The Company

Mozaic is an innovative and growing Digital Transformation consultancy. We work with large organisations to assess and transform their digital operations.

We have an outstanding reputation, with customers across industries including Financial Services, Government and Defence. Our Enterprise Platforms practice helps organisations design, implement and improve modern service management platforms and ways of working.

The Role

We are looking for an experienced Halo Developer to join our Enterprise Platforms practice, working with customers to configure, develop and improve solutions on the Halo platform.

This role is aimed at someone who already has practical Halo experience and can become productive quickly. We are looking for at least 6 months of hands-on experience administering, configuring or developing within Halo ITSM rather than a traditional software development background.

You will work across customer implementations and improvements, translating requirements into practical Halo configuration while following good service management and platform design principles.

Background & Experience

You should have:

  • At least 6 months of hands-on experience administering, configuring or developing in Halo ITSM
  • Experience configuring ticket types, workflows, actions, fields and service catalogue items
  • Experience working with users, agents, teams, organisations, sites and access or permissions within Halo
  • A good understanding of core ITSM processes including incidents, requests, problems, changes, assets and knowledge
  • Experience configuring notifications, templates, SLAs or other day-to-day platform functionality
  • Experience troubleshooting configuration issues and working through problems logically
  • The ability to understand customer requirements and translate them into maintainable Halo configuration
  • Good written and verbal communication skills and confidence working with customers and stakeholders
  • The ability to document configuration and work effectively as part of a wider delivery team

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

Start with a chat, not a search bar

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.

What We're Looking For

We are not looking for a heavyweight software engineer. We are looking for someone who knows their way around Halo, understands how service management platforms are configured and can take a requirement through to a sensible working solution.

You should be comfortable owning configuration tasks, asking the right questions when requirements are unclear and continuing to develop your Halo technical skills through real customer delivery.

Reward Package

We offer a competitive reward package, collaborative culture and fulfilling client engagements that will help you develop your career.
