Staff Engineer

What’s the opportunity?

Intercom’s websites, Intercom.com and Fin.ai are more than just digital storefronts. They’re critical growth engines, powering demand generation, top-of-funnel analytics, and product storytelling. We are investing in strengthening the data and infrastructure layer behind these experiences to unlock deeper insights, better performance, and more scalable systems.

We’re hiring a Staff Engineer to own and elevate the middle-to-backend architecture of our marketing web stack. This is a high-impact, cross-functional role, partnering with data scientists, the GTM analytics team, marketing engineers, and platform teams to evolve how we collect, move, store, and operationalise data from our web properties.

You’ll bring deep backend and systems expertise, while also being comfortable navigating frontend codebases, supporting full stack engineers, and improving the overall developer experience for Team Web.

What will I be doing?

• Lead the design, implementation, and ownership of backend systems that power our websites, including APIs, services, data pipelines, and telemetry infrastructure.
• Collaborate closely with data science, GTM analytics, and marketing ops teams to define requirements and ship tools that support channelattribution, performance tracking, A/B testing, experimentation.
• Architect scalable solutions for event tracking and top-of-funnel analytics, ensuring data quality and consistency.
• Enable reporting across the marketing funnel.
• Improve A/B testing infrastructure, making it easy for teams to run experiments, track results, and iterate quickly.
• Partner with full stack engineers to integrate backend services into frontend experiences, ensuring reliability, observability, and performance.
• Improve our infrastructure using Terraform, AWS, and CI/CD pipelines, focusing on developer productivity, testability, and system health.
• Contribute to strategic technical direction for Team Web — identifying opportunities to improve code quality, reduce tech debt, and scale our systems.
• Coach and mentor other engineers — sharing best practices around service architecture, observability, and data engineering
• Build using the best tools in the industry. We invest heavily in AI-powered developer tools that remove friction and help you focus on solving meaningful problems.

What skills do I need?

• 10+ years of software engineering experience, with a strong emphasis on analytics and infrastructure work.
• Proven ability to design, build, and maintain scalable APIs, services, and data systems in a production environment.
• Familiarity with data pipeline technologies, streaming/batch processing, and event instrumentation best practices.
• Strong grasp of CI/CD, observability, and system reliability practices in web-scale environments.
• Experience with Vercel, cloud infrastructure (AWS) and Infrastructure as Code (e.g., Terraform).
• Comfortable with frontend architecture and tooling, while this is not a UI-heavy role, we value full stack awareness.
• Excellent collaboration and communication skills — especially when working with cross-functional teams like marketing, analytics, and data science.
• A mentorship mindset — helping level up engineers across disciplines and fostering a strong engineering culture.
• Bachelor’s degree in Computer Science, Engineering, or a related field (or equivalent experience).
