Fastr is a forward-thinking technology and services company revolutionizing ecommerce and digital experiences for enterprise brands and retailers. Our platform empowers marketers and merchandisers with unparalleled creative control over their digital presence and optimizations.

You’ll work directly with some of the world’s most recognizable brands and retailers, helping them design, implement, and optimize experiences using Fastr Frontend.

• Demonstrated experience using AI tools (including ChatGPT or similar) to design, evaluate, and implement technical solutions.
• Experience working with analytics platforms, experimentation tools, or A/B testing frameworks - or the ability to confidently speak to these concepts.
• Comfort translating data into insights and using those insights to inform strategy and customer recommendations.
• Excellent communication skills - able to clearly explain technical concepts to both technical and non-technical stakeholders.
• Strong problem-solving instincts and the ability to think holistically about systems, performance, and long-term scalability.
• Experience using browser developer tools for debugging, performance analysis, and troubleshooting.
