The RoleWe are looking for Consultant Systems Engineers who are comfortable operating across business, operational, and technical domains to shape integrated solutions to complex problems.

Working at RaptorAs a growing consultancy, you will have real influence over both client outcomes and how we operate as a business. You won’t be one of many layers in a large organisation, you will:

Work directly with senior clients on meaningful problems

Have visible impact on engagements and outcomes

Contribute to shaping our ways of working and growth
