As a Senior HR Specialist, you'll own and improve core people operations across the employee lifecycle. You'll be the go-to person for HR operations, policy and process execution, HRIS data integrity, and employee support — bringing structure and speed to a fast-growing startup environment. You'll partner closely with leadership and hiring managers to deliver a high-trust, high-quality employee experience at scale.

• Own end-to-end HR operations across onboarding, offboarding, employee changes, documentation, and record management.
• Be the HR operations lead, ensuring smooth execution, high accuracy, and strong employee experience across all touchpoints.
• Own HRIS administration (data quality, workflows, reporting, audits), and continuously improve how we use systems and tools.
• Draft, review, and manage contracts, letters, policy documentation, and HR communications, ensuring accuracy and consistency.
• Drive HR process improvement: identify gaps, redesign workflows, implement SOPs, and standardise scalable processes.
• Support and strengthen compliance practices (right-to-work, employment documentation, internal controls, data privacy, and local requirements as applicable).
• Payroll coordination/ownership (depending on structure): ensure inputs are accurate (attendance, leave, changes), liaise with payroll vendors/finance, and troubleshoot issues.
• Act as a first-line owner for employee relations and employee queries, resolving independently when possible and escalating complex matters appropriately.
• Lead key people cycles such as performance reviews, probation confirmations, annual processes, and related documentation/training for managers.
• Provide HR analytics and reporting (headcount, attrition, absences, compliance metrics), and turn insights into operational improvements.
• Partner with recruiting/ops teams to support hiring operations when needed (offers, pre-boarding, background checks, ATS/HRIS handoffs).

• 2-5 years of experience in HR/People Operations (startup or high-growth environment strongly preferred).
• Proven ability to own HR operations independently, manage multiple priorities, and deliver high-quality execution with minimal oversight.
• Strong knowledge of core HR processes (employee lifecycle, documentation, HRIS, payroll coordination, performance cycles, compliance basics).
• Excellent organisational skills and extreme attention to detail; able to build systems that scale.
• Strong written and verbal communication skills; confident working with employees and managers across all levels.
• Experience with HRIS/ATS tools, spreadsheets, reporting, and process documentation (SOPs, workflows, templates).
• High discretion and sound judgement when handling confidential and sensitive information.
• Comfortable in ambiguity; proactive mindset with a track record of improving processes rather than only running them.
• Bonus: experience supporting multi-country teams, visas/relocation coordination, or working with external payroll/HR vendors.

• Competitive salary
• Biannual bonus scheme
• Fully expensed tech to match your needs
• Paid annual leave
• Deliveroo breakfast and dinner allowance
