As one of the UK’s leading law firms, we’re here for the people and businesses who rely on us at life’s important moments - made possible by our colleagues who bring the expertise, judgement and care that makes the difference.

Our colleagues bring Irwin Mitchell to life every day, so it matters that you feel valued from the very first day and are trusted with the responsibility, in the right culture, to do the best work of your careers.

As an HR Assistant, you'll join our friendly and supportive People Services team, the first point of contact for a wide range of HR queries across the business. Whilst we're a small team, we're a busy one, providing essential support throughout the employee lifecycle.

• Knowledge of pre-employment screening processes and right to work requirements.
• A professional, approachable and confidential manner, with the ability to handle sensitive information appropriately.
• Strong attention to detail and the ability to work accurately and efficiently.
• Excellent communication and relationship-building skills, with the confidence to support colleagues at all levels across the business.
• A collaborative approach and willingness to share ideas, knowledge and best practice with the wider team

• 25 days' holiday as standard, rising to 28 days depending on role level, plus bank holidays and the option to purchase additional leave.
• Opportunities to share in our success through annual pay and bonus review processes for eligible colleagues.
• Health and wellbeing support, including Westfield Health and Digital GP access. 
• Competitive pension arrangements to help you plan for the future. 
• Two paid volunteering days every year to support causes that matter to you.
