Senior Human Resources Generalist in London

We’re looking for a “superstar” Senior HR Generalist to join us in our London office. This is a high-impact, high-growth role designed for someone who is a master of HR fundamentals and is ready to stretch into high-level project ownership. This role is full of opportunity and will ebb and flow based on the needs of a rapidly scaling firm. One week you might run point on designing and implementing manager training programs; the next, you’ll lead the integration of new colleagues across the globe as we expand.

Whether it's managing employee relations, learning & development, or bridging cultural gaps across time zones, you are someone who is "up for anything". This is a career-defining role for a high-potential professional who wants to grow alongside the firm.

• Serve as one of the primary HR points of contact for employees in the GMT(+) time zones, ensuring our global team feels connected to Bitwise culture and supported across all HR programs.
• Play a key role in onboarding and integrating new colleagues from recent acquisitions. Act as a dedicated resource to bridge cultural gaps, harmonize policies, and ensure new team members feel fully connected and productive from day one.
• Lead firm-wide manager training initiatives. Design and deliver resources that empower managers to lead high-performing teams, focusing on feedback, coaching, and navigating the nuances of global team management.
• Support and facilitate the rollout of performance reviews, promotion cycles, and career development frameworks.
• Partner closely with the HR team on the full-cycle recruiting process, including drafting job descriptions, sourcing talent, and managing candidate pipelines through to the offer phase.
• Partner closely with the HR team on end-to-end onboarding and offboarding experience for all hires, ensuring every new colleague has a clear path to productivity and an exceptional first impression of the firm.
• Maintain and update employee handbooks and HR records, ensuring the firm remains compliant with local and international labor regulations.
• Act as a trusted resource for all individuals to ensure the firm is creating an environment that allows people to be themselves and do their best work.
• Partner with the Workplace Experience Manager to develop and run rituals that bridge the gap between our London, US, and international colleagues.

• 4 to 6 years of hands-on HR experience within a fast-moving, "build-mode" environment.
• Possession of the logic, reasoning, and high emotional intelligence (EQ) necessary to navigate ambiguity and solve almost any problem that arises.
• Proactive, nimble, and resourceful. This is a role for someone who doesn't wait for a manual but instead "moves fast with informed rationale" to get things done.
• Experience with, or a strong appetite for, international HR. Comfortable with flexing between an early morning or evening schedule to provide meaningful support to colleagues across the globe and eager to master global employment nuances.
• Exceptional written and verbal skills with the ability to simplify complex policies and build immediate trust with all people across the firm.
• Low ego, curious, and genuinely kind; a professional and approachable partner who treats every interaction with care.
• Proficiency with Rippling, Lattice, and G‑Suite is a major plus; an ability to quickly adopt and optimize new HR tech is essential.
• A "no task is too small" mindset. Whether it is a high-level acquisition integration or a tactical administrative project, every task is approached with the same level of professionalism and enthusiasm.

• Compensation: £90,000 - £110,000 + Equity
• Equity compensation as a component of all offers
• Health insurance
• Paid Parental Leave
• Company‑funded pension plan, no matching required
• Office spaces in London, San Francisco, and New York

• Paid company cell phone or stipend

• Ask "What would the client want?"
