Job Title: Optimizely Technical Lead (Front-end)

Job Description

As a Senior Frontend Engineer, you will play a key role in delivering high-quality frontend solutions across diverse architectures. This role requires both technical expertise and the ability to bridge modern and legacy systems, ensuring consistent quality, maintainability, and performance.

You will be working closely with a single client developing a code base to serve multiple markets and purposes.

The main technology stack will be Next.js, REST API or GraphQL, TypeScript and SCSS. We also expect you to work with Storybook and a suite of automated testing tools. It is a benefit if you have experience integrating with Optimizely – and have designed websites that function for multiple markets and cultures – Read: RTL and LTR support, multilanguage support and experience shipping websites that meet accessibility (WCAG 2.2 AA), data privacy (GDPR), and regional compliance requirements.

Being a senior engineer

Being a senior engineer means you have experience leading a frontend team in a project. You seek to understand what the client is trying to achieve and take an active role in shaping the right solution, not just implementing what's handed to you. You know how to design frontend architectures that are scalable, secure, compliant, and performant. You're skilled at refining tasks, and when details are missing, you go find the answers rather than waiting for them. You care about PR quality, team processes, and how frontend work gets done. You seek out the right tool for the job rather than defaulting to what you already know. You mentor teammates, share knowledge, and help build a healthy team culture. You understand the value of testing and maintaining a tight project structure. You help prioritize tasks, keep tech debt in check, and audit projects when needed.
