Job summary

25madison is seeking a Platform Operations and Community Manager to own people operations across our NYC-based platform. You’ll manage HR, payroll, benefits, and PEO relationships while supporting incubations and portfolio ecosystem activities.

The role blends HR generalist duties with operations and community-building, requiring strong communication, project management, and the ability to work cross-functionally across the firm. This hybrid role is based in New York, NY.

Qualifications

• 4+ years in general operations, People ops, or related relationship/community-oriented role — startup, venture studio, or investment firm experience a plus.
• Strong working knowledge of PEO (i.e., Justworks) and other relevant HRIS platforms.
• Solid working knowledge of core HR operations and employment compliance (multi-state and multi-country a plus).
• Demonstrated ability to build processes and systems from scratch, not just execute existing ones.
• A builder's mindset: comfortable creating order out of a fast-moving, multi-entity environment and comfort with ambiguity and context-switching.
• Strong project management skills — you can juggle multiple workstreams across different entities without dropping balls.
• Excellent communication skills — you'll be translating between 25madison leadership, founders, and ecosystem stakeholders regularly.

• Own end-to-end HR operations for 25madison’s internal team, including onboarding, changes in status, exits, performance cycles, benefits, payroll, and PEO management.
• Maintain and update core HR policies and ensure compliance across jurisdictions.
• Serve as first point of contact for internal employee relations, escalating when needed.
• Support HR needs for newly launched incubations, including employment/contractor agreements and payroll setup.
• Serve as go-to resource for portfolio teams on HR ops needs (onboarding/offboarding, benefits, payroll).
• Continuously improve HR processes for scale through documentation, automation, and self-serve resources.
