Sr. GTM Engineer, Marketing

About the role

We're hiring a Sr. GTM Engineer, Marketing to transform Hiya's website into an AI-powered, revenue-driving digital growth engine. This role sits at the intersection of marketing, engineering, and product—responsible for leading our migration from Webflow to a headless CMS architecture while partnering closely with Marketing leadership to bring positioning, campaigns, and GTM initiatives to life through high-performing digital experiences.

What You'll Do

• Own the end-to-end buyer journey across awareness, consideration, and conversion stages, translating positioning and campaign strategy into compelling, high-converting web experiences
• Lead migration from Webflow to a modern headless CMS (e.g., Contentful, Sanity, Storyblok), architecting a scalable React/Next.js-based frontend that maintains strong engineering standards while enabling marketing speed
• Build modular systems that enable rapid deployment of campaigns and landing pages, increasing experimentation velocity across enterprise and PLG segments
• Integrate AI agents and LLM APIs to power dynamic content generation, personalized experiences, SEO/GEO optimization workflows, and scalable localization—reimagining what's possible in digital marketing
• Architect and implement event tracking, data layers, and attribution frameworks, maintaining hands-on ownership of tools such as Google Analytics 4, Amplitude, and Google Tag Manager
• Ensure clean data flow between website, CRM, marketing automation, and PLG systems, aligning web experimentation with paid, organic, lifecycle, and product initiatives
• Develop hypotheses and testing roadmaps to improve performance of top pages, owning website KPIs and making tradeoffs between speed, quality, and scale
• Maintain best-in-class mobile and desktop experiences, Core Web Vitals, performance benchmarks, UX clarity, messaging effectiveness, and accessibility standards

What Success Looks Like

• Hiya's website becomes a measurably stronger growth driver—improving traffic, engagement, conversion rates, and pipeline contribution in ways that directly support company OKRs and revenue goals
• The headless CMS migration is completed on time and establishes a foundation that scales globally, supports rapid experimentation, and reduces friction for marketing and engineering teams
• AI-powered capabilities (personalization, content generation, localization) are integrated thoughtfully and measurably improve performance, demonstrating clear ROI and setting the standard for how Hiya uses AI in GTM
• Trust is built through delivery, your influence expands beyond website execution to shape broader digital strategy, experimentation culture, and how Hiya reaches customers across channels

Required

• 5–8+ years in growth engineering, frontend engineering, or product-focused web development, ideally in B2B SaaS or PLG environments
• Strong React/Next.js (or similar modern frontend framework) experience with demonstrated ability to build scalable, high-performance web applications
• Hands-on experience leading headless CMS implementations or migrations
• Proficiency with web analytics tools (Google Analytics 4, Amplitude, etc.) and implementing A/B testing and experimentation frameworks
• Strong understanding of technical SEO, GEO, AEO, and performance optimization
• Experience integrating APIs and third-party systems into web platforms
• Demonstrated ability to translate marketing strategy into technical execution and balance engineering rigor with marketing speed

PREFERRED

• Familiarity with CRM and marketing automation systems (HubSpot, Salesforce, Segment)
• Experience integrating AI APIs (OpenAI, Anthropic, etc.) or building multi-channel support solutions (chatbots, AI Voice Agent, etc.)
• Experience building multi-language and international web properties
• Strong communication and collaboration skills, with a track record of working effectively across marketing, product, and engineering teams
