Job description

• This role owns the foundation that lets other software drive Firefox: the secure, reliable connection an outside tool or another team uses to act inside the browser, and the building blocks they call to do it. It enables the teams building on it — internal teams, outside AI tools — to create their own products on top. This role owns the shared layer and the strategy for it. It’s a hands-on, technical role in a fast-moving, greenfield space, so it’s as much strategy as execution
• The opportunity is broad: internal teams (Smart Window, New Products’ automated tools), outside AI tools and their users, and web developers. The three share much of the underlying technology, but each reaches its market in a different way. The mandate is to figure out what to go after, and in what order
• Own the shared foundation and the building blocks it gives other software, and make them reliable and secure
• Push the open standard (WebDriver BiDi) forward, and build Firefox-only advantages the standard won’t cover
• Design the safety controls: let a person approve actions, see when software is acting for them, and take back control
• Define the strategy for any major third-party AI assistants people already use
• Serve internal teams (Smart Window, New Products) and outside tools through one shared layer

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 US 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.
• Learning and development: We’re big believers in learning by doing, and we also want to invest in your education and development beyond your role. Every employee is eligible for an annual professional development budget. Mozillians can put it toward technical or management training, certifications, conferences and more.
• Help when you need it: Life is full of surprises; that’s why it’s important to be prepared. Mozilla provides Life/AD&D and Short and Long Term Disability insurance (offerings may vary by locale) to ensure that you and your family will have a safety net in place should you ever need it.
• Plus a bit more: A few other benefits include a quarterly wellbeing stipend (to use on those things just for you), an employee referral bonus, internet reimbursement if you’re remote, and a budget for office essentials to make working remotely ergonomically comfortable.
