Senior Consultant
Hybrid working - Remote + On-Site in the UK
Full-Time, Permanent (UK working permit required)
Who We Are
We are a Business Transformation Consultancy, passionate about supporting our clients with their transformation challenges and optimising how they work through the effective use of technology. Our goal is to help our clients realise true value from their investment.
We are growing quickly but continue to set the bar high. We are looking for consultants who combine strong delivery capability with curiosity, accountability and a desire to create meaningful impact for clients.
As an Employee-Owned Trust (EOT), our people are at the heart of everything we do. Everyone has a stake in our success, a voice in how we operate, and a shared responsibility to act with integrity, ambition and care.
The Role
This role is designed for an experienced consultant with at least five years’ experience who can lead complex delivery and act as a trusted advisor to senior stakeholders.
You will take ownership of end-to-end delivery across large-scale and complex transformation initiatives, ensuring alignment to strategic objectives and measurable business value. This includes leading multi-workstream initiatives and managing complexity across stakeholders, teams and dependencies.
We work closely with our clients and typically operate in a hybrid model, with time spent on-site to build strong relationships and support delivery where it matters most.
Professional Consulting Expectations
As a consulting professional, your role extends beyond delivering high-quality client work. You will also contribute to Lean Tree’s growth, reputation and commercial success by building trusted client relationships, identifying opportunities to create additional value, supporting business development and proposals, sharing knowledge and strengthening our consulting capabilities.
Every consultant plays a part in generating future revenue by recognising client needs, identifying new opportunities, supporting account growth and contributing to market insights or thought leadership. Success is measured not only by client delivery, but also by your contribution to the firm’s long-term growth, profitability, capability and culture. Consultants at all levels are therefore expected to think commercially and understand that sustainable success depends on both excellent delivery and the development of future opportunities.
In addition to client delivery responsibilities, Senior Consultants should routinely identify opportunities to create additional client value, shape opportunities into potential engagements and work alongside senior colleagues to secure follow-on business. Senior Consultants are expected to play a visible role in developing the firm's intellectual property, coaching junior colleagues and enhancing the firm's reputation in the marketplace.
