AI Engineer

AI Engineer

Hire AI engineers through Recruiting from Scratch. We place AI engineers at VC-backed startups building LLM-powered products and AI-native features. 29-day average time to hire.

What is an AI Engineer?

An AI Engineer builds AI-powered products and features — integrating large language models (LLMs), designing AI pipelines, building RAG systems, and creating the infrastructure that makes AI work reliably in production. Unlike a machine learning engineer who trains models, an AI engineer primarily works with pre-trained models (OpenAI, Anthropic, open-source LLMs) and builds the product layer on top: prompt engineering, retrieval systems, agent architectures, and evaluation frameworks. In 2026, the AI engineer is one of the most in-demand roles in tech.

At what stage should you hire an AI Engineer?

Immediately at AI-native companies. For companies adding AI capabilities to existing products, the right time is Series A or whenever AI becomes a core product bet — not an experiment. The signal: you have a clear use case where AI creates real user value, and the bottleneck is engineering capacity to build and ship it.

Common titles for this role

  • AI Engineer
  • LLM Engineer
  • Generative AI Engineer
  • Applied AI Engineer
  • AI/ML Engineer
  • AI Software Engineer

Typical background

Strong AI engineers combine solid software engineering fundamentals with deep LLM product experience. Recruiting from Scratch has placed AI engineers at Windsurf (AI coding), Mercor (AI recruiting), Decagon (AI customer support), and other top AI-native companies. We look for engineers who have shipped AI features to real users — with evaluation frameworks, prompt versioning, and production observability — not just weekend hackathon demos.

What does an AI Engineer do at a startup?

  • Design and implement LLM-powered features: chat interfaces, agents, document analysis, code generation
  • Build RAG (Retrieval Augmented Generation) systems with vector databases (Pinecone, Weaviate, pgvector)
  • Engineer and version prompts: system prompts, few-shot examples, chain-of-thought patterns
  • Implement AI evaluation frameworks: accuracy benchmarks, hallucination detection, regression tests
  • Optimize LLM inference: latency, token cost, caching strategies
  • Integrate AI model APIs: OpenAI, Anthropic Claude, open-source models via Ollama or Hugging Face
  • Build AI agent architectures: tool use, multi-step reasoning, memory systems

Key skills and qualifications

  • Strong software engineering fundamentals: Python, TypeScript, production-quality code
  • Deep LLM API experience: OpenAI, Anthropic, or comparable — not just surface-level API calls
  • RAG architecture: embedding generation, vector storage, retrieval strategies, reranking
  • Prompt engineering and evaluation: measurable quality benchmarks, regression prevention
  • AI infrastructure: inference optimization, streaming responses, context management
  • Understanding of AI failure modes: hallucination, context limits, prompt injection

Why hire your AI Engineer through Recruiting from Scratch?

  • We've placed AI engineers at Windsurf, Mercor, Decagon, and Scale AI — our network reaches the best AI talent in 2026
  • We distinguish between AI engineers who've shipped production AI and those who've only experimented — you only see the former
  • 29-day average time to hire — AI engineer searches are among the most competitive; our warm network is the advantage
  • Pre-vetted for production LLM experience including evaluation frameworks and observability
  • No upfront fees — contingency model

Frequently Asked Questions: AI Engineer

What does a AI Engineer earn?

Based on our database of 325 real postings, the median salary for an AI Engineer is $198K. Salaries typically range from $165K to $231K, reflecting variations in experience, location, and company size.

How long does it take to hire a AI Engineer?

Our average time-to-hire for an AI Engineer is 29 days, significantly faster than the industry average of 45-60 days. This efficiency comes from our extensive network of over 900K professionals and streamlined recruitment processes.

What should you look for when hiring a AI Engineer?

When hiring an AI Engineer, prioritize strong foundations in machine learning algorithms, data structures, and programming languages like Python. Look for candidates with practical experience in deploying AI models and a clear understanding of MLOps principles. We also recommend assessing their problem-solving abilities and curiosity for new technologies.

How do you assess a AI Engineer candidate effectively?

To effectively assess an AI Engineer, we recommend a multi-stage process including technical interviews focused on core AI concepts and coding challenges. Practical project assignments or case studies can reveal their ability to apply theoretical knowledge to real-world problems. Behavioral questions should explore their collaboration skills and approach to debugging complex systems.

Is AI Engineer typically a remote or in-person role?

The AI Engineer role has seen a significant shift towards remote work, especially for experienced professionals. However, some companies still prefer in-person or hybrid models for closer team collaboration or access to specialized hardware. We find that offering flexibility often attracts a wider pool of top talent.
