measures of Miami demand, clients, or candidate supply.
Sourced international trade and logistics context
Miami-Dade County describes international trade as a central part of the local economy and ties that work to PortMiami, Miami International Airport, and the region's trade and logistics organizations. 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. Trade systems can cross carriers, ports, customs, warehouses, customers, currencies, and time zones while goods and financial records move on different schedules.
Evidence to request: Request an evaluation set, retrieval diagram, or redacted design note that shows how the candidate tested grounding and access boundaries. Trace one shipment or trade transaction through partner interfaces, status events, exceptions, financial postings, reconciliation, retention, and support ownership.
Sourced aviation and aerospace context
Miami-Dade lists aviation and aerospace among the industries sought through its Targeted Jobs Incentive Fund and identifies airport areas among its strategic locations. 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. Aviation work may join maintenance, assets, schedules, passengers, cargo, safety controls, secure access, vendors, and finance systems that must stay available during extended operating hours.
Evidence to request: Use a design exercise with a fixed quality target and cost limit. Score the tradeoffs, measurement plan, and fallback behavior. Identify the flight, cargo, maintenance, airport, or manufacturing boundary, then document uptime, access, audit, interface, and recovery requirements.
Sourced finance, technology, and life sciences context
The same Miami-Dade incentive program names financial and professional services, information technology, and life sciences among the industries the county seeks to support. 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 sectors can require transaction controls, protected records, validated calculations, model oversight, research traceability, or access reviews, depending on the system and business process.
Evidence to request: Ask for an incident or regression account with the signal, diagnosis, change, and post-release check the candidate owned. Name the sector, record type, regulated boundary, system of record, control owner, change authority, and evidence required for acceptance.
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 Miami.
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 evaluation tied to user tasks, latency, cost, monitoring, fallback behavior, and product ownership. The product and software delivery context is an editorial scenario, not a measured claim about Miami.
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 Miami.
