Horizon3.ai is a fast-growing cybersecurity company building NodeZero, an autonomous penetration testing platform used by enterprises, government agencies, and MSPs to proactively identify and verify exploitable attack vectors. The company is founded by former U.S. Special Operations cyber operators and startup engineers.
You will own the full technical execution of Horizon3's marketing website, treating it as a living conversion asset rather than a static brochure. This is a high-ownership, hands-on role focused on building and maintaining the marketing web presence while partnering with digital marketing, brand, design, and product marketing teams.
Key responsibilities include:
- Build and maintain WordPress pages, templates, custom post types, custom fields, and reusable components, translating designs into clean, responsive, production-ready pages.
- Write and maintain well-structured HTML, CSS, and JavaScript; build reusable templates and blocks that keep the site consistent and extensible.
- Partner with design to accurately implement Figma designs, preserving visual fidelity and interaction detail across breakpoints.
- Own site performance, Core Web Vitals, and mobile responsiveness; diagnose and fix render, load, and layout issues.
- Build landing pages, forms, and interactive elements that support demo requests and campaign conversion; implement A/B tests and CRO changes.
- Set up and maintain analytics, conversion tracking, event tags, and UTM handling via Google Tag Manager.
- Implement technical and on-page SEO improvements including semantic markup, structured data, metadata, alt text, internal linking, redirects, and site architecture.
- Implement and troubleshoot integrations with marketing and business platforms, including forms, events, recruiting tools, and consent management.
- Implement cookie consent, tracking governance, and accessibility standards (WCAG) to ensure compliance and usability.
- Manage staging, version control, and conduct cross-browser, responsive, accessibility, and regression QA before releases.
- Own plugin updates, security patches, uptime, broken-link management, and routine technical audits.
You will bring 4+ years of hands-on web development experience, ideally building B2B marketing or corporate websites. Required skills include strong proficiency in HTML, CSS, and JavaScript; deep WordPress experience including theme development and custom blocks; proven track record optimizing Core Web Vitals and page speed; experience with Google Tag Manager and analytics; working knowledge of technical SEO; comfort translating Figma designs; and disciplined approach to version control (Git) and deployment.
