We’re Twenty One Twelve, a high-performing B2B marketing agency helping tech, fintech, and financial services companies engage hard-to-reach audiences. Following sustained growth, we’re looking for an experienced Senior Account Manager to help us deliver exceptional client work while supporting the development of our growing delivery team.

You’ll lead several high-value accounts, working with CMOs, founders, and leadership teams to plan and oversee campaigns. You’ll coordinate our in-house content, design, and implementation specialists—ensuring we deliver the right work, on time, with impact.

We are still small, so this position will suit someone who is still willing and able to get their hands dirty and support implementation of client work. You’ll also support agency growth by working closely with the founder to develop processes, grow accounts, and elevate delivery standards.

  • Own client relationships for multiple retained accounts (typically in tech/FS)
  • Conduct performance reviews, strategic planning sessions, and reporting calls
  • Spot upsell/growth opportunities with existing clients
  • Support and mentor junior team members
  • Support the founder with growth initiatives and business planning

Requirements:

  • 5+ years in a B2B agency or consultancy with experience across multiple client sectors
  • Track record managing multi-channel campaigns (email, social, paid, content, events)
  • A bias for ownership, problem-solving, and commercial thinking
  • Experience in SaaS, fintech, or financial services or other complex B2B sectors
  • Confident briefing design, content, and outreach elements

Flexible working (part-time or full-time). High-quality client base in interesting, complex sectors.

Send your CV and a short note (or Loom video) explaining your fit to info@2112.
