You will work across frontend and backend, improve the technical foundation of our web platform, and help us build scalable solutions that enable our teams to manage and publish content. Along the way, you will collaborate closely with stakeholders across design, marketing, product and engineering but with strong ownership over technical quality, long-term maintainability, and the overall direction of the platform.

• Collaborate with design, marketing, product, and engineering teams to turn business requirements into well-structured technical solutions
• Interface with back-end systems written in C++, ensuring reliable and efficient data exchange across system boundaries
• Identify opportunities to improve developer experience, reduce complexity, and raise the overall engineering standard of the platform
• Take ownership of technical tasks and help define best practices for modern web development at think-cell

What we are looking for

• Strong experience building and shipping production-grade web platforms, applications, or systems
• A proven ability to solve non-trivial technical problems and work confidently in complex web related codebases
• Strong full stack engineering skills, with solid backend experience in PHP, Laravel, or similar technologies and a frameworks
• Strong frontend fundamentals, including HTML, CSS, JavaScript and modern approaches to building maintainable user interfaces

Nice to have
