Why Mozilla?

With pioneering brands like Firefox, Mozilla is the non-profit-backed technology company that has shaped the internet for the better over the last 25 years.

With a quarter of a billion people around the world using our products, we’re shaping the next 25 years of technology for the good of people, not companies.

The Mozilla Corporation is wholly owned by the non-profit 501(c) Mozilla Foundation.

This means we are only beholden to our mission, not shareholders.

Along with thousands of volunteer contributors and collaborators all over the world, Mozillians design, build and distribute software that enables people to enjoy the internet on their terms.

About this team and role:

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.

What you’ll do:

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.

What you’ll bring:

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.

Bonus

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 you’ll get:

Generous performance-based bonus plans to all eligible employees - we share in our success as one team

Rich medical, dental, and vision coverage

Generous retirement contributions with 100% immediate vesting (regardless of whether you contribute)

Quarterly all-company wellness days where everyone takes a pause together

Country specific holidays plus a day off for your birthday

One-time home office stipend

Annual professional development budget

Quarterly well-being stipend

Considerable paid parental leave

Employee referral bonus program

Other benefits (life/AD&D, disability, EAP, etc.

- varies by country)
