Payroll Specialist

Join the smartest minds in finance and technology – and keep them paid (perfectly).

As a leader in research and technology, powered by brilliant people and cutting-edge systems. From the world-class engineers and researchers building sophisticated models, to the operations experts keeping everything running smoothly – everyone plays a part in their success.

Now, on the lookout for a Payroll Specialist to join our vibrant and fast-paced team in London. You’ll be the go-to payroll expert, managing the UK payroll from start to finish, working closely with an outsourced provider, and fielding queries from some seriously smart (and very inquisitive) employees.

💼 The Role:

As the Sole Payroll Specialist, you’ll take ownership of the entire UK payroll process, ensuring our people are paid accurately, on time, and with clarity. This is a hybrid role – part operational, part advisory – ideal for someone who thrives in a dynamic, high-performing environment and loves a blend of autonomy and collaboration.

Your key responsibilities will include

• Acting as the first point of contact for all payroll-related queries across the business – from new joiners to long-serving quants.
• Managing and maintaining the relationship with our outsourced payroll provider – you’ll be the bridge between internal teams and external processing
• Owning all data collation, validation, and submission activities for monthly UK payroll (circa 400+ employees).
• Working closely with HR, Finance, and Benefits to ensure seamless integration across systems and processes
• Managing statutory reporting, pension contributions, P11Ds, and year-end activities with precision.
• Spotting opportunities to streamline and improve – because payroll should never just be “done”, it should be smartly done.

🧠 What You’ll Bring:

• Proven experience in managing end-to-end UK payroll, ideally in a sole or lead capacity
• Confidence working with an outsourced provider – you know how to manage expectations, timelines, and quality control.
• High level of attention to detail – because when you’re dealing with top talent, accuracy is everything
• Natural problem-solving ability – you don’t just find answers, you make complex things simple
• Comfortable engaging with bright, switched-on colleagues – from tech to trading, they’ll be looking to you as the subject matter expert.
• Tech-savvy and curious – we love people who ask questions, explore better ways of doing things, and embrace continuous improvement.

🚀 What’s In It For You?

• A genuinely unique opportunity to join a world-class company at the intersection of finance and technology.
• Hybrid working model – collaborate in our stunning London HQ and enjoy the flexibility of remote days.
• Competitive salary + exceptional bonus potential + outstanding benefits (seriously, our benefits are next level).
• A smart, inclusive, and supportive culture where ideas are heard and development is constant.

🧩 Smart, switched-on, and ready to make payroll your own?
