Web Growth Marketing Manager

About The Role & Team You'll own one of our most critical growth levers — amplitude.com — with impact on strategy, not just execution. You'll work on the frontier of AI-powered marketing. We're actively integrating AI-native workflows across everything we build. And we recently partnered with Statsig to expand our experimentation portfolio. You'll have dedicated resources: web engineers and brand/growth designers who are aligned to this function — so you can move fast and build with craft. You'll sit within a larger integrated marketing team, giving you broad leverage across campaigns, product launches, and PLG and sales pipeline initiatives. Amplitude is the category leader in digital analytics and experimentation — and you'll be one of its most expert users, running experiments and optimization using the very product we sell. As a Growth Marketing Manager you will: Website Strategy & Ownership Own amplitude.com as a strategic growth engine — defining site architecture, user journeys, and content strategy that drives both self-serve growth and enterprise pipeline. Build a forward-looking roadmap grounded in performance data, experimentation insights, and a clear POV on what moves the business. Own and scale the Sanity CMS platform, building it into a self-serve system that empowers teams across the org to publish independently. Conversion & Experimentation Design and continuously optimize conversion-focused experiences across product pages, pricing, demo request flows, and campaign landing pages. Lead experimentation and measurement strategy using Amplitude Analytics and Web Experiment to improve engagement, conversion, and pipeline generation across web surfaces. Analyze website-attributed pipeline in Salesforce, surfacing trends across GTM segments and win/loss patterns to guide investment decisions. Cross-Functional Partnership Partner closely with web engineering to ship new capabilities — you're a peer in the build process, not a gatekeeper. Collaborate across Marketing, Product, Growth, Sales, and Engineering — navigating tradeoffs with a clear business POV and strong stakeholder communication. Shape repeatable, scalable approaches for product launches and campaign experiences that maintain a high bar for performance and brand consistency. AI-Native Ways of Working Introduce and operationalize AI-native workflows (Claude, Claude Cowork, Claude Code) to accelerate content creation, site improvements, and operational efficiency. At a minimum, you need to have: 3–5 years of hands-on experience owning or co-owning a corporate website or web growth program for a SaaS, AI, or tech company. Demonstrated experience working directly with engineering teams — you know how to scope, prioritize, and collaborate in a technical environment. Strong experimentation mindset: you've run A/B tests and conversion optimization programs on corporate or product marketing sites. Data-driven by nature — you make decisions from evidence, not intuition alone. Experience with Amplitude or a comparable analytics platform is a strong plus. Experience with a headless CMS (Sanity experience a bonus; Contentful, Prismic, or similar all count). Excellent cross-functional communicator who can align stakeholders across Sales, Product, Engineering, and Marketing. You'll be a great addition to the team if you have: Background in a growth-stage startup or scaling SaaS/AI company — you're comfortable with ambiguity and know how to build systems where none exist. Familiarity with AI products or AI-native workflows — bonus if you've worked at an AI company or integrated AI tooling into your marketing operations.
