Senior Manager, Field & Experiential Marketing in London

Company Overview: Radiant is redefining how AI infrastructure is built. We design and operate AI-native cloud platforms engineered for sovereignty, performance, and scale. Our infrastructure powers GPU-native workloads, multi-tenant control planes, and high-performance AI systems designed for the most demanding environments. We are not building a generic cloud. We are building purpose-built AI infrastructure - from powered land, to compute, to software.

As we scale our platform and expand our engineering organisation, we are looking for leaders who can build strong teams, uphold high standards, and deliver reliably at pace.

Job Overview: Radiant is building a category-defining AI infrastructure company that projects itself on the global stage as well as in intimate settings. We are looking for a Senior Manager, Field & Experiential Marketing to own that presence end to end. This role is responsible for ~35 events annually, spanning:

• Global flagship conferences and trade shows (GTC, GITEX, Raise, AI Summit, etc)
• Executive dinners, briefings, and private roundtables
• Strategic association partnerships
• Webinars and owned media (including our podcast)

You will design and execute events that feel intentional, elevated, and unmistakably on brand—whether that’s a 40x40 booth at a major industry conference or a 12-person dinner with senior decision-makers. This is a hands-on leadership role. You will set the vision, sweat the details and ensure every event earns its place in the GTM strategy with reportable ROI.

What You’ll Own

• Event Strategy & Portfolio Ownership: Own the full annual event calendar, ensuring each event aligns to clear business goals: pipeline creation, executive engagement, category leadership or partner expansion. Define the right mix of large-scale conferences, targeted field programs, owned experiences, and virtual events. Evolve Radiant’s event strategy year over year as the company scales.
• Flagship & Field Event Execution: Lead end-to-end planning and execution of conferences, trade shows, executive dinners, briefings, and roundtables. Elevate booth presence, themes, and storytelling—moving beyond “table stakes” to experiences that invite conversation. Manage all logistics: exhibitor services, vendors, shipping, timelines, on-site setup/teardown, and contingency planning. Ensure every event—large or small—feels deliberate, polished, and aligned with our brand.
• Executive & Senior-Audience Experiences: Design and deliver small-room, high-seniority events that prioritize substance, discretion, and peer-level dialogue. Partner with leadership, sales, and product to shape agendas, talking points, and attendee experience. Develop repeatable executive-event playbooks that scale without losing quality.
• Sales Alignment & Revenue Impact: Work closely with Sales and SDRs on pre-event outreach, meeting setting, and account prioritization. Ensure teams show up prepared with the right messaging, materials, and attendee context. Own post-event follow-up coordination, lead flow, and performance tracking. Maintain a clear line of sight between events, pipeline influence, and revenue impact.
• Webinars & Podcast Operations: Run the operational side of webinars: platforms, speakers, rehearsals, live execution, and follow-up. Coordinate recording logistics for Radiant’s podcast, including scheduling, production support, and asset handoff. Continuously improve quality, consistency, and operational efficiency.
• Measurement, Operations & Continuous Improvement: Enrich attendee and account data before and after events. Track and report on leads, pipeline influence, cost per lead, and qualitative outcomes. Use data and feedback to refine formats, themes, partners, and investments. Bring curiosity—especially around AI and automation—to reduce repetitive work and improve execution velocity.

What Success Looks Like

• Radiant’s events are recognized internally and externally as thoughtful, premium, and purposeful.
• Sales teams view events as a reliable, well-orchestrated revenue lever—not a logistical burden.
• Executive events consistently attract the right senior audiences and lead to meaningful follow-on conversations.
• Event performance is measurable, explainable, and improving year over year.
• Ability to handle high-pressure situations with key stakeholders.
