About the role

Seeking a Front-End Developer proficient with HubSpot CMS to build themes, templates, and custom modules, optimize performance, and support marketing workflows across devices and browsers in a fully remote setup. Build and maintain HubSpot CMS themes, templates, and custom modules using HubL, HTML5, CSS3, and JavaScript for websites, blogs, emails, and landing pages, and all related to HubSpot. Convert wireframes/designs into responsive, accessible HubSpot theme pages and reusable components. Implement technical SEO foundations: semantic HTML, clean URL structures, proper heading hierarchy, meta tags, canonical tags, robots directives, and Open Graph/Twitter meta where relevant. Optimize Core Web Vitals and performance: minify and defer assets, image optimization (responsive images, WebP), reduce render-blocking resources, and lazy-load media. Implement and optimize HubSpot CMS features, performance, and cross-browser/device rendering; troubleshoot bugs and glitches. Configure and maintain HubSpot assets (forms, blogs, landing pages) and support content editors with scalable, easy-to-edit solutions. Collaborate with marketing, design, and stakeholders in fluent English to align requirements, branding, and user experience. Use local dev tools, version control, and debugging tools; keep assets high-performing and reliable. Optional: design HubSpot workflows and light CRM configurations aligned to front-end/data needs if experienced.

Minimum of 2–3 years of professional front-end experience with HTML5, CSS3, modern JavaScript, responsive design, and debugging. HubSpot CMS development with HubL and HubDB; experience creating custom modules and templates. Fluency in English: ability to speak, write, and listen effectively for remote teamwork, documentation, and client communication. Familiarity with RESTful APIs and integrating HubSpot with other systems is a plus for front-end integrations. Version control (e.g., Git) and comfort with command line/local development workflows. HubSpot CMS certification or completion of HubSpot Academy CMS for Developers coursework (nice to have). Experience with CRM objects, data structure awareness, and basic workflow automation within HubSpot (nice to have). Awareness of accessibility, performance, and component-driven development (design systems mindset) (nice to have). Portfolio or examples of HubSpot-based pages/emails/modules showing code quality and maintainability. Strong communication and collaboration skills; professional fluency in English.
