Deployment Lead - Accounting Solutions - UK

Who We Need

We are building industry-defining accounting and finance software. We are looking for a proactive, detail-oriented Deployment Lead to join our team and help lead the successful onboarding of new customers onto Rillet.

This role is ideal for someone with a strong accounting foundation who is excited to work directly with customers and help finance teams modernise how they operate. You may come from Big Four audit, accounting advisory, finance transformation, or an operational accounting role at a high-growth technology company. You do not need to have formally led ERP implementations before, but you do need to be systems-minded, highly organised, customer-oriented, and eager to learn quickly in a fast-paced startup environment.

What You'll Do

• Lead key parts of customer onboarding and deployment, helping ensure a smooth and timely implementation experience.

• Partner with internal teams across Product, Engineering, and Customer Success to execute implementation plans and solve customer problems quickly.

• Learn and analyse client accounting and finance workflows, then translate those needs into clear requirements and practical solutions.

• Guide customers through onboarding, training, change management, and adoption.

• Support data migration, reconciliations, systems setup, and integration coordination.

• Track milestones, drive follow-through, and keep internal and external stakeholders aligned throughout the onboarding process.

• Identify risks early, escalate issues quickly, and help keep customer launches on track.

• Build trust with customers by being responsive, thoughtful, and solutions-oriented.

• Maintain clear documentation and provide regular status updates to customers and internal stakeholders.

Who We're Looking For

• Meaningful experience in accounting, audit, advisory, finance transformation, or a related customer-facing role.

• Strong accounting foundation, with the ability to speak credibly about financial close, reconciliations, revenue recognition, and core finance workflows, including familiarity with UK GAAP and IFRS.

• Excellent communication skills and the presence to work directly with customers and senior stakeholders.

• Systems-minded and excited to learn implementation work, even if you have not formally held an implementation title before.

• Strong organisational and project management skills, with the ability to manage multiple workstreams at once.

• Comfortable operating in a fast-paced environment while maintaining high attention to detail.

• Experience working cross-functionally with technical and non-technical teams.

• Experience at a Big Four firm, SaaS company, or high-growth technology company is a plus.
