We're looking for a Senior People Operations Partner / HRBP to lead the day-to-day people operations for Reaktor Japan.
Our Tokyo office is still a compact team. That means this role is hands-on by design. You will own the everyday mechanics of local HR, stay close to the team, and help leaders make careful people decisions when the situation calls for it.
You will also be one of the main links between Japan and Reaktor's global People/HR teams. This role involves more internal English communication than many of our client-facing roles in Japan. You will need to discuss people processes, compensation, performance, employment practices, and sensitive employee topics with colleagues outside Japan, and then make those discussions work in the Japanese legal and cultural context.
The interview process will include both English and Japanese conversations.
What you'll do
Run people operations for the Japan office
Manage the employee lifecycle from pre-onboarding to offboarding. This includes onboarding logistics, leave and attendance, performance cycle administration, employee data, routine HR questions, and employee documentation.
Handle local labor and compliance work
Keep Japan HR operations aligned with local labor law, company policies, and the rules of employment. Work with external partners on payroll, social insurance, annual health checks, expense-related processes, and other local HR administration.
Help people join and settle in
Support new joiners coming from Japan and from overseas. Make sure they understand the basics: how we work, which tools we use, what matters in our culture, and who they need to know during their first weeks.
Work with global People/HR colleagues on performance, compensation, organizational changes, and other people processes. Make global guidance clear, compliant, and workable for the Japan office.
Advise local leadership on people matters
Support local leaders on team health, engagement, retention, organizational changes, performance topics, and employee relations. Bring facts, context, and judgment. Some signals will come from data. Others will come from conversations.
Support recruiting from a People perspective
Work with Talent Acquisition and hiring teams when People/HR input is needed. This may include job descriptions, interview process clarity, candidate experience, or employer brand input.
Contribute to the office community
Work with office administration and team members on office practices, events, benefits, and wellbeing. Help keep our flat and transparent culture visible in the way people actually work together.
What you'll need
Around eight or more years of experience in HR Generalist, People Operations, HR Business Partner (HRBP), or a closely related role in Japan
Practical knowledge of Japanese labor law, labor administration, rules of employment, attendance, social insurance, and payroll coordination
Experience working with external partners such as payroll vendors, labor and social security attorneys, benefits partners, or other HR service providers
Experience across the employee lifecycle, including onboarding, performance cycles, employee relations, and offboarding
The judgment to handle confidential and sensitive employee matters with care
The ability to turn ambiguous people issues into clear facts, options, stakeholders, and next steps
Comfort working in a small, flat organization where you need to spot issues, set priorities, and move the work yourself
Native or near-native Japanese communication skills, especially for employment, policy, and employee-facing topics
Strong business English. You should be able to discuss HR operations, performance, compensation, organizational changes, and employee matters with global colleagues in English
Experience using HRIS, Google Workspace, Slack, or similar tools to keep people data and processes organized
Nice to have
Experience in a foreign-affiliated company, technology company, digital product company, creative agency, consultancy, or startup
Experience running People operations in a local office of around 30-50 people
Experience adapting global HR processes for a local market
Experience supporting recruiting processes, candidate experience, or employer brand from a People/HR perspective
Experience with compensation, performance, or organizational change projects
Experience working in a multinational or multicultural team
Experience supporting relocation, visa-related processes, or onboarding for non-Japanese employees
