Senior Partner Manager

The Role After 33+ years of excellence, Leighton are on our next chapter of growth, and we need a commercially sharp, relationship-driven Senior Partner Manager to play a pivotal role in that journey. You will be the commercial engine behind some of our most significant partner relationships. This is a revenue-carrying role with a personal target, your primary focus is net new growth: originating opportunities, building and executing GTM plans with partners, and winning enterprise-scale work alongside the world’s largest consultancies and system integrators. This is not a delivery role. You will be the strategic and commercial presence within partnerships, ensuring existing programmes are healthy, relationships are thriving, and that every engagement becomes a platform for the next opportunity. You will be given the chance to grow and develop within Leighton as we continue to drive commercial success whilst always maintaining outstanding company culture. Manage and Deepen Existing Partner Relationships Own the day-to-day and strategic relationship with a portfolio of major consulting and SI partners, including some of the largest firms in the world. Act as the single commercial point of contact for your partner portfolio, building trusted relationships at multiple levels within each organisation. Lead regular business reviews and joint planning sessions with partner stakeholders to ensure alignment, momentum, and mutual accountability. Monitor the health of active programmes of work being delivered alongside partners, not as a delivery manager, but as the commercial owner who ensures things are on track, relationships remain strong, and risks are surfaced early. Resolve commercial tensions and navigate partner dynamics with confidence and diplomacy. Find and Develop New Opportunities Within Partners Proactively identify new commercial opportunities within your partner ecosystem, whether that is new practice areas, new geographies, or new buyer relationships within each firm. Develop a deep understanding of each partner’s go-to-market strategy and identify where Leighton’s capabilities can add value. Build and maintain a pipeline of partner-sourced and partner-influenced opportunities, working closely with the Business Development team to progress and close them. Represent Leighton at partner events, workshops, and industry forums to raise our profile and generate new leads. Grow End Client Accounts Where Leighton is already delivering work alongside a partner for an end client, actively identify opportunities to develop a direct and expanded relationship with that client. Work strategically to move Leighton from being a subcontractor into a trusted partner in our own right with enterprise-scale end clients. Collaborate with pre-sales and Business Development to craft compelling propositions for end clients that go beyond the current scope of work. Build relationships with senior stakeholders at end clients to uncover additional needs, new workstreams, and longer-term strategic opportunities. Drive Commercial Performance Carry a personal revenue target and take full accountability for delivering against it through net new opportunity origination and account growth across your partner portfolio. Create and own joint GTM plans with each partner, defining target sectors, propositions, and go-to-market motions, then driving execution with the support of Marketing, pre-sales, and the wider Business Development team. Proactively originate new opportunities, not just respond to inbound, by building relationships deep inside partner organisations and converting them into qualified pipeline. Feed market intelligence back into the business to inform our positioning, proposition development, and strategic priorities. Knowledge Skills & Abilities What You'll Bring A proven track record managing strategic partnerships or alliances with major global consultancies, Big 4 firms, or large Sis, and the ability to navigate complex, matrixed organisations with confidence. Experience creating and owning partner growth plans, setting joint objectives and defining GTM motions. Strong commercial acumen and a genuine hunger to grow revenue, you see every partner relationship as an opportunity, not just something to maintain, and you know how to convert relationships into pipeline. Experience shaping large, complex, multi-stakeholder deals, you can navigate enterprise procurement, influence senior decision-makers, and bring internal teams together to construct and close significant opportunities. A background in consultative or technology services sales, you are comfortable selling outcomes and expertise rather than products, and you understand how large organisations buy professional and technical services. Self-motivated and ambitious, energised by building something significant rather than managing the status quo. You build trust with internal stakeholders as readily as external ones, and know how to orchestrate pre-sales, delivery, and executive teams around a shared commercial goal. Comfortable with regular travel and the demands of senior enterprise partnerships, when a critical pitch requires it, you want to be there. Success Metrics Strong, active relationships with key contacts across your partner portfolio at multiple seniority levels. A consistent pipeline of new opportunities originating from or influenced by your partner relationships. Measurable expansion of Leighton’s commercial footprint within existing partner-adjacent end clients. Partner-sourced and partner-influenced revenue that grows year-on-year. Active programmes of work alongside partners are commercially sound and risks are identified and managed proactively. Who You Will Work With Reporting directly to the Head of Business Development, you will be a significant part of the Business Development Team. Day-to-day you will collaborate closely with the Chief Revenue Officer, Head of Marketing, and our technical leadership team, working together to shape propositions, build pipeline, and ensure what we take to market is compelling, credible, and backed by world-class delivery capability. This is not a ‘lone wolf’ role. You will be supported, resourced, and empowered, but you will also be expected to lead, influence, and drive outcomes across both partner organisations and within Leighton.
