Role
Who you are
- 4+ years building production web apps; strong JavaScript/TypeScript and DOM fundamentals
- Practical experience with Hotwire/Turbo + Stimulus (or adjacent expertise and willingness to ramp fast)
- Experience using CSS Frameworks and component libraries (currently we are using Tailwind and Flowbite)); strong eye for interaction design and visual polish
- Comfortable with OAuth flows and integrating REST/JSON APIs; solid grasp of async states, streaming updates, and form UX
- Performance and accessibility mindset: Core Web Vitals, a11y (ARIA, focus management), responsive design
- Testing discipline: you write tests that make refactors safer and delivery faster
- Fluency using Github
- Commitment to our values:
- Welcoming differences
- Being relationship-minded
- Practicing responsible participation
- Having grit
- You don’t need every bullet. If you build fast, accessible, beautiful web apps and care deeply about users, let’s talk
Desirable
- Google APIs (Drive Picker, Gmail scopes) and Stripe Dashboard fluency; experience surfacing webhook state via Turbo Streams
- Data‑heavy UI experience (tables, virtualized lists, CSV importers, reconciliation views)
- Experience presenting AI/LLM outputs responsibly (confidence, provenance, explanations) and building “explain/inspect” UI
- Experience with Ruby on Rails would be awesome
- Experience with Docker and Kubernetes
- Design‑system chops (tokens, theming, dark mode) and i18n
- Startup/founding‑team experience
- Experience or familiarity with bookkeeping, accounting, or taxes
What the job involves
- The New Products group is building a suite of content creation and productivity tools to help solopreneurs, freelances and small and medium businesses (SMBs) grow their customer base and work more efficiently
- As a Front-End Engineer on our small and awesome team, you will have a seat at the table for all conversations on product vision and strategy
- You will play a key role in shaping and building a new product from early prototyping, to MVPs, to finding product market fit
- You are inventive, creative, and know just how far to plan ahead for a project that operates more like a startup than an established software product
- You will have wide latitude to operate independently with your teammates
- You love to be invigorated by new challenges, you love working collaboratively, and you will have a team that supports you in making your very best contribution
- We are looking for someone who thrives in an entrepreneurial setting, is comfortable working in a small team, has a track record of delivering, and can navigate the unique challenges of building 0 to 1 products
- Lead technical front-end development of a new product line, from prototype up to business-critical high traffic products
- Develop and implement front-end for generative AI applications
- Prototype and develop early stage products with a keen eye for user experience
- Work cross-functionally with other engineers, design and product management
- Write maintainable code with tests (unit/integration/e2e) and crisp docs; partner closely with product/design/back‑end; join customer sessions to translate insights into UX
- Participate in code/design/architecture reviews and project retrospectives; clearly communicate view points and share learnings across the team
- Keep pace with new AI tools for software development, such as AI copilots
- Instrument the product: analytics events/funnels, error & latency monitoring, feature flags/experiments; use data to iterate weekly
- Design human‑in‑the‑loop interactions: inline edits, split/merge transactions, bulk approve/undo, keyboard shortcuts, optimistic UI, and audit trails
Our take
Mozilla develops a range of free and open-source software, with its most familiar product being Firefox. Operated with a mission-driven, not0for-profit ethos, Mozilla champions online privacy, open standards and user-choice.
Beyond Firefox, Mozilla has focused on privacy forward offerings such as Mozilla VPN, which allows users to browse securely without being tracked. The company has also streamlined its product portfolio to concentrate on initiatives that align closely with its core mission, ensuring resources are dedicated to improving user experiences while fostering safer, more open digital environments.
Alongside this, its impact extends into the developer and tech community, having played a pivotal role in the creation of Rust, a systems programming language celebrated for its speed and efficiency. With a loyal user base, ongoing innovation, and a clear commitment to privacy and open-source principles, Mozilla remains an influential player in the technology landscape.

Company 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.
