intro to the role
We run the company out of a git-based knowledge graph. Every customer meeting note. Every investor and vendor conversation. Our writing style, our voice, icp, our positioning. Product ideas, platform new features and roadmap decisions. Marketing campaigns, LinkedIn content, outreach sequences, conference pipeline.
Structured, linked, versioned, with an agent layer on top that reads, writes, syncs, and briefs and completes tasks. This is what we build for our customers: take everything a company knows about its products -- manuals, specs, forum threads, support history -- and make it queryable by an AI that never forgets and never sleeps. We do the exact same thing for ourselves.
The person we're looking for has a specific character flaw: they cannot do the same thing twice without immediately wanting to eliminate the second time it happens. Not from the laziness, but because repetition feels like a design failure.
They think like a hacker. Every system has a seam, and if you find it, you can usually make 10x the impact with a fraction of the effort. They don't ask permission to automate. They notice the pattern and close it.
But they have taste. Output that looks like AI slop -- bothers them. Be it an email, customer proposal, blog posts or event announcement. The aesthetic of the work matters a lot as we're entering the Brand Age.
Your job is to be the judgment layer on top of everything the agents can't decide -- and to keep extending the system so the list of things agents can't decide gets shorter.
what you'll juggle
(disclaimer: most of this work exists to eventually eliminate itself except the last two)
GTM and BD ops -- pipeline, outreach, follow-ups, proposals
executive assistance -- scheduling, travel, logistics, occasional personal tasks
content and marketing ops -- LinkedIn, campaigns, contractor coordination
video content -- capturing, coordinating, and helping shape what gets made
knowledge graph maintenance -- keeping the company ontology clean, current, and growing
agent development -- extending the system so fewer things need manual handling
skills required:
obsessively detail-oriented and caring
comfortable in a terminal -- git, basic unix commands, CLI tools + Claude Code
comfortable with APIs -- you don't need to be an engineer, but you need to know how systems talk to each other
fast learner -- productive in a new system within days
strong writer -- natural voice, clean formatting, can quickly catch AI slop, drafts that don't need editing
taste -- cares about quality and aesthetic of work
systems thinker -- sees a recurring task as a design flaw, not a to-do item
