About XDOF

At XDOF, we’re at an inflection point. Frontier labs are racing to build general-purpose robots, and high-quality training data is the bottleneck. We’re building the foundation behind the foundation models – the data collection systems, operational capability, exabyte-scale data warehouse, and software toolchain – to help our partners drive the field forward.

We're hiring a Technical Sourcer to build the pipeline of talent that will take XDOF through its next stage of growth. You'll own sourcing for our hardest-to-fill technical roles — robotics engineers, data infra engineers, and product engineers — in a competitive, fast-moving market. This is a high-ownership role on a lean team: you'll partner closely with founders and hiring managers, not just take requisitions and run searches.

What You'll Do

  • Build and run sourcing strategies for technical roles across robotics, infrastructure, and product engineering, including niche and hard-to-fill positions.

  • Proactively identify, engage, and build relationships with passive candidates through channels like LinkedIn Recruiter, GitHub, niche robotics/ML communities, top journals /conferences, and referrals.

  • Partner with hiring managers and founders to translate role requirements into precise sourcing criteria and compelling outreach.

  • Write and iterate on outreach messaging that stands out to senior, in-demand engineers who aren't actively job-hunting.

  • Manage and continuously improve the top-of-funnel pipeline: track sourcing metrics, experiment with new channels, and double down on what converts.

  • Maintain a strong, organized candidate pipeline and ensure a fast, high-quality candidate experience from first touch through handoff to the interview process.

  • Help build sourcing process, tooling, and market maps as the team and hiring needs scale.

What We're Looking For

  • 2+ years of technical sourcing or recruiting experience, ideally in a startup or high-growth environment; experience sourcing for robotics, ML, or data infrastructure roles is a strong plus.

  • A track record of successfully engaging and closing passive, senior technical candidates in competitive markets.

  • Genuine curiosity about the technical work itself — comfortable learning enough about robotics, ML, and infrastructure to speak credibly with engineers and identify strong-fit candidates.

  • Excellent written communication; you can craft outreach that gets a reply from someone who gets a dozen recruiter messages a week.

  • High ownership and self-direction — comfortable building process from scratch rather than working within an established playbook.

  • Strong organizational instincts for managing pipelines, data, and follow-up across multiple concurrent searches.

  • Bonus: experience sourcing in the Bay Area robotics/hardware ecosystem, or a network in that space.
