* Automate deployment workflows and repetitive development tasks to improve efficiency.
* Collaborate closely with design, content, and product teams to ensure seamless execution.
* Ensure accurate tracking, strong server response performance, and a high-quality user experience across all devices.
* Evaluate and responsibly incorporate AI-assisted development tools that enhance productivity without compromising code quality.
Qualifications
* 3+ years of hands-on experience building front-end applications with React.
* Advanced experience working with Headless CMS platforms, particularly Strapi (v4+;
v5 preferred).
* Proficiency with Vercel, GitHub, continuous deployment, and server-side integrations.
* Solid understanding of API configuration and consumption within Headless CMS environments.

* Demonstrated experience improving conversion rates and running A/B testing experiments.
* Strong knowledge of analytics tools and CMS integrations.
* Excellent English communication skills, both written and verbal.
Bonus Skills
* Experience integrating and customizing HubSpot APIs.
* Familiarity with SEO, CRO, and performance-driven digital strategies.
* Previous experience working in high-growth or startup environments.
* Exposure to AI-driven development workflows, frameworks, or tools.

* Flexible working hours
