Sinch is looking for a Senior Growth Marketing Manager to own the self-serve acquisition funnel at Sinch Mailgun. You'll be responsible for driving qualified traffic to the site, optimizing the conversion experience, and turning visitors into signups and trials. This role sits at the center of our product-led growth PLG motion, working cross-functionally with performance marketing, content, growth and operational teams to accelerate acquisition while improving funnel efficiency.

Responsibilities

• Own the self-serve acquisition funnel from first visit to signup/trial. Lead CRO across key pages, run experiments, reduce friction, and partner with performance marketing to make sure paid traffic has somewhere effective to land.
• Develop and execute a strategy to protect and grow organic presence, covering both traditional SEO fundamentals and LLM/AI Engine Optimization (AEO).
• Own the weekly and monthly reporting cadence for the acquisition funnel: traffic by channel, site conversion, and signups. Know the numbers cold and contextualize them for leadership.
• Manage marketing systems and tools, leveraging your technical knowledge to optimize web analytics and automation platforms.
• Maintain and optimize the Mailgun website in WordPress, working directly with our web developers and designers to ship page updates, landing pages, and CRO improvements.

Requirements

• 5+ years of growth, digital, or acquisition marketing experience, ideally at a developer-tools, SaaS, or API-first company with a PLG motion.
• Deep CRO instincts. You've optimized signup flows, run A/B tests on landing pages, and think in terms of conversion rates, not just traffic volume.
• Strong analytical skills. Comfortable in GA4 and Looker. You can pull your own data, spot anomalies, and build a narrative from numbers.
• SEO fundamentals and emerging AEO awareness. You understand how search is changing with zero-click results, AI overviews, and LLM referral traffic, and have ideas about how to adapt.
• WordPress CMS proficiency. Comfortable managing page content, URLs, and redirects, and collaborating with web developers to ship changes.
• Bias toward action with sound judgment. Able to ship things and make calls with imperfect data on a lean team, while knowing when something warrants deeper investigation.

The annual starting salary for this position is between $100,000.00-$120,000.00 Factors which may affect starting pay within this range may include geography/market, skills, education, experience, and other qualifications. This role will be accepting applications until 06/29/2026 at a minimum. Please note that the application timeline may be flexible to accommodate a comprehensive candidate evaluation.

This role is remote. Relocation and visa sponsorship are not available for this role
