Functions of the Role

The People and Talent team is responsible for attracting, sourcing, retaining, and supporting world-class talent across Quantum Motion. Reporting to the Head of Talent and People, you will own the day-to-day lifecycle engine and operational delivery for our teams.

We are looking for an exceptional, process-driven People Operations Assistant to join us on an initial 6-month Fixed-Term Contract (with a view to extend).

By taking ownership of our day-to-day administrative engine - from onboarding and contract updates to global immigration tracking and payroll inputs - you will keep our employee experience running smoothly whilst we embark on the journey to transform our HR experience and systems.

We are in a scale-up building phase, meaning many of our backend processes are still manual, spreadsheet-heavy, and being designed in real time. We need someone who thrives on data accuracy, and takes pride in keeping everything clean, structured, and audit-ready.

The role encompasses:

• Onboarding & Lifecycle Excellence:
• Own the operational execution of the onboarding journey: drafting offer letters and employment contracts, coordinating background checks, setting up new joiners in Personio (HRIS System), and organising day-one logistics.
• Ensure every new starter experiences a warm, seamless, and high-touch welcome to Quantum Motion.
• Manage offboarding admin, ensuring leaver documentation and calculations (e.g., pro-rated holiday) are processed accurately.
• Immigration & Global Mobility:
• Act as the internal coordinator for our Right to Work compliance and UK Sponsor Licence records.
• Partner with our external legal advisors to track visa application statuses, document collections, and expiry timelines.
• Internal Mobility & Variations:
• Draft and issue contract variation letters for internal promotions, salary adjustments, and working pattern changes.
• Coordinate global mobility requests and internal transfers across our UK, US, Spanish, and Australian entities
• Payroll & Data Integrity:
• Act as the primary gatekeeper for monthly payroll inputs, collating data changes (new starters, leavers, bonuses, pension changes) with 100% accuracy.
• Systems & Process Automation:
• Maintain our HRIS (Personio) as a single source of truth
• Look for ways to transition our currently manual, spreadsheet-heavy processes into automated, self-service workflows
• Recruitment Support
• Partner with our Talent team to support recruitment operations during high-volume hiring phases
• Support candidate interview scheduling, when possible, across time zones and ensure a candidate-first experience

Experience - Essentials

• Proven experience in an HR or People Operations function (in-house) with a track record of executing high-volume administration within high-growth, technical, or scientific environments.
• Obsessive attention to detail and a great pride in data integrity - errors in payroll inputs, compliance checks, or contract variations bother you
• You are comfortable working in a fast-paced environment where processes are evolving.
• You don't mind manual administrative work and see it as an opportunity to build structure
• A continuous improvement mindset: you naturally spot inefficiencies, manual friction points, or data gaps and proactively propose cleaner ways to work while bringing others on the journey.
• An ability to navigate ambiguity and help build out structures
• Proactive, resourceful, and data-driven approach to HR administration

Experience - Desirable

• Hands‑on experience working in a scale‑up environment
• Practical understanding of UK sponsor licence management, visa processing, and Right to Work audits.
• Experience supporting rapid organisational scaling across international entities (e.g., UK, Spain, Australia, US).
• CIPD qualification (Level 3) or equivalent practical, hands‑on experience in a fast-paced scale‑up environment.

Benefits

• Be part of a creative, world-leading team
• Competitive salary and share options scheme
• Contributory pension scheme
• Group private medical insurance scheme
• Life Assurance
• Cycle-to-work Scheme
• Central London location
