Senior Content Marketing Manager, Sales-Led

Job Description

Hi, I'm Sterling, VP of Demand Generation at Customer.io. We're looking for a strategic content marketer to support our sales-led growth and help mid-market buyers understand our platform's unique value.

As our Sales-Led Growth Content Marketing Manager, you’ll create persuasive, persona-driven content that empowers our partner and sales teams to connect with growth-minded marketing and operations leaders. You'll craft assets that move deals forward in a considered but fast-paced buying process, including owning the development of our annual State of Messaging report - from sourcing surveys to organizing data while maintaining consistency with our established methodology.

Key Responsibilities:

  • Develop mid- and bottom-of-funnel content, including case studies, comparison guides, ROI briefs, and sales one-pagers, to support sales conversations.
  • Collaborate with AEs, PMM, and solutions engineering to translate technical features into clear business value across verticals like SaaS, mobile apps, fintech, and healthtech.
  • Build messaging frameworks and enablement assets that help our team speak to the specific needs of marketing and lifecycle teams at product-led and customer-centric companies.
  • Partner with sales to execute targeted, persona-specific nurtures and content creation that supports high-conversion outbound and follow-up campaigns.
  • Support cross-functional campaigns and ABM initiatives with content tailored to industries, use cases, and company maturity levels.
  • Measure content impact on sales performance, including partner recruitment, close rates, and pipeline acceleration.

About You:

  • 3–5 years of B2B SaaS content marketing experience, ideally supporting sales cycles for mid-market and early enterprise buyers.
  • Strong grasp of technical marketing concepts (e.g., marketing automation, behavioral data, customer messaging orchestration).
  • Experience collaborating with sales and customer-facing teams to develop high-impact enablement materials.
  • Skilled at writing for multiple personas, especially growth marketers, marketing ops, and technical decision-makers.
  • Comfortable with fast-paced, feedback-driven environments and adapting content to evolving sales strategies.

What Sets You Apart:

  • Familiarity with the buying cycles of mid-market companies and early-stage marketing teams.
  • Ability to simplify complex product capabilities while still appealing to the broadest possible technically-savvy audience.
  • Success creating content for SaaS buyers evaluating solutions without extensive procurement teams.
  • Experience with CRM, enablement, or ABM tools to understand what content resonates and converts.
  • Proven track record building assets or enablement material that speed up sales cycles and support high-conversion outbound.

Safe Remote Job Search Tips

Verify Employer Thoroughly

Research the company's identity thoroughly before applying. Check for a professional website with contacts, active social media, and LinkedIn profiles. Verify details across platforms and look for reviews on Glassdoor or Trustpilot to confirm legitimacy.

Never Pay to Get a Job

Legitimate employers never require payment for applications, training, background checks, or equipment. Always reject upfront payment requests or demands for bank details, even if they claim it's for purchasing necessary work gear on your behalf.

Safeguard Your Personal Information

Protect sensitive data like SSN, bank details, or ID copies. Share this only after accepting a formal, written job offer. Ensure it's submitted via a secure company system or portal, never through insecure channels like standard email attachments.

Scrutinize Communication & Interviews

Watch for communication red flags: poor grammar, generic emails (@gmail), vague details, or undue pressure. Be highly suspicious of interviews held only via text or chat apps; legitimate companies typically use video or phone calls.

Beware of Unrealistic Offers

If an offer's salary or benefits seem unrealistically high for the work involved, be cautious. Research standard pay for similar roles. Offers that appear 'too good to be true' are often scams designed to lure you into providing information or payment.

Insist on a Formal Contract

Always secure and review a formal, written job offer or employment contract before starting work or sharing final personal details. Ensure it clearly defines your role, compensation, key terms, and conditions to avoid misunderstandings or scams.
