• Partner closely with product, design, AI, and backend teams to deliver intelligent, data-driven user experiences.
• Translate customer problems into elegant frontend solutions that reduce friction and accelerate time-to-value.
• Contribute to shared component libraries and internal tooling that enable consistent, product-led growth patterns across HubSpot.
• Improve performance, reliability, and observability of frontend systems in a fast-moving environment.
• Mentor other engineers and contribute to the long-term technical strategy of the Activate product area.

We’re Looking For Someone Who

• Has strong frontend engineering experience, ideally with modern JavaScript frameworks (e.g., React) and TypeScript.
• Has built and maintained complex, user-facing applications at scale.
• Brings a strong product mindset — balancing technical excellence with customer empathy.
• Has experience designing reusable component systems or working within a design system.
• Is thoughtful about performance, accessibility, and UX quality.
• Is comfortable collaborating across disciplines in ambiguous, evolving product spaces.
• Makes pragmatic, data-informed decisions in fast-paced environments.

Nice to Have

• Exposure to AI-powered or personalization-driven UI experiences.
• Familiarity with experimentation frameworks or A/B testing.
• Experience working in micro-frontend or distributed frontend architectures.
