Fin can also be combined with our Helpdesk to become a complete solution called the Intercom Customer Service Suite, which provides AI enhanced support for the more complex or high touch queries that require a human agent.

What's the opportunity?

As a Staff Frontend Engineer on our Frontend Platform team at Intercom, you’ll be responsible for defining and evolving the foundations of how Intercom builds user interfaces. Our mission is to make it faster, safer, and easier for product teams to build, iterate, and ship high-quality products at scale.

We’re modernizing our frontend stack with React, and this is your chance to set the standard, establishing patterns, mentoring engineers, and pushing for the design and architectural decisions that will shape Intercom’s frontend for years to come.

You’ll solve highly complex problems that span the whole product development org, and ensure our frontend systems, frameworks, and practices scale with the business. You’ll drive technical direction, influence cross-functional strategy, and act as both a force multiplier and an expert executor, depending on the problem at hand.

This is an opportunity to lead at the intersection of architecture, developer experience, and product enablement, while raising the bar for engineering across Intercom.

This role is ideal for engineers who thrive at the intersection of technical depth, product impact, and leadership, and who want to raise the bar for the entire engineering organization. This role focuses on building and evolving the frontend platform, not on day-to-day feature development. If your experience and interests are mainly in developing product features, this may not be the right fit, but if you’re excited by shaping architecture, tooling, and developer experience at scale, you’ll thrive here.

What will I be doing?

As a staff engineer, you will:

- Lead and deliver on the most complex and ambiguous projects, reducing risks early and ensuring execution quality.

- Set direction for our frontend React ecosystem and advocate for best practices across the company.

- Mentor and grow engineers at all levels, creating leverage through coaching, durable knowledge sharing, and role modelling the bar for technical excellence.

- Shape the culture of frontend at Intercom, championing quality, customer empathy, and long-term velocity while balancing product delivery.

- Partner with engineering and product leadership to align technical investments with business priorities, influencing roadmaps and shaping strategic trade-offs.

What skills do I need?

- 8+ years of professional experience building high-quality web applications, including impact at scale.

- Strong foundation in web fundamentals (HTML, CSS, performance, accessibility) and the ability to teach and advocate for them.

- Strong track record of enabling other engineers or product teams, through frameworks, tooling, or architectural decisions.

- Experience leading initiatives, shaping technical strategy, and driving alignment across multiple stakeholders.

- Proven ability to deliver on ambiguous, high-stakes projects, balancing speed, quality, and long-term maintainability.

- A product mindset: you understand the importance of velocity, usability, and customer impact when making engineering decisions.
