Principal (m/f/d) — Strategic People & Organization Advisory, Europe in London

Marsh People and Investment is the world's most impactful HR consulting firm. We are looking for colleagues who combine individual excellence with genuine team play. Distributed across our European offices and working as one team, we deliver strategic people work for leading multinational organizations: workforce transformation, organizational transformation and design, HR transformation, talent, and rewards. We work side-by-side with our colleagues from Oliver Wyman delivering on joint strategic client engagements, and we build our project success on unmatched workforce data and AI-enabled ways of working. Demand for advisory-led, AI-enabled people work is accelerating across Europe — and this team is being built to capture it.

As Principal, you own the answer. You lead complex client engagements end-to-end — from shaping the question with the client to defending the recommendation in the boardroom — and you carry the commercial process alongside Marsh and Oliver Wyman Partners.

What you will own:

• End-to-end leadership of client engagements: scoping, workstream design, team leadership, quality of the analysis and delivery, and the final recommendation to senior client executives — measurable, sustainable impact is your definition of done.
• A real seat at the table: you are the primary day-to-day counterpart for CHROs, transformation leaders, and their teams — building the trusted relationships from which the next mandate comes.
• Delivery across the people agenda: workforce transformation, organizational transformation and design, HR transformation, and complex talent and rewards mandates — anchored in one area, fluent across all of them.
• The commercial process, together with Partners: you shape proposals, follow-up on engagements, uncover opportunities and lead pursuits towards success – co-selling to our multinational client base alongside Partners at Marsh and Oliver Wyman.
• Team leadership and followership: you build and lead high-performing project teams across Europe, and you develop the consultants around you — apprenticeship on live work is how this team grows.
• Intellectual capital and AI-enabled delivery: you create additive thought leadership, build reusable assets, and treat AI-enabled ways of working as the default -- not the experiment.

What you bring:

• Several years (typically 8+) of consulting experience in a dynamic and demanding environment— ideally with a top-tier strategy consulting firm or a leading people advisory practice — with a consistent record of high performance.
• A track record of selling and leading client engagements end-to-end in fast-paced environments: projects you can point to with tangible client impact, delivered through teams you led.
• Credibility with senior executives: you have presented to, challenged, and won the confidence of C-level stakeholders.
• Depth in at least one of our fields — workforce transformation, organizational design and development, HR transformation and HR operating models, talent, or rewards — and genuine curiosity across the rest.
• Structured, hypothesis-driven problem solving; outstanding written and verbal communication (in English); the craft to turn hundreds of pages of analysis into the one decision the client buys.
• A mentor's instinct: role model and coach for developing talent, sparring partner for expert colleagues and clients.
• Willingness for European travel during delivery peaks.
• A completed university degree (e.g., business, economics, psychology, or a related field); an advanced degree is welcome. Fluent English is required; any further languages are a plus.

What we offer:

• A founding role. You join at the start and help shape the team's methods, standards, and culture — with visibility to European and global practice leadership from day one.
• Work that matters, at the top of the house. C-suite exposure on complex, high-stakes people mandates for Europe's most significant organizations.
• The Oliver Wyman connection. Joint pursuits and engagements with a leading strategy house within the same group — a connection no external alliance can match.
• A consulting career built to last. The intellectual intensity of top-tier consulting with a more sustainable rhythm — distributed working, European travel during delivery peaks, and a culture that expects excellence without exhaustion.
• Growth. Structured development (consulting and client-leadership programs), senior mentorship, and a transparent, merit-based progression — the natural preparation for the pathway towards Partner level.
• Flexibility and security. Mobile and flexible working, modern centrally-located offices, competitive compensation aligned to your market, and the benefits of a strong international group.
• Culture. DE&I at Marsh is lived practice, not a concept — we want everyone to feel at home here.
