High Volume (TOFU) Recruiter at HumanSignal

<div class="content-intro"><h2><strong>About HumanSignal</strong></h2> <p>Real-world data is the competitive edge in AI.</p> <p>HumanSignal is a human data partner for companies building AI models and products. Our customers ship better AI, faster, because we partner with their researchers from real-world data creation to annotation to delivery.</p> <p><br>We design and create datasets from scratch, recruit and manage the domain experts who evaluate model output, and run everything through our own platform, Label Studio, the open-source standard for data labeling and evaluation, used by over 1 million practitioners worldwide.</p> <p><br>We specialize in the operationally complex: real-world data collection, multimodal pipelines, and multi-step workflows. Advanced ML and AI teams use our enterprise platform to run their own data factories, and our services team to extend their reach where in-house capacity runs out.</p> <p><br>If you want to do work that materially shapes how the next generation of AI products gets built, we'd love to talk.</p></div><p><strong>Level:</strong> Individual Contributor&nbsp;<br><strong>Compensation:</strong> $55,000 – $100,000<br><strong>Location:<span class="Apple-converted-space">&nbsp;</span></strong>San Francisco, CA preferred; open to other remote options</p> <h2 class="text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold">About the Role</h2> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">HumanSignal Services runs on expert talent — and we need a lot of it, fast. As our high-volume recruiter, you are the engine that keeps our data programs fully staffed with the right contributors at the right time. This isn't a post-and-pray recruiting role. You'll be proactive, scrappy, and relentless — sourcing, screening, and moving candidates through a pipeline that never stops. When a program needs 500 vetted domain experts in 72 hours, you're the one who makes it happen. Speed matters here, but so does quality — the wrong contributor wastes everyone's time and hurts the data. You'll own both.</p> <hr class="border-border-200 border-t-0.5 my-3 mx-1.5"> <h2 class="text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold">What You'll Do</h2> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">You'll run high-volume sourcing across multiple channels simultaneously — job boards, LinkedIn, niche communities, referral networks, and anywhere else qualified talent lives. You'll screen candidates quickly and accurately, matching domain expertise to program requirements. You'll own pipeline health metrics — application volume, time-to-fill, screen-to-hire ratios — and hold yourself accountable to them daily. You'll work hand-in-hand with Strategic Project Leads and Operations to understand what each program actually needs, not just what the job description says. When a pipeline dries up or a new program spins up overnight, you don't wait to be told — you move. The programs don't stop for recruiting, so recruiting can't stop either.</p> <ul class="[li_&amp;]:mb-0 [li_&amp;]:mt-1 [li_&amp;]:gap-1 [&amp;:not(:last-child)_ul]:pb-1 [&amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3"> <li class="font-claude-response-body whitespace-normal break-words pl-2">Source and screen high volumes of candidates across multiple active programs simultaneously, maintaining quality and speed without sacrificing either</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Own top-of-funnel pipeline health: track application volume, conversion rates, time-to-fill, and screen-to-hire ratios daily</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Partner closely with Strategic Project Leads and Operations to understand program-specific requirements — domain expertise, availability windows, technical qualifications, and quality standards</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Build and maintain sourcing pipelines across job boards, LinkedIn, academic networks, professional communities, and referral programs</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Develop and iterate on outreach messaging, job descriptions, and screening criteria to improve conversion at every stage of the funnel</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Coordinate scheduling and logistics for screening calls, assessments, and onboarding hand-offs</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Flag pipeline risks early — if a program is at risk of understaffing, surface it before it becomes a delivery problem</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Continuously improve sourcing strategies based on data; identify which channels produce the best contributors for each domain</li> </ul> <hr class="border-border-200 border-t-0.5 my-3 mx-1.5"> <h2 class="text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold">Required Qualifications</h2> <ul class="[li_&amp;]:mb-0 [li_&amp;]:mt-1 [li_&amp;]:gap-1 [&amp;:not(:last-child)_ul]:pb-1 [&amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3"> <li class="font-claude-response-body whitespace-normal break-words pl-2">2+ years of high-volume recruiting or sourcing experience</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Proven track record managing large candidate pipelines under tight timelines</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Strong organizational skills; comfortable juggling multiple open requisitions at once</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Data-driven: comfortable tracking and reporting on funnel metrics</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Excellent written communication for high-volume outreach and candidate engagement</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Scrappy, self-directed, and comfortable operating with minimal process in a fast-moving environment</li> </ul> <h2 class="text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold">Preferred Qualifications</h2> <ul class="[li_&amp;]:mb-0 [li_&amp;]:mt-1 [li_&amp;]:gap-1 [&amp;:not(:last-child)_ul]:pb-1 [&amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3"> <li class="font-claude-response-body whitespace-normal break-words pl-2">Experience recruiting for technical, domain-expert, or gig/contractor workforces</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Familiarity with AI data operations, annotation, or RLHF workforce programs</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Experience with ATS platforms (Greenhouse, Ashby, Lever, or similar)</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Background in marketplace operations, staffing, or workforce platforms</li> </ul> <hr class="border-border-200 border-t-0.5 my-3 mx-1.5"> <h2 class="text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold">About HumanSignal</h2> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">HumanSignal Services specializes in operationally complex, multimodal data collection and annotation — delivering the datasets that frontier AI research requires and remote workforce marketplaces can't.
