The Role

We're looking for a Senior Sourcer to own research and pipeline building across the company. You'll be sourcing for everything — engineering, product, and design, but also finance, legal, BD, marketing, data science, you name it.

This is for someone who genuinely loves the hunt. You're great at digging through LinkedIn (and beyond), building sourcing strategies from scratch, and figuring out where the best people are hiding. You'll work closely with recruiters and hiring managers, but you'll have a lot of autonomy in how you find people and build pipelines.

What You’ll Do

• Lead sourcing for technical and non-technical roles across the company

• Do deep research to figure out where talent lives for current and future roles

• Build high-quality, targeted pipelines through proactive sourcing

• Put together curated candidates lists for recruiters to reach out to, or reach out yourself

• Partner with recruiters and hiring managers to understand what "great" looks like for each role

• Develop sourcing strategies — search strings, Boolean, talent mapping, the works

• Write personalized, high-signal outreach and manage early-stage candidate conversations

• Track sourcing activity, pipeline health, and conversion metrics to inform strategy and improvements

• Help build out our sourcing process and tools as we scale

What We’re Looking For

• 5+ years doing technical sourcing or talent research, ideally at a startup or high-growth company

• Experience sourcing across technical roles (engineering, product, design, data) and business functions (finance, legal, ops, etc.)

• Strong research skills — you know how to map markets, understand companies, and find people others miss

• You've built pipelines from scratch for hard-to-fill roles before

• Great writer — your outreach is thoughtful and personalized, not spammy

• Highly organized and comfortable running multiple searches at once

• Familiar with sourcing tools and ATS platforms (LinkedIn Recruiter, Greenhouse, Ashby, Gem, SeekOut, etc.)

• Proactive and strategic — you don't wait to be told what to do

Nice to Have

• You've sourced for crypto, fintech, or technical products before

• You've worked with senior stakeholders or on executive searches

• You're comfortable with data and reporting on sourcing metrics

• You like building repeatable processes that scale

Benefits

• Competitive salary & equity

• Unlimited PTO

• Full Health, Vision, & Dental coverage

• 401k match

• Hardware setup — new MacBook Pro, big display, & accessories
