- Build and nurture a high-performing team, coaching colleagues and fostering a supportive and open feedback environment.
- Collaborate with the wider Unity Advisory team to evolve firm strategy, service offerings, and market positioning.
- Represent Unity Advisory in the market, building a trusted advisor profile with clients, investors, and partners.
- Be a key part of a fast-growing disrupter in the professional services market.

- Relevant subject matter expertise including, but not limited to: Integration Blueprinting & Planning, Day 1 Readiness, Synergy Development, TSA Assessment & Management, Due Diligence, Equity Story, Target Operating Model, and IMO / Separation PMO.
- Proven track record of delivering Value Creation services within an M&A context (buy and sell side).
- Excellent project management and program orchestration skills.
- Experience with Private Equity clients and portfolio company situations.
- Strong influence and interpersonal skills, with the ability to partner with and challenge senior stakeholders.
- Entrepreneurial mindset and appetite to help build a challenger firm from the ground up.
- A hunger to build, collaborating across Unity Advisory to do so at pace.

## What you’ll get from us

- The opportunity to refine your business development skills on your terms, providing you with a clear runway to a Partner role.
