About us

VERO HR ( ) is a rapidly growing HR outsourcing business based in Peterborough providing its UK wide and international client base with a full range of people services. Technology is key to how we engage with our clients, but our service delivery is based upon combining the benefits of tech with what we do best – the personal touch.

Having achieved a strong reputation for customer service excellence (we not only won The Peterborough Telegraph Customer Service Excellence award 2023 but also recently won HR Consultancy of the Year at the 2024 Personnel Today Awards), we are always on the lookout for new team members who share our passion for great service too.

About our opportunity

“Vero Tech” is one of the nine core people services we provide as part of our HR outsourcing service. On one of our preferred systems alone, we have over 7,500 users we support, configured across 46 countries by us. Due to the expansion of demand for our Vero Tech services, we are now looking for an additional team member to join our Vero Tech team. What we are not looking for is a coder/developer. This is a role which involves implementing cloud-based software solutions rather than writing software and therefore is likely to be attractive to someone either working in HR admin role who is using HR software on a daily basis, possibly with admin/super user rights or who is already working in a similar role, looking to broaden their experience of different cloud-based systems.

Key Responsibilities

• Assisting with and leading new client system implementations, including configuring platforms and delivering user training.
• Supporting existing clients with troubleshooting, system enhancements, and general guidance.
• Collaborating with system providers to explore new modules and drive product development.
• Working alongside internal teams to ensure systems meet their needs and supporting day-to-day operations.
• Managing project updates using project management tools and contributing to both internal and client-facing meetings including user training.

Who we are looking for:

With a friendly, approachable style you will have:

• A background in either Human Resources or systems administration and support, with hands-on experience using systems and software.
• Strong technical skills, including familiarity with cloud-based systems possibly supporting API integrations
• A client-focused approach, with excellent communication skills and the ability to adapt to different situations and cultures.
• Attention to detail, a proactive mindset, and a methodical approach to project work.
• Flexibility and professionalism, with the ability to occasionally work outside regular hours if needed.

If you have a passion for the delivery of high-quality service and the ability to work in a highly organised way, then we want to hear from you!

Why you will love working here:

• An excellent salary and benefits package including life assurance, 25 days annual leave and even your birthday off!
• A very modern office environment on the outskirts of Peterborough with parking on-site and electric charging for your car.
• Excellent development/promotional opportunities with an expanding business where you can really make an impact.
• A tailored development plan and regular coaching sessions to take you to the next level, if you wish.
