Hire Prompt Engineers

Dedicated prompt engineering talent

Hire prompt engineers and prompt engineering experts from Relevance Lab — for prompt and context design, evaluation harnesses, guardrails and jailbreak testing, and token and cost optimisation.

Time to start

Quick answerPrompt engineers from Relevance Lab design and test the prompts, context assembly and output schemas that make an LLM feature reliable — building evaluation sets, tuning for accuracy and format, hardening against jailbreaks and prompt injection, and cutting token cost and latency without losing quality. They pair with your developers on the prompt, retrieval and evaluation layer.

Scope

What prompt engineers you hire do

Prompt & context design

System prompts, few-shot examples, context assembly and structured-output schemas.

Evaluation harnesses

Curated, versioned test sets with automatic and LLM-as-judge scoring, and regression runs.

Guardrails & red-teaming

Prompt-injection and jailbreak testing, refusal behaviour, and content-policy enforcement.

Cost & latency

Trimming context, summarising history, right-sizing retrieved context — token count drives cost.

Why Relevance Lab

Prompt talent that measures its work

Evaluation-first

They build a harness before they tune — improvements are measured, not asserted.

Security-minded

Injection and jailbreak defence is part of the job, not an afterthought.

Pair with your devs

Embedded in your team on the prompt, retrieval and evaluation layer.

Platforms behind them

RLCatalyst and Spectra, plus a bench for spikes.

Vetted for depth

Real prompt and evaluation engineering, not casual prompting.

You own it

Prompts, evaluations and configuration, in your repositories.

FAQ

Hire Prompt Engineers: frequently asked questions

Designs and tests the prompts, context assembly and output schemas that make an LLM feature reliable — building evaluation sets, tuning for accuracy and format, hardening against jailbreaks and prompt injection, and cutting token cost and latency without losing quality.

Yes — stronger models raise the ceiling but production reliability still depends on disciplined prompt and context design, evaluation, and guardrails, especially for regulated or high-volume use cases.

Often the fastest win — they add a proper evaluation harness, find failure modes, and improve accuracy and cost on the existing model before any deeper change.

Yes — embedded in your team and process, pairing with engineers on the prompt, retrieval and evaluation layer.

Typically within 1–2 weeks.
