Job Summary:

Job Description:

Role Title: HR Manager
Hours of Work: 20 per week, worked flexibly across a minimum of 3 days
Location: Hybrid, with at least 1 day per week from our office in Coleshill
Reports to: CEO of Aion

Due to continued growth and transformation, Aion is looking to appoint a part-time HR Manager to own and deliver day-to-day people operations across the employee lifecycle, while supporting managers with practical, proportionate guidance.

Organisational Context

Aion is a business unit within Volaris Group. We build the software that powers university timetabling — the civic infrastructure that shapes the rhythm of learning, kept running by the often-invisible experts who make every term, lecture and exam fit together.

Aion brings together Celcat in the UK and Bullet Solutions in Portugal: a focused software business that timetables education around the world, and part of Volaris Group's international portfolio of vertical market software companies. Volaris provides the group infrastructure (HR systems, governance frameworks, reporting standards and learning programmes) while Aion operates with local accountability, aligned to group standards and systems.

We are an AI-first organisation, and we'll help you get up to speed with tools like Copilot, ChatGPT and Claude Cowork.

Working Style & Environment

We are a growing and evolving business. We are looking for someone who is energised by change, comfortable working with ambiguity, and confident building structure as the organisation scales.

This role suits a commercially minded HR professional who can balance strategic thinking with practical delivery. You will be comfortable operating in an environment where priorities evolve, processes continue to mature, and collaboration across teams is essential.

You will help create clarity, alignment and momentum across the business whilst ensuring our people practices remain pragmatic, scalable and people focused.
