Senior Growth Marketing Manager

We’re looking for a data-driven and collaborative Senior Growth Marketing Manager to join our Marketing team. This role will sit at the center of our cross-functional growth engine—working with performance marketing, sales, customer success, design, product marketing, and content to plan and execute full-funnel marketing tests that drive measurable business impact. You will lead experimentation efforts across the customer lifecycle, from acquisition to retention, and use insights to fuel sustainable growth strategies. Your expertise in growth loops, lifecycle marketing, and performance analysis will make you a key contributor to MNTN’s continued growth trajectory.

You’re equally comfortable building a go-to-market test from scratch as you are analyzing campaign results and making recommendations to stakeholders. You have a knack for uncovering opportunities others might miss and thrive in environments that reward speed, curiosity, and iterative learning.

• Plan, execute, and optimize marketing tests across the funnel, driving customer engagement, activation, and retention.
• Collaborate with Performance Marketing, Sales, Customer Success, Product Marketing, Content, and Design teams to identify strategic opportunities and execute them with precision.
• Build and scale growth experiments across channels such as email, paid media, lifecycle programs, landing pages, and in-product messaging.
• Analyze test results to evaluate performance, extract insights, and apply learnings to future campaigns, while providing regular updates to stakeholders.
• Design scalable campaigns and lifecycle programs that boost conversions, enhance customer experience, and maximize lifetime value.
• Use data to uncover opportunities, forecast results, and clearly communicate performance metrics.
• Monitor market trends, competitive benchmarks, and emerging tools to identify new channels and growth levers.

• 5+ years of experience in marketing, with 4+ years in growth marketing focused on product-led growth or self-serve customer acquisition models.
• Demonstrated success in building and optimizing full-funnel marketing campaigns that drive measurable business results.
• Strong grasp of growth frameworks, conversion rate optimization, segmentation, and performance metrics.
• Proven ability to collaborate across functions and manage multiple campaigns simultaneously.
• Excellent analytical skills with experience using platforms like GA4, Crazy Egg, Marketo, Tableau, or similar tools to inform decisions.
• A test-and-learn mindset. You’re not afraid to experiment, fail fast, and iterate toward success.
• High sense of ownership. You take initiative, follow through, and hold yourself accountable to outcomes.

• Experience in a SaaS or B2B tech company.
• Familiarity with marketing automation, personalization tools, or customer data platforms.
• Background in ad tech, martech, or the digital media ecosystem.
