What Can LLM Engineers Build?

From custom model fine-tuning to production inference infrastructure, our engineers deliver deep LLM expertise that goes far beyond API integration.

Custom Model Fine-Tuning

Fine-tune open-source or commercial LLMs on your proprietary data using techniques like LoRA, QLoRA, and full fine-tuning to create domain-specific models that outperform general-purpose ones.

LoRAQLoRADomain Adaptation

LLM Evaluation Pipelines

Build comprehensive evaluation frameworks to measure model quality, detect hallucinations, assess safety, and benchmark performance across tasks — ensuring your LLMs meet production standards.

BenchmarkingHallucination DetectionSafety Evaluation

Multi-Model Orchestration

Design architectures that intelligently route requests across multiple LLMs — using the right model for each task based on cost, latency, quality, and capability requirements.

Model RoutingCost OptimizationFallback Strategies

Production LLM Infrastructure

Deploy and serve LLMs at scale with optimized inference using vLLM, TensorRT-LLM, or Triton. Handle GPU orchestration, batching, caching, and auto-scaling for production workloads.

Common Questions

LLM Engineer Hiring FAQ

How is an LLM Engineer different from a GPT Developer?

While GPT Developers focus primarily on OpenAI's ecosystem, LLM Engineers are model-agnostic specialists who work across the entire LLM landscape:

  • Multi-Provider: Expert in OpenAI, Anthropic, Google, Meta (Llama), Mistral, and other providers
  • Open-Source Models: Can deploy and fine-tune open-source models on your own infrastructure
  • Deeper Model Knowledge: Understand model architecture, training dynamics, and optimization at a fundamental level
  • Production Infrastructure: Build serving infrastructure with vLLM, TensorRT-LLM, and custom inference pipelines

LLM Engineers help you make strategic model decisions, not just integrate a single API.

How quickly can I hire an LLM Engineer?

With WorkGenius, you can receive matched LLM Engineer candidates within 48 hours. Our AI-powered matching combined with human expertise ensures you get engineers with proven experience in your specific model requirements — whether that's fine-tuning, evaluation, or production deployment. Most clients complete the hiring process within 1-2 weeks.

What LLM technologies do your engineers specialize in?

Our network includes 900+ pre-vetted LLM Engineers specializing in:

  • Commercial Models: GPT-4, Claude, Gemini, Command R+, Cohere
  • Open-Source Models: Llama 3, Mistral, Mixtral, Phi, Qwen, DeepSeek
  • Fine-Tuning: LoRA, QLoRA, RLHF, DPO, full fine-tuning
  • Serving: vLLM, TensorRT-LLM, Triton, Text Generation Inference (TGI)
  • Evaluation: LLM-as-judge, HELM, custom benchmarks, safety testing
  • Optimization: Quantization (GPTQ, AWQ, GGUF), distillation, pruning

What does it cost to hire an LLM Engineer?

Rates vary based on experience level, specialization, and location. Typical ranges:

  • Mid-Level LLM Engineer: $90-140/hour
  • Senior LLM Engineer: $140-200/hour
  • LLM Architect/Lead: $200-280/hour
  • Research-Track LLM Engineer: $220-300+/hour

LLM Engineers command premium rates due to the specialized nature of their skills. WorkGenius provides transparent pricing with no hidden fees.

Should I use open-source models or commercial APIs?

This depends on your specific needs. Our LLM Engineers can help you evaluate the trade-offs:

  • Commercial APIs (OpenAI, Anthropic): Faster to start, no infrastructure needed, best for general tasks and rapid prototyping
  • Open-Source Models (Llama, Mistral): Full data privacy, lower cost at scale, customizable through fine-tuning, no vendor lock-in
  • Hybrid Approach: Use commercial APIs for complex reasoning and open-source models for high-volume, specialized tasks

An LLM Engineer can run benchmarks on your specific use case and recommend the optimal strategy for cost, quality, and latency.

What if the LLM Engineer isn't the right fit?

We stand behind our matching quality with a replacement guarantee. If an engineer doesn't meet your expectations within the first two weeks, we'll provide a replacement at no additional cost. Our 98% client satisfaction rate reflects our commitment to finding engineers with the deep model expertise you need.
