The opportunity
As a Senior Consultant at Proxima, you will lead complex workstreams within our Professional Services category and manage senior stakeholders while delivering innovative solutions and mentoring junior consultants. You will be part of client-facing teams delivering high-impact commercial, sourcing, and supplier initiatives, supporting the development of insights, contributing to solution design, and playing an active role in delivering outcomes, not just recommendations.

This is not a passive learning role. At Proxima, we are practitioner-consultants. You will build experience quickly, take responsibility early, and work alongside clients to deliver real, measurable change.
