Design, test, and iterate on system prompts for production LLM applications
Build automated evaluation pipelines to test prompt quality at scale
Manage prompt versioning, A/B testing, and regression detection across model updates
Build structured output extractors using JSON mode, function calling, Instructor
Optimize prompts for cost (token efficiency) and output quality simultaneously
Research and apply new prompting techniques (Chain-of-Thought, ReAct, metacognition)
Maintain prompt libraries and internal best practice documentation
Python: comfortable enough to write eval scripts and full API integrations
LLM API fluency: OpenAI, Claude, Gemini; deep understanding of parameters
Evaluation design: build test sets, define metrics, measure regressions over time
Prompt patterns: zero-shot, few-shot, CoT, Tree-of-Thought, ReAct, meta-prompting
Structured outputs: JSON mode, function calling, Instructor library, Pydantic validation
RAG basics: chunking strategies and their impact on retrieval and prompt quality
Technical writing: precise, unambiguous natural language instruction composition
Primary LLM integration
LLM evaluation and tracing
Structured output extraction
Prompt testing and regression detection
Scripting and experimentation
Experiment and metric tracking
Prompt documentation and versioning
Attention and context window mechanics (at conceptual level)
System prompt vs user prompt: how models treat each differently
Temperature and sampling parameters: deterministic vs creative output use cases
Hallucination causes: training data gaps, conflicting context, ambiguous instructions
Cost calculation: tokens, pricing tiers, context management strategies for production
Experiment daily with Claude, GPT-4, and Gemini on complex, multi-step tasks
Implement 10 prompt patterns with quantitative test cases measuring quality change
Python: write an eval script that automatically scores 100 LLM outputs on defined criteria
Build a public prompt engineering resource (blog, GitHub repo, or Twitter thread series)
Promptfoo: automated testing of prompt variants across 200+ test cases
Build a structured data extraction pipeline using function calling + Instructor library
Implement a few-shot prompt generator that dynamically selects examples via embeddings
RAG quality testing: measure how chunking strategies affect final response quality
G-Eval: implement GPT-as-judge for nuanced quality scoring at scale
Build a full prompt management system: versioning, A/B testing, rollback workflow
Contribute to open-source: Promptfoo, RAGAS, or publish a widely-read prompting guide

LLM evaluation standard
Very high remote potential. This role is entirely remote by nature. Companies hiring are predominantly US/EU AI startups.
High and growing. Companies outsource prompt optimization and evaluation setup. Retainer contracts for ongoing maintenance are common.
Treating this as a permanent standalone career without adding engineering or product skills
Not building evaluation infrastructure — prompting without measurement is guesswork
Falling behind on model releases — this field changes monthly; continuous learning is mandatory
Evolving into AI Engineer and AI Product roles. Pure prompt engineering as standalone will commoditize as models improve. Long-term value: combine with engineering depth, domain expertise, or evaluation infrastructure ownership.
Build AI-powered products using LLMs, RAG systems, and agentic workflows for production applications.
