Software Engineer II, Web

Amplitude•San Francisco, CA

62d•Hybrid

About The Position

Amplitude's marketing site, amplitude.com, is a core part of how we go to market. It's where prospects explore the product, where launches and campaigns go live, and where we convert traffic into trials and customers. It's also a production system - with performance, SEO, security, and reliability requirements that match our product. This role sits within the PLG + Growth Platform team, a cross-functional group focused on building the infrastructure that powers how Amplitude grows. As a web engineer on this team, you'll be responsible for the platform behind amplitude.com - a Next.js application powered by Sanity CMS and deployed via Vercel. The system supports self-serve publishing for non-technical users, but the engineering surface remains large: reusable component libraries, CMS schema evolution, structured data, rendering strategies, analytics instrumentation, and experimentation support. You'll work closely with stakeholders across Marketing, Brand, Product, and Engineering to enable fast, safe iteration on the site - while maintaining a high bar for code quality, site performance, and operational reliability. This role involves both feature work and platform stewardship: building new capabilities while also improving how the site is operated, measured, and maintained. This is a good opportunity for someone who enjoys working on company websites with real business impact, and who wants to own a high-visibility surface end-to-end.

Requirements

Have 2+ years of experience as a web or fullstack engineer, ideally on a company website or similar marketing-driven surface
Are comfortable working in a modern web stack (Next.js, TypeScript, Git, Vercel or similar)
Understand how to build reliable, maintainable systems that support rapid iteration
Have worked with headless CMS platforms (Sanity preferred) and understand schema-driven site architecture
Care about shipping things that are correct, fast, and user-friendly - even when timelines are tight
Have experience instrumenting sites for analytics and experiments
Communicate clearly with cross-functional teams and can lead scoped projects independently
Take feedback seriously, improve through iteration, and hold a high bar for your own code
Use AI tools as a force multiplier, not a crutch, and are comfortable debugging or rewriting what they produce
Show strong critical thinking and a desire to keep growing, learning, and raising the bar

Nice To Haves

Have led the technical side of a rebrand, global site rollout, or localization effort
Are comfortable navigating both the feature and platform layers of a site stack
Have worked on growth-focused systems - pricing pages, signup flows, launch surfaces
Understand how marketing sites and product surfaces work together to drive activation and conversion
Have experience improving SEO performance, rendering modes (SSG/SSR), or web accessibility in production systems
Are excited to own a high-visibility property and treat it like a product, not a static site

Responsibilities

Build and maintain amplitude.com using Next.js, TypeScript, and Sanity CMS
Design reusable page sections and evolve schema structures to support self-serve content creation
Optimize the site for performance, Core Web Vitals, SEO, and accessibility
Maintain and extend platform capabilities: CMS integrations, analytics instrumentation, Algolia indexing, and forms
Operate the site in production: triage issues, own deployments, monitor uptime, and support on-call responsibilities with clear runbooks
Ship pages and platform changes in close partnership with Marketing and Brand Design
Support feature launches, benchmarks, product release pages, and global marketing initiatives
Use AI tools like Copilot, Cursor, or ChatGPT to accelerate iteration while maintaining quality and correctness in your work
Contribute to a high-quality, fast-moving engineering culture with code reviews, documentation, and thoughtful architectural decisions
