Fractional Director/Senior Director Human Resources

Quotient is seeking an experienced HR leader to serve as a fractional, part-time (3 days per week), on-site HR Consultant supporting our UK location. This is a consultant/independent contractor engagement, not a permanent employee position. The HR Consultant will report directly to the Consultant VP of HR (US-based) and will operate as an embedded member of the global HR function during the term of the engagement.

This consultant will serve as the senior HR business partner to UK leadership, translating enterprise-wide people strategies into effective local execution while maintaining close collaboration with US-based HR leadership. This consultant will be the key HR thought partner to on-site leadership (C-level as well as R&D leadership team) in working to drive optimal team structure, a performance mindset, and a team-based culture. The role requires disciplined alignment with enterprise HR governance, ensuring that all UK-based people practices, policies, and decisions are fully integrated with global standards and leadership oversight. This engagement does not establish a standalone or independent UK HR function; rather, the consultant will operate within an established global HR structure and decision-making framework. The successful candidate will balance strategic insight with hands-on implementation in a dynamic, early-stage environment, helping to scale the organization while maintaining consistency, compliance, and cultural cohesion across geographies.

Responsibilities:

• Serve as the senior HR business partner for the UK site under a consulting engagement, reporting to and operating under the direction of the Consultant VP of HR (US-based).
• Serve as key thought partner to CSO and CDO, as well as members of their R&D leadership team, in continually evaluating their teams’ structures, manager and leadership effectiveness, and supporting a high performance team-based culture.
• Execute and localize global HR strategies, policies, and programs in alignment with enterprise frameworks.
• Ensure UK HR practices remain fully integrated with the broader global HR function.
• Provide strategic input to UK leadership on organizational design, workforce planning, and talent strategy in coordination with global HR.
• Lead performance management processes in alignment with company-wide frameworks.
• Partner with the Consultant VP of HR on compensation planning, promotion processes, and talent reviews.
• Advise leaders on employee relations matters, ensuring fair, consistent, and compliant practices under UK employment law.
• Support talent acquisition strategy and hiring decisions in coordination with global recruiting processes.
• Coach UK-based managers to strengthen leadership capability and reinforce company values.
• Drive employee engagement and culture initiatives that reflect enterprise priorities.
• Establish scalable and compliant HR processes appropriate for a growing UK workforce.
• Contribute to global HR projects and initiatives as needed.

• Demonstrated ability to operate effectively within an established HR governance structure.
• Experience aligning local HR execution with global strategy.
• Strong employee relations and leadership coaching expertise.
• Ability to work independently while remaining highly collaborative and integrated.
• Excellent communication and stakeholder management skills.

Desirable:

• Experience within life sciences, biotech, or high-growth organizations.
• Experience working with US-based leadership teams.
• Chartered MCIPD qualification or equivalent experience.
• Experience supporting scientific or technical populations.
• Prior exposure to venture-backed or early-stage environments.

Values and Behaviors:

• Encourage respectful disagreement and cultivate open-minded, ego-free interactions to continuously push each other towards excellence.
• Seek out diverse perspectives; practice active listening and genuine curiosity to ensure all contributions are valued, regardless of source.
• Recognize the impact of your behavior, language and attitudes, and strive for balanced, meaningful exchanges that enhance mutual growth and understanding in all interactions.
