About The Position

Nucs AI is scaling from a founding team to a structured, high-performing organization—and the people infrastructure has to scale with it. This is a fractional role for an experienced HR leader who can build the foundations: hiring practices, onboarding, compliance, culture, and compensation frameworks.
This is a hands-on role for someone who has built HR functions at early-stage companies and knows how to balance structure with the flexibility a startup demands. You’ll work directly with leadership to ensure we attract, retain, and support exceptional talent as we grow.

Requirements

• 8+ years of HR experience, including building people functions at early-stage or high-growth startups
• Strong knowledge of employment law, compliance, and HR best practices across US jurisdictions
• Experience designing compensation, equity, and benefits programs for startups
• Proven ability to recruit technical and clinical talent in competitive markets
• Excellent interpersonal and advisory skills; trusted counsel to founders and leadership

Nice To Haves

• Experience in MedTech, healthcare, or AI/ML companies
• Familiarity with international contractor and employment arrangements
• SHRM-SCP, SPHR, or equivalent certification
• Experience supporting companies through fundraising-driven hiring surges

Responsibilities

• Design and implement core HR processes: onboarding, offboarding, performance management, and employee lifecycle management
• Establish compensation and benefits frameworks appropriate for an early-stage, globally distributed team
• Build and maintain HR policies and an employee handbook that reflect our values and comply with applicable regulations
• Partner with hiring managers to define roles, run structured interview processes, and close candidates
• Develop employer branding and recruiting strategies that attract top talent in MedTech and AI
• Implement retention strategies including engagement programs, growth frameworks, and feedback mechanisms
• Ensure compliance with employment laws across relevant jurisdictions (US, international contractors)
• Advise leadership on organizational design, team structure, and workforce planning
• Champion a culture of transparency, accountability, and inclusion as the team grows

Benefits

• Mission with real impact – Your work directly improves how cancer patients are diagnosed and treated.
• Ground-floor opportunity – Early-stage company, meaningful equity, and outsized influence on the direction we take.
• World-class collaborators – Work alongside leading oncologists, nuclear medicine physicians, and AI researchers globally.
• Massive market tailwinds – Radioligand therapy and AI-driven oncology are multi-billion dollar growth markets.
• Autonomy and flexibility – Remote-first, flexible working. We hire great people and trust them to deliver.
• Equity upside – Competitive equity package. We’re building something big and want you to share in it.
