I find the experts AI companies can't reach: PhDs, domain specialists and rare-language speakers for training and evaluation work, sourced and vetted worldwide, at volume and on deadline. I'm Oto Attang. At Invisible Technologies I went from sourcer to leading a 30-person talent operation.
At Invisible, I recruited experts for programs serving Microsoft, AWS, OpenAI, NVIDIA, Google, Meta, Cohere, ElevenLabs and AI21 Labs.
AI trainers, PhDs, domain experts and rare-language speakers for model-training programs, plus AI/ML, forward-deployed and research-adjacent hires across the US, UK and EU.
Sourcing, screening, onboarding and pipeline operations, month-to-month and scoped to your volume.
From $120 an hour, or a monthly retainer
Fixed-scope work with a deliverable you keep: pipeline rescues, rate architecture, assessment-integrity audits and recruitment media plans.
From $6,000, over two to three weeks
An industry-level view of AI expert supply for investors and strategy teams: how pay varies by field and country, where supply runs out, how vendors compete, and how AI-assisted cheating gets past screening.
Direct or through expert networks. Nothing confidential from current or former employers or clients.
$300 an hour, direct

“We already have a recruiting team.”
Good. Keep them. In-house recruiters are built for a steady flow of open roles. AI programs don't arrive that way. They arrive as 200 PhDs in six weeks, a language nobody on the team speaks, or a domain your usual channels have never reached.
Those people aren't applying. They're working, often in countries your team doesn't recruit in, and they respond to someone who knows how to reach them and how to vet them. That's a reach and bandwidth problem, and it's the part I take on.
Rare languages, PhD cohorts and niche domains. Your team stays on the roles it already fills well.
Program launches and deadline spikes, month-to-month, without headcount you won't need next quarter.
Search strings, outreach sequences, screening that holds up against AI-assisted cheating, and rate benchmarks for your roles. Your team keeps all of it.
Pipeline rescue at Invisible
A stalled PhD pipeline turned around within the month: 216 experts engaged and 69 replies, a 32% response rate.
Program delivery at Invisible
Zero attrition through delivery, as one of 144 concurrent requisitions run at an 86% fill rate.
Assessment integrity at Invisible
I initiated the standard that counters AI-assisted cheating in expert assessments, replacing the automated test, and directed its build with my assessment team.
Solon & Co., through partner networks
Senior engineering searches for technology companies in Europe, run through Refery and TechTree, with search strings, scored longlists, outreach and screening built for each role.
I joined Invisible Technologies as a sourcer on its expert marketplace, Meridial, and finished leading a 30-person talent operation. I onboarded 9,000+ experts in my first year and 15,000+ in my second, and the team I went on to lead grew the marketplace past 100,000 experts across 120+ countries and 94 languages.
In 2024, before my promotion to lead, I owned 144 concurrent requisitions that put 4,500+ of the experts I onboarded onto client programs, at an 86% fill rate. I also wrote compensation policy across 70+ countries and modeled a six-figure talent-acquisition plan with a cost per approved expert.
