The opportunity

Grammarly empowers people to thrive and connect, whenever and wherever they communicate. More than 20 million people around the world use our AI-powered writing assistant every day. All of this begins with our team collaborating in a values-driven and learning-oriented environment. 

To achieve our ambitious goals, we’re looking for an experienced Front-End Software Engineer to join our collaborative Browser Extensions team, whose work directly impacts millions of users. The team is made up of curious life-long learners who get excited about solving novel technical challenges at scale. The task of the team is not to build a traditional web app but to create a seamless, thoughtful way for users to directly access Grammarly’s sophisticated AI system at any time, on any site. In a domain without established best practices, the challenge for the Browser Extensions team is to pioneer innovative and maintainable solutions that enhance the core experience of the web.

Grammarly’s engineers and researchers have the freedom to innovate and uncover breakthroughs—and, in turn, influence our product roadmap. The complexity of our technical challenges is growing rapidly as we scale our interfaces, algorithms, and infrastructure. Read more about our stack or hear from our team on our technical blog.

Your impact
  • Create a delightful user experience that scales to the entire web and meets Grammarly’s users anywhere they write.
  • Develop new features to enrich our users’ core web experience and pioneer best practices with cutting-edge web APIs beyond conventional web apps.
  • Own the full user engagement experience, from the setup flow to features that target power users.
  • Build in-product feedback cycles using our proprietary, sophisticated user engagement metrics system.
  • Continue to build your acumen in functional reactive programming, starting with TypeScript and React, and pushing the technical frontier from there.
  • Build and contribute to open-source libraries that impact millions of users every day, including Focal, our type-safe, expressive, and composable state management library for React applications.
We’re looking for someone who
  • Embodies our EAGER values—is ethical, adaptable, gritty, empathetic, and remarkable.
  • Has at least 5 years of related professional work experience.
  • Has strong software engineering fundamentals, including knowledge of algorithms and data structures 
  • Has a solid understanding of JavaScript/TypeScript, along with experience with frameworks like React or Angular (functional programming experience is a plus)
  • Has experience hacking rich text editors (like Draft.js or Quill), building browser extensions, or working with low-level browser APIs (like Selection or document.execCommand).
Support for you, professionally and personally
  • Professional growth: We hire people we trust, and we give team members autonomy to do their best work. We also support professional development with training, coaching, and regular feedback.
  • A connected team: Grammarly builds products that help people connect, and we apply this mindset to our own team. We have a highly collaborative culture supported by our EAGER values. We also take time to celebrate our colleagues and accomplishments with global, local, and team-specific events and programs.
  • Comprehensive benefits: Grammarly offers all team members competitive pay along with a benefits package that includes superior health care. We also offer ample and defined time off, catered lunches, gym and recreation stipends, admission discounts, and more.

An Insider's view of Grammarly

What’s the vibe like in the office?

Our values actually represent our team. Discussions about ethical decision-making or tweeting empathetically are common at Grammarly, and I recognize how rare that is.

Celeste

Senior Content Strategy Manager

How do you collaborate with other teams in the company?

We resolve our problems with constructive discussions that are only made possible by the level of empathy and listening skills that team members have here. It makes me happy to know I work with such exceptional people.

Maryna

Engineering Manager

What makes someone successful on your team?

On my team, we have the opportunity to face down interesting technical challenges, like building an in-house data analytics platform. I like that my work can have a major impact on achieving our company goals.

Umayah

Software Engineer

What is your vision for the company?

Writing helps us all achieve personal, professional, and academic success, but effective communication requires talent and time. It can be very challenging, and we may not always be able to effectively express our meaning, convey our intent, and be fully understood—creating a gap with our audience. We’re building Grammarly to close this gap.

Brad

CEO

What projects are you most excited about?

I always feel pumped when I see the positive feedback we get from our users. To know that your work is helping people discover a product that meaningfully improves their lives—it never gets old.

Shanik

Head of Growth
