Job description

About The Role and Team

Quantum Motion is a fast-growing quantum computing scale-up based in London founded by internationally renowned researchers from UCL and Oxford University with over 40 years’ experience in developing qubits and quantum computing architectures. Bringing together state-of-the-art cryogenic facilities and an outstanding interdisciplinary team, we are developing quantum processors based on industrial-grade silicon chips, with the potential to radically transform computing power in areas such as materials modelling, medicine, artificial intelligence and more.

Our Team

Since 2021 our team has been listed every year in the “Top 100 Startups worth watching” in the EE Times in 2021 and 2022, and our technology breakthroughs have been featured in The Telegraph, BBC and the New Statesman. Our founders are internationally renowned researchers from UCL and Oxford University who have pioneered the development of qubits and quantum computing architectures. Our chairman is the co-founder of Cadence and Synopsys, the two leading companies in the area of Electronic Design Automation. We’re backed by a team of top-tier investors, and we have recently closed our Series C funding of $160 million.

We bring together the brightest quantum engineers, integrated circuit (IC) engineers, quantum computing theoreticians and software engineers to create a unique, world-leading team, working together closely to maximise our combined expertise. Our collaborative and interdisciplinary culture is an ideal fit for anyone who thrives in a cutting-edge research and development environment focused on tackling big challenges and contributing to the development of scalable quantum computers based on silicon technology.

Our team of 100+ is based across London, Oxford, San Sebastián and Sydney, with our primary hub in Islington (London).

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 12-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.

• 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
