About Mimecast
The work people build is worth protecting, and it's harder to protect than it used to be. AI agents now move at machine speed with human-level access, and a small slip-up can become a very public one. We disrupt cybercriminal activity before that happens. We think fast, go big, and always demand more of ourselves. We work hard, deliver, and repeat. We grow with real determination and put success well within reach. We push each other to be better and expect to be pushed back, in a community built on respect, where everyone is counted. Work Protected.
Overview
The Senior Manager, Design is a GTM-focused design leader responsible for producing creative work that drives engagement, builds market interest, and supports Mimecast’s demand generation engine across every channel. This is not a conceptual role. It is an execution role with taste — someone who understands how B2B enterprise buyers respond to visual communication, and who builds creative that earns attention and creates interest in a sophisticated, skeptical audience.
This role sits within the design function, reporting to the Director of Brand, and works in close partnership with Demand Generation, Marketing Operations, Field Marketing, and Sales Enablement. You will set the creative standard for how Mimecast shows up across paid media, campaigns, events, digital, and sales materials — directing in-house designers, external agencies, and AI-assisted workflows to deliver at speed without sacrificing quality.
The best candidate for this role is a proactive facilitator, not a passive service-designer. You build relationships across the company using design as a trust-building exercise. You make the brand feel accessible and alive to the teams who rely on it most.
