We build technology to improve lives in Africa. We're currently focused on 390 Work, software that helps businesses organise and run their operations, covering sales, inventory, finance, customers, approvals, and team responsibilities.


We’re hiring a Senior Product Marketing Manager to help more businesses understand what 390 can do for them and give them good reasons to choose it.


About the role

You’ll own how we position and communicate 390 Work. That includes understanding our customers, deciding which problems to lead with, planning product launches and turning those decisions into useful marketing.


Our product covers several parts of a business, so knowing what to explain first matters. A business owner looking for better inventory control may need a different introduction from an operations manager trying to organise purchasing and approvals. You should understand those differences and shape the message accordingly.


You’ll work closely with the founder, product team and colleagues handling demos and onboarding. We expect you to spend time using the product, speaking with customers and listening to the questions that come up before and after someone signs up.


You’ll also produce work yourself. The job includes writing a product page, developing a campaign brief, interviewing a customer, or reviewing a video script.


What you’ll be responsible for

  • Research our customers and prospective customers to understand their needs, how they choose software and what makes them hesitate.
  • Develop positioning and messaging for 390 Work and the customer groups we choose to focus on.
  • Plan and deliver product launches and feature announcements, with a clear audience, message, rollout plan and measures of success.
  • Write and improve website copy, landing pages, product emails, customer stories and other marketing materials.
  • Guide product content and campaigns across Instagram, LinkedIn and email, working with designers and video producers to bring the ideas to life.
  • Develop practical examples, presentations and supporting materials for the people handling enquiries, demos and onboarding.
  • Work with the product and customer teams on communications that help new customers get started and existing customers use relevant parts of 390.
  • Track competing products and the alternatives customers already use, and use that understanding to improve our messaging.
  • Review campaign and customer data to understand which messages attract suitable businesses, lead to useful conversations and contribute to paid adoption.


What we’re looking for

You should have at least five years of relevant marketing experience, including direct responsibility for product marketing at a B2B software or technology company.


We’ll look for evidence that you have:

  • Led positioning, messaging or a product launch and can explain the decisions you made.
  • Used customer research to change a message, campaign or marketing approach.
  • Wrote strong product copy yourself. You should be able to explain a detailed product in language a business owner or manager understands.
  • Worked closely with product teams and learned enough about a product to communicate its capabilities accurately.
  • Managed a project from the initial idea through production, release and review.
  • Assessed results beyond reach and engagement, including enquiry quality, conversion, and customer adoption.
  • Worked independently, set priorities and followed through in a small team.


Experience with ERP, CRM, accounting, inventory or other business management software would be useful.

Your previous job title matters less than the work you have owned. We’ll want to understand your personal contribution to the examples you share.


Assessment

If shortlisted, you'll need to submit two examples of product marketing work you have contributed to. These could include a product launch, website page, campaign, customer story or email sequence.


For one example, briefly explain:

  1. Who the product was for and what you were trying to achieve.
  2. What you personally handled.
  3. What informed your approach.
  4. What happened, how you measured it and what you learned.


Please remove any confidential information before sharing.


You will walk us through your work and complete a short product messaging exercise.
