Manicule is building AgentRel: the systems that help companies become discoverable, cited, and recommended by AI agents.

For the last twenty years, companies optimized for people searching Google. The next interface is an agent answering a question, comparing products, or deciding what to recommend. We want to understand how those decisions happen and build the infrastructure companies need to influence them honestly.

That means solving two hard problems.

1. First: how does an LLM decide which content to retrieve, trust, cite, and use when recommending a company?
2. Second: how do we use AI to produce excellent technical content without filling the internet with slop

Ideally, you write excellent TypeScript, but you also understand the fundamentals of GEO—or have spent enough time studying LLMs to form a view on how they surface sources and recommend brands. You care about writing quality and can tell the difference between a useful technical explanation and fluent filler.

This is not a role where you receive finished specs and close tickets. You’ll work directly with our customers to understand the problem, decide what to build, and own it through production.

What you’ll do

• Build the systems behind our documentation, technical content, and agent workflows.
• Investigate how LLMs retrieve information, select sources, form recommendations, and cite brands. Lots of fun research to be done here.
• Turn editorial judgment into agent workflows, evaluations, and quality checks.
• Design how agents receive, retain, and use context across long-running jobs.
