Our Approach
This editorial hiring guide starts with sourced Seattle business context. Seattle's Office of Economic Development separates technology, commerce, life sciences, green industry, and maritime logistics in its current sector map. That structure supports several technical search paths with different system and support 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 Seattle 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 product-company brief should connect the role to users, release decisions, service measures, and ownership after launch. 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
8,370
BLS publishes a sizable metro employment estimate for the proxy occupation. The intake still needs to isolate the platform, delivery stage, and ownership required here. The estimate equals 4.011 jobs per one thousand across the metro workforce.
Employment concentration
2.38 location quotient
Seattle-Tacoma-Bellevue, WA 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
$81,130 to $230,980
The metro median is 37% above the national Data Scientists median. Test whether the role's scope and location requirement support that difference. BLS reports a $164,740 median for the proxy occupation in Seattle-Tacoma-Bellevue, WA.
Hiring brief scenarios
These scenarios connect location context to role responsibilities. Use them as prompts to verify with the employer, not as measures of Seattle demand, clients, or candidate supply.
Sourced software and emerging technology context
Seattle's Office of Economic Development lists technology as a key industry and names software, gaming, retail technology, and emerging technologies within that category. The page supports a software-sector scenario without measuring demand for a specific role. 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. Product teams may own high-volume services, internal platforms, experiments, and release processes shared across several engineering groups.
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 hire owns a customer product, developer platform, model service, or internal system and name the service level attached to it.
Sourced retail and ecommerce context
Seattle's key-industries page places retail and ecommerce within its technology profile. A technical role in that setting may support catalog, search, recommendations, customer identity, orders, payments, or fulfillment data. 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. Commerce services face peak traffic, data freshness requirements, partner dependencies, and direct links between technical failures and customer orders.
Evidence to request: Use a design exercise with a fixed quality target and cost limit. Score the tradeoffs, measurement plan, and fallback behavior. Record the scale, peak event, failure budget, and business metric the candidate was accountable for in prior commerce work.
Sourced maritime, manufacturing, and logistics context
Seattle lists maritime, manufacturing, and logistics as a key industry connected to global trade. The same city profile distinguishes this work from software and life sciences, which helps employers define asset, warehouse, route, or supplier-system experience. 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. Trade and asset systems may run across ports, warehouses, carriers, and maintenance teams with limited tolerance for lost or delayed records.
Evidence to request: Ask for an incident or regression account with the signal, diagnosis, change, and post-release check the candidate owned. Identify the physical operation, partner interfaces, operating schedule, and recovery process the role must support.
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 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 Seattle.
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 Seattle.
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 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 Seattle.
