Introduction

We are looking for a Senior Software Engineer for one of our core CMS product teams in central Stockholm, to help us shape the future experiences of Optimizely’s products and offerings. These are exciting times: We’re at the top of industry analyst ratings and we are pushing to further improve both the PaaS and SaaS versions of our CMS, adding new and exciting capabilities. One example is in the AI space where we recently released Optimizely Opal, our always on work force, that improves productivity amongst our users. Our engineers are excited to take the product they love and have been working on for many years to the next level. And here is your opportunity to join them. Even though you consider yourself a full stack developer we do recognize that you probably lean towards frontend- or backend expertise. You would be joining a group of teams with many very senior engineers with diverse skills, so personal and cultural fit will be a key differentiator alongside skills and experience.

 

You are self-motivated and like to collaborate with your colleagues to find the best solution that solves the problem, considering architecture, the cost of development and cost of ownership. We value building robust solutions that can live on and evolve over many years, while always prioritizing spending our time on what provides the most value possible to our customers. You are comfortable with working in a fast-moving agile environment and working closely with User Experience Designers, Product Managers, and other stakeholders.

 

We work in hybrid mode and collaborate closely, in the office as well as remotely. Recently we moved into a brand-new office in an optimal commuting location at Hamngatan 26. We value work-life balance and while we are a global company and collaborate across time zones we prioritize respecting local working hours, family commitments as well taking care of your physical and mental health. We believe you will learn a lot here, we also believe that you bring new knowledge and ideas to us. We want you to thrive here for a long time, as many of us have. Optimizely is the best place to be your best!
