Senior Software Engineer

At Mozilla, accessibility (or a11y for short) is an integral part of our mission to ensure the internet is “open and accessible to all,” helping to empower people, regardless of their abilities, to contribute to the common good. To that end, the Accessibility Team maintains the Firefox accessibility engine used by assistive technology software, as well as other accessibility specific features such as high contrast mode support. In addition, the team seeks to guide and educate design and product teams in crafting accessible Mozilla products or features. This supports Mozilla’s ambition of creating a joyful internet for all. The Mozilla Corporation is looking for a skilled developer to work with our passionate Accessibility Team to make the web fully accessible! This is a small, hard‑working team that affects the lives of users every day. Using your C++ and systems programming expertise, you will contribute to the core Gecko web rendering engine across various operating systems, shaping Mozilla’s efforts to take Firefox accessibility to the next level. Opportunities to collaborate with other browser teams abound, and working in the open is the norm. You’ll be responsible for writing code, tests, specifications, building prototypes, solving problems, and analyzing data. You’ll get feedback from real users and synthesize it into bug reports, feature designs, and strategic direction to make the web platform even better over time. Improve the architecture, stability, correctness and performance of the core Gecko accessibility engine. Debug and fix problems in our multi-process, multi-threaded codebase. Debug OS specific issues. Build excellent working relationships with engineers and organizational leaders on other teams. Collaborate with design and front-end teams to identify, assess, and remediate accessibility issues. Influence web standards that provide or improve access to new web technology. Work in the open as part of the Mozilla open source project and engage with Mozilla’s global community. Work on infrastructure to expose the web platform to accessibility technology. Meet standards for Gecko’s memory usage and performance. Implement new web features to enable new kinds of applications and content types. Benefits Health and wellness: Mozilla covers medical, dental and vision plan premiums at 100% for U.S. and Canadian employees. Our offerings give you the options you need to manage your health — and your family’s — the way you want. Mental health: Mental health is as important as our physical health. That’s why Mozilla’s health benefits include therapy and coaching sessions to make sure our people have access to the care they need. Time away: With all of life’s demands, time away from work to disconnect and recharge is essential. In addition to country‑specific holidays (12 in the U.S. and Canada), vacation and sick time start accruing right away (specifics vary by country). Everyone also takes a pause together on quarterly all‑company wellness days, plus you get to celebrate the most personal holiday of all: your birthday. Parental leave: While Mozilla’s parental leave policies vary globally, our U.S. and Canadian‑based employees can look forward to 26 weeks of paid leave for childbearing parents and 12 weeks of paid leave for non‑childbearing parents. Financial: Mozilla is a private company, so our compensation isn’t tied to stock options or equity plans. Instead, we offer generous, performance‑based bonus plans to all regular employees to underscore that we share in our success as one team. As for retirement savings for U.S. and Canadian employees, Mozilla contributes a percentage of your eligible base salary each year to the 401(k) Plan/RRSP (regardless of whether you contribute or not), with 100% vesting.
