Overview

Mozilla is hiring a Software Engineer for their DOM Core team to improve web standards and user interaction. You'll work with technologies like JavaScript, HTML, and CSS. This position requires a strong understanding of web development principles.

Job Description

Who you are

You have a solid background in software engineering with experience in web technologies — you understand the intricacies of the Document Object Model (DOM) and how it impacts user interaction. You are proficient in JavaScript, HTML, and CSS, and you have a passion for improving web standards and user experiences. You thrive in collaborative environments and enjoy working with cross-functional teams to push the boundaries of what the web can achieve. You are committed to continuous learning and growth as an engineer, always seeking to enhance your skills and knowledge in the field.

Desirable

Experience with open-source projects is a plus — you understand the value of community contributions and are eager to engage with other developers. Familiarity with browser engines or web standards will set you apart, as will any experience in performance optimization or accessibility best practices.

What you'll do

As a Software Engineer on the DOM Core team, you will be responsible for implementing and improving standardized APIs related to the DOM, HTML, and user interactions. You will write code and tests, ensuring that the features you develop are robust and reliable. You will also build prototypes to explore new ideas and solve complex problems that arise during development. Your work will directly impact how users interact with the Firefox browser, making the web a better place for everyone. You will collaborate closely with other engineers, designers, and product managers to deliver high-quality features that align with Mozilla's mission.

What we offer

Mozilla offers a unique opportunity to work for a non-profit-backed technology company that prioritizes user privacy and a better internet. You will be part of a diverse and inclusive team that values collaboration and innovation. The role is fully remote, allowing you to work from anywhere in the UK. Mozilla provides competitive compensation, with salaries ranging from £51,000 to £75,000 GBP, and a supportive work environment that encourages professional development and personal growth. Join us in shaping the future of the web and making a positive impact on millions of users worldwide.
