Senior Web Developer

What you’ll do as a Senior Web Developer at Vanta:

• Build and maintain the company website on a modern headless CMS stack (Next.js, Sanity CMS, and Vercel), ensuring responsive design, solid performance, and a seamless user experience.
• Take ownership of features and workstreams end-to-end, delivering complex work reliably and with attention to craft.
• Collaborate closely with the Technical Lead and contribute thoughtfully to technical discussions and decisions.
• Work within and help maintain our Sanity CMS content models, schemas, and editorial workflows to support scalable, efficient content operations.
• Work closely with product, marketing, and engineering teams to integrate the website with product offerings.
• Implement and maintain analytics, A/B testing, and tracking systems to assess website performance and support data-informed decisions.
• Uphold web performance, accessibility, and SEO best practices, contributing to a high bar for Core Web Vitals and WCAG compliance across the site.
• Build and integrate third-party services and APIs into the web stack, including analytics platforms, marketing tools, and GTM/data layer implementations.
• Leverage AI-assisted development tools and workflows (e.g. Cursor, GitHub Copilot, Claude) to enhance build quality, accelerate delivery, and explore smarter solutions.
• Share knowledge and support teammates through collaboration and code review.

How to be successful in this role:

• 3–5 years of experience in web development, with hands-on professional experience in modern JavaScript frameworks, particularly Next.js (or comparable React-based frameworks).
• Solid proficiency in Next.js, with working familiarity of App Router, rendering strategies (SSG, ISR, SSR), and Vercel deployment.
• Experience with headless CMS platforms, ideally Sanity CMS — including working with schemas, GROQ queries, and structured content.
• Strong command of JavaScript/TypeScript, HTML, and CSS, with a solid understanding of the DOM, accessibility, and browser rendering.
• Proven ability to build multi-platform components (mobile and web) that are cross-browser compatible and responsive across device sizes.
• Experience building accessible (WCAG), performant (Core Web Vitals), and localization-ready web experiences.
• Familiarity with integrating third-party APIs and services into a Next.js stack, including analytics, tracking, and marketing tools.
• Comfortable with Tailwind CSS for utility-first styling, and experienced working within a component-based design system.
• Comfortable with modern developer tooling: TypeScript, CI/CD pipelines, version control (Git), and component-based development.
• Openness to and experience with AI-assisted development workflows — using tools like Cursor, GitHub Copilot, or similar to improve efficiency and code quality.
• A collaborative working style with strong communication skills — someone who engages actively, takes direction well, and contributes their perspective as part of a team.
• Good problem-solving instincts and attention to detail.
• Must be authorized to work in the U.S. without the need for current or future employer sponsorship.
• Open to using AI to amplify their skills and strengthen their work - demonstrating curiosity, a willingness to learn, and sound judgment in applying AI responsibly to improve efficiency and impact.

Nice to have:

• Prior experience participating in a CMS migration or re-platforming project (e.g., from Webflow or another monolithic CMS to a headless stack).
• Familiarity with Webflow, particularly for context around legacy content structures or migration work.
• Experience with design systems, Figma-to-code workflows, or component library development.
• Knowledge of SEO/AEO strategy and tooling for marketing-focused web properties.
