Human Resources Administrator

About Us
At algo1, we are reinventing one of the world’s most familiar experiences: the in-store grocery trip. We are building an AI-native product that understands each shopper, responds to their context in real time and makes an everyday experience less stressful, more personal and more engaging.

We’re backed by leading investors and founded by two entrepreneurs: one with a track record of building companies, and the other a recognised leader in data and analytics. Together, they have brought together frontier AI researchers and engineers, product and strategy leaders, and senior operators from major UK and US grocery businesses.

The people who join now will have an opportunity to shape the product, the engineering culture, and what algo1 becomes.

The Role
This role reports to our Chief of Staff and works closely with our leadership team and hiring managers across the business. It is part-time and currently set at two days per week (0.4FTE).

You’ll keep our people operations running smoothly as we grow, from the moment a candidate accepts an offer to the everyday policies, systems and reporting that help our team do their best work. You’ll make sure the details are right, the paperwork is compliant, and every new joiner gets a great first impression of algo1.

What You’ll Own

• Keep people operations running smoothly. Own the day-to-day HR administration, from preparing offer letters and employment contracts to managing employee records, documentation and onboarding.

• Support hiring and onboarding. Coordinate the operational side of bringing new people into the business, ensuring contracts are signed, checks are completed and new joiners have a great experience from day one.

• Manage right to work and visas. Carry out right to work checks, coordinate visa and sponsorship processes where required, and maintain accurate, compliant records.

• Support performance management. Help us run effective performance review processes, support managers with feedback and performance conversations, and ensure appropriate documentation and follow-up.

• Provide practical HR guidance. Be a trusted first point of contact for everyday people questions, helping managers and employees navigate policies, processes and employee matters with sound judgement and discretion. Know when to escalate more complex issues or seek specialist advice.

• Maintain policies and compliance. Keep our people policies, employee documentation and HR processes up to date, practical and appropriate for a growing UK business.

• Own our people systems and data. Maintain accurate records, manage our HR tools and keep people reporting organised and reliable.

• Help build a great place to work. Contribute to employee engagement, culture and people initiatives, bringing ideas that are thoughtful, proportionate and suited to a growing startup.

• Improve how we work. Spot opportunities to simplify, automate or improve our people processes, and support the Chief of Staff on ad hoc people and operational projects.

About You
