About the job
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.
