Senior Client Delivery Consultant At-a-Glance

• Senior delivery role at a leading tax technology platform, leading complex enterprise implementations
• Deep focus on Pillar Two, GloBE and BEPS 2.0: the growth area in international tax compliance
• Hybrid working from Belfast: WFH Mondays and Fridays, office mid-week for collaboration and client days

A specialist Reg Tech platform helping multinational organisations navigate the growing complexity of Pillar Two, BEPS 2.0 and international tax compliance. Backed by a strong and growing portfolio of enterprise clients, the company is scaling its Belfast delivery function to meet significant market demand. The team combines deep tax and accounting expertise with practical technology implementation, and offers experienced consultants the autonomy, domain depth and client variety that larger organisations rarely provide.

As a Senior Client Delivery Consultant, you will lead complex, multi-workstream implementations for multinational enterprise clients, acting as the primary vendor-side delivery lead across the full project lifecycle. You will drive requirements definition, chair workshops at senior stakeholder level, manage client relationships, and provide governance oversight across your portfolio of engagements. Alongside your delivery responsibilities, you will bring domain expertise that enables you to challenge client requirements, shape solution design, and contribute meaningfully to pre-sales activities.

Pillar Two, GloBE or BEPS 2.0 exposure is highly valued: this is where the bulk of the company's current book of work sits, and candidates with direct experience in this space are rare and sought after.
