About the role
We’re looking for a Senior HR Business Partner to support our Engineering and Product teams. This is a role for someone who wants to be close to the business. You’ll work directly with leaders and managers on the people decisions that matter most as their teams grow: developing exceptional talent, building stronger managers, designing organizations, raising the performance bar and solving difficult people problems quickly.
What they're looking for
- 8+ years of strong HRBP experience: You have substantial experience partnering with Engineering, Product or similarly technical organizations and can build credibility with senior technical leaders
- Startup experience: You’ve worked in a fast-growing startup and understand the pace, ambiguity and changing needs that come with it
- 0→1 builder: You have personally built and launched development, talent or manager programs where little or no infrastructure existed before
- Excellent judgment: You can work through complex people situations, identify what actually matters and make clear recommendations without relying on a playbook for every answer
- Manager coach: You can make managers better, including experienced leaders who expect their HR partner to challenge their thinking
- High performance orientation: You know how to differentiate performance, develop exceptional people and address performance issues directly
