Senior Account Manager – B2B

Filleigh, North Devon or Clifton, Bristol – Hybrid

Competitive Salary + Benefits

Bray Leino is a full‑service brand growth agency established in North Devon in 1973. We now have people in Bristol, London and beyond, servicing national and global B2B and B2C clients.

If you’re looking for an agency where you’ll have genuine influence, work alongside brilliant specialists and help shape the future of exciting B2B brands, we’d love to hear from you.

About The Role

We’re looking for a Senior Account Manager to join our growing B2B client services team.

This isn’t your typical account‑management role. You’ll become the trusted partner to a portfolio of leading B2B clients, helping them navigate everything from strategic planning and integrated campaigns to major events, brand development and thought leadership.

Working alongside specialists across strategy, creative, media, PR, social, SEO, PPC, content and production, you’ll be the person who brings it all together, keeping projects moving, spotting opportunities and ensuring every piece of work delivers against the client’s commercial objectives.

No two days are the same. One week you could be leading quarterly business reviews, overseeing a brand refresh and coordinating integrated campaign activity. The next, you might be delivering a large‑scale event, launching new creative assets or identifying opportunities to expand the partnership.

If you thrive on variety, enjoy building strong client relationships and love making great work happen, you’ll fit right in.

What You’ll Be Doing

  • Acting as the day‑to‑day lead for a portfolio of B2B clients, building trusted, long‑term relationships.
  • Owning account plans and ensuring activity stays aligned to each client’s business objectives.
  • Leading weekly client meetings and coordinating integrated teams across creative, media, social and digital.
  • Managing multiple projects simultaneously, ensuring everything is delivered on time, on budget and to an exceptional standard.
  • Bringing together specialists from across the agency to deliver seamless, integrated marketing campaigns.
  • Leading quarterly and annual business reviews, demonstrating impact and identifying future opportunities.
  • Identifying opportunities to grow accounts through new projects, campaigns and strategic initiatives.
  • Managing project estimates, budgets and commercial processes.
  • Reviewing creative and content before client approval to ensure quality and consistency.
  • Supporting the delivery of major events, brand development projects, thought leadership campaigns, digital assets, presentations, video content and other integrated marketing activity.

About You

  • You’ll be someone who enjoys building lasting client relationships and loves bringing people together to make ambitious projects happen.
  • You’ll probably have:
    • Agency experience in a client‑facing account‑management role.
    • Experience managing integrated marketing campaigns across multiple channels.
    • Strong commercial awareness with confidence managing budgets and forecasts.
    • Excellent organisational skills and the ability to juggle multiple priorities.
    • The confidence to lead client meetings and present recommendations.
    • A proactive mindset, always looking for opportunities to add value.
    • Experience working with B2B clients (or a genuine passion to specialise in B2B marketing).
    • A collaborative approach and the ability to inspire teams around a shared goal.
    • Most importantly, you’ll be curious, solutions‑focused and excited by the opportunity to make a real impact for clients.

And in return

  • 25 days’ holiday, increasing to 29 after two years’ service, plus Bank Holidays.
  • Company pension scheme with enhanced employer contributions after one year’s service.
  • Medical Cash Plan including an Employee Assistance Programme.
  • Employee Discount Scheme.
  • Electric Car Salary Sacrifice Scheme.
  • Outstanding training and career development, including the MISSION Group Learning Platform.
  • Employee referral scheme.
  • Regular social events.
  • Christmas shutdown.
  • Long service awards.
  • Cycle to Work scheme.
  • MISSION Share Scheme.

Inclusion Matters

At Bray Leino we believe the best ideas come from diverse perspectives and that culture only thrives when everyone has the space to show up as themselves. We’re committed to building an environment that’s welcoming, respectful and genuinely inclusive for all.

We’re proud to be a Disability Confident, Level 1 Employer. That means we’ve pledged to make our recruitment process accessible and inclusive, promote our roles widely, and offer interviews to disabled applicants who meet the minimum criteria. We also anticipate and provide reasonable adjustments where needed, because supporting every candidate matters.

If you need any adjustments to take part in the process, just let us know – we’re here to help.

Also a Part Of…

You’ll also be part of MISSION — a collective of agencies dedicated to helping clients thrive.
